I just finished installing a sub/amp in my factory '12 SEL and was able to hook up through the factory radio with an adaptor from ebay and made the install a piece of cake. So no need to tap in the door speaker harness, see attachment
Hey, Mo here! New to the forum but not to the car world. I’m a former 15 year Ford senior master tech with a local Ford dealer. I currently own a 2020 Ford Edge ST, 2014 Ford F150 FX2 and my daily 2012 Ford Edge SEL. The ST is the newest addition and modded with a AFe CAI, Turbosmart BOV and 20” M-Tuned black wheels. The daily Edge only has 20” black Enkei wheels. Looking forward to learning and contributing to the forum!
