I upgraded my stereo on my 2010 Ultra Limited by installing an Alpine KTP-445 Amplifier and a set of marine grade Kicker Speakers that are designed for the Harley Batwing Fairings. The fronts were KS5250 and the rears were DS5250. I took a ride and was not happy with the front speakers. I did a little research and purchased the Polk Audio MM521 marine grade speakers for the fronts. I removed the outer fairing and installed the speakers. The Polk speakers have a crossover that wires directly into the original wires that were attached to the Kicker Speakers. I also run a Hog Tune Tweeter Bar on the front inner fairing above the CD player. I was pleasantly surprised with the vast improvement of the sound sytstem after install of the Polk MM521 speakers. Volume, clarity and bass are all vastly improved. I am a happy rider. I only have to wipe the blood from my ears after turning off the stereo.

Great speakers for the price. Fit perfectly. Look good. Marine certified(Jeep in hawaii). As long as you don't have unrealistic bass response expectations you should be happy. Crystal clear. Aloha.

originally bought these speakers for my Jeep CJ7 but they did not fit so I put them in my golf cart combined with Polk Audio Atrium 4 speakers and these little gems really sound good. They were so easy to mount as well. The sound is as robust as a 5.25 speaker can get. Good mid tones and of course the tweeters are sweet.
