As expected

Nice sound

Speakers not working

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.

ممتاز ويعمل بسكل جيد

I bought the 4 Bluetooth speaker set and really only needed the 2.. fitted the 4 as they look Wicked..well pleased

Speaker mounting broke within a week of installing them

Easy install, louder then I was expecting sound quality is high on the highway at 120km/h in 55km/h winds I was still able to hear my music and enjoy it without turning the volume all the way up
