Ok, i just purchased a head unit for my car. Its a sony L550X. All the wiring and everything is as it should be however there is a large black plug with 5 connectors in it. I had the stock CD player, stock casette player, and regular AM/FM radio with the listening position thingamabob. What do I do with the black thing? Im comtemplating ripping all stock amps and crap out and just installing my own equipment.

check tech questions postr in one spot that way people who never check here can keep the same thread going

Start over. Rip it all out. It's easier!
