I guess it's ok for those subs. You can still get a far better amp for a lot less off eBay. Look into MTX, kicker, and audiobahn. They make quality amps at an affordable price.
i got a mtx package off there for 150 and the same package was 270 at circuit city. defintely look on ebay. and got the wires for 80 bucks less than they were going to charge me. even the guy there said it was a better idea
