i recently bought an 81 corvette that had a complete crossfire system (amp, sub, 6x9 & 4x6) installed. i pulled the sub/amp out and have them up for sale, while I was redoing the speaker wires for a new headunit, I noticed the speakers weren't factory as I had thought. After getting the 6x9s out I seen they were Crossfire RS69 series speakers. The fronts are the same but 4x6s i believe. I am just wondering what these might be worth. I am going to be rewiring the whole car and going back with a factory radio and speakers. just could use a little extra cash...if anyone can help me out and value these for me...thanks
