GM-DX874 1,200 Watts Class D Powerhouse Amplifier, 4-Channel Amp, Variable Low-Pass Filter, Compact Design, and Remote Bass Boost Control

Awesome amplifier! Pioneer is the factory, amplified sound system in my car. I replaced all speakers and amplifier with updated Pioneer units. This amp for great in the factory location even though it's slightly bigger, but not too big that it wouldn't fit on the factory amp bracket. I recommend.

For the price it is worth it. I used a 2ohm 12 inch Subwoofer to utilize the 500 watt rms power. Blew the voice coils on 2 subs. So I found a great deal for a sundown audio classic subwoofer, it handles 700 watts rms and seems to be handling the power this little amp puts out. I think it puts out more power than 500 watts as advertised this little amp does. It aint obnoxiously loud, like I would like it to be, but it's plenty loud in the cab of the car.

Price was great ($169). I am running 4 3way Pioneers (70w) with this amp. No overheating, no glitches. Easy to hook up. Has presented no problems with my truck's charging/electrical system. Very pleased with purchase.

Pretty happy with it, used for my two kicker L7’s but will cut out when i want it louder

- 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

Port A doesn't work and seller is out of stock for an exchange will need to send back to manufacturer for repairs out of pocket

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.

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.
