I have a 1996 ford explorer with a stock deck in it. There have been no modifications to it, but i need to make some of my own. I have a US Acoustics amp. It is an 80W x 4 Channel. I need to find how i should wire it into the factory deck that is in there. i took it out and looked at it this morning and it is nothing like my last car i wired into. does anyone have any photos or pointers to give me so that i can successfully wire this in? i also need to know if there is anything ill have to purchse to make it work.
