I believe the 9 speaker system is one in each door, two in the dash, two in the cargo area (Not exactly sure where these are located), and one sub. That's 9 total. The Summit should add a center channel for 9 speakers, double that for using 2 way speakers, then add the sub for 19. In all reality, all you are getting is a little higher quality speaker (not much really) and an additional speaker in the center of the dash. I could be slightly off on speaker placement since I don't actually have my Jeep yet, but you get the idea.
They could have (And should have) called the Summit's stereo a 10 speaker system, because that's really what it is. It's like me replacing all the speakers in my Overland with 3-way speakers and calling it a 25 speaker stereo. It's all marketing...
They did the same thing in my 2012 Ram with the amplified Alpine stereo, which honestly didn't sound as good as the base 6 speaker system I had in my 2010. I've completely gutted the factory stereo and replaced with "Real" Alpine speakers and amps. Now it's actually worthy of the Alpine logo on the dash.
