Did u install your sound system yourself? If u did, where did you ground your amps? I tired of getting that whiny noise. Also, do you know which one is the - and which one is the + for the dome light tweeters?

Thx.

 

I grounded my amps to the seat belt bolt under the back seat. I also sanded the painted area where the bolt goes in with some sandpaper. That whining noise might be your RCA cables if they’re
close to power wires. I routed mine straight under the passenger seat away from power wires. I didnt even bother to use those dome tweeters. I mounted Focal tweeters in the sail panels. Thats
all you need.
