Kenwood KAC-D5101 1000W Max Power 4-Ohms Class D Mono Car Amplifier

The Kenwood KAC-D5101 is a compact Class D mono car amplifier built to deliver clean, efficient subwoofer power in vehicles where space is limited. It is a strong fit for single-subwoofer and compact bass system upgrades where you want real output without giving up much mounting space.

With 1000 watts max power, 300W RMS at 4 ohms, and 500W RMS at 2 ohms, the KAC-D5101 is designed for practical daily-use bass setups. Its variable low-pass filter, bass boost, speaker-level input, and signal-sensing turn-on also make it easier to integrate into both aftermarket and compatible factory-audio systems.
