Use one amp for all four drivers. There are much less expensive amps you can use for this task.

What model/coil of CVR's do you have?

IF i wanted to power 4 cvr 12's, (rated 400 wrms?) i'd use the new premier PRS-D2000SPL.
CEA2006 Specifications:
750 Watts x 1, at 4 ohms <= 1% THD+N
1500 Watts x 1, at 2 ohms <= 1% THD+N, at 50 Hz
2000 Watts x 1, at, at 1ohms <= 1% THD+N, at 50 Hz

if your cvr's are dvc2 ohm, wire each coil in series (4 ohm each) then wire all 4 in paralel for a 1 ohm total load and they each get a real 500 watts RMS.

If your cvr's are dvc 4 ohm, wire each subs coils in paralel (2 ohm each), then series 2 subs and series the other 2 subs, then paralel the 2 groups for a total final load of 2 ohm and each sub would get 375 watts RMS.

Double check if they are dual 4 or dual 2 coiled.

Do not spend $1400 on that amp.

Not enough info. What kind of car?, What box?, What's the overall budget, including installation? What other equipment/speakers do you have, and how are they installed?

Cheaper and better don't always go together.
Value is determined by the system as a whole, and how well the design meets the goal.

Check the "for sale" section. Someone has an Ultimate T3-1000D for sale. This should have more than enough power for your application...

I wouldnt recommend that amp for 4 CVR's. It is double the RMS wattage of the subwoofers. You are gonna be looking at 1500Watts-1800Watts rms.

lol you are better off havin too much power then not enough. More power=less work for the woofers. I was runnin 3000rms to my 2 12" Fusion power plants rated at 450rms each. they did fine. It all comes down to the price factor. The ba3000.1d is a pretty sweet amp, I am running two 12.4's off one, but is that best in your budget?? I am also running a pair of bassworx 6x9 and a set of 6"components also bassworx off a bassworx 75x4 amp. My system sounds pretty sweet, but aint cheap. If you gonna do a full on Bassworx system, tell him you want a rippin deal on some the gear. Looks good for them, and yourself...
Just my 2hz though


Oh and silverbane I not tryin to talk ya bout the power thing. Just givin my opinion
