I'm sorry if this has already been discussed, but I cant find it anywhere on here. I am leasing a 2011 fusion SE with Sync, and don't want to do anything too intrusive on the car, or screw it up trying to take apart the dash. I know how to wire an amp, but I am curious how I go about tapping into the speaker wires from the head unit. Do I have to remove trim on the dash and pull the factory stereo unit out? Or, is there a way to get to the wires somewhere else? I intend on using a line level to RCA converter. Thanks for any help!!
