## Customer Reviews

### ⭐⭐⭐⭐⭐ Compact and all I needed!
*by S***Y on July 29, 2025*

Powers my 10 inch home theater car subwoofer with the right amount of power. Easy to adjust gain controls and is powered by a 12 volt power supply I also reviewed on here. Great match of power, small and compact. Well worth the money. Sound quality is punch and perfect for my subwoofer. Took 10 minutes to install and works great!

### ⭐⭐⭐⭐⭐ Nice power in a compact amp.
*by D***T on July 22, 2025*

Such an amazing little amp. I connected it to a powered Kenwood tube sub whose internal amp had stopped working. This thing rocks louder than the original and stays cool while doing so.

### ⭐⭐⭐⭐ Great budget friendly amp
*by B***N on July 9, 2025*

Do not use an fm transmitter for Bluetooth with the high level input. You will get static, use a headunit, or direct connect to phoneOther than that amp, can’t beat it for $46This thing is solidPowering 2 12s just fine
