Does anyone know what model bose amp is in the car, and also does anyone have a wiring diagram for the audio systems. I bough an aftermarket indash dvd, and I will need to hardwire it. The only thing is that this audio install shop told me that I would have to go directly to the speakers and would have to bypass the amp. I am thinkg if i had a wiring diagram i could figure out how to hook it all up. If anyone has other ideas please let me know. thank you
