## Customer Reviews

### ⭐⭐⭐⭐⭐ Great replacement for original amplifier
*by L***N on 16 March 2025*

After many Failures of my Sub woofer amp (MS309) I finally tried connecting this directly to the speaker and it sounds great with as much power as the original. Does not get hot and so small it very easy to install.

### ⭐⭐⭐⭐ Good 👍🏾 but not for me
*by A***R on 29 July 2022*

It’s good but I expected better.. nonetheless still a decent buy whomever buys one

### ⭐⭐⭐⭐⭐ Brilliant quality and great sound
*by S***S on 18 January 2024*

Bought this to fix one of 2 AE subwoofers I have. amps died in both. Didn't sound very loud in the smaller sub but the bigger 12" one sounds amazing. It is suprising just how much oomph this can give on the right speaker. Air moving and ground shaking sums it up. Absolute bargain and lovely build quality. Not as powerful as the specs suggest but is anything? With the right low impedance speaker it is awesome.
