Kenwood KAC-D8105 5 Channel 1600 Watts Max Full-Range Car Amplifier

The Kenwood KAC-D8105 is a compact 5-channel full-range Class D car amplifier built to power an entire system from one chassis. It is a practical solution for vehicles that need clean power for front and rear speakers plus a dedicated subwoofer channel without using multiple amplifiers.

Its compact footprint, speaker-level integration, and variable crossover controls make it a strong fit for OEM-upgrade and aftermarket builds where space, output, and system simplicity all matter. With verified output of 75W x 4 + 500W x 1 RMS at 2 ohms, it gives a real single-amp path for full-system installs.
