Kicker

Yes, ladies and gents, the Kicker's 42PXA500.1 mono amplifier is a 500-watt powerhouse that's no bigger than a brick. That's right, it's astonishingly small, which means you can get creative and stash it in nearly any nook or cranny in your car. And at that size, we bet you could find a place for it on your ATV or boat too. Kicker designed this mono amp for you open-air easy riders, with a weather-resistant enclosure, no-rust mounting hardware, a single Molex plug for all wiring, noise-killing circuitry, and plenty of power to combat wind and road noise. The amp delivers up to 500 watts RMS to a low-impedance load, so you'll have all the power you need to make the right sub thump. Kicker also gives you a low-pass filter, subsonic filter and selectable KickEQ™ Bass Boost to dial in the low frequencies to your liking.
