Review on BOSS Audio MCBK425BA Motorcycle Speaker System: 2 Weatherproof 3 Inch Speakers with Built-in Amplifier for ATVs, Motorcycles, and 12 Volt Vehicles by Ken Hamdan

Much better sound quality than Go-Hawk. At first I was skeptical about the price/quality. Looked through so many different bluetooth speakers for less than $200. So I gave it a try by mounting a Vulcan S 650 on a cruiser. I ride my bike daily, music is a must, freeway test at 70mph with a BAM full face helmet. I still listen to my music on the freeway. Highly recommended! ! ! BOSS did a good job here, but if you want the sound to be louder than the 4-speaker version, lol. Hope this helps, enjoy the ride and stay safe. :)
