I've been using JBL amps for about 7 years now. I had a problem like this with a bp600.1. I switched head units in my wifes car, after I did that the went in to protect all the time. I figured out that it was because of voltage drop, so I rewired the amp and the problem went away. I have a p80.4 in my scion xb in the storage bin underneath the false floor in the hatch and I have never had problem with it, of course I don't turn my volume up all the way up either. Did you try and fix the problem before you called them. Rather then just thinking that your right about the problem why don't you take peoples suggestions and go try to lower the gains and see what happens. It couldn't hurt to try and fix the problem yourself.
