Summary: Always had good success with Kenwood speaker products. Bought these to upgrade from factory ones in my vehicle. Great soundind, smooth highs. Mounting hardware and installation instructions not so good. The surface mounting application was nearly impossible to figure out. The hardware supplied with the tweeters needed to be modified. I am wondering if the wrong hardware was packaged with these it was so hard to figure out.
Summary: Although the crossover is a bit bulky and was hard to get stuffed inside my dash, I managed with a little altering and a few cuss words! I love the way these tweeters give several mounting options! I chose to to a top mount in the corners of my dash. Good decision. The highs bounce off my windshield. I bought these before I got around to installing my previous Kenwood tweeters, the KFC-ST30 models. I got these for their higher frequency response and mounting options.
