Review: Excellent amp, extremely easy installation. - Have this running a set of Audison APK130 component speakers fully active with signal from a Pioneer headunit. Sounds fantastic and plenty of power. Extremely simple to install. Literally plug and play if you're using a headunit with ISO connections. No need to run additional power to the battery if your stereo circuit has enough power. Unit is very small so easy to hide in or behind the dash. Comes with some mounting screws but I just used velcro to stick it to the carpet behind the glovebox. Only minor complaints would be no gain control and fixed wire lengths can limit placement and/or a pain to tuck away.
Review: What a difference - Installed this plug and play unit in my 2012 honda (you need an ISO t-harness specifically for your car - usually £10-20 if you want a plug and play install). Was a breeze and made a huge difference- 20-30mins. Prior to the installation I upgraded all four 6.5” (17cm) speakers on all four doors. I added JBL stage 2 components in front (45w rms - £60) and Cerving Vega red 2 ways in rear (65w rms - £100) There was no bass and the speakers weren’t loud. Not a surprise as the factory head unit puts out 10w rms per channel tops. So not enough for the speakers that I installed. But after adding this compact amp, which beautifully fit behind the head unit, the audio is so loud that is impossible to listen to it at max volume. I tried it, and there was no distortion. On youtube I’ve see this amp tested. And it truly provides over 45Wx4. The test showed over 50W rms per channel. The amp also doesn’t get warm. And most importantly, nobody would guess that my 2012 car with a factory head unit has an upgraded system until they hear it. I did not have to cut or splice any of the factory wires. There are no crackles, pops or unwanted noise from the amp. It is perfect. I have plenty of mid bass with the speakers I purchased and they will do. But if I wanted to, I could also add a subwoofer. But I am very happy with the outcome and will keep things as is. Hope this review helps.

## Features

- Maximum Power Output - Class D amplifiers can deliver high power output, and the GM-DX971 is no exception with its maximum power output of 2,400 watts. This powerful amplification allows for dynamic and impactful sound reproduction.
- Class D Amplification - These are known for high efficiency, converting a higher percentage of input power into output power compared to other amplifier classes. This efficiency results in less power wastage and reduced heat generation.

## Questions & Answers

**Q: Will this amp power 2 10in 4ohm 600rms subs**
A: You'll only get 400W RMS delivered to each sub. If you could get subs with dual voice coils at 4 ohms each,  then they will have a parallel combination of 2 ohms per sub. Then you will see the 600WRMS for each sub.

**Q: What's the difference between the gmdx971 and the gmd9701?**
A: The difference between the 971 and the 9701 is the 971 has hold plated rca's and the 9701 does not. God plated is always a better conductor which means less interference when it comes to connections and sound quality and distribution

**Q: Description says 1 channel amp, the pictures show 2 channel. Which is it?**
A: It is a 1 channel amplifier. It has two terminals that are really only one channel. This is so you can hook up two subs in parallel at the amp instead of on the speakers. If you are hooking up only one sub, it doesn't matter what terminals you hook up to since its really just one channel.

**Q: What is the wattage at 4ohm, and are the 2 channels visible on the amp bridged?**
A: This amp cannot be bridged its a class D Amplifier which means both channels have same output, you would have to look at specs

### ⭐⭐⭐⭐⭐ What a difference
*by K***S on 3 September 2024*

### ⭐⭐⭐⭐⭐ Transparent in sound and operation (most of the time)
*by S***S on 23 December 2019*

Fulfilled my expectations. Tonally it seems no different than the factory head unit, which just indicates its high level of transparency (a good thing). It's capable of delivering significantly more power than the factory head unit and this has enabled me to fit some better sounding after market speakers that were not quite as efficient as the factory speakers and still turn it up when the mood takes. Its not capable of blasting huge SPL, but I doubt anyone considering this would be expecting that. The compact size meant I managed to find a perfect spot for it behind the glove box. The high pass switches should come in handy when I fit a small subwoofer as it should stop the door speakers having to work so hard hopefully further improving sound quality. The only slight niggle is that my car has stop / start and in traffic there can be a momentary interruption to the sound when the car starts back up, which was not an issue with the factory head unit on its own. Also if the volume is very high when the stop / start activates the sound can cut out entirely as the amplifier senses the voltage drop and puts itself in protection mode. Not a big deal for me as its quite rare for me to listen at very high volume, but something to bear in mind if you do enjoy your music very loud.
