I've looked at all the older threads, and only found the odd picture to give people ideas for their systems. I used to have a 1 - 10" infinity sub under the seat in my old CC, but never thought it was enough. I love big bass, and wanted to go with 2 - 10"s - the stereo shop said that there was not enough room - BS. My first attempt in my new truck I went with a sealed box, and then changed to a ported. Both boxes were easy to build (1.85 cf), and it only took the weekend to do the whole job + install. I am now very pleased with it, and don't have to crank it wide open to be satisfied.

The sub options are limited do to the mounting depth avaliable, and the power rating I was looking for. I opted for conventional subs over shall mount ones because they hit harder and have better sound quality. The subs are Hertz High Energy DVC 10"s - 300W RMS, 500W peak. The amp is a JBL Power Series 580W RMS @ 4ohms - 1200W peak. It's loud as hell! Here are some pictures - if anyone has any questions just ask.

Everyone else post your pictures too!:nopics:

Other subs that will work that I tried:

-Earthquake 10"s - $100 each, fried voice coils in both! But loud! - not warrantied! Told me I didn't properly break them in. Got way to HOT!
-Hertz Energy 10"s - $250 each, still couldn't handle the power - warrantied.

The subs need to be 5.5" or under mounting depth to fit! Most subs this shallow will not be rated for much power. The Hertz High Energy subs I have now are awsome, but exspensive. They hit hard & loud, and are very tight & responsive even in my ported enclosure. I would say they are the best subs I have ever owned, and I've owned a lot over the years.

Not enough room... pft. I have 3 JL 10W3V2s behind my rear seat of my crew cab.

The boxs I built were both 1.85cf and match the factory spects for the subs. The ports are 3"X10.2"X2 and were calculated on the computer tuned for 55Htz. It sounds great, there is enough room! Just got to find the right subs.

huthuthut Post some pictures of your 3-JL 10"s.:)

You don't need big woofers to have big sound.

Are those 8"s or 6"s? What's there power rating, and what are you feeding them? Do they hit the deep low notes well? Looks good!:D

6W0's and the 5th channel of a 5-channel MB Quart amp powers them. I can't remember what the port is tuned to, but it plays pretty low.

Had four 8" diamond audio subs in a ported box and right at 600watts at 12volts on them. then went with a blowthru 3 15"s, and working on the next design.

I've been trying to come up with a design to do 2 10's behind the seat. I know this can be done (I currently have 2 in a quick custom box I made about a year ago), but I want to do something custom out of fiberglass. My idea was to point the magnets into the back lower corners of the cab behind the seat so the subs are firing at a 45° angle towards the dome light. I haven't been able to check for clearance yet (I'm currently deployed), but plan to look into it when I get back home at the end of the month.

Anyone try this? It seems that this may give you a little more room than the conventional sub position.

Awesome set up. I'm getting ready to do my stereo in a week or so. I picked up two sub/box combos second hand. Both are just single 10. I think i'm going to run the behind the seat one for now and then build a box for two 10s behind the seat down the road. I wish I could hear some of your setups! They look sweet though.

noticed no one is saying anything about a center console sub package. This is what I plan on building since I put my amps behind the back seat. Hope I didnt make a bad move.

Its doable. Was thinking of doing 4 captains chairs with a fiberglass center console flowing down from the dash toback wall with some subs inverted out of the console.

I've got 2 Pioneer 12" low profile subs behind my rear seat, and the amp mounted under the seat in the center... Pics in my garage...

Any pics of the building process? I'm no sub box builder, so forgive my ignorance. Did you use wood, then coat with fibreglass or something? It looks great. I thought about doing the same, but using a single 12" sub. I had this in my reg cab (JL w9), and it hit real nice. I really don't need this truck to boom, so I figured with the difference in airspace, 1 should be suffeciant for what I want. I'd also like to do this with my stock deck. What do you think?

I honestly don't think this can be done with a 12" sub. I don't have measurements on the 12w9, but I would imagine that its depth is just too deep to mount behind the seat. My cheap 10's barely fit. I had to sand some of the 3/4" mdf behind the magnet to get them to mount. I still don't feel I have enough room in front of the subs.

The stock stereo is fine, but if you have bose (like I do) then you will have to buy an adapter, as the output level is too low from behind the radio. I'm almost at the point where I'm ready to rip out the bose and go completely aftermarket.

