Pioneer GM-D8701 Class D Mono Amplifier (RMS: 300W (4Ω) 500W (2Ω) 800W (1Ω)

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. It combines a 1-Ohm stable circuit, installation flexibility, and superior high-power output.

Bass Boost Remote
    Every new class D Amplifier has a Bass Boost Remote Controller for optimal bass level adjustment according to
listening preferences and music characteristics.

Highly Reliable 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-ohm connection. This design enhances the flexibility to connect multiple subwoofers to a system.

Variable LPF
    For extra flexibility, variable LPF make audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-D8701 LPF is adjustable from 40 Hz to 240 Hz.

Automatic Signal Sensing & Turn ON
    Pioneer Class D Amplifier automatically select an input signal mode between the RCA Level and the speaker level selecting an input signal.
