KICKER ZX400.1 400-WATT MONO SUB AMPLIFI
This guy is small, stays cool, and gives plenty of power for the money. My birthsheet rated it at 475w rms, that 75 over what they are advertised at. Best buy sells the same amp for almost $300, and it is worth that, runs my mtx terminators flawlessly and at the perfect power for them, they make a great pair. Sub box has one line in and it is rated at 400w rms at 2 ohm, this is a mono amp with 400+w rms at 2 ohm. I also suggest the bass knob, another 25 bux that is well worth it, and also a good wiring kit,
