Kenwood KAC-6401 Four Channel Car Stereo Amplifier

The KAC-6401 is a multi-channel power amplifier that's versatile enough to run almost any speaker configuration. Power output is 30 watts x 4, 80 watts x 2 (bridged), with a maximum outpu rating of 320 watts. The power MOSFET switching power supply uses two large secondary capacitors and a large toroidial noise filter. Features include switchable 80Hz low-pass and 150Hz high-pass electronic crossovers for the A and B channels, 2-ohm stability, speaker level inputs, a Quiet Turn-On circuit, and an extruded aluminum heat sink with sandblast finish.
