Review on BOSS Audio MCBK420B Motorcycle Bluetooth Speaker System - Compact Amplifier & Weatherproof 3 Inch Speakers, ATV & Motorcycle Use, 12V Vehicles by John Floyd

*UPDATE 09/10/19*This speaker system is far better than the best investment I've ever made in my wheelchair. Six months of regular use in the rain, mud and mud and they still play my music loud and clear as ever. After long use I can say that I am sincerely satisfied. Also, they seem to have relatively low power consumption since the 12V power supply I use has a capacity of 8300mAh and works with LED strips (purple lights on video) and speakers that play Bluetooth audio at a fairly high volume stream for about 12 hours. until you need to charge. I would add a star if I could but I gave them five stars when I installed them. I just bought them and put them on a wheelchair, hooked them up in parallel with my lighting setup and everything is powered by a Talentcell 12 volt power supply. The first impression is great. Loud and clear sound, yet well balanced. The volume in the video is not even 20% and I was concerned about the complaints from the neighbors.
