Corps 'Vette

Need a Bose sub and a dash tweeter for 2013 (other connectors wont fit for sub) OR if anyone has better advise and the parts to back it up (like a full suite of replacements and an amp) I'll entertain that idea. Bonus round, if I find the bose sub and tweeter cheap enough I'll be looking for a new head unit if anyone's selling one (3rd party; I'm looking to remove my GM nav unit).

I have a Bose dash tweeter from an 07 if that will work.
