Pioneer GM-DX871 - Powerhouse Amplifier with 1,600 Watts, Class-D Technology, 1-Channel, Variable Low-Pass Filter, Compact Design, and Remote Bass Boost Control

Sounds and works great!

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.

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.

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

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

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.

- Probably better for speakers than a sub- Sleek metal build that stays decently cool- Not as powerful as other amplifiers, but still good power.- Small, and can fit in tight spaces- Worth the money as a starter amplifier
