Key Features

1600W ClassD MONO Amplifier, with Bass boost remote - Pioneer GM-D8701

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 a superior high-power output.

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.

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, 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.

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.

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-D8701’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.

Bought this amplifier after reading so many good reviews about it on line. For the small size it deliveries huge power. Wicked value for money. Your staff advised to use the correct gauge cable with it. Even done me great deal on the 4 gauge kit which i needed. Big thanks to Hooshi.

  • Question: 05 September 2021
    Car: Ford Mustang - 2005>

    can i use this amplifier to run 2x 500w subs?

    Hi there,

    No, it will not be compatible.
    Which subwoofer are you after?
    Will need the subwoofer's specifications in order to advise you on a good match.

    Found Useful? Yes 

  • Question: 16 August 2021
    the focal P 25DB can be run as a pair at 2ohm 500w?

    according to the instructions can be run at 4 ohm individually, meaning 2ohm in parallel?

    have i misunderstood the instructions?


    Are you running 1 or 2 of these subs? Have a look at the below wiring diagrams.

    Found Useful? Yes 

  • Question: 16 August 2021
    hi there

    to clarify prior question the focal subs are in 500w at 2ohms
    (2 x 250w 4ohm in parallel)

    this will definitely not work?
    otherwise looking at either focal 5.1200D or the IPA2001


    The subs that you chose is a DVC (Dual Voice Coil), so in parallel, the resultant load or impedance required will be 1 ohms at 500W which the chosen amplifier will not be able to support.

    If both the subs are connected in parallel with the amplifier, then you can use the below amplifier:-

    InPhase IPA8701D 1 Ohm Stable 1600 Watts Monoblock with Subsonic Filter
