Quick Overview The Pioneer GM-DX874 four-channel amplifier delivers 100 watts RMS at 4 ohms to each of your front and rear speakers for powerful music. CTA-2006 compliant, this highly efficient Class D technology provides impressive, high-quality power in a compact chassis. The frequency response extends up to 50,000 Hz, supporting crystal-clear Hi-Res Audio Certified playback. The GM-DX874 uses high-grade electronic components and gold-plated RCA connections to ensure maximum performance.

You can configure your amplifier into 3-channel mode (4 ohm loads) to create a strong front soundstage (2x 75 watts RMS) with tight bass from the bridged subwoofer (1x 300 watts RMS). The speaker-level inputs allow you to install this amp in a factory system without RCA connections. Built-in high-pass and low-pass filters let you optimize the sound for your vehicle's interior. A wired bass control remote also lets you easily control the amount of bass from the subwoofer output (SW).