Can anyone tell me if there is room to mount a 10 at an angle in the lower back corner of the CC? That is my only hope - otherwise I may go with 4 8" subs.

i managed to fit a single 10" audiobahn woofer in a factory spec'd box i built between the seats, behind the center console. mind you, this is a reg cab so it is tight. thius woofer is huge too: 9" deep, 62 lbs with a 1200watt rms rating and a 1900 watt peak. it being powered by a jbl that is a single channel, 1600 watt amp, and it's more than loud enough to hurt. i'll get some pics of it later......
point of this is: who needs a backseat?? get yourself an mtx jackhammer and fill that backseat up...

Yes you can fit a 12 I have a treo ss 12" in the rear check my garage by the way I have had many setups in my truck to include 2 pioneer pancake 12", 3 jl audio 10",4 re 8",and 4 image dynamic 8" and the 12" treo I have now sounds the best for all music, as I listen to rock, hip hop, country and classic rock

ERO,

You're right, it can be done, but not with the average 12" sub. I didn't see any pictures of your other setups you mentioned. Do you happen to have any of them still? I'm always looking for ideas...

I'm sorry, I was dumb enough that I didn't take any pictures untell I was done.:duh:It's fairly simple, the hardest part was getting the angles cut properly. There is no fiberglass, all 5/8" MDF, but if you are going with a sealed enclosure you should use 3/4" to prevent wall flex.

Before assembling the rear wall, you need to router out behind the woofers to get the needed depth.(if you use 3/4" MDF router 1/2" deep - leave 1/4" material remaining - just a square were the magnet will sit) You should have @ least 1/2" - 1" space between your woofers and the rear wall for appropriate cooling - there is a vent ususally in the middle of the back of the magnet. If it's against the back of the box, it will suck in it's own hot air and overheat the voice coils!

To install the rear seat must be removed. Rear equalizer vents must be removed - not needed, just vent interior air when doors shut. Remove all the piss flaps behind seat. Remove carpet from rear of cab - install some dynomat to deaden steel. Metal tabs for piss flaps must be cut off with dremmel of side grinder - cover the rest of the carpet with a towel to prevent unwanted burns! The metal tabs between seats where the piss flaps were connected will also have to be cut off to make room - subs will sit near bottom, the lower the better to increase box depth for subs. + it will give more excursion room between the back seat!

The overall box volume is roughly 1.8cf. It will take a little bit of using your head to figure out angles and cuts, but the outside dimensions are 56" long - 14.75" tall - 5" deep @ the top - 7" deep @ the bottom. With the routering done behind the subs you will have 5.75" - 6" mounting depth, but remember that you should leave some breathing room for the vents!;) This box will fit exactly into the hole, it's snug but looks great!

If you are struggling and can't figure it out from these spects, just PM me and I will help you out some more. The best way is to get the rough cuts done at the hardware store 1"-3" bigger than you need to make it easier to handle at home on a smaller table saw. If you do your planning right, it will only take one 4'x8' sheet of MDF. I just glued and air nailed it together, but you might want to throw in some screws for a sealed box to prevent a possable blowout. I also mounted it to the back of the cab with 2 - 1.5"x 3/4" bolts - but you have to use a hole saw to cut holes into your box to get the socket on, but is very secure and will never move! Best of luck, have fun!:)

The rest of my system is the stock BOSE system, I used the pac adaptor. It sounds great, and you can turn the bass down on the head unit to prevent distortion on the factory door speakers at higher volumes. I usually have the volume turned up 7/8 of the way, bass 1/2 way and it's very clean and super loud.
I would go with an aftermarket deck, but didn't want to spend the money right now + I didn't want to mess with On* - and steering wheel controls, it can be done but cost lots of money for the adaptors! And I have XM radio built into the factory deck already.

A single JL 12W6 in a custom built console that replaced the center seat in my truck. Designed and built myself, but no pics during the build process. Pics in my garage.:D

I have the JL stealth box in my truck, I had the split bench , I lost the seat ( not that it matters) but I still retain the litle tray for small things and paperwork. i'm running it off of a phoenix gold 600 and it definately does a fine job on its own, but I have it backed up with an alumipro M -16 for when i'm really feeling noisy. theres some pics in my garage.

a buddy of mine just got 4 10" subs installed in his 06 1500 CC. he has 2 mounted behind the seat and the other 2 mounted under the outside parts of the back seat. he has the amp in the center under the seat. ill get pics next time i work on his shift. sounds rather good to me but im not sure what is supposed to sound good. i dont have enough experience to to tell you that.

do any of you think i can fit 2 10' l7's? the square solobarics.... i have some lying around and would love to fit those puppy's behind my rear seat.

