I am trying to figure out if the amp in the 05 6 cd bose system with onstar without navigation is seperate from the head unit or ikintergrated. Is it low level or high level?

I bought a used Metra VT-GMOS-04 GM Class II Data bus Interface and it is already setup for a low level amp and I want to know if I am going to need to rewire the harnesss before trying to install my aftermarket head unit.

I believe the Bose amp is located behind the glovebox...
All bose amps are in the console.
Under the storage box between the seats, In order to get to it both front seats must and the console must be taken almost a completely apart a real pain in the a$$

I did it before a couple of times

Here is a how to link
