they dont really handle that rms if you have a quality amp, Probably 800-1200W RMS would serve them up fine.

1,000wattsRMS atleast (800 would only give each sub 200watts), 1200watts RMS MAX... from my experience, if you read the manuel about the CVR's wiht understanding; while choosing an enclosure, you would realize that porting them will cut the RMS down from 300watts (if sealed in the rec. min enclosure) to 200watts...

so if your porting them, or using a large sealed chamber for each, then 800watts would be your safe bet....if you are gonna use 1cuft sealed chamber for each, then 1200watts is the best way to go...

if this is the amp your talking about



seems to me your gonna be wiring like so:



that amp produces
750watts RMS x 1 @4ohms

1500watts RMS x 1 @ 2ohms


you could put those CVR's (dual 4ohm) in a 0.85cuft - 1.00cuft sealed chambers, run it at 2 ohm, and just keep the gain on the amp just a little above the min. (of course you gotta do it by ear and listen for distortion, but remember, you are fittling with the level/gain that can easily send 1500watts to something that can only handle 1200watts)


or you can port all 4 cvr's (use dual 2ohm model) in 4 1.25cuft chambers

your amp can do 750watts @ 4ohms so, you would wire it how you see it in option 1:



and leave each sub only 12.5 watts short (i think the port would be HELLA LOUD)

i think your safest bet is running the subs ported... if the box is constructed the right way, it should sound like you have almost 8 subs back there ( i like the performance of the CVR's ported, i also like 'em sealed ) i only say ported so that you dont run the risk of overpowering the subs with an extra 300watts (75watts over each subs limit)... but you could run it either way you want, both ways would sound good, ported if your an SPL junky, sealed if you want a more responsive, accurate bass drop...

happy wiring...
