I have a kenwood excelon 579 deck, and yesterday while driving it started smoking when i had it on a moderate - loud volume ( maybe 60% volume). I promptly turned it off, but now when I have it on a high pitched noise comes out of the speakers, even when the deck is in standby mode (i.e. shouldn't be sending any signals). Messing around with it further, the noise only is apparent when my headlights are turned ON. Everything on the HU seems to be working correctly though.
What do you think the problem is? A blown fuse? Is this something I will be able to fix, or will I have to get a new deck.
Thanks a bunch,
