Kicker CXA3004

4-channel car amplifier — 40 watts RMS x 4

Kicker’s CX300.4 4-channel amplifier delivers 40 watts RMS to each of your front and rear speakers, or you can drive a couple of subs with up to 150 watts RMS each in 2-channel mode. And they don’t cut any corners building this amp, using oversized transistors, special transformers, and a heavy-duty heat sink to bring you reliable power that won’t fade when you push your system hard. Built-in high- and low-pass filters help you sculpt the sound to get the most out of your system, while variable bass boosts allow you to add some low-end punch to your front and rear channels separately.
