Here is a C2-600 set up for $149 w/free shipping



JL AUDIO C2-600 +2YR WRNTY 6" 200W CAR AUDIO STEREO COMPONENT SPEAKER SYSTEM

Since I only got a pair of C2-600CW woofers, I'm thinking going with the budget Dayton Audio in 4 Ohm to match the front door JL with the 0.75" tweeters in the rear doors like Prop did.

Edit: Thanks RB I just ordered the Dayton Audio for my rear doors from the link you provided.
