I thought BOSE was supposed to be a good stereo! There is NO bass. I have it all the way up and can hardly get anything? Is it the speakers, the amp, or what? What can be done to make is sound better?

What kind of set up do you have? If you have bucket seats up front, then the sub in in the center console. Dont think there is a sub if you have the bench style seating up front.

Read this thread to learn lots about the Bose systems.

I just changed out my head unit and amp to Luxury units out of an Excalade. It does sound much better. My only complaint is the LUX units don't have the speed controlled volume.

I have the bucket seats. I do like the speed control volume more than I thought. What kind of amp could you replace it with?

I agree with you, parent723!! The "Premium" Bose system that comes in the "non luxury" vehicles (i.e. any full size GM truck besides the Escalade and Denali) is NOT what a Bose system should be!!! When I put in my Escalade navigation system, I had to put in a "Luxury" Bose amp from an Escalade. Lemme tell you, just swaping the amp makes all the difference in the world. Its not the speakers' faults at all!! Its that the amp driving them is crap. When I put the LUX amp in, I suddenly got like double the bass, and much much richer, clearer sound. Now remember, it wont start exploding windows a mile away, but it is just much better sounding and does really go surprisingly loud. Everyone that gets in my truck cant beleive its a "stock" system and they cant beleive how much bass can come out of a simple little 6.5" sub. (yup, its only that big...Bose likes to use secret, specially adjusted EQ's and finely tuned enclosures to give the impression of bigger, richer sound than would normally be possible from a certain size speaker. And does work...I mean some people are totally against Bose and their completely strange ways of speaker design, but I really enjoy the new "LUXURY" sound in my truck. And lux amps can be found for cheap (i got mine for 50$) on ebay!!

Ben,

What specifically did you search for on EBAY. I looked for car amps and there were a ton. Is there a specific type or model I am looking for? Thank for your help.

I typed in the model numbers that were given in the link above to the other discussion about the Bose and I got zero hits. I wonder if local car stereo shops have them for sale after removing them for aftermarket systems?

I would love to hear what the Luxury amp does.......as long as the amp and H2 radio don't cost an arm and a leg. Don't forget that you'll have to have the truck computer reconfigured to tell it that a different radio/amp is installed to get the correct soundfield. Don't you also get midrange EQ controls with the better 6-disc changer as well, or is that just on the NAV unit?

actually, you dont have to reprogram the BCM or anything. (I mean you COULD reporgram the amp to get the correct sound field for your particular cabin, but no one bothers to because chances are you would never really know the difference...also people have had amps randomly go dead after programming, so thats another reason to NOT program the lux amp) The only thing you have to change to install a lux amp is you have to change some wires on the amp connector plug. (like move some pins around) and after that, its plug and play. Yes, with the lux amp you gain the mid-range adjustment. Doesnt matter whether you do the Nav or not. Also you get diffferent DSP modes such as "DRIVER" "SPACIOUS" "REAR" and "PASSENGER".
Beleive me, it sounds SOOOOOO much better than the "Premium" Bose amp. There is no comparison. Its amazing all the difference just an amp can make. There is much more Bass and in general the sound is SO much clearer and richer. To find lux amps on ebay, search for "bose amp" "bose amplifier" "gm bose" "escalade amp" "escalade amplifier" "denali amp" and "denali amplifier"
Hope that helps!!

It is true that you lose speed compensated volume (SCV) with the LUX amp.

However, the BOSE amp has inputs for an ambient noise microphone (Adaptive Volume Control). It will adjust the volume level based on ambient noise inside the cabin. It works well. I bought the microphone out of an escalade.

I don't have the Bose system in my truck so can i still install the luxury headunit and amp?

In your case I'd just start over and go aftermarket right off the bat. I put a high power Alpine CD player in a truck I had that didn't have the Bose system and it made a huge difference. The stock speakers are not the greatest by any means, but it's surprising what a little more power can do. I'd start there and then work towards changing out the speakers.

