Crutchfield Customer Review (What's this?)
I bought these for my 2009 Yamaha 232 Limited boat. The factory Kicker speakers are located inches off of the floor facing each other. They do a fine job with the factory Sony head unit as long as the boat isn't moving. With wind noise and the engines running at 9K RPM the music would disappear. These add-on tweeters put sound up closer to ear level. Now running down the lake at 30MPH we can still hear the tunes. They were easy to install and wired directly into the factory speakers wiring.
Pros: They look and sound great. They can be installed flush or surface mount. I used a hole saw and flush mounted mine. There is plenty of wire to reach the factory speakers.
Cons: You get what you pay for. JL Audio is top notch but it will cost you. The price is more than I wanted to spend but I know that I bought high-end audio gear that does exactly what I needed it to do.
