I have the same problem. I have 2 alpine R 6.5 components in the front and 2 alpine R 6x9 in the back. 1 alpine type S 10 inch sub. If I turn the volume up it shuts off the sound. I shut my deck off turn it on again and it works until I crank it up again, then it's the same problem. It's not too hot because it will do it right when I start the vehicle if the volume gets turned up. If I disconnect the sub I have no problem. I've tried 2 different subs, same issue.
