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

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.

Sounds great! Cheap way to put a decent system on your bike. All I could ask for! Very good quality! Not a lor of base, but great sound!

This is a good audio kit considering the sound quality and features you get for the price. A few little designs adjustments could make these a lot better though.

When I was asked to review this product last time, the seller said they would contact me and they never did pretty much took it off the bike and just sitting there in the garage At this time, the quality in the unit seem to be a nice construction, but as far as volume, it is not very loud I can hear it at an idle and as long as I’m going about 35 miles an hour after that really kind of sucks

I bought this amp because it was one of the few systems you could plug in an SD card or USB stick loaded with mp3 files and just play them. From that stand point, it's great. When you apply power to the amp, it comes on and starts playing the mp3 right where it left off. That's actually a great feature because the remote supplied with the stereo is pretty poor. As others have mentioned, the plus and minus buttons are used for multiple functions so you never really know what you're adjusting. With the amp mounted out of sight, the buttons on the amp are not generally accessible.The amp in general has plenty of power and would have good sound quality if it weren't for the crap speakers that came with the system. The matte black housings look fantastic. I was a little disappointed in the lack of low end, but I figured that was understandable for a 3" speaker. Unfortunately after less than 6 months of use usually around half volume, both speakers crackled loudly and never sounded right again. I connected some much larger 6x9 speakers I had setting around and they sounded great! While doing some research looking for replacement speakers I was unable to find any that would fit in the housing, but all the 3" speakers I found were rated at about 15 to 30 watts. I found that to be amazing for a system supposedly rated at 600 watts.So, I guess what it comes down to for me is I think the amp is worth the price I paid for the system based on the way I planned to use it. If you buy this, expect to buy new larger speakers if you really want it to sound good and continue to work. Don't expect to be able to easily adjust volume, change stations or switch from radio, to BT, to SD while riding.

I love this. It was perfect, it played my flash drive. Speakers, not booming loud but they were right for me. I don't need that loud music.

Have the system for six years so far. There is nothing like having music while you ride and not be tied down with earbuds or helmet speakers. Pretty basic wiring, radio is a little sketchy, but I just use the Bluetooth and listen to my music. Remote control is a little testy sometimes but I would still give this a five star because of how much I enjoy it. Great value and worth the price.

So install was easy. However, I have issues with the sound quality. Anything over 45 mph you cannot hear the music clear. The other issue I have is the amplifier gets very hot when in use. I have never had an amplifier that heats up that much. Not happy with this product at all. I will be looking for something else to replace this with.
