KXMA1200.2 Amplifier The KXM 1200-watt stereo amplifier is built for massive full range power. KickEQ+ delivers as much as an 18dB of extra bump with a simple turn of the knob, while a powerful 24dB crossover lets you quickly tune your system to perfection. A full range RCA output allows you to easily add another amplifier without running new signal cable to the radio.