I don't think it's possible to change to Bose (premium or lux) without doing the entire system speakers and all. I may be wrong on that, but I believe it's a different ballgame.

Yup, if you dont have Bose to begin with, its really not worth it. technically, of course its possible, but you would have to buy all of the Bose speakers, the amp, head unit, etc... You would also have to make some custom harnesses and find a place for the oddly shaped Bose sub/enclosure. For the money/effort you would spend on converting your truck to Bose, you could just go aftermarket and have with better sound at the end.

----Ben

Where the F&*% is the Class 2 data wire located on the factory radio harness that you need to tap into for the amp? I don't have the RSA in my ext. truck. Got everything wired but that. The instructions that were posted here a while back say A1, but that must be for the RSA only. It's org on the headunit harness. I'm guessing since I took out a plain single disc Bose that the ClassII never was wired to it? Where can I find a place to tap? Truck is in pieces! :help:

Well, I believe I found a Class II wire but I get no sound. Same condition as before when I powered up the radio without the Class II wired up. I can change channels, but it doesn't show any indication of when I turn the volume up and down nor does the Audio button do anything. wtf, over?

bad amp? It looks darn near new (Ebay), but the bolt holes were very slighty scuffed, making me think I was probably installed once.

Minn-Kota, run a wire from PIN “A1” of the RADIO harness (behind the dash) to hook up the class II.

Hope that helps.

Yeah, I did some more research last night and found that the org wire on A1 is indeed the ClassII wire, but I had it hooked up there and it has the same result...nothing!

I checked all my wiring over and it appears to be fine. The steering wheel will control the channels but that's it. Changing the volume on either the HU or wheel shows nothing on the HU. No sound. I'm wondering about the amp. I don't know if the radio will show change in volume on the display if the amp isn't functioning. It also won't respond to the Audio button.

Thanks

In the real world of high end audio Bose is considered a joke .

:exactly:

Well, I got the SOB working. Turned out to be the large orange power wire going to the amp. The connector for that wire was bent down some and wasn't making complete contact with the amp pins. I started wiggling wires around and it awoke! Just got the truck back together and it sounds good.

I didn't troubleshoot too much last night as it was already late and it turned out to be something pretty simple after I got after it fresh today. Buying stuff off of ebay gets you thinking you're dealing with damaged goods when it doesn't work right away. If I were to do it all again, I think I'd rip the center console out. That was a major PITA working around that. Not to mention dropping misc. items down all the convenient black holes that it provides when it's open on the top. :D I never did get the front two screws into the amp. No way you could get in there with anything yet get the screw started with my fat fingers. CensoredCensored

The only thing I was disappointed in was that there is no Midrange adjustment as was previously stated. Censored It does sound better and louder than it did with the vanilla Bose, and now I have a 6-disc in-dash to boot!

IRA51 - I know it's not top of the line and I'm betting that none of us here claim that, but if I wanted high-end I would have gutted the complete system and started over. This was a cheap upgrade and still appears stock. I may still get the PAC amplifier adaptor and throw in an amp and a couple 10's to help the low end. :grd:


Thanks to all that contributed to this project! :rockit:

agree ,B- basically O- old S- sh tty S- sound ,, thats bose to the high end , but it's all we have to work with (thats why we modify everything we get, we are happy to pay for it once only to mod. it or remove it latter at double the cost, WE ARE A NUTTY BUNCH!!! And if you want high end go Magnapan, Krell, Audio Research Hey we can afford $47,000.00 trucks to tear into ,why can,t we buy $25,000.00 amps and $20,000.00 speakers , we'll end up moding them too!!!!! Ah the INSANITY?!?!??!?!?!?!?!?!?

No midrange adjustment...are you sure?? The Lux amp and its head unit (whether you went with the nav or H2 6-disc radio) DOES have midrange adjustment...im sure of it.