Did you notice much gain when you went from a sealed to a ported box?

I am looking at doing either 4 image dynamic 10's in a sealed box or two ID 10's in a ported box.

see that imprint in the back of your seat? that is NOT good! the suround suspension of those subs extend a good bit past the mounting flange. that suspension is hitting your seat, and probably sideloading the whole thing. trust me from expirience when I say that will kill the voice coil rather quickly.

That is bad huthuthut, I noticed that too right away! Clearance is very important with high exscursion subs. It will do damage eventually, and toast your voice coils! It's a very nice box, looks like a stereo shop job, hopefully they will warranty it if something happens.

I switched subs to the High Energy from the Energy line when I changed boxes, so I couldn't say that it was the box that made the difference. The reason I switched was that I was pushing them too hard in the sealed box - too much excursion. A little too much power. I also wanted a little more bass, and switching to a ported box will give you 3dB more than sealed. The salesman wouldn't sell me the High Energy's with the sealed box because I didn't have the back of the box routered out for venting room, and he wouldn't warranty them if they burnt up - which he said they WILL! So after blowing up the Energy's I built a ported box and moved the woofers down 1" and routered the back, increasing my mounting depth to just under 6". He then let me trade up when I had them warrantied to the High Energy subs. It's way louder now, I never had it measured - but everything vibrates, and the change moves around in my cup holders.

SKYHIGHHD - the Kickers will fit if they are less than 5.5" mounting depth - I don't think they are?

The most important thing with subs is to have them in the proper size box, 2 - 10's in the proper size box, will sound better than 4 - 10's in the wrong size box and it would be a waste of money.;) There is only 1.85cf of space behind the seat, unless you go higher up to the bottom of the window. This will require fiberglass or some really crafty wood work. Just keep it simple, get the right woofers and it will be plenty loud enough. I strongly recommend the Hertz High Energys, they are top of the line but not cheep - well worth the money.:D

You can gain more space behind the rear seat by re-drilling the seat rails. I've built several boxes for trucks that I've done that to.

Check my garage.....

I'm running 3 Rockford Fosgate P2 10" sealed enclosures I built myself. They hit HARD and LOW. I too love the sound of a JL sub just wanted to try FG this time. Also have a set of Kicker 12" That might fit, might have to play around w/ box configurations to see if they will fit PROPERLY with enough air space. Next thing is to build a nice enclosed amp rack under the seat w/ plexiglass window on top, built in fans for cooling the amps and, MAYBE alittle neon for accent!

SKYHIGHHD-The answer to you question is NO, I wanted to run Solo Baric so bad I could taste it, but when it came right down to it, it was a no go. And I asked several different people who have been doing this for years. I even have a friend who use to be and engineer for Qlogic and Stillwater designs look at the possibilty of putting two L7's or L5's behind the seat. You could fit them by milling out the back of the box but then the integrity of the box wouldn't withstand the pounding the Solo's would put on the box. So if someone has been able to accomplish this task I would be very curious as to how well the set up was done, and how long it will last! Although Kicker Comps might not be out of the Picture, if you didn't mind a single coil sub!


PS: Couldn't get the pic in my garage to upload, sorry!

See my problem is that I need to be able to fully fold the rear seats down. If I was to re-drill the seats, I doubt that they would fold forward, and if I go the under-seat route, the seatbacks wouldn't fold down. I think I'm pretty much limited to what little room I have right now.

Hey guys just my 2 cents here. I installed a very high end stereo system In my 05hd lly crew cab using a subthump.com dual 10in sub box. I was the first with him to design this box and let me tell ya It pounds very tight!! I installed two alpine type r's drivin by a ppi 1500 watt mono sub amp. 4 top of the line 6.5in mb quarts in the doors powered by a ppi 480. Set up properly It sounds amazing!!!!! Unfortunatly I just traded truck and now have speakes and box for sale. Check out subthump.com and click on installs you will see my setup under c.j.'s crew cab install

Type Rs are high end?):h


I've seen 4 ID 12s behind the seat and I have 4 ID 8s under mine forward firing ya just got to move the seat some.
