KAC-9104D Kenwood Class D Mono Power Amplifier The KAC-9104D Class D Mono Power amplifier cranks out mega doses of power in a much smaller chassis size (30% smaller than previous models), so it's more adaptable to tight spaces like under seats or in trunks. The KAC-9104D also has a Dual Mono Drive connection that allows you to strap two KAC-9104D amps together to power a single subwoofer -that's 1800 Watts of power!
