[QUOTE="JustinStone, post: 8773039, member: 680824"] I've isolated my alternator whine to two components: RCA's or Headunit. After ensuring a good ground on the amp, unplugging RCA's at the amp, and relocating the HU ground to a metal behind the radio I'm still getting pretty obnoxious whine. Here's some things I've noticed: - gets higher in pitch with rpm - gets quieter when volume is 0 - very quiet when radio is off - almost inaudible when in "standby" source - only noticed the whine after installing rockford 600.4 - when using 3.5mm jack, tone can change pitch based on where the cable is sitting in the car with no phone attached - whine is present on all sources except standby - the whine gets intensely loud when charging phone and using aux (ground loop whine??) - when charger and aux are in, the loudness of the whine increases with headunit volume - probably unrelated, but my alternator does produce a high pitched sound itself from the bay, the whine inside the car sounds very similar in pitch. any ideas on how to either fix it completely, or at least knock it down from making my tweeters play 5 watts all the dang time thank you [/QUOTE]
