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.

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.

So far so good, time will tell about long term durabilityInstalled into a Honda pioneer 1000I needed to purchase clamps that would fit the 1 3/4 roll bar as the clamps that come with the speakers are only meant for motorcycle or ATV handlebarsAs many have said the speaker wires are short.I fixed this by using regular speaker wire and some heat shrink electrical splice connectors to make the wires long enough to run to under the front hoodThe unit itself is small enough and mounts neatly and easily under the hood.Everything works good and though the unit has no bass, the treble is really nice and it pumps some really good sound*4 year update*Still running strong with no issues

Speaker's fitted professionally. However drained my new battery so had to pay for an additional on/off switch. Sound quite loud but could do with a lot more bass. Also impossible to register warranty as American company.

Mounted these on my 2014 Honda Valkyrie after my JBL Cruise speakers stopped working.Pros: Much louder than the JBL, 400 watt waterproof amp, pre-wired plug and play connectors, includes wired volume controlCons: Terrible handlebar mounts, makes very loud full volume beeps when powering on and connecting to phone - volume control has no effect on these loud beeps.The Valkyrie has 1" diameter handle bars, which is very common in the motorcycle world. The brackets that come with the speakers utilize rubber strips to adjust for bar diameter. Two different thickness strips are included, 1/16 and 1/4. With the thin strips, the clamps would not hold the speakers in position. The thick strips were too thick and would not allow the mounting stud to stick out far enough to get the nut on. I was lucky that I had some 1/8 rubber sheet and made it work. The wires coming from the speakers have plugs mounted to the ends, so you cannot use aftermarket clamps unless you want to cut the plugs off to pass the wires thru the clamps, and them replace the plugs. I mounted the amp underneath my seat. The speaker leads (approx. 4 ft) were not long enough to reach the amp after routing them where they needed to go. The leads from the amp made up the difference tho, as they are approx. 2 ft long. This resulted in the plug-in connectors being under my tank instead of under my seat where I would have preferred. The lead for the volume control is long enough to allow mounting it virtually anywhere you want. The volume control does not come with any type of bracket, so you have to find a way to mount it. It does have a threaded shaft with two nuts, so fabricating a mount is fairly simple.Been raining here for two days now. Have not been able to ride yet and really try them out. My JBL's could be heard well at 60 mph, OK at 70, and not hardly at all above 75. These are so much louder that I feel they will be fine for my purposes. Cutting the wind noise out by using ear plugs will help you hear the stereo better at higher speeds.

I wanted a system that would give me clean music at normal listening levels and that would not draw excessive amps doing it. My Mule, and most motorcycles have batteries and charging systems are not designed for excessive amp drain. ( the Boss Audio MCBK420B only draws 4-5 amps) . I chose the Boss Audio MCBK420B Bluetooth system for my 2019 Kawasaki Mule and I am very happy with my choice . I installed the amp inside the glove box. In the dash mounted the volume control along with an additional on/off toggle switch. The 12v power is supplied thru a relay that is activated by the ignition switch per the instructions. I added the fore mentioned SPST toggle switch inline so I can manually turn off the amp when not needed. The speakers are clamped to a round frame under the dash that allowed them to face the occupants. I secured all wiring with ty wraps. This system is just what I was looking for. Music is clear, clean and it will play louder than I care to listen. The bass is a little lacking but sound quality is excellent for this size speaker system . Great bang for the buck and easy to install. The amp , speakers ,mounts and wiring in the kit are all good quality pieces and instructions make it relatively easy to install. If your looking for a nice minimalist sound system to enjoy some tunes in your UTV or SxS I would recommend you check this system out. If your looking for bone shaking bass and enough volume to scare the animals this system is probably not going to meet your needs. Happy Trails
