BOSS Audio Systems MCBK520B 3 Inch Motorcycle Speakers, Bluetooth Amplifier

Put these on my riker 900. The sound was pretty awesome when I got the speakers hooked up. Good set for the price.

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.

Good product, only defect is that at maximum volume the sound is not very clear

Theses have been awesome, put them on my fourwheeler they have gotten wet so many time can’t even count it on 2 hands I have sprayed water on the front of it to get mud out of the speaker still worked perfectly fine only complaint I have is that my Bluetooth is a little iffy has to be close to amp to really even work good but to me they sound fine. And will 100 percent but Agian for another fourwheeler or something. And for a 100 dollars it’s a steal if you ask me. Beats having headphones in your ears where you can’t hear over wind 😂

Loud decent sound, but they only last until you're just past the return period. Weak clasps, on broke without any impact to cause it. Still trying to figure out a way to get my money back as I've had them just over a month and they are no longer working. Absolute waste of money if not resolved.

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.

Works great really loud look good too

I installed this unit on my excavator. Sure the sound quality isn't a 5/5 stars, but again for the money it certainly isn't bad. What I am impressed with is: I installed an external power isolation switch, and simply use it to turn on and off the unit. It powers up without having to touch the power switch on the amp which is installed remotely. It also resumes playing my USB where it last stopped- some brands start over at the beginning on each power cycle. The speaker wires aren't real long, so you may need to extend them which is not a problem.

i would like to appologize for my last comment it was all a big mistake the sellers of this product was kind and considerate and i take back what i said. Mass Design is the best
