Golf cart music setup!

East setup on a golf cart, not to large, quality of sound was great, easily connected to the golf cart power, and Bluetooth setup isn’t challenging at all. Value for your money for hours of entertainment!

Well-rounded speaker for many different types of music

These things are awesome. I put a 20-amp 12-volt converter on my 48-volt trike. So, now I bike with Bach, Beethoven and Brams it is so great. I get so many thumbs up.

Need to sell some of the parts separately so can buy when break

Speakers sound great if the volume knob provided didn’t break I’ve had them on my bike a couple of weeks and had no trouble with them and all of sudden I have no volume when I turn the knob it clicks and sound's like they are connecting to my phone but nothing and then on top of that I can’t turn them off either so they are constantly giving out a bong noise so had to take them off the bike so great sound but waste of money all through the power knob provided is pretty silly and breaks

Good Value amp and speakers.

The media could not be loaded. Installation was pretty straightforward. There was plenty of cabling to route everything out of sight. Sounds decent, not much base as others have said, but it gets plenty loud enough to hear it at highway speeds. Speakers mount up tight on 1 1/4" bars. Thankful for the extra length on the lead for the power/volume controls allowed for mounting on my 14" ape hangers.

Good sound quality, but they don't last.

Great while they last.I've gone through two sets of these already. They both blew out in about a year, first one was warranty swapped, but the replacement didn't fair much better.The right speaker was just starting to go when I put my bike in storage for the winter, when it came back out the speaker was just completely blown. I'll be looking for a different brand to replace these now.

Amount of sound

This is my third different system that I have tried.You must have at least a hundred Watts or more to hear at high speeds. I was able to hear the music at only three quarters volume at over 70 mph. Just remember when you connect to Bluetooth on your phone make sure your phone volume is all the way up and use the volume that comes with the system that you're able to attach to handlebars.. if you're looking for a lot of bass you're not going to get that with this system but you will get a very loud system that you can hear it almost any speeds. System was very easy to install to the battery and I used the quick disconnect on the positive line I mounted it up by The handlebar so I was able to disconnect it when not using that way the battery will not drain. My main concern was being able to hear at highway speeds at 70 miles an hour or above and this system will provide that. good luck to you all

Say no to BOSS products!!!

If I could have a no star option I would have chosen that one. These speakers are the second pair I received and they are complete trash. The brackets break easily and the quality is awful. I reached out to the seller that sent me a refurbished set and lo and behold I was sent more trash. The speakers would not work and the one that did work was like listening to a whisper. Save your money or spend a little more and get a high quality brand that's worth your hard earned money. I will never buy another Boss product.
