## Description

From the manufacturer

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: 4x45w or 2x90w bridged Superb! - Been running this amp for a year now and it's been perfect. As to the other review that states there are no instructions on how to bridge this amp. There are instructions in the manual and it tells you which wires to connect, but they're not very clear and obvious. You also have to do this yourself and remove the pins from the connector and reconnect in a different order. This is very easy to do with a pin removal tool (or even a paperclip). I removed the four pins not needed anymore as I have no intention of running rear speakers and heat shrinked them, leaving only four pins connected in bridged mode for two front speakers. The only issue I encountered with install was that the outer casing picks up interference and causes noise through speakers if it touches any chassis part which is earthed. You need to make sure the amp is isolated from the body. A ground loop isolator will remove the noise but also reduces low frequencies. Mine is installed in my glove box. Takes up hardly any space as it's so small. It's isolated, well ventilated and easy to remove if any faults. Sound quality is superb for the price. I did test it with 4x45w to begin with and even 2x45w and the sound is good and a massive improvement over a stock head unit amp. Being able to bridge makes it a really versatile amp and able to drive aftermarket speakers correctly. The instructions should be clearer and a pre made off connector for bridged mode would make it easier for people to utilize this feature. Take your time and install it correctly and it's a really good amp for the price.

## 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*

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.