Remember...if you want to use a PAC adapter to add subs, you CANT use the AOEM-GM24 adapter. It wont work. You will need the C2A-GM24 adapter. Unfortuantly, its about twice as expensive (because it has to deal with Class II data...). Doh!!

I'm pretty sure, unless it's hidden somewhere! I believe I tried every soundfield and there was no midrange adjustment. That irritates me as I was under the impression that was available and I believe it would help clean up the sound more to suit my taste. I have the H2 HU with the 15199992 amp. :help:

Yeah, I'm aware of the different PAC adapter and the price difference. I'll have to look for one if I decide to throw a couple subs in.

My 6-Disk doesn't have mid-range either. Maybe only the nav units have it?

NOOOOOOOOOOOOOOOOOW you tell me! :rolleyes:

Going in today to get the Theftloc removed. Having 6-discs at the ready is nice! Although by the time it gets done screwing around moving the disc and loading and unloading, I could have had one out of the case and loaded my old single disc HU. I suppose the reduced risk of fumbling with CD's while driving is worth it. :D

Well, I took it to the dealer to have the theftloc removed and now it doesn't work !!!! http://www.gm-trucks.com/forums/style_emoticons/default/mad.gif http://www.gm-trucks.com/forums/style_emoticons/default/mad.gif http://www.gm-trucks.com/forums/style_emoticons/default/mad.gif Now there is no soundfields available as before (spacious, driver, etc) and just talk and custom as if it were a 6-disc out of a truck. Great. The volume indication runs up and down, I can change channels and everything.....just no sound. http://www.gm-trucks.com/forums/style_emoticons/default/mad.gif

WTF did they do when they unlocked it? They told me they had to pull the code out and then relearn the radio for that VIN. I told them it was out of a H2 and that I just wanted it unlocked, but he said the VIN programming was part of the process. Man, I'm hot right now.

Oh, and according to the Tech2 there is a DTC that says there is a problem with the Class II on the amp.???? I was listening to it last night. I know it worked. For the cripes sake, I just wanted the damned thing unlocked. I suppose they smoked my amp.

:help2:

it is a very commen problem with trying to reprogram a used amp, chances are your S.O.L , the STEALER will not fix a problem for radios that are not factory installed, eaven if it is a GM. radio ,I hope you didnt pay to have them blow your amp. This is why if you search all my threads ,Iv always preached buy NEW and take the wory factor out of the equation.It may cost more but you know it will work!!!!!!!! I'll look into any thing I can to help BY THE WAY I LOVE MERL HAGGERD

Minn-Kota, I feel for you. I don't think missing the mid-range is a big deal. It still sounds way better. The dealer should not have to even touch programming on the amp.

I wonder if the tech screwed up. As I understand it, the premium and luxury head units are EXACTLY the same except for how they are programmed. The dealer should of only unlocked it, not messed with the programming.

Good luck.

One good thing remains....the damned door chimes!!!!!!!!!!!! arrrrgh...

Well, I'd like to know exactly how they are supposed to unlock the Theftloc. Everyone says it's so simple, yet the moron with the Tech2 sure did a fine job with mine! Maybe someone should post the steps on how to unlock a radio that was installed from a different vehicle so this can get cleared up. I could chew nails right now.

Anybody want $200 worth of paperweights? :mad:

