okay, i need you audio god's to help me out...i'm planning on buying a couple new comp vr's for the truck and dont know if i should go with 4ohm or 2ohm. i dont know which one's to go with becuase i have no idea what an ohm is...if someone could please explain it to me, i'd appreciate it.

thanks guys

I'm not sure what you are getting, but an ohm is an electrical unit of resistance. Voltage=currrent x resistance (V=IxR). For spaekers you need to match the impeadance (resistance) with the amp.

Ohms are the measure of resistance. The lower the resistance, the faster the amp will heat up. Most speakers are 8 or 4 ohms. Your amplifier will probalby state it's stable to 4 or 2 ohms. Most cheap amps 4, expensive ones 2. So what does this mean? If you run speakers in series( - of one to + of the other) it doubles the resistance and therefore the amp runs cooler. If you run them in parallel ( both - and both + together) it halves the resistance and the amp will heat up quicker. Generally speaking, the lower the resistance the louder the speaker will be. If you are using a good crossover network, it will have circuitry to stabilize the resistance. It's been awhile since I've been into top end car audio stuff(having $2k + worth of stuff ripped off twice will do that to you), so I'm not familiar with 2 ohm speakers, but the basics are still the same.

amp heat is one thing, which can be overcome. a good dual voice coil sub good to 2 ohms is your best bet for efficiency, if you get an amp that will support it. look at it this way, if you get an amp that will run 200W RMS @ 4 ohms and can run at 2 ohms, then your new RMS (least distortion) would be 400W @ 2ohms.

you wont find 8 ohm speakers for car audio applications, only in home audio applications.

a good monoblock amp will run them without heat concerns all day.

Like I said, I've been out of the car stereo loop for awhile, but alot of manufacturers were making 8 ohm car speakers 10-15 years ago. Man, do I feel old now.

Ohms are one of the chants that monks use.:D

Comp VRs are 4-ohm DVC.

Also, Fosgate still makes Punch 8-ohm SVCs (8, 10, 12, and 15").

CompVR's are available in 2 or 4 ohm dvc.

jzh, check out this site:

That site has some pretty good info on car audio. It looks like the site is down right now but will probably be back up in a day or two.
