The Down4Sound JP284 is a Class D four-channel car amplifier rated at 284W per channel into 4 ohms and 460W per channel into 2 ohms, with 888W per bridged pair. Separate filters for channels 1/2 and 3/4 let you run front speakers and a bridged sub stage from one chassis. Its 10Hz–23kHz response, 95dB signal-to-noise and 150 damping factor are solid figures for a compact Class D design. It suits listeners who want one amp to drive a full active or bridged system without the size and heat of a Class AB unit.
