Good job, they look nice!I have had the Polk tweeters installed now for a couple of days. . .
Sound quality is noticeably improved with dash tweeters that actually do something. In particular the "sound stage" has been lifted up with much better imaging.
I used to have the treble up one or two notches and now have it turned down a couple of notches. I haven't yet decided whether or not to cut the attenuation wires on the crossovers. . . CDs sound hugely better. On the other hand I do listen to Pandora radio a good deal in the car and the new tweeters reveal the limitations of that sound source with the highs being a bit harsh at times.
Overall, the $50 I spent here gives a lot of bang for the buck!
