I have a alpine 5 channel amp hooked up to components up front and coax in the rears.
I took the car into an audio shop to get an estimate on how much it would be for a sub and new Head unit and the guy did some amp adjustments and turned the volume very high while doing so. He said he fixed some adjustments.
Anyways on the way home I noticed the speakers would sort of get staticy once in a while but it wasn't too bad. It only happened on the right speakers. The left are fine.
I went back a week later and he made some more adjustments and the problem got even worse and sometimes the right speakers would totally cut out. he said the amp was bad because the problem got a LOT worse (you could hear tons of static) while he was turning the screw for the gain (or volume) on the amp. He also thought the front speakers were hooked up to channel 1/3 and the rears 2/4 which he said shouldn't be a problem but is strange and would explain why the rights were cutting out like that.
He told me to get a new amp.
So I'm wondering. Could he have done something to cause this problem? I mean it seems like he did but he said that it probably happened because the amp is 4 years old and the screws need to be turned every once in a while or they may cause problems. Does this sound logical?
Also, can I fix a problem like this or should I just get a new amp? He also said that the 5th channel may not even work since it hasn't been used for 4 years.
