just bought a 2000 eldorado esc, which has a stock stereo but the eldorado etc has a bose system with amps on the speakers, want to know can i switchout and put the bose system in without changing the the harness to the stereo and the wireing to the speakers, my mechanic said there might be a possibility that when my car came off the assembley line they wire it for both stock and the bose system and leave the wireing there that is not used, that would make switchout easy and practical, i can get the bose system at a fair price on ebay and if the wireing is there then i would do it, plus i want to keep the car the stock so that bose system was made for that car, it was pulled from a 2000 eldorado etc, thanks grock
