About the Pioneer GM-D8701 Amp

Power galore

For power, the Pioneer GM-D8701 mono subwoofer amplifier puts out up to 800 watts RMS, so it’ll make your subwoofers happy. Two keys to unlocking great sound in a car stereo system are serious power and extensive control – and this amp’s got them both. The adjustable low-pass and fixed subsonic filters make sure your sub gets only the frequencies it was designed to play, while Pioneer circuit ensures that your bass sounds great.

Active controls

Most factory radios turn down the lower frequencies as you turn the volume up in order to minimize stress on inexpensive factory speakers. Pioneer eliminates this bass rolloff, so you get maximum bass performance when you add aftermarket amps to a factory radio. Onboard LEDs indicate optimized signal flow for inputs and outputs, plus give you a warning when a source is too loud and causing distortion. An optional wired remote lets you control bass volume from the front seat.
