Bundle Contents

This package combines a 400-watt mono Class D amplifier with a 10-inch down-firing subwoofer and passive radiator. The 2-ohm subwoofer handles 400 watts RMS and uses forced-air cooling for consistent output. The compact amplifier includes vertical mounting hardware and Fail-safe Integration Technology-PLUS for broad radio compatibility.

Amplifier Limits

The amplifier delivers 400 watts into a single bass channel with a 25 to 200 Hz frequency response and a signal-to-noise ratio above 95 dB. Variable 12 dB crossovers and a 6 dB KickEQ bass boost shape the low end. It accepts input signals up to 40 volts, which suits most factory and aftermarket head units without extra converters.

Enclosure & Build

The enclosure uses tough MDF construction wrapped in black carpet for durability and a clean look. Down-firing orientation directs bass toward the vehicle floor, which can enhance low-frequency transfer in many cabin layouts. The amplifier measures 8-1/8" x 6-3/4" x 20.6", so installers should verify available mounting space before purchase.
