I've been in conversation with Kicker and have learned just today that the Shelby/Kicker amp only powers the four 6x8s and not the door subs. Rather, that Shelby amp is a 4+1 with that +1 being an output for a trunk sub. At least in my 2013 premium, the OEM door subs, even if you install the Shelby/kicker amp, remain powered by the factory amp. I'm working with Kicker right now to identify the best way to add some thump to the Shelby/Kicker door subs that I installed. Trying to avoid installing trunk sub.
It's funny you say that. The same day I posted this I found out the same thing about the Kicker amp. I would have been pretty pissed if I had spent the money and then found out. I'm looking forward to hearing what the guys at Kicker have to say.
