hey i have an 07 new body style silverado 1500 ltz with bose sound system. installed a rough country leveling kit. im more of a mechanical guy. i have a question i am looking at adding an amp for a subwoofer and i have no clue as to how to get the stereo out of the car and get at the wires for the system. i was wondering if anyone has done this and had some pictures and info on how to do this. i want to keep the stock head unit to keep the steering wheel controls. if someone can help me with this that would be great.
