Need help Removing Bose System, 1995 STS

 I just recently revieced a two subs, two amps - one for the speakers and one for the subs, and a new cd/dvd player. I wanted to have it installed, however I was told it would cost about $500. Instead I have been learning as much as possible about the installation, however though I still dont know exactly what I have to take out in order to connect my system. Any help would be much appreciated.

Removing old stuff is not hard. Your focus should be on what you want to add.
