Do i have a factory amp? I have a 2009 6 disc, non-Infinity, 7 speaker system. I just ordered the 77kick10 speakers to go in prior to my or-fab cage. Figured while i was digging that deep it might be a good time to upgrade to the Dodge Nitro amp fix i hear so much about. I think the Infinity amp hides below the steering column so that would be an easy switch. But does the non-Infinity 6 disc sysem have an amp too, and if so, where does it hide?
