it started this morning, i'm starting to hear an induced variable engine whine coming from the drivers. this has never happened before until today, i checked all my connections and everything seems fine. nothings crossed or anything.

anyone have any idea's what could be causing it.

everything is grounded to the batteries, and all connections are soldered ground correctly

check the grounds, everywhere.

behind the deck, ground the chassis of the deck to the chasiss of the car, so on ext, ext..

alls check the ground for the amps/ batt's, grounds can go bad after awhile so check over everything.
