I got all 4 speakers from a guy on eBay. They were used, but he did an awesome job packing them and they look brand new. Paid $80 which included shiping to my house. I looked at Best Buy this past weekend and the 3-ways sold for $83 and the 4-ways sold for $107. $190+ 6% tax (for me)and you've got $201.40 for new. This should work out to be a $121.40 savings by going used. They also came out of a Ford, so they have ford connectors on them. No snipping, no soldering, just hook them up...
I'll post an update after this weekend when I get the speakers installed.
