I have a nice set of Polk 4x6s I don't need anymore. They're model GXR46, two way coax's. Come with an adapter to hook up to factory wiring. They're in great shape and sound nice. I just changed the setup in the SD they came from (installed a late '86+ rear fill so it has the ~6.5" out back.)
Anyway, I'm lookin for $30 shipped to you insured to the lower 48. PM or post up if you'd like them.
