Pioneer GM-DX975 - Powerhouse Amplifier with 2,000 Watts, Class-D Technology, 5-Channel, Variable Low-Pass Filter, Compact Design, and Remote Bass Boost Control

I needed an amp that had 100w x4 speakers for my Kickers that are each rated for 100w rms. This was the only amp I could find that solves that problem without costing too much. Installed it, used it, and I'm satisfied with it! Sound quality is great and it provides AMPle power. Satisfied customer. 5 stars.

Added to a 2022 Mustang to power a 10" subwoofer, and 2 two-ways in the rear deck, to upgrade the existing "Bang and Olufson" stereo. Generally good results, after using a pre-amp DSP (AudioControl LC2i) to sort out the signal from the stock head unit. Has plenty of power, setting the gain about 40% level. The low pass and high pass filters work well, and I was able to custom tune to my ears. This is not a high end Amplifier, and you can find others that will cost you double or triple. For my needs it was perfect when you need just better and cleaner sound.

This is an impressive little amp! I paired it with 93db Hertz speakers (50w rms) and they sound fantastic! I can highly recommend!

This thing is junk! Or should I say “was” junk. First off, from the beginning the remote bass knob never worked right. Lots of static and electronic noise unless you positioned the knob just right. It was so bad that I ended up disconnecting it and just adjusting the bass through the head unit. Now for the bigger problem, IT DOESNT WORK ANYMORE!!! I’ve had this thing for less than 6 months and it’s fried! Called pioneer and they want me to pay to send it in. Not happy about this thing at this point. Buy and use your own risk and don’t rely on the warranty if you do have issues with it.

I wired it up to my factory deck and it made a huge difference. Small enough to find a place in the dash for it.

added this under seat woofer to my SUV, easy to install and added the missing bottoms to my system

I don’t have an issue spending money when it’s worth it. This is worth it.Great quality, packaging was nice, the amp looks good and seems like it will hold up for a while.Paired with some kicker shallow mount tens in a Colorado in a sealed box and if I had to start all over again I would buy exactly what I bought.Running around 800rms and it tuned really well also.Plenty of juice, great features, small form factor so it’s a great behind the seat option in a truck, and seems high quality. 9/10 power and ground were hard to get seated properly. Inexperience and lack of patience may have been the issue though.

Great amp. Running a 12" sub and all speakers in my Prelude.
