I used the same polks on the Wing and they do sound a tick better but could use an amp. You get a bit more volume and bass but not a huge difference. Again needs an amp. For me they fine and you can hook the stock tweeters up as well. you do have the grind the trim on the speaker a bit to get the dash bezel back on but not to bad a job.

The F6B is fine for me I put my OEM Wing windshield on which flows nicely and make sure you turn the auto volume on makes a big difference. Oh and the sound enhance whatever they call it. Hold the MODE button down and it's in there.
