    If you have Bose then all 4 speakers are amplified, if you don't have Bose then the rear speakers are amplified and the fronts are driven by the head unit.

    There are some aftermarket adapter leads available to buy. Do a google search or search this forum.

    audio car ted seems to be a decent website. pop in your car and what head unit you are changing from and which one you're going to. brings up all the cables you should need. worked when i did mine!

    i changed from concert II non bose to an alpine head unit

    I got the iso harness but the wires aren't in the same place as the concert 2 and the wires from the harness arent in the same place as the pioneer. God this is frustrating . How hard can it be?
