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.

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.

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

Good bang for your buck speakers

The media could not be loaded. These speakers seem like a good bang for the buck. Have them on my super magna. They seem to have good sound and are very loud. Not much bass but don't need bass to enjoy the music. Fairly easy install hardest part was finding a spot on the handlebars,and finding a spot for the amp. Will give it 5 stars after I get out on the road with them and put some miles on them and see how they hold up

Working Well!

Let me begin by saying I am not a handy person. I am lucky to put gas in the tank. So I had been looking at these speakers for over a year and was just intimidated by the electrical work. I had read several reviews about using kill switches and watched various videos about how to properly wire this. I bit the bullet and bought it a few weeks ago.I continued to watch videos and even asked my father-in-law about the wiring. I am quite proud it took me only 2 trips to the auto parts store. I basically got everything hooked up and then set about attaching it to my motorcycle. Honestly, the biggest challenge was attaching the speakers to the handlebars. It would have gone much quicker if I were an octopus with fingers on each tentacle. But I got it done. When I hooked up the wiring and turned on the switch, I heard the beeps! I was ecstatic! It works!!I am still working on the excess wiring and keeping it safely tucked away. I have a few ideas though. I just want to make sure it does not fall out, especially if I'm out riding.As far as quality, the volume is not the issue. I have yet to go above 45-50 mph with it on. It is plenty loud for kicking around town. Bear in mind while it does have an amp, it is just two speakers. This is not like going to the movies or having surround sound in a man cave. Nonetheless, it works great for just listening to your choice of music (and having other people hear it, too!).Overall, I am very happy with these speakers. I am so glad, too, I installed it myself.

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.

Definitely Worth the Price

So far so good, installed the amp on a 2021 HD Electra Glide inside of the front fairing above the tray in the dash board. Tapped into switched power at the cigarette lighter/12v power socket.Extremally easy install, toughest part was getting the speaker mounts to be tight enough on the handlebars but went smoothly when is used the thick piece of rubber cut into 2 - 3/4" pieces and just used those 2 smaller pieces to get the mount to fit securely. (1" bars).Bass is a bit light but volume is good. 65+ mph with a half helmet. Haven't tested yet with my full face.Bluetooth connects flawlessly to iphone.I would say these are absoluteley worth their price (as long as they hold up - time will tell that). You can also swap in a better pair of speakers later down the road with more bass. The amp will work with any speakers.So far, very happy with this purchase.
