Features

A Pioneer GM D8704 Class FD 4 Channel Bridgeable Amplifier is designed to offer powerful performance without occupying excessive space, especially within your car. If you're seeking an amplifier that combines a 1-Ohm stable circuit, installation flexibility, and superior high-power output, this Class-D amplifier might be the ideal choice.

Compact Power:

Pioneer's latest Class-D digital 4 Channel Bridgeable Amplifiers deliver a significant boost in power output capabilities while being 50% smaller than the current GM-Series Class-AB amplifiers. This reduction in size enhances both installation versatility and overall performance.

Enhanced Circuit Design:

To prevent circuit shutdown, Pioneer has introduced a new digital amplifier circuit known as the "Protection Control System." This system monitors the internal temperature and adjusts the input level automatically, ensuring stable and durable circuitry. This feature reduces the risk associated with high input power, enabling the unit to achieve a 1 Ω connection. The design also allows for the flexible connection of multiple subwoofers to a system.

Adjustable Filters:

For added flexibility, the variable Low Pass Filter (LPF) and High Pass Filter (HPF) enable the adjustment of audio frequency according to subwoofer characteristics and personal listening preferences. The LPF and HPF can be adjusted within the range of 40 Hz to 500 Hz.

Speaker Level Inputs:

If you don't own a Pioneer head unit, that's not a problem. Speaker level inputs make it possible to connect your OEM unit or any unit lacking typical RCA-type inputs without the need for additional adapters. This speeds up the installation process, saves money, and ensures you have a Pioneer amplifier in your vehicle.
