i dont know how many to put in

Re: i dont know how many to put in

Personally i would sell the 2 channel JBL and get a Pioneer Premier or Kicker Monoblock.

The JBL is a monoblock amp. The two speaker terminals are wired in parallel on the inside.

And ahank1, that's what I was afraid of. They are dual 4 ohm subwoofers. And you're amp makes maximum power on a 2 ohm final load. Sooooo... with only two subwoofers your choices are:

2 DVC drivers with Voice Coils in Series / Parallel
Connecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:
Dual-6 Ohm Subwoofers: 6 Ohms
Dual-4 Ohm Subwoofer: 4 Ohms
Dual-2 Ohm Subwoofer: 2 Ohms
Dual-1.5 Ohm Subwoofer: 1.5 Ohms


OR.....

2 DVC drivers with Voice Coils in Parallel / Parallel
Connecting the voice coils of each driver in parallel (+ to +, - to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:
Dual-6 Ohm Subwoofers: 1.5 Ohms
Dual-4 Ohm Subwoofers: 1 Ohm
Dual-2 Ohm Subwoofers: 0.5 Ohm
Dual-1.5 Ohm Subwoofer: 0.38 Ohms



If you'll note the "dual-4 Ohm Subwoofer" lines with each picture. Your choices for final loads are 1 ohm and 4 ohms. With a 1 ohm load, odds are the amp will kick into protection almost right away. The owners manual clearly states that it is not 1 ohm stable. A 4 ohm load will work, however you wont be using the full potential of the amp. So I strongly advise doing what you can to squeeze three subs in there. You can then use this scheme:
3 DVC drivers with Voice Coils in Series / Parallel
Connecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:
Dual-6 Ohm Subwoofers: 4 Ohms
Dual-4 Ohm Subwoofers: 2.67 Ohms
Dual-2 Ohm Subwoofers: 1.33 Ohms
Dual-1.5 Ohm Subwoofer: 1 Ohm


You would be running a 2.67ohm load to your amp. This will allow the amp to produce more power to now, more subwoofers. So an extra sub with extra power to boot. Win Win. Benefit Benefit. Best bang for the buck. However you want to put it. And if you get crazy and find a way to cram all four in.... an exact 2 ohm load would be possible. Again, another sub and more power to boot.:naughty: It's just the 2 subwoofer setup that will have issues. 1, 3 or 4 of them is the way to go.

Re: i dont know how many to put in

just wondering if anyone has a picture of 3/4 12s in a camaro lol.. i need to see what i might be working with lol

oh and i might just do two i am not looking for ear bleeding bass or anything like that.. i dont even really listen to bass music. i listen to alot of punk and what not....lol but i may do 4 just for show lol

Re: i dont know how many to put in

Depends what you want to do.
Personally I'd stick one in and sell the rest. My single 10" hits as hard as i could ever want.

Almost the same here. I'm pushing a single inverted 12" 1100W Sony Xplod with (I think) a 600 or 650W max, and I think 250 or 350 continuous power american Pro amp. It hits hard. I still think I'm going to eventually wire in the other 12, though. So 2 at most. I would, anyway. 4 is overkill.

Re: i dont know how many to put in

what if i did somthing like this... would that work

Re: i dont know how many to put in

That would technically hold the speakers, but I don't see enough specs to tell if the airspace is right for your subs. Read the outside dimensions and measure some spaces inside your car. I don't know where a box as big as that would go (trunk well maybe?)

I personally would install 1 in a box like mine (2.25 cubic feet accross the rear hump). Crutchfield lists the airspace recommendations at 1-4.6 cubic feet for sealed box for a '07 CVR12.

Or, go with http://www.subthump.com/acamarowell.htm and put 1 in instead of 2. Wire the 2 voice coils on the single sub in parallel for 2 ohm load to the amp and rock out!

Even if you want to try 2 subs, a 4 ohm load on that amp with 2 of those subs should still be LOUD. Try it a couple of ways and see what sounds best :)

For example:
I've got 2 crappy 10's on a 220W jensen amp, and that setup will shake the bodywork, so 2 CVR12s hooked up to that beast of an amp should shake your house from the driveway...even at 4 ohms load. The most important part though, is having the right sized enclosure.

Re: i dont know how many to put in

so as of right now i am going to run one for a while...then once i figure out a way try and slam 3 into it.... but time is short and i just want it in right now lol... is there any way i should wire that in special like ???? + to + /or/ + to -

Re: i dont know how many to put in

my friend put 6 of these in his camaro but it was the newer cvr the chrome one.

Re: i dont know how many to put in

i have a picture of his when he had four but not when he had six <img>http://b3.ac-images.myspacecdn.com/00740/33/93/740433933_l.jpg</img>

Re: i dont know how many to put in

I've heard good things about subthump as well and I plan on buying 2 stealth boxes from them I just can't decide what size

Come on now.... let's be real here. I've had more setups in the f-bod then I can count. That's going a little far....

hank, wire both positives together then to the positive output on the amp. Same for the negatives. KEEP THE GAIN LOW.

Ok, maybe shaking the house is a little exaggerated :p

But vibrating the bodywork isn't. You can't see it, but you can hear it.

In any case, even at the 4 ohm load, 2 of those 12s on that amp should be pretty stout. 1 @ 2 ohms would be plenty for most people, and the amp shouldn't even be stressin' so it ought to last a LONG time too.

Re: i dont know how many to put in

You have to define 'shake the house.' I have two 10" L7's powered by a zx1500.1 and i can rattle my garage windows and some stuff in it without much effort with the hatch open. Thats with me parked about 20 feet away.


Don't get me wrong, stuff isn't falling off the walls and breaking but you can still hear stuff rattle.

Re: i dont know how many to put in

its all a matter of opinion but i strongly believe 1 12" sub is perfect for a Fbody due to the t-top compartment it really amplifies the sound

Hearing stuff rattle on the walls is plenty of house-shakin' for me :)

Sounds like a sweet setup.

Re: i dont know how many to put in

I would do one twelve in there that would be plenty loud enough especially with that amp.