Minn-kota...That is a VERY strange problem...The dealer must have done something crazy and stupid because the ONLY way to reprogram a head unit for a different amplifer style (Lux or Premium) is to hook up the radio to the GM TIS programming computers and reformat the whole stinkin' radio manually. I have NO idea why he would do that JUST TO LEARN THE VIN when its 10x easier and quicker with a Tech II.... Im 99% sure you cant do any of that radio-amp programming with only a Tech II tool. The only thing you can do with a Tech II is relearn the VIN (and program the amp for different size cabin's). The dealer is probably stupid and thought he had to hook up the radio to the TIS programming computer to relearn the VIN because I think thats what you had to do with the OLD (2002 and before) radios. (remember, the radios didnt speak Class II back then, so a Tech II tool couldnt talk to them) Its like as if you are trying to get to New Hampshire from Connecticut (where the "journy" is to relearn the VIN). Well, instead of going the direct, quick route (like as if he used a simple Tech II), he went the old, slow route that goes around Texas... SOrry for the dumb analogy haha. Some dealers are so ignorant...its not worth arguing with them if they dont do something the first time...like my dealer is great, I have been family friends with them forever, but they are 50 minutes away. So when I went to get my nav unit unlocked at the local dealer (which is a lot closer at like 15 minutes away), the idiot was laughing and trying to joke with me like "haha i wish it was that simple man...but its a huge complicated process...you need the old VIN from the vehicle it came out of...blah blah blah (same problem you had)" and so i jsut told myself, ok this guy doesnt know a thing and is not gonna change his oppinion no matter what I tell him, even if i shove the genuine printed GM tech docs (that show him how to do it in 2 minutes with a Tech II) in his face...im the customer and im stupid and dont know anything and hes the dealer and he knows it all. So I just said "oh well shucks" and walked out cause I didnt want him messing anything up. Well next day I went to MY dealer (yes..it did take some time from my day...) and asked him to do the same thing...after 10 minutes he asked me into the shop (ive never actually seen a Tech II before!!! theyre kinda cool) because he was (understandably) confused that I was trying to put a Nav into a Silverado. I explained to him that yes, it does work...you just have to do this, this, and this with the Tech II, and yes I take responsibility if it fries my BCM or something. He said ok...as long as you understand that this isnt something normal and COULD mess something up...then he did it and it worked perfectly...i was out in 3 minutes.

So long story short...if your dealer is acting stubborn about this, just go to another dealer. ALthough when the guy at your dealer programmed the radio the stupid run-around TIS way, it was as if he TOTALLY rebooted the whole radio...kinda like reformatting your whole computer hard-drive (as compared to the Tech II method which just kinda writes a new "VIN file"...sorry for another dumb analogy). And when the TIS computer reprogrammed the radio, it not only cleared the VIN, but it also cleared which kind of amp the radio was set up for. So to get the radio back to "lux" programming, you will have to take the radio back to the dealer and say "whatever you did last time, do it again, only this time, when it asks you what kind of vehicle its going into, specify a 2003 H2, NOT A SILVERADO/SIERRA!!!!!!" That way it will re-program the radio for a lux amp once again. Hopefully he didnt screw around with any of your amp settings. Dont worry about the DTC for the amp/Class II or whatever it was.. Thats just because the radio isnt communicating with the amp via the databus (because its set up to work with a Premium amp; Premium amps dont use the databus). One note: UNPLUG THE HEAD UNIT NOW!!!!! One other guy tried plugging in his old Premium head unit to see if it would work with the lux amp and it fried the lux amp...luckilly it sounds like your Lux amp is still alive because your chimes still work!! If he wont program it back, take it to a couple other dealers, tell them your situation, and if they resist, say something like "I talked to a Delco/Delphi technitian and they said to TIS program the radio for a 2003 H2 with a Class II LUX amp". If all the dealers still resist, you can always send the radio to Delco/Delphi's major place in New York and ask them to re-program it for a Lux amp again. Sorry you had to fall into this situation!! I would be steaming mad too...

---Ben

Why not just go to a Hummer dealer and ask them to reprogram for 2003 H2? At least they would know what model to look for.

As for clearing the radio of all previous info, call Specmo in Michigan. www.specmo.com (http://www.specmo.com/)
They are the Delco/Delphi Electronics gurus around here. They can clear all the crap programming, too.


Tom :pig:

Just read your post after respoonding to your PM.....

