Beretta.net

I just recently obtained a BOSS AVA-1404 and was planning to bypass the stock head unit and use it directly with my MP3 player. Was looking at what I needed to di when it dawned on me I have absolutely no clue what the wiring colors are in my car. I have a '90 Beretta Indy. If anyone could help me out it'd be greatly appreciated.

so are you going to buy a cd player for it then?

wasn't gonna unless i needed to. from my understanding i should be able to directly line in my MP3 player. but i've got a head unit if need be
