**** bro that *****. I have had my 3kwp for about a month and a half now, got it in a trade an had the power supply repaired well in this 2 mo th time of owning it I have listened to it maybe 8 times. Well last Sunday it was working and I parked my jeep cause I was having surgery on Monday.
Well I go out yesterday now mind you it was working all this time an I just been listening to deathcore no rap or any heavy bass stuff just metal an I go to start the jeep an low and behold this mug is in protect I checked my grounds an everything just like you did and everything checked good
Well tonight my cousin was driving me to the guitar store cause I needed strings an this thing was playing just fine. So it's like it decides to work an not work when it wants an it's pissing me off. So I feel you on this man it ***** an I bet mine is heading down just like yours an is gonna need repaired again.
