I have a set of Polk audio DB651 and a set of infinity kappa 62.9i's. Also a set of direct replacement tweeters for the front. The Polk's will come with factory plugs so all you have to do is pull the old speakers out and plug these in they will also come with adapter rings. The infinity's were in the sound bar you will have to cut the OEM plug off to wire these. The foam ring on one of the infinity's has a tear but didn't affect the sound any. The tweeters lock right into the tombstones on the dash. Looking for 80.00 for everything shipped.
