Pioneer GM-D9701 Mono 2400W Class-D Car Amp, with Bass Boost RemoteCategory: Pioneer Power Amps2,400 Watts Max PowerCompact Design for Versatile Installation OptionsWired Bass Boost Remote and Variable Bass Control1 Ω StablePioneer’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. 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. For extra flexibility, a variable LPF makes audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The GM-D9701 LPF is adjustable from 40 Hz to 240 Hz. Every new Pioneer Class-D amplifier has a wired bass boost remote control for optimal bass level adjustment according to listening preferences and music characteristics.

So, the install goes faster, you save money, and you’ve got a Pioneer amp in your vehicle.