Not exactly sure what you mean by TIS. They did download some files from a PC to the Tech2 and then monkeyed around with the radio using the Tech2. I'm also worried they did program the amp. They were completely lost and I really couldn't help them as they keep the customer away from the work area. It wasn't until they were really scratching their asses before they asked me over and by then it was too late to turn back. Right now I just want the radio back to the Lux and then we'll see how we stand with the amp and then go forward from there.

Yup, thats what you do when you TIS-program something...grrrrrrr...they loaded basically a whole new "operating system" for the radio. And when they loaded the operating system, they selected, stupidly, a "Silverado/Sierra" operating system, which obviously loads the radio back into a Premium configuration. Go back and try to get them to load a 2003 H2 configuration. It has to be 2003...in mid year 2004, GM cheapened up the H2 and switched to the Premium amp.

---Ben

Minn-Kota,

Did they get your radio reprogrammed correctly yet? If not, tell them to select a Sierra Denali when programming. I saw you had posted over on the GM-Trucks forum and I don't think reprogramming or replacing the amp is the answer.

Anyway, was wondering if you got it solved.

No, I haven't done anything with it yet. I'm thinking of pulling the lux amp and putting back in the premium after rewiring back to non-lux. I'm betting my newly improved non-lux 6-disc (thanks to the dealer) will now work with it.

I believe they did try Denali when programming, but I'm starting to wonder if the radio is now vin-locked to my truck and won't act as a lux because of that? I would like to know how they got yours to work. There has to be a way. I just wish I could fiddle around with the Tech2 myself for a while and figure it out.

thoughts??

I'm wondering if it worked for you because you have a GMC and they had the Y91 code with the Denali package, whereas mine would not since it is a Silverado and there was no comparable up-level package using the Y91???

DURAtotheMAX has a Silverado, so it should have worked. I think the tech screwed up. If the head unit works with the premium amp, you will then KNOW the tech messed it up.

Keep us posted. We all want to see it work out.

I believe he has the NAV unit....

BUT!!! I also have (had) an H2 unit that I got for my dad's Tahoe when I converted it to LUX (I have since installed the nav for him). I had to get the H2 unit unlocked inside the Tahoe and it worked fine (I am fortunate to have a great dealer who did exactly what I told him; "DONT reprogram it, JUST unlock it please!!!"). Then, for kicks, before I put the nav in my Silverado, I put the H2 unit in and had them unlock it...worked fine. There is a difference between a simple VIN relearn and a full-blown radio reprogram. Yes, reprogramming the radio DOES clear the VIN, but it also mucks around with the LUX programming. So your dealer probly didnt know that you could do a simple VIN relearn without redoing the whole darn thing. (From what it seems, your dealer has never done a VIN relearn before!!! It doesnt have to be as complicated as he made it!!)

The procedure goes something like this:

1. At the Main Menu screen, select: Diagnostics.

2. At the Vehicle Identification screen, select the following options:

■ Model Year
■ LD Trk, MPV, Incomplete

3. At the System Selection Menu screen, select: Body

4. At the Vehicle Identification screen, select the following:

■ Appropriate model
■ Appropriate Air Conditioning
■ Navigation Radio

5. At the Body Screen, select: Navigation Radio.

6. At the Radio screen, select: Special Functions.

7. At the Special Functions screen, select: VIN Relearn.

8. At the VIN Relearn screen, the scan tool will display "Do you want to clear radio theft information?"

9. To begin clearing, press the soft touch key on the top right of the scan tool. The scan tool will display "Clearing Radio Theft in Progress."

10. Press EXIT on the scan tool and cycle the ignition.

Thats of-course for the Nav radio, but you just sub in the UC6 whereever it says "nav radio" I dont think it matters whether its Chevy or GMC...I dont think GM would have bothered to make it that complicated. Remember, Chevy's are really GMC's with a "Chevy Conversion Package" (RPO code X88). Look for it in your glovebox!! Its kinda funny.

