Help needed on purchase in central ontario
 

I am looking at two options so far 1. Alpine cde235bt with JL 6x9 in front doors and JL 6 1/2 in rear doors 2. Clarion CX650 infinity reference series 6x9 in front doors and infinity ref. 6 1/2 in rear doors I am installing this in a 2014 GMC Sierra double door pick up. The alpine set up is $180 less expensive than the clarion set-up. Any ideas? Should I forget the rear speakers and go with an amp for the front 6x9's instead. The alpine is from fast forward in Midland and the Clarion is from Tom's in Barrie this will be installed by where I buy it

I would go for Option 1 and, forget the rear speakers, and spend the extra on a better series of front speakers and an amp for them.
