Kicker 46CXA6605 CXA6605-4x90-Watt 4-Channel Full-Range Amp w/300-watt Class D Sub Channel

CX-Series Amplifiers are the perfect combination of big power, bigger flexibility and true reliability! A variable 12dB crossover, KickEQ 6dB variable bass boost and a 24dB subsonic filter on mono amps gives you the control you want - to craft the sound you love. This CX amplifier uses powerful Class A/B technology to power four mid/high-range channels and an ultra-efficient Class D power plant for the bass channel. CX-Series amps include vertical and horizontal mounting hardware, so you can show off your install style! These powerful amps work with as little as nine volts of power from your battery, and as much as 40 volts (400 watts) of speaker-level input signal.
