Key Features

Mono Block 2400watts Class D amplifier with bass remote - Pioneer GM-D9701

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, 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.


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-D9701’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.

Love it
Alex on 26/04/2022 5 star rating

Great little amp, running very well with plenty of good bass. I did have the inphase one which is recommended first, which spent most of the time of ownership in the shop getting repaired opted for this as a replacement, much happier now

A good little Amp
Gary Greenway on 18/07/2021 5 star rating

I'm currently running this amp to power a Pioneer TS-D12D2 12" Dual 2 Ohm Voice Coil Subwoofer. I must say that I am quite happy. I've currently got the sub wired up as a 4ohm load. I set the gain using my oscilloscope with a 50hz signal. I have also tried wiring the sub as a 1ohm load, and although it was obviously able to get it a litre louder (limited by a 600w rms sub) I found the sound wasn't as clean as in a 4ohm configuration. I also borrowed my friend's sub (same as mine) and wired the 2 subs up as a 2ohm load. Although my van was certainly shaking, this amp is a was a little under powered for both subs. The amp with a 2ohm load can only produce 800w rms which is 400w under the 2 subs total of 1200w rms, I think this is where people my have been feeling a little let down. I have had no over heating issues in any of the wiring configurations and have had the amp running full volume for a full 30 minutes. The amp is also mounted upside-down to the roof of my van. From my experience with this amp, I would say make sure to match it up with a correct rms sub (and this will depend on the wiring configuration/load). I would probably say, keep things within 100w of the rms, e.g. 4ohm 400-600w rms sub. 20hm load 700-900w rms sub or 2 subs to that total. 1ohm load 1100-1300w sub or 2 subs to that total. I will eventually be using this amp to power 3 x 350w rms 4ohm single voice coils shallow subs wired in parallel for a 1.33ohm load. If I have any issues I will update the review. My crosser is set as follows. Sub up to 80hz 12db slope Mids 90 to 2.5khz 6db slope Twitter 4khz 12db slope I hope someone finds the above info useful.

Returned after 7 days. Because the low end was crap. I though it was a faulty amp so I got a replacement. Replacement sounds just as crap. Returning for a refund. Will buy the IPA2001D on payday

  • Question: 19 April 2022
    Car: Audi A5 - 2007>

    Hey i got this amp and a 10” trex sub do i need to bridge the amp to get the 800rms ? And unbridge for 500 ?


    No, the amp cant be bridged as it only has one channel. You may run it on 1 ohm but it is not recommended as this amp will only run at 80% capacity which will generate a lot of heat, which can cause the amp to shut down and/or cause a clipped signal going to the subwoofer.

    Our recommendation would be to use the below to get the max out of your subs:-

    IPA3001D 1 Ohm Stable 3000 Watts Monoblock Subwoofer Amplifier
    Stinger - 1/0GA 1500W COMPLETE WIRING KIT - SSK0
    JW2D Power capacitor 2.4 Farad High performance Digital voltage displace or a secondary battery to run the amp

    I have this sub, was running Alpine R W12D4 but after 10months it gave up....which a thought was impossible. What other subs match this?


    You'll be surprised. The R-W12D4 aren't that good. The below sub will be better for you

    T-Rex12 3000W 12" Dual 2Ω Voice Coil SPL Subwoofer

    Car: Ford F150 - 2006>

    I have 2 12 inch subs at 1 ohm with 1,200 watts rms and 2,400 watts peak, will this amp be able to power it ??


    The above amp cannot power such powerful subs. You will need two of the below amplifier to power it.

    IPA3001D 1 Ohm Stable 3000 Watts Monoblock Subwoofer Amplifier
