Ok I have a 2000 chevy blazer 4 door trailblazer package with a bose factory in it. Im wondering where the bose amplifier is. Is it under the center console or behind the glove box? and how big is it. Also I went to replace my front door components with 3 ways which were the called for 6.5 inch and they are too small and deep to fit? Any available adapters or easy fixes? Thanks just trying to redefine my audio and make it simple.
