I recently bought a US Acoustic amp and was trying to mount it. Pre mount, everything was in working condition. After mount, amp powers on but no sound in front speakers and my sub. I unmounted it, and same problem. I then connected another amp too my front speakers and voila sound in front. Tried another connection with the US Acoustic, and no sound again.

What do you think has happened? Do you think all the movement might have knocked something loose?

 

if i like the amp i would send it out
if you just think it is ok them openen it up to see if you can fix it

 

If you're in GTA, you may drop by and we can check your amplifier for free. Thats' right, we offer free estimates.
