You would need:
1) Bose Head Unit (replaces your non-bose head unit)
2) Bose Amp (installs under passenger seat)
3) Bose speakers (2 3/4" tweeters, 2 6.5" speakers, 2 5.25" speakers)
4) Bose subwoofer + amp
Then you will have to wire everything by hand since your car doesn't have the same wiring harnesses. Good luck. For the trouble, you're better off just buying aftermarket gear.
