BOSS Audio Systems MCBK520B Motorcycle 3 Inch Stereo Speakers and Amplifier Audio Sound System - Bluetooth 2 Channel Amplifier, Weatherproof, FM Tuner, USB, SD, Auxiliary In, ATV UTV Compatible

Well I finally had a chance to get out on the road with this today. The volume was impressive I could not stand to listen to it at full volume at 55 MPH. The tone is a little "trebeley". but that is to be expected from a 3" speaker that is doing the full range of sound. The bluetooth worked well and the FM tuner is okay. I have not tried the USB or SD cards yet. I suggest going on Boss Audio's web site and reading the owners manual to fully understand this unit's limitations. I had to fabricate a bracket out of a piece of 18 GA stainless steel to mount the amp. You can see it in the pictures. I noticed that the reviews seemed to cover several models all lumped into one group. The unit comes with a 7.5 amp inline fuse in case you are worried about amp draw on your system. You can't really hide the MC520B in a saddle bag because of needing to get to the controls unless you just wanted to use the remote. I thought the remote would be dangerous to use on the road as a driver. However my wife loved being able to control things from the back seat. I will try and update this later and see about durability. For the price, you can't go wrong with this. Update: I got some SD cards to use with this and loaded a bunch of music. I had a problem with it just sampling the first 5 to 10 seconds of each song. I went back and converted all of them to MP3 format and it works great.

I can hear on my Harley with Vance and Hines pipe doing 75 mph. Base isn’t the best but has quality sound. Wires are a little short though.

I installed this stereo on my 1997 Honda Shadow ACE 1100, and it works very well. Install: I had to improvise a little mounting the speakers on the handlebars - the brackets were too big to clamp down on the handlebars, and the rubber-spacing strips included were too thin, and too thick. So I cut some strips from an orange rubber mat I just happened to have, that were just the right thickness. I ran the speaker cables under the gas tank, and under the seat. The included wires were just barely long enough, with the connectors ending up under the seat (beside the air filter, which is centered under the seat on this bike). I mounted the main box of the stereo in my saddle bag so it's out of the way and protected (I'll control it with the wireless remote). I had read some reviews that the unit still draws a little power even when it's turned off, which drains the motorcycle battery - therefore I installed an extra switch that totally disconnects it from the battery (I installed this in the corner of my saddlebag, so I can snake my finger in and turn it on/off without opening the saddlebag. Use: The main feature I liked on this stereo is that it will play mp3 files on an SD card (you could also put them on a USB stick, but that sticks out farther, and prevents the protective waterproof rubber cover from fitting). It's also cool that it has an FM stereo in case I get tired of my songs (be sure to read the directions on scanning/pre-programming the local FM channels!) I just use an old flip-phone so I haven't tried playing music via bluetooth yet, so I can't say how easy/good that is. One thing I was pleased to find is that when I turn it off/on via my power kill switch, it still remembers what song I was playing on the SD card, and resumes where I left off. The wireless remote is a nice touch - right now I've got it hanging from the handlebar, but I might put it in a more secure place later. Seems to be a pretty cool little stereo - I recommend it!

Great system. We can hear it clearly even at hiway speed with full face helmets. Not much bass but it was expected per reviews. Fast shipping and easy install. Update: I've had this for a couple years now and it still works great. I made a mount for the amp and attached it with the batwing mounts. That way it's covered pretty well but gets plenty of air. I use a memory stick and the FM and still works and sounds great. Speakers are on the bars and somewhat covered by the 3 pocket windshield patch. They've been thru constant 95° days, cold(38°) rides and downpours. No complaints. As far as draining the battery, wire it thru a relay that's run thru a circuit that shuts down completely when you shut off the engine, not just straight thru the battery.

Ur item snapped from vibrations of my harley and can not be fixed because you tac welded a Screw for the speaker support, and that tac weld being the weak link to the speak, now I have a busted speaker. Ur product is cheap and not durable enough for a Motorcycle. Worst waste of money so far., not to mention theyre not loud enough, and they cant stay connected to my phone. Zero star

Great system and sounds good for the cost BUT there is no mount for the amp?!? Need to be a little handy to make your own!
