EDIT 5/19/23: Over a year later and these are still functioning exactly the same as when I installed them. The sound and volume remain the same, as well as the speed of connecting to my phone. All wiring and physical connections are good. No issues. Still 5 stars for me. ORIGINAL REVIEW 4/22/23: I'm not sure if other reviewers received a different unit, but the one I got is great. The one I received had an inline fuse and power switch, and seems to be robust, although I've only riden with them for two days, so time will tell and I'll update this review if anything changes. The installation is very simple, and I was glad to see that the speakers fit on my risers and nested pretty well in the speedo and tach humps in my t sport fairing on my fx softail. Like I said, I'm not sure if other reviewers received a different unit, but this one is plenty loud at 70mph with my 96in motor and short shots. In fact I don't need to turn it up all the way to clearly hear it, maybe 75%. The sound is fairly flat eq wise, and at lower speeds it has okay bass, but the limiting factor is the size of the cones. But here's the thing, when riding a bike, your ear has trouble hearing bass frequencies anyway, and the loudest sounds will be mid-high. It's not that the unit is bright on the top end rather that the signature is flat, and higher frequencies can be piercing at high volume depending on the track, but I don't find it fatiguing if the volume is adjusted accordingly. I think these speakers are a good value for the cost and sound, I'm happy with my purchase, and I'm glad I bought these over the cheaper options. ... show more

    • Will be buying these again!
Style: Two 3" Black Speakers
They sound great and have a good connection for Bluetooth. I can hear them inside our house when my husband plays them outside and it’s pretty clear even in the house! There is plenty of cord length for hookup. They are on my husbands motorcycle and he wants some for our fourwheeler as well. They work great and are nice looking while feeling well made. These are nice, durable speakers for a good price! ... show more

    • Good for the money. Not water proof
Style: Two 3" Black Speakers
These are easy to install and have great sound. I can hear my music going down the road at 70 miles an hour. I didn’t get five stars simply because if they get wet from rain, they will crackle. Once they dry out, their sound goes back to normal, but it says weatherproof and they are not.

    • Honda Vt750
Style: Two 3" Black Speakers
The media could not be loaded. My bike isn't loud. The speakers are pretty loud. I can hear them going higher speeds. It does lack bass but maybe I can adjust that with an app on my phone. I just wanted some music more than anything, but other than the bass, the sound quality is good. I listen to all kinds of music genres as well. Install was easy. I ran the wires under the tank and hooked them to the battery. I also ran LED lights to my battery prior, and it's no problem at all. For the price especially, they're great. ... show more

    • No bass
Style: Two 3" Black Speakers
Nice, easy install. A lot of extra cord for a rebel. Had read sometime saying they didnt have enough length for their harley softail but that would honestly surprise me. Biggest criticism is like no bass but I'd seen other reviews saying the same. Nice and loud to cut through the wind at higher speeds. The 1st one I bought had a defective Amp or dial because when you turned the knob, it did turn on but as you kept turning the knob, the volume did not increase as it should. Called Boss and they were willing to just send the left speaker replacement (w/ the internal Amp and dial attached) however after further looking into it, they supposedly didn't have any left ones in their warehouse anymore so not sure if that means it's a common defect or not. Anywho... I got an entire replacement set and it works fine. You get what you pay for though as far as no bass. Otherwise nice enough. ... show more

    • Turn off the power switch when not in use.
Style: Two 3" Black Speakers
Excellent setup, with the equalizer in the speakers, it’s easy to connect with your phone. The on / off switch is a necessity, if you don’t turn it off after riding, it will drain your battery. Sounds great, I know some people were whinny about no base , but it’s for a motorcycle not your boombox.
