GM-DX971 2400W Max 1-CH Monoblock Class-D Stereo Car Audio Amplifier

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.

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.

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.

Easy to install. Very light and compact. Fits in a mini neatly. Plenty of output.

My current setup is a pair of Focal component speakers with a JVC head unit. I needed an amp that can be hidden so I chose this amp. It fits really easy behind my head unit and my speakers sound perfect now. It’s like they’ve come alive once I installed the amp but there is a catch! I strongly recommend powering the amp directly from the battery instead of using power from the existing harness since my head-unit would sometimes randomly shutdown or glitch while it was playing music and it makes sense since the amp is basically stealing power from the radio if you don’t run a wire to the battery. You need a 12 gauge wire and a fuse holder with a 20amp fuse plus crimping accessories. (I say 20amp fuse since the amp already has a 15amp internal fuse so the power wire fuse should be slightly higher) A lot of people are saying they don’t know how to bridge the amp, it was actually easy. (I will include a picture of the wiring diagram). You have to remove a few pins from the reverse ISO harness (picture included). 1) remove the pin for the white/black wire 2) remove the green/black wire and stick it in the hole where the white/black wire originally was 3) remove pin for the grey wire 4) remove pin for the violet wire and insert it where the grey wire pin originally was. I bridged my amp since I don’t use the rear speakers. (Only a front set of component speakers + sub).

Büyük bir hayal kırıklığı. Araç multimedia sına bağlandı. Sanki yokmuş gibi hiçbir katkısı olmadı. Ne ses kalitesi ne de volume da bir iyileşme yok. Boşu boşuna ısınan mavi ışığı yanan bir kutu sadece.

És un amplificador muy compacto y fácil de instalar. Yo lo he utilizado sín rca y no he oído ningun ruído al conectarlo o apargarlo, mis altavozes son unos Coral de 45wRMS y ahora puedo subir más el volumen sín que se distorsione. Si quieres dar un aumento de potencia a tus altavozes y estos no son excesivamente potentes cumple su función. Lleva el suficiente cable como para poder colocarlo en el sitio donde se desee. A parte lleva un sistema para filtrar la frequencia de agudos o graves, que ea muy facil de utilizar. La unica pega que le veo es que los cables están sin encintar y deberian estarlo ya que si rozan durante cierto tiempo con alguna pieza del coche se pueden dañar.

Petit mais puissant ! Excellent petit ampli, compact et très performant. Le son est propre, sans souffle, et la différence est nette même sur un système d’origine. Facile à installer et ne chauffe presque pas. Idéal pour ceux qui veulent un vrai gain de qualité sans prendre de place. Très satisfait !

The Pioneer GM-DX971 is an absolute beast of an amplifier! With 2,400 watts of pure power and Class-D technology, this amp delivers performance that blew me away. The 1-channel design is perfect for my setup, driving my subwoofers with clean, distortion-free bass that hits hard and deep. The variable low-pass filter is a fantastic feature, allowing me to fine-tune the sound to match my music and preferences. Despite the immense power, the amp stays surprisingly cool, thanks to its efficient design. Installation was straightforward, and the build quality is top-notch—this thing is built to last. If you’re looking for an amp that can take your sound system to the next level, the GM-DX971 is the way to go. Highly recommend it for bass lovers who demand power and clarity!

Het klinkt duidelijk beter met deze Pioneer , maar had een tandje meer verwacht. Ook was er niks in te stellen, maar dan had hij misschien te groot geweest. Al met al erg blij mee.
