  • Fit my needs to tee!
Style: GM-DX874 - 1,200
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. ... show more

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

  • Solid 4 channel Amp -
Style: GM-DX874 - 1,200
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. ... show more

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.

  • Not a quality item from this seller
Style: GM-DX874 - 1,200
Have used this same amp before. The new one was defective. Was sent a replacement but box was all ripped and looked used. Sent it back and bought a different brand. Don't understand the used replacement. Maybe there all used. Buyer beware.

  • Pleased.
Style: GM-DX971 - 2,400W
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. ... show more

  • Good starter amp.
Style: GM-DX871 - 1,600W
- 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
