Awesome amp! Worth the $$

I've always loved the Kicker 5 channel amps, and since my car needed a serious upgrade, I went and splurged on the Kicker LX1200.5. After the install, the music sounds amazing! Bass hits hard, music is clear, and also looks great. It comes with the control station to setup your amp, then the new Bass knob that has a bunch of features like monitor clipping and voltage. Overall I am happy and will use Kicker amps in the future as well!
