Pioneer GM-D8704 1200 Watts Max. Class-D 4-Channel Bridgeable Amplifier with Wired Bass Boost Remote

• An amplifier shouldn’t take up too much space, especially in your car. 
• The GM-D8704 might just be what you’re looking for. It combines a 1-Ohm stable circuit, installation flexibility, and superior high-power output.
• For Extra flexibility, variable LPF & HPF make audio frequency more adjustable according to subwoofer characteristics and personal listening preferences.
• Every new class D Amplifier has a Bass Boost Remote Controller for optimal bass level adjustment according to listening preferences and music characteristics.
• 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 a 1-ohm connection. This design enhances the flexibility to connect multiple subwoofers to a system.
• Pioneer Class D Amplifier automatically selects an input signal mode between the RCA Level and the speaker level selecting an input signal.
