Description

GM-D8704 Pioneer 4 Channel 1200 Watts Class D Amplifier for Car Speakers

CLASS FD 1200w 4 CHANNEL BRIDGEABLE AMPLIFIER
An amplifier shouldn’t take up too much space, especially in your car. This Class-D amp might just be what you’re looking for.

BIG POWER, SMALL SIZE
Pioneer’s new extra-efficient Class-D digital amplifiers mark a dramatic improvement in power output capability, yet are 50% smaller than the current GM-Series Class-AB amplifiers. That makes them more versatile in terms of installation as well as performance.

IMPROVED CIRCUIT DESIGN
To prevent circuit shutdown, Pioneer’s new digital amplifier circuit “Protection Control System” senses its internal temperature and automatically moderates input level accordingly. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 Ω connection. This design enhances the flexibility to connect multiple subwoofers to a system.

VARIABLE LOW PASS & HIGH PASS FILTER
For extra flexibility, variable LPF and HPF make audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-D8704 LPF and HPF are adjustable from 40 Hz to 500 Hz.

What, you DON’T own a Pioneer head unit? Well, we won’t hold it against you. In fact we’ll even help you build onto your system. The GM-D8704’s speaker level inputs allow you to connect your OEM unit (or any unit that doesn’t have the typical RCA-type inputs) without having to buy add-on adapters. So, the install goes faster, you save money, and you’ve got a Pioneer amp in your vehicle.
