If you mean aftermarket amp, then no. I didnt do the installation so I dont know if they did anything with the factory amp or if there even is one in the truck. I have not had a chance to even check to see if its a loose connection behind the deck. All I have is a deck and cd changer. I was hoping for a starting point like where to check if it is a wiring problem. Or if it could be my alternator is going out....any help at all would be appreciated.
