BOSS Audio Systems MC750B Motorcycle / ATV Speaker System - Bluetooth, Weatherproof, 4 Inch Speakers, 2 Channel Amplifier, Volume Control, Ideal With ATV’s, Motorcycle’s and 12 all Volt Vehicles

Pros easy to instal..very loud even with loud pipes...cons..large speakers so look at measurements. Also you will need a toggle switch witch doesn't come with it.. so all in all we'll worth the money

I bought the MC750B audio system and man to these things put out. Installed them on the handle bars, little bigger then i thought, but sound awesome. Connects to phone great. I have a windshield so can't say about a bike without one, but the sound is super loud and clear at 75-80 on highway. It's really to loud to have all the way up in town. I wear a helmet so probably even louder without one though i wouldn't recommend riding without it. Just installed 7-25-18 and will up date.

Ok. These things are huge. And they don't have great fidelity or bass response. Or external controls (your phone does all the controlling). BUT they are LOUD AS HELL. I have a Harley Street Bob. 1700cc with straight pipes. And I can hear these speakers at a little over HALF volume going 70mph! Full volume is almost unbearable while sitting on the bike. It's easily installed, too. As far as inexpensive aftermarket speakers go, these do the job for Harleys nicely.

Was skeptical because of the low price, but I've had sooo many people compliment the way they sound. I can hear them going 60mph. I bought a switch and wired them straight to the battery and I have had them on with the bike off for an hour without the battery dying. I put the volume knob and switch just under my seat where I can reach easily while riding. Perfect waterproofing as my bike lives outside 24/7 in Oregon

Absolutely terrible sound and even with the supplied amp they sound poor and anything over 20mph and if you have pipes you can't hear them. Used once and back in the box with every thing like brand new. Al take $50 if you want them.

Bought this hoping it would have a better sound than the 3 inch speakers. It has a T iny bit more rounded sound but not much difference. As for the power, I knew it wouldn’t really be very loud. Hate it when products say “300 wards” when the rms is a lot lower. I could hear these at highway speeds, but not clearly. I do like the look of them and will be trying to change the 4inch speaker for a good speaker, which was my main goal.

When I ordered I didn't realize how big the speakers were. Also they are loud but no bass like I would have thought being 1k watt Amp.

great sound, i mounted them on the handle bar and the amp under the seat and without the windscreen i could hear clear music till about 75mph and with the windscreen i could hear 100+ mph they have been rained on about 6 times and still work perfect
