Kicker 11DX400.4

For some people, great music is what makes life worth living. Kicker built their DX400.4 4-channel amp to send 50 watts RMS to each of your car's front and rear speakers, so you can feel the musical joy too. You can also switch the amp to 2-channel mode to run a pair of subwoofers with 200 watts RMS of bass goodness each. The built-in high- and low-pass filters adjust the amp's output so your speakers or subs sound their best, while the variable bass boost lets you add just the right amount of bump to your tunes. You want lots of power for your speakers, but this Kicker DX amp gives you something extra — clean power. Kicker's FIT™ — Fail-Safe Integration Technology — rejects noise from alternators, audio/video gear, and other car electronics for crisp, clean operation, and accepts a wide range of signals so you can hook up the DX400.4 to almost any stereo.
