Kenwood KAC-D3104 Compact 4-Channel Class D Car Audio Amplifier 600W Max

The Kenwood KAC-D3104 is a compact 4-channel Class D amplifier built for clean full-range speaker power in vehicles where space matters. It fits well in OEM-plus upgrades, small system builds, and installs where you want more output and control than a head unit can provide without giving up valuable mounting space.

Its compact chassis, variable crossovers, and bridged capability make it a practical choice for powering front and rear speakers, running a stronger front stage, or bridging channels for higher-output applications where appropriate.
