Pioneer GM-DX874 4-channel car amplifier — 100 watts RMS x 4

Product details

Cool power

Pioneer's handsome GM-DX874 four-channel amplifier will deliver 100 watts RMS to each of your front and rear speakers, for powerful music that'll make every ride a pleasure. 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. The frequency response of this amplifier stretches up to 50,000 Hz, so it'll support crystal-clear, Hi-Res playback. Pioneer uses high-grade electronic parts and gold-plated RCA connections to ensure maximum performance.

Convertible

If you're building a big system in stages, you can use this versatile amp at first to drive a pair of speakers with the front two channels while bridging the rear channels together to power a subwoofer with up to 300 watts RMS. Later on, you can get a separate amplifier for your sub, and switch this amp over to run all four of your full-range speakers.

Connections and tuning for all occasions

Speaker-level inputs allow you to install this amp in a factory system with no RCA connections — the amplifier switches its input mode automatically when it detects the high-level signal, eliminating the need to run a turn-on lead to your receiver or fuse box. Built-in high- and low-pass filters let you adjust the sound for your vehicle's interior, whether you're driving speakers or subs.
