The Pioneer GM-DX874 four-channel amplifier will deliver up to 150 watts RMS to each of your front and rear speakers for powerful music. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a compact chassis that fits in a lot of out of the way spaces.
