my 2002 came with a infinity sound system. The deck sucks and I want to put in an aftermarket. What do I need to buy to accomplish this?

 

Got to Crutchfield and pick out a new deck and then get the installation kit to go with it. You can enter the specific vehicle and have it only show you units that will work.

 

really funny! Everybody made a big deal about hooking up to the stock infinity system. It was simple, match up all the wire colors. The only thing that was awkward if you had to hook up the amp into the power antenna.
