03 Z71 Tahoe with Bose: Help!

I just do not want to eat up any space in the back with an extra enclosure and I do not wnat to tempt any shady characters.

Thanks for the info.  I just want to make sure I understand everything.......

I need to buy the c2a-GM24 OR the SMI-15.  Then remove the cupholder to access the Bose amp.  Which one is the Bose amp?  I am guessing it is the only one with a blue clip.  The TR-4 is just to allow me to hook up the remote wire right?

That's it?  If so that is very cool!

Thanks again!!!

Yup, and either or thing.  But the C2A isn't available yet, so unless you want to wait, go with the SMI-15 and TR-4.  The SMI gives you an RCA connection, the TR-4 a remote wire.  Really easy installation.  The Bose amp is the only one under the storage box in the center console.  You will need to remove it to get to the harness plugs.
