### ⭐⭐⭐⭐⭐ Great little amp
*by A***K on 3 July 2026*

For the money, this is a no brainer to step up from junk internal head unit amp. Transformed my audio so much I will be ordering another for my truck. Sound is clear, install was a breeze, plenty of power, and it fit behind the dash for a simple, install. The quality of the housing and sound was better than expected especially for the low price.
