tweeter whine..

[Daishi 10+ year member]

i cant for the life of me get rid of the whine coming out of the tweeters.. fyi i dont have the car started this is with the ignition on acc..

i have everything in my trunk grounded to the same spot to avoid ground loops they are grounded to 1 of the seat bolts i sanded down the paint and i checked the resistance and it was 0 resistance which is a perfect ground..

rcas are not run on the same side as the power lines they are run on the opposite side. there is no power line within atleast 1.5 feet of the rcas.

ive tried several grounds on my pioneer 880 head unit. tried chassis ground and stock ground i even tried connecting them both together still no go.

i tried grounding the rcas and no go.. any ideas? im about to throw my car in a ditch...

i also heard sometimes the antenna can cause the whine due to the ground on it.. disconnected the antenna no go...

if you have a mp3 player try hooking that up stright to the amp. see if it goes away

ALSO i just found out that if i unplug the rcas for my amps that power my subs the whine goes away.. if i disconnect the remote line to my subs so the amps dont power on i dont get the whine either.
