Hi guys, I have a 2011 328i base model. I upgraded all speakers in the car except the underseats. I also installed an amp for the speakers. For some reason the sound on the front passenger side always loses sound in the morning and then would come back after like 10 minutes or so or until I start the car again in the afternoon.

I am still using the factory headunit. I changed out to a new battery since my old one was dying and I thought maybe the battery was the issue but the speakers still cut out. Could a faulty headunit cause this? I bought the car used and everything was stock when I got it.

Any ideas?

Did you split the parallel connection between the front doors and floors?

Who has step would that be from the link? Is that the jumper part you mentioned with the underseats?
