Key Features

Class FD 4Channel bridgeable amplifier 1200watts - Pioneer GM-D8604

Untitled Document 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 and 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-D8604 LPF and HPF are adjustable from 40 Hz to 500 Hz.

Speaker Level Inputs

What, you DON'T own a Pioneer headunit? Well, we won't hold it against you. In fact we'll even help you build onto your system. The GM-D8604'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.

  • Question: 15 February 2018
    Car: BMW 3 Series (E46) - 2005> (E90)

    Using high level (speaker) inputs the diag in the manual suggests that front and rear inputs are connected together - so how does the FADER (back to front speaker control)then work??
    thanks jp

    if your using the high level input wire supplied you wouldn't have the option of fader because you would only putting one input into the amplifier. your other option would be to use two inputs one from front and one from rear this would give you the fader option, you would be better off using RCA preouts if you have an aftermarket radio, or use a good signal converter and some RCA as most of the BMW's have high pass crossovers on the rear speakers

  • Question: 01 February 2018
    Will this amp be powerful enough to run a Hertz dieci DBX30.3 subwoofer.
    1000W peak, 250w continuous.
    Also if I added component mids & tweeters would it still be sufficient ?
    Many thanks. Russell

    depending on the coils on the subwoofer the pionner will give you 250W rms bridged at 2ohms, running component speakers on the other two channels would be fine with this amplifier

    Hi was looking at the amp to run the normal speaker in my truck but would also look at upgrading the speakers if that would be better? Also looking for a dedicated amp for a sub also?

    upgrading the speakers would definitely make a difference. you could look at the GMD8601 for your Subwoofer
