you could still splice into the line out of the head. you'd have to do 2 pairs for fronts and rears.
then you could just switch the head on and control volume with the zune.
sorry it's not working out man...
i understand the stock vibe, really, but an aftermarket head doesn't have to stand out ya know...
the PO had put a silver head in there (wired it bad too), now that was really ugly
