The Pioneer GM-D8704 is a compact 4-channel Class D amplifier designed to deliver clean, dynamic power for your vehicle's front and rear speakers. Producing 100 watts RMS x 4 at 2 ohms or 75 watts RMS x 4 at 4 ohms, it offers impressive performance in a space-saving chassis that's easy to install. With variable high-pass and low-pass crossovers, bridgeable channel pairs, speaker-level inputs, and efficient Class D technology, the GM-D8704 is an excellent choice for upgrading both factory and aftermarket audio systems with greater clarity and output.
