### ⭐⭐⭐⭐⭐ Wow! Impressive!
*by T***V on December 4, 2025*

Very impressive sound out of such a small package. About the size of my palm. Watts will very dependent on your setup and speaker ohm rating. If you have never delt with Brazilian amps? Setup is a bit different having 6 ports for 4 channels. Do a little research on YouTube. They might not have this brand specifically, but search Brazilian 4 channel for tutorials.
