    97 STS Seville Audio Upgrade

    Just want to say sorry for starting another thread on this topic, I have read endlessly but still am unsure what to do.

    In my first thread I learned that there is no way to install a new head unit in my 97 unless I rewire the car, which I am not ready to do at this time.

    However I am still unsatisfied with my audio setup. I would like to have some more bass, but unsure how the easiest way to add some subs to my current Bose system.

    Also, I read that you can put a in dash CD player if its Bose anywhere from 98-01? Which models work? And how do I know the Cadillac dealer will unlock it for me?

    If I choose to rewire my car, I honestly only want two highs (1 in each front door) with a highs amp and a pioneer head unit. Is this an all day job with the Cadillac to rewire the two front doors? If I rewire do I need the GMOS-06?

    Are there any other options I may be looking over here? Thanks!!

    dealer will have to go under 1998 year to clear the theftlock

    rewire youll need the gmos-03, it keeps the comp happy and gives you the ignition, ground and constant power wires, then you run new speaker wire from the hu to the speakers do not use the bose speaks powerd off an aftermarket deck
