Review on 🔊 Polk Audio DB522 DB+ Series 5.25" Marine Certified Coaxial Speakers - Black by Carl Movahed

Harley Ultra Rear Speaker Upgrade. Easy install, sounds great. Harley Davidson factory stereo output - 2 ohms, Polk speakers - 4 ohms. Definitely an improvement, I don't want to blow stereo 4 blocks just better sound and more bass than what I had. Factory unamplified stereo/CB - they sound great and are waterproof. As a significant improvement over the factory speakers, a front fairing kit is also fitted to upgrade the factory 5.25 to 6.5 speakers.
