I have an aftermarket Custom Auto Sound USA 630 and a 100 Watt per channel Alpine amp. There's 6 JBL speakers. Four in the original locations in the dash and next to the rear seat. I custom installed 2 in the front door panels about 4 years ago.
The speakers in the door panels have new speaker wire run to them. The 4 in the stock locations still use the original engine harness speaker wires. last year this wasn't happening but when I took the car out at the beginning of this spring there was a whiny engine noise in the rear passenger side speaker.
I was thinking the original wires in the engine harness are thin. I want to run new speaker wire to the 2 rear speakers and the two in the dash.
