03 Z71 premiume bose diagram?

 Hi all,

 I`m looking for the wiring code for this truck from the bose amp output.I need the color code for the speakers including the factory sub.My friend does not want to 9vPOP the speakers for some reason,even though he is replacing all of them.He wants to keep the factory head unit,so he must keep the bose amp for fade control,plus he want`s to use the the factory wiring(dont ask me why, I`ve warned him against this).Everything behind the bose amp is being replaced,so any help you guy`s could give would be great.

Thanks                                                                                                                                                                                                   Ratwerkz

       Just an fyi, BOSE speakers are 1ohm speakers. The majority of aftermarket speakers are 4ohm. Unless you are planning on replacing these speakers with aftermarket 1ohm speakers (I have yet to find these) the truck will not sound very good. It will either be distorted or not nearly as loud as before. This goes back to ohms law V=IR, voltage stays the same but you increase the resistance on the bose amp outputs then the current coming out of the bose amp will go down proportinately(sp) to the resistance going up. Since watts=VI, the watts to your 4ohm speakers will be alot less than the watts that were going to the 1ohm bose speakers, ultimately losing clarity/volume. 

      Basically my suggestion for you friend if he wants to keep the stock bose deck is to buy an aftermarket 4 channel amp and some line level converters. Hook up the line level converters to the outputs coming out of the stock deck or if you cant find them there out of the stock amp and this will give you RCA outputs (make sure you get line level converters with adjustable outputs). Then you can hook up the aftermarket 4channel amp and speakers as you normally would with a aftermarket deck. BOSE stuff is not fun to work with in terms of adding aftermarket stuff to it. In my shop its an all or nothing deal when it comes to bose stuff, we just replace everything with aftermarket stuff and run new speakers lines.

Good luck
