## Customer Reviews

### ⭐ Blew my speaker on powering on !
*by M***L on May 19, 2024*

I bought this to power 2 4.5" and 2 6.5" alpines but after connecting I smelled burning electrical. After investigation I found it blew one of my alpine 6.5" 2 way speakers so I can't use this piece of junk. And I really liked those alpines too smh. It must have a shorted output or something to send full voltage and cause this to happen.
