Went to my local stereo shop to find replacements for the Clarion speakers that came on my Mastercraft, and was told nothing fits in the tweeter mount. So Dave at Stereo King and I came up with an idea to build a new mount that will take Infinity or Kicker tweeters. I'm building the mounts using solid cast fiberglass with black gelcoat.
If anyone is interested in a set of these send me an e-mail.
