what amp should i use to power 10 inch kicker l7? something under $250?

Answer 1

thats a 600 watt sub,but you didnt say if it was the dual 2 or dual 4 ohm version.
dual 2 then wire it in series and get a mono amp that is 600 watts rms at 4 ohms (soundstorm 1f850)nice specs and under $100
dual 4 then get a 2 channel amp that is 300 watts per ch rms(soundstorm 700.2sl) $140
checkout onlinecarstereo.com they have good prices and reviews and specs

Answer 2

If you have the dual 4-ohm version of the L7, I'd suggest this Alpine amplifier:

http://www.amazon.com/Alpine-MRD-M605-Class-Mono-Amplifier/dp/tech-data/B00081F84Y/ref=de_a_smtd/103-5304509-5739807

It's rated for 600 watts into 2 ohms (CEA-2006 compliant), includes a subsonic filter (a must if you have a ported box) and the built-in low-pass crossover can be set for a 24dB/octave slope. Many amps come with a preset 12dB/octave low-pass crossover, but for subwoofers you'd usually want a steeper slope.

If you have a dual 2-ohm subwoofer, then check out this amp:

It's rated for 520 watts into 4 ohms, is CEA-2006 compliant, has the subsonic filter and the steeper crossover.
