So I installed my jbl club 5501 to push my skar 12s in my 2013 Avalon. I tapped into the rear deck speakers and ran everything from a line output converter, but I believe that because I tapped in after the factory amp that it’s pulling power from both amps consecutively; at times it’s extremely loud, but just doesn’t sound right, not sure what to do.

If the speakers are not in phase with each other, there can result some soundwave cancellation.
