1987 Corvette Bose Audio system HELP!!!!

Also here is a pic of the head I am wanting to replace the bose with. It is an alpine flip out dvd single din. It comes with the brain box, and an ipod hookup box.

I am having some major problems trying to hook this up, not only because I dont know what I am doing, but also because when I talked to some techs at a stereo place, they were telling me how the bose amp that is hidden in the car does not let you replace the head with a non-bose product. I have heard there are ways to bypass this though.
If someone could walk me through how to hook this up, I would love to pay you via paypal. A local stereo shop quoted me 250 dollars for installation alone. ABC Warehouse had a junior tech look at it and he quoted me a little cheaper, but was saying he would replace some of the speakers for better sound quality.
Please guys, help me out!!!!
I also posted this is in the c4 section so, in case it looks familiar....
