anyone ever hooked up a head unit for a 2001 toyota avalon? From everything ive read, i have to bypass an external amp behind the glovebox which sounds like a major pain in the ass. Do u think it would be better for me just to take it to a shop and have them do all that mess? It seems like ill have to run new wires from the head unit to the speakers and whatnot and im not really up for that task. Any insight would be appreciated
