I am wondering which speaker I should get. They all seem nice and I would need two 6.5" and two 6x9. I was looking at the Polk MM652, MM692 (without headphones), Infinity kappa 60.11CS, 693.11I, JBL Stadium GTO620, GT0930, or the JBL GTO609C, GTO939. I think getting the JBL GTO609C and GTO939 would be the best bet because it is almost the same as the JBL Stadium GTO620 and GT0930 but $130 cheaper and components for the 6.5". What is your guys opinion on the speakers listed or other ones in a similar price range? What should I get?
