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. ## Features - 4 channels, bridgeable - Plug & Play.Distortion < 0.05 - Connection also via speaker outputs of the OEM radio with automatic switch-on - Frequency response: 10-40,000 Hz ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00PAQGYKE | | Best Sellers Rank | 1,210 in Car Stereos 2,608 in Car Audio & Video Accessories | | Box Contents | Car Amplifier | | Brand Name | PIONEER | | Customer Reviews | 4.5 out of 5 stars 676 Reviews | | Item Weight | 1.03 Kilograms | | Manufacturer | Pioneer | | Manufacturer Part Number | GM-D1004 | | Model Number | GM-D1004 | | Product Warranty | 2 year manufacturer | ## Product Details - **Item dimensions L x W x H:** 38 x 64 x 181 millimetres - **Manufacturer:** Pioneer - **Maximum supply voltage:** 12 Volts - **Minimum supply voltage:** 12 Volts - **Voltage:** 45 Volts ## Images ![Pioneer GM-D1004 Easy to install, 4-channel car amp with TVC concept and input sensor (400W) , Black - Image 1](https://m.media-amazon.com/images/I/61AR8dMOF2L.jpg) ![Pioneer GM-D1004 Easy to install, 4-channel car amp with TVC concept and input sensor (400W) , Black - Image 2](https://m.media-amazon.com/images/I/71DL6l32nML.jpg) ![Pioneer GM-D1004 Easy to install, 4-channel car amp with TVC concept and input sensor (400W) , Black - Image 3](https://m.media-amazon.com/images/I/71nG8adD6cL.jpg) ![Pioneer GM-D1004 Easy to install, 4-channel car amp with TVC concept and input sensor (400W) , Black - Image 4](https://m.media-amazon.com/images/I/71be3i8zBaL.jpg) ![Pioneer GM-D1004 Easy to install, 4-channel car amp with TVC concept and input sensor (400W) , Black - Image 5](https://m.media-amazon.com/images/I/71-lYyXD80L.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent amp, extremely easy installation. *by J***P on 11 June 2025* Have this running a set of Audison APK130 component speakers fully active with signal from a Pioneer headunit.

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. ## Frequently Bought Together - Pioneer GM-D1004 4-Channel Class FD Bridgeable Car Amplifier – 400W Max Power, 45W RMS - BOSS Audio Systems KIT2 8 Gauge Complete Car Amplifier Installation Wiring Kit with Power Cables, Ground Cables, Turn-On Wire, Speaker Wire, Terminals --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/48254909-pioneer-gm-d1004-easy-to-install-4-channel-car-amp](https://www.desertcart.tn/products/48254909-pioneer-gm-d1004-easy-to-install-4-channel-car-amp) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-21*
