I really dont know much about this stuff, but my old xplod amp needs replaced and id like to get the perfect amp for my setup, which is one punch 12 inch sub...this is from foasgates website:DUAL 2 OHM OR DUAL 4 OHM 500 WATTS RMS / 1000 WATTS PEAK.

Can someone please recommend an amp? I only need to push this sub and no other speakers. Please!!

 

Here yah go. Pricey, but it will blow your doors off.

hifonics bxi 606 good power and a really good value. you can prob find one on sonicelectronix for like 140-150$...ive had 3 different hifonics amps and i think theyre great......but if price isnt a big deal theres a whole lotta other stuff you can get....im just giving a suggestion for a good amp at a good price..
