i went to circut city and a couple of local sterio shops and i was lookin at puttin in a flip out dvd player a jl component set and a sub. they told me since i have the bose system in my car that if i changed the head unit that i would have to rewire the whole car! has anyone else had this problem its a 01 ssei

yes, you will have to do some rewiring to bypass the stock amplifier.

That'* a little extreme to say you'll need to rewire your entire car. You won't. If you replace the factory head unit, you'll also need to replace the factory speakers, and you will need to run new speaker wires. None of this is difficult, stereo installation shops literally do it every day for a living, and you can do it yourself if you have some spare time.

Frankly, there'* nothing sacred about the factory Bose system, you can certainly do *much* better for sound. However, some things to consider are: The factory Bose system integrates with the heads-up display if you have it, so you'll lose the radio information display if you go aftermarket. Also, if you use GM'* built-in OnStar, it uses the factory radio and speakers for the output of OnStar communications. And finally, if you have steering-wheel controls for your stereo, you will lose that functionality unless you also install an adapter that converts the steering wheel controls into Infra-Red remote signals, -if your aftermarket head-unit supports a remote.

If you were going to lose steering wheel control functionality, I suppose another option would be to replace your steering wheel with one that didn't come with steering wheel controls, for a nice appearance without the disgrace of disfunctional steering wheel controls.

Personally, I wouldn't hesitate to rip out a Bose system.

I have a aftermarket HU and subs in mine.....needed a special adapter to use the Bose setup......run the subs thru the headunit and amp....while the rest of the speakers run off the factory.....I believe it is a GMOS-09 adapter.....costs about $100. This allows you to keep the chimes and Onstar.

That sounds more like it, I have never heard of someone telling you that you need to rewire you entire car because of a head unit. Thats why they make Wire Harnesses, They were trying to get some money out of you.

good information, i agree. I would just get the harness and a nice componet set and diy .
