I had a Memphis 16-PR1.500.1 given to me a few days ago.I was told it was cutting in and out,so I hooked it up 4 days ago.The first 2 days no issues,went out yesterday started my car no output from the amp.I pop the trunk amp is on fan running,not in protect then out of nowhere it starts playing.May play two days may play 5 minutes,then it stops again,so I hit it with my hand it instantly goes back to playing! So I'm thinking something has gotten loose on the internals somewhere.Was curious as to what some of you thought about it.
