Hello, I have a 1998 ford f150 3 door(with the auto button on the factor stero, if that helps any), and im putting in a new stero, speakers, a amp, and a 10" sub. and i was wondering if my truck has a factory amp, because im am putting a amp for my sub. What im asking is like, what if it does have a amp, could i like make my truck use both, the factory one for whatever it was put there for, and the aftermarket one im putting in for my subwoofer.
Thanks Help Me Out Please
