Audio Systems: Bose 6 disc, auxiliary input adapter, rca jacks

Question
I have a Bose 6 disc system in my 05 GMC Envoy with ONSTAR and steering wheel control and want to add an amp and speakers, perhaps a sub with and another amp, if possible other items ie a flash drive to the system what do I need to by for modules or etc.
Thank you.

Answer
All of that is posibble  
this is the module for the amplifier you will get two rca jacks the audio comes  from the bose amplifier data and it will also give you the remote 12 volt to turn on the aftermarquet amplifier

this is the auxiliary audio input, can be use for ipod mp3 or any other audio source

and this is the usb interface  the only small problem is that you have to use a remote control
amd it is fm
