Awesome Amp!

Apr 29, 2019

Amp works flawlessly with my kicker sub! It's small and easy to hide. I've had it for about a month now, and it's working great!

Great seller, good amp

Apr 14, 2020

The amp worked great at first, but had an issue with it cutting out. Checked all wiring, and even tried a different car. Finally contacted the seller, and they helped me with the warranty to get me a new amp!

Price is worth it
