The shop that is going to install my system told me that since stock bose speakers are 3 ohm, if i run them off of the built in head unit amp and disable the stock bose amp in the car, it will screw the head unit or the speakers up since the head unit is not made to run off of 3 ohms (the reason i need to do this, is i am amping my new components in the front, but i want to keep the rear bose speakers for rear fill). He was saying they might be able to still run the stock bose amp with all my aftermarket stuff, but they are not sure. Any ideas of a way to tell them to get this to work? I guess i could only run my components, but that would be kind of stupid since this is a large SUV.
