Default New Car!

Helllo all, I am a proud new owner of a 2000 SSEi. Bought the car this weekend and so far I love it. One thing I am still getting used to is the factory Bose System in it. I had a pretty nice system in my last car and this one is just not up to my standards. So, I come to you with help replacing it. Right now, all I see myself doing is replacing the factory HU and adding the sub and amp from my previous system. I have never dealt with a Bose System or any GM car before so I am looking for a little help. I've looked online alot at wiring harnesses and still am lost on what I will need. I want to keep all the chimes and hopefully all the functions associated with the factory HU (steering wheel controls, etc.) What harness do I need? Any help would be much appreciated.

I suggest keeping the factory head unit and replacing the factory amp with your amp and subs. This will keep the RAP, chimes etc. and you will still have an unblemished dash. You may want to replace the speakers though, because the speakers for the Bose system are 2 ohms, I believe.

The biggest problem with factory systems is the power output and the speakers. Because the Bose system is "characterized" to the car, you may also want to add some equalization to be able to "tune" the response curve to the car, amp, and speakers.

This is essentially what I am doing. Since I have an SE, it didn't come with the Bose system and subsequently didn't have a separate amp. I have purchased a Bose system head unit and am in the process of getting everything together to do what I said above.

Oh, BTW, WELCOME!!!

Ok, would it be better to use a line output converter for the sub amp and just splice into the rear speaker wires? I think replacing the Bose amp entirely would mean I would have to replace all the speakers in the car, since the crossovers are built into the amp. I wouldn't mind keeping the Bose amp and speakers provided the sub doesn't overpower them.

The wires going INTO the Bose amp are already line level so you can splice into them (thus avoiding the hit in sound quality of the converter).

The amp should be behind the rear seat (in the trunk).

The wiring diagram I have (for a 2001) gives the following:

LF input (+) = TAN
LF input (-) = DK GRN

LR input (+) = BRN/WHT
LR input (-) = BRN

RR input (+) = DK BLU
RR input (-) = BLK

RF input (+) = LT GRN/BLK
RF input (-) = LT GRN

So, just to make things clear, for the sub amp, I would splice into the rear speakers just before the factory amp and run the wire to the speaker inputs on my sub amp? If so, does this eliminate the need for RCA cables? Also, where would I connect the remote wire for my new amp?

Yes.

I am unfamiliar with sub amps. It may be that the sub amp'* line level inputs are RCA. If they are, you will need cabling with RCA on one end and splice into the factory amp inputs on the other. If your amp has another kind of connection, you can use that.

You can use the same wire as the factory amp, it is a pink wire. It shows it may be in a different connector than the speaker inputs.
