I Have a 2003 Touring Z with Bose and Nav. I already have http://www.crutchfield.com/p_037A800...T&ssi=0&tp=115 and http://www.crutchfield.com/p_113W251...+10+subs&ssi=0 installed running off the stock headunit. I purchased http://www.crutchfield.com/p_1086022...2i&ssi=0&tp=95 for the doors and http://www.crutchfield.com/p_130AVHP...p3100dvd&ssi=0 for the headunit. I haven't bought speakers for the rear yet because everyone says you dont need them. The amp and subs were installed by BestBuy, so I have no idea how theyre wired to the headunit. Basically what do I need to do to get rid of all my Bose, and does anybody have a walkthrough for a Z with Bose and Nav since this will be my first install. And what will all of the tools and other goodies will I need to install this.

I also would like to do a parking break bypass switch, so if I could get some info on that too that would be great.

 

Won't be negative here - BUT - the sticky threads in the audio visual section has everything you need. I've learned everything I need to put in a top system in my Z. BTW - ALL the stock stuff is junk as far as I'm concerned and needs to be replaced. IMHO

Get yourself a factory service manual with wiring diagram. Very helpful. Free on the internets.

Appears that the only Bose component you have remaining is the woofer amplifier. Don't know if it is driving the woofer.
