Wsup yall

I'm facing a bit of dilemma on bose system. I have '03 with stock non-bose system. I'm trying to buy all bose components (speakers, tweeters, sub, amp, rack, headunit) and see if they can be replace my stock audio components with them.

If I decide to buy '05 or '06 Bose headunit, will that fit into my '03 and install with no problem if I take it to the stereo shop? Other Bose components are from different year Z (I believe '03-'05).

If yall can drop some knowledge in details...I'd really appreciate it.


Thanks!
