Kenwood KAC-M1814

The Alpine S-A32F 4-channel amplifier is effectively two full range 2-channel amps built into one chassis, labeled A (front) and B (rear). Each section of the amp is bridgeable, so it can be wired as 4-channel, 3-channel, or 2-channel. The amp features a conformal coating on the circuit board to protect it from moisture. This allows you to use the amp for marine applications or on All-Terrain Vehicles (ATVs).
