I purchased a factory sub that came out of a 2013 Ford F-150. I want to put it in my 2009 Ford F-150. It also has the system with the factory subwoofer, however, the sub was missing when I purchased the vehicle. The sub fits perfectly under the seat and lines up with holes for mounting. The harnesses are different though. Is there a way I can wire that sub into my 2009? Any help is appreciated!!
