In my superduty I have a Alpine IVA-W200 headunit.
Pretty straight forward, 4 speakers off headunit, 1 sub wired from "sub" output on the back of the deck.
I am having 2 issues, don't know if they are related or not
1) memory for head unit (presets, crossover controls, DVD memory, clock etc) completely flashes when the key turns off
2) Occasionally I get a humming noise from the subwoofer, it is not consistent, not alternator whine because it was doing this while the truck was not running, and not related to the level of volume.
I hooked a meter on the yellow memory wire at the harness and found that ample power is being delivered. I don't know if there is any other places I need to test because the monitor has wires for brake pedals and when it was installed I had them wire it to an aux switch. Also there is no fuse on the back of the deck like I have seen on some decks.
Thanks, radio's aren't exactly my specialty.
