I have a sound digital 400 amp on a 2012 street glide. It just randomly stops. Well I’m assuming it’s the amp. The head unit is a AV aquatic. Still displays the track is playing but no sound. Turn the bike off turn it right back on and everything works fine. It may play for hours on without a problem or it may only play 5 mins. Plz help and thanx in advance. I replaced the rear speakers from 5x7 to 6x9 went with the pioneer TS6900 pro. And I’m thinking that’s about the time this started.

 

I'd say start by checking the speaker wires make sure they aren't loose. Then check the power and ground and make sure they are secure.

 

will do thanx. If by chance I crossed up the pos and neg could that cause it. Maybe sending the amp into protection mode.

 

It will shut down if the gains are too high also.
