Not a lot of spaces behind a civic. I might try redoing all my grounds including the amps to see if there's any successTry moving the rca's to a different location. Many head units put out a lot of noise as well...
Switching the rca's out may also help.
I believe that's only for the Pioneer heads due to the pico fuse issue. Funny thing is I didn't have engine whine with my Pioneer, it's when I switched to this Alpine that it's doing it.I've also seen people ground their RCAs behind the HU and have reported relative success with that.
I don't have interference as much as engine noise. Whines like a mofo and loud as hellwhat would the noise be sounding like? I don't think I've ever heard RCA interference.
