    Replacing BOSE system '94 STS

    Hi all, i own a '94 Seville STS and want to replace the compelte BOSE system. I am not going to try and tap into it, just bypass it. I need to run new wire. What is the best means of running new wire to an aftermarket head unit to aftermarket speakers??? i want to do this custom job myself and am a little confused about running the wire? do i just speaker wire from teh BOSE speakers with the new wire that leads into the BOSE headunit? or simply, rewire the wire-harness for the new wiring??? DO i need to leave the BOSE system in existence? i've heard i should leave the headunit connected and leave it in the back trunk? what do i do with the amp in teh back? i will not be running a seperate amp, just the amp on the headunit. do i disconect the stock amp?

    Basically im really confused here and want to get this all straightened out. Im replacing my BOSE system completely and want to bypass it? I want to do the whole job myself to save money. How do i go about doing this?? thanks all for the help.

    This is the route i took on my car with the Bose system.
    I removed the factory head unit, stereo, all the factory speakers. I bought a Dash kit to mount my aftermarket head unit (stereo). I installed my new aftermarket speakers and ran all new speaker wire from my new deck to them.

    Here is a link to a site that will show you with pics how to remove your old setup > just type in the make/year of your car and go from there.

    I would just remove the head unit (up front) and all the speakers and run new wires from your aftermarket deck to the new aftermarket speakers. You will loose your door chimes,daytime running lights and steering wheel controls, without using a "Interface" designed to bypass the Bose system.

    I am an mecp certified car audio tech. So its a little easier. I ran all new wires, constant, acc, ground and solid blue from the tuner on the right of the trunk under the power antenna. Also ran new speaker wire all the way around. But technically you don't have to do that. Its a little more time consuming but u could go to each speaker and connect each negative and positive before the amp, this is bypassing at each speaker. The next thing to do would b to ground to the chasis. The stock ground may not be enough for the new stereo. If you have a main amp in the trunk u must test for input and output, sound input wires from old stock stereo and sound output from amp. You need to connoct the input into the output. And that should sound great.
