2011 chevrolet tahoe

hello. i just bought a 2011 tahoe. would you possibly have the wiring diagram for it? i dont know if its the same for the 2008 that i have found onlne..i want to keep my factory stereo but want to install an aftermarket amp. these newer vehicles are getting more complicated. sometimes you can use a LOC and i had a 2010 charger i had to buy a $150 part to use aftermarket amp. whatever advice you can give me is appreciated.

i have onstar but i dont believe i have bose since it does not say it on my msrp sticker or anywhere on the vehicle. thanks buddy for the help.also if you may know id accept any advice on a good amp speaker set. im thinking probably 2 12s and and amp that hits hard =) ..any advice on best place to install LOC on this is appreciated as well.  thanks for your reply

Should be the same as the 08.  Best place is going to be behind the radio.  That way if you ever have to change out the radio, the RCA cables will already be there.

thx buddymp
