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.

## Questions & Answers

**Q: I purchased this item to put in line with my pumpkin head unit and I'm getting very little difference in volume anyone have any thoughts**
A: Difficult to be sure without knowing your exact setup (line level or speaker level input) and your personal expectations regarding sound pressure levels. My personal experience has been that's its definitely louder; I mainly play it at a similar level to before but it sounds less stressed when doing so and the volume scale on the display is about a 3rd lower to achieve this loudness. This is when connected via high level speaker inputs. Perhaps if you're connecting via RCA the Pumpkin only has standard 2v outputs rather than the more common higher 4v or even 6v outputs modern after market stereos tend to have?

**Q: When you wire this in do you piggy back power off the fuse on the rear of the headunit ? Unless useing rca then straight to battery .**
A: Yes, it's safe to draw power from the same wires as the head unit, although when I did it I used a car specific hands free adapter loom rather than a piggy back fuse as this adapter also gave me the speaker connections needed for the high level input on the amplifier without having to cut any wires.

**Q: I have 2 set of focal access 6.5 at 60w rms .is it a good choice to order this amp .do i need to buy anything else golf mk7 oem stereo .advise pleas .**
A: im running 6.5s kenwoods and it sounds nice aswell as loud

**Q: Quick question i have this pioneer gm-d1004 amp with this speaker setup front door and dash alpine s-s69c  and rear door  is alpine s-s65  .is it ok**
A: They're 4ohms, so should wirk fine.

### ⭐⭐⭐⭐⭐ 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.
