BOSS Audio Systems MC470B 3 Inch Motorcycle Full Range Speakers and Amplifier Sound System - Bluetooth 2 Channel Amplifier, Weatherproof, Volume Control, ATV UTV Compatible

I read a lot of reviews before buying, I hope this review helps you. The initial installation, primarily the clamps on the speakers take a long time and a certain amount of patience to get right. I think is spent about 3 hours for the complete installation. I'd like to say something negative about the brackets but they kept the cost down by making one size bracket and supplying a couple different sized rubber "spacers" that are not easy to handle. In hind sight I might have lightly glued them in place before installing to keep them from moving around. I installed two speakers on the handlebars and the other two on the crash bars, they sound great and my passenger has no issue hearing them, even with a full face helmet. I dropped a little silicone down the opening of the speakers on the crash bars to keep water from entering because of the orientation I had to use. I used the windshield bag to mount the amp and to tuck the wires away. I was very impressed by the wire connections to the amp. No soldering required unless you need to mount the amp further away from the speakers which wouldn't be that big of a deal. If they made the wires longer people would be complaining that the wires are too long. I mounted the volume control with a couple zip ties to my Ram mount and it works perfectly. I may make a bracket and move it in future. Another complaint I read a lot was the lack of bass in the speakers and not enough volume. Do yourself a favor and look at your phones equalizer and adjust it for extra bass and make sure your phones volume for media is up, it makes a huge difference. I have a Kawasaki Vulcan 1700 with stock exhaust and at 80 mph in traffic I only need to turn up the volume half way. The amp is not 1000 watts, more like 100 watts but it's got plenty of power and small enough to hide just about anywhere. Overall I'm extremely impressed with the quality, especially for $99.

I installed these on an older 99 Kawasaki Vulcan Nomad. They took about an hour to install and I don’t know a ton about mechanics or electrical. I didn’t really even use the instructions , it’s pretty much straight forward.I also was installing a usb charger so I spliced this with that. The clamps for the speakers are terrible but it is what it is.I installed 2 on my handlebars and2 on the highway bars. The sound quality isn’t amazing but you can’t expect insane quality control out of three inch speakers. They are loud, I have Vance and Hines straight pipes that are loud can hear no problem in the city. In the highway at 70mph I can still hear the music with a full face helmet on. I haven’t been faster than that with them yet.I ran the wires to the amp under the gas tank and put the amp behind my fairing. The inline volume control I was planning to just hide with the rest of the wires but that’s also the shut off so you don’t drain your battery. I mounted that near my left handle. Overall I’m happy with them, but the amount of excess cable is kind of crazy. For now it’s zip tied behind the fairing but it’s ugly and there’s no way to hide this much wire.

Mounted on 2007 Harley with stock handlebars. The rubber grommets are a pain in the butt. It comes with two sizes. One is too think and the other is way too thin. Only way I could find that would work was to break the thick ones in half and use on one side of the bar and use a thin one on the other side. I can see why some folks say the mounts break. There is so much tension if you use one solid thick rubber grommet. It can be installed by yourself but it helps with two people.The sound is pretty clear and louder than the stock audio system on my touring bike. Only complain I really have is that I didn't really think about how big the speakers are and it looks a little goofy with all 4 on the handlebars. They barely fit on there. I think I will try to figure out some other way to mount them that I can easily remove them what I don't want them on there but for now the stock mounts will work. I am taking a road tip next week so I will come back and update after that trip.Update after trip. I can hear music going 75 with a windshield. However without the windshield I can’t hear anything over 40.
