What would be a good amp to power these well. They are the Pioneer COMP DVC's. I am thinking a Rockford Punch 250 but I dunno. I dont have a very big budget either so try to keep it fairly cheap in price, not in quality. Thanx!

how many subs are you running? you might look into the jbl amps, you can get 1200+ (rms) watts for 285, 600 for 205, 300 for 145.. check out ikesound.com, jbl's are nice cheap amps that pump out a lot of power, and they're class d, so a bit more efficient...

 

I am running 2 12"s

 

the 600.1 might match up well.. you can wire up your 2 subs to 1 ohm, which the jbl can take, and they'll each get 300 watts, or slightly higher.. the jbl amps are a little underrated.. not too bad for about 200 (i think they have free shipping right now too)
