LC7i install and factory harnessI am about to install a LC7i on my 2017 dodge charger with beats audio and i removed the dash and found the factory amp. I need help in figuring out what part of the harness to splice into. I felt under and found where the wires go into the amp but don't know where they come out. I did see a harness directly in front of me when i opened it that had a connector piece that looked like all the speaker wires and i think that is it but want to make sure. Any help is greatly appreciated!!
