Right i have never had this problem before and I wanted to know if someone could help as I have had a crack at solving but haven't had any luck.
So I've got a 5 door mk4 astra and as you know it's got speakers and tweeters on each door. I got a set of 6x9's on the parcel shelf pioneer and sound was working great and no problems. Now recently I've fitted some pioneer door speakers in the front. Now here's the problem.. I'm listening to music quite loud as I like it and 15 mins down the road the sound cuts out even though the radio works.. What could it be? Checked wiring nothing wrong can't find any breaks or shorting out. What I also noticed is that I traveled for about 2 hours with radio on just not as loud as usual quite quiet and sound didn't cut out.. Could it be that the power from all the speakers is too much for the radio that it goes to some sort of safety mode and cuts the sound? Cause I've noticed it gets really hot and if I leave it for a good few hours and try again the sound works.
Any help would be appreciated!!
