Hi, i wanna hook up a amp in my car and was wondering where i can find a accessory wire in the dash that i can use to run to the trunk. Is there a way to do this without opening up the front dash? If not, then where would be the easiest place if i did have to open the dash? I didn't wanna open up to many things since the wiring at the back of the dash also controls the onstar and the airbag. Any suggestions?