The more I read about guys running into this sort of trouble (not actual problems, just a Tech II in the hands of someone who doesnt know what they are doing!) the more I want to buy a Tech II myself and start a little "programming buisness"!

---Ben

Ben, that would be a great idea, but wouldn't you have to have access to TIS programming thru the GM Tech Line, also?

Why o why weren't the dealers trained to deal with this sorta thing? Idiots running GM at work again....

Tom

When you buy a Tech II, it comes with a subscription to all the online-service manuals and it comes with all the computer CD's to load the TIS software onto a computer! Its great! Even if you dont have a tech II and you want one of the service manuals or pin-outs/wiring reference charts, you can go to AC Delco and buy however long a subscription you want. I bought a 3 day subscription for like 20 dollars when I started to do my Escalade console install so I could look up the wiring charts for the console harness. Its really nice...20 dollars gives you access to EVERY PAGE of GM online tech database. You can even download pages that you want to so you can still look at them after your subscription expires. Of course you can bet for those 3 days I was just running around everywhere on that website grabbing everything I could get my hands on before my subscription ran out!!!

---Ben

If anyone is interested in this or needs some page of procedures (for example, the seat removing procedure, console remocing procedure...), PM me and ill see if I have the page in my "collection". Or if you want ill find that website and you can buy however long a subscription you want. Its somewhere on the ACDelco page...

I've seen that theftloc removal procedure many times, but I still can't figure out how it'd work with the UC6 in my truck. Are they supposed to choose 2003 H2 for the vehicle type? Because if they choose 2003 Silverado it's going to load up with the vanilla 6-disc HU. Do you see what I mean? How does the Tech II know to load the lux version? That's the $64,000 question.

Now that mine is a premium UC6 I'm beyond that step. It might have worked to clear the VIN orginally, but now I'm basically starting from scratch and need the radio back in a H2 which would reload it with Lux, then it'd have to go back into my truck and the VIN relearn procedure done.....correctly this time.

hmmm I dont think it matters whether they select A 2003 Silverado or H2, because the Tech II doesnt have the radio programming loaded onto it all the time. If you want to reprogram a radio, you have to hook the Tech II up to a PC, go into the TIS software, select which "stuff" you want to put into the vehicle (radio programming), then press a button and the PC loads the correct and only the correct software into the Tech II. The Tech II only has like 32 MB of internal memory so it probably could oinly hold one program a t atime. Then you go back to the vehicle and program the radio with the software thats loaded into the Tech II. Ahhh you dont know how much I just want to sit down with a Tech II/TIS computer and just play with the thing! So much to learn just from messing around with it and digging into it's features. But until I save enough money to actually buy one...your guess is as good as mine for those detailed programming questions. Im really good frineds with my dealer and have known him forever...if I find the right opportunity, ill ask him if MAYBE they have an extra Tech II and maybe if I could borrow it for a day or so. I could amuse myself with that thing for hours!! Anyone have 2000$ lying around that wants to buy a Tech II!??!

You speak Blasphemy Ben. :lying:

Must be gmc is converted from a Chevy :exactly:

I have a 03 and I checked and I do have the UQ7 code in the glove box. I have a single CD player and controls in the center council for the rear passengers. I don’t think I have a sub, or if I do it is not working. The rear controls seem messed up, not that anyone uses them, but it is tough to get the thing to turn off when the kids bump into it. I was thinking of going with an aftermarket sub, but this thread makes me wonder. What is the best bang for the buck? Should I go with a Hummer system or aftermarket?

Thanks!

the lux amp only will work with a lux nav. unit, the premium nav. will not work with a lux amp. as for tis programing the non lux to work on a lux. amp it may be posible, but I would shy away from buying a lux. amp with a premium nav. or premium hu. it may be posible but most techs at a STEALER cant understand plain english let alon reprogram a radio. that is why we have all these posts about amps and hu not working. as I stated in many posts about this subject.
