Conclusion: i bought these as replacement speakers for my TJ and could not b happier. Hooked them up to a small amp, and the sound couldnt be better for the price. and being that they are marine grade, a little splash from the hose every now and then after a little play time, wont hurt either.
Conclusion: These speakers have the ability to be loud especially given the right amount of power. I have used these polk speakers in several applications (coolers, golf carts, my truck) and I have been very pleased with them. The highs can be very harsh at times, lows are ok depending on application (work great in coolers, lacked a little with golf cart baffles). Inside the truck they are okay. Definitely an improvement from stock speakers no doubt.
Conclusion: These are one of the best speakers you can buy without getting into components or needing to run an amp to them to make them loud. They are very crisp and have no distortion when the music is up louder. I would definitely buy these speakers again.
Conclusion: I recently changed out the sound system on my 08 Harley Ultra Classic. I put in a set of the Polk db5251 components in my fairing. They sounded so clear I just knew I needed to get a set of these for my rear speaker pods. Installation was a little tricky. Thanks to Sonix and their line of spacers I got them to mount. The db521 are powered from the factory radio and the db5251's plus my Polk MM DVC 8 inch sub are being run off a rockford fosgate pbr300x4 amp.

Conclusion: Got these speakers to replace stock kia speakers. Ended up keeping the stock speakers because these ones have terrible bass output. They were great for full range, almost making music sound 'live' - everything was good but the bass, so they had to go.
Conclusion: Plain and simple. Just a great speaker. I used them on my motorcycle fairing. I used 4 speakers with a jvc power unit cd player and being they are marine grade i don't worry about the rain.
Conclusion: Installation was easy. I do NOT recommend. The speakers did not last 3 months. I don't listen to loud music but need to hear the speakers when I have the top off my Jeep. They did't sound much better than the factory speakers and one doesn't even work now.
