Great system for my Kawasaki Mule SX

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

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.

Nice inexpensive speaker alternative

Good quality speakers for the price. Install was pretty easy on my 2017 harley low rider. The speaker clamps are a pain to install securely with the rubber spacers but once on and tight they feel plenty sturdy.I had these on my old sportster years ago. They were great back then. Havent tested these on my new bike but on my old sportster they were plenty loud. Could hear pretty clearly at 65 with a full face on. As others have stated there is just about no bass but thats to be expected at the price and size of these speakers. Everything else is loud and clear.It seems like they changed the loud bluetooth connection noise. It wasnt a super loud sound like it was with my old pair.Would buy again.

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

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.

Eh, Not Worth It *EDIT* Meh...Sure.

I always wait for a bit before I write a review because I want time to use it. It allows me to be real and fair. This, for the price, seems pretty fantastic. From a looks standpoint, it fits the bill. I have a black motorcycle this is attached to, so the matte black option makes it blend right in. Appearance, it's a 5*. Now, the reason this gets only 2 stars from me is for a couple of reasons.First and foremost, I purchased this about 2 months ago, and already, one of the speakers is blown. I always treat new speakers the same way; I run them a variety of ways to break them in. Well, I guess I did literally break it in. I would have it on with the volume way down low and up high and ranges in between, and about a week or two ago, the right speaker is blown. So, from a quality standpoint, that knocks it down immediately.As stated in other reviews, the sound quality is ok at best. Volume, this thing can get pretty loud. However, it doesn't have a great range of sound, from bass and treble. It just gets loud. Now, you can definitely hear it at highway speeds with a full face helmet. Half shells, brain buckets, whatever you want to call it, you definitely hear, until the wind gets to be a bit much. But what stands out is the lack of quality sound.Installation wise, it really isn't terrible, but it definitely isn't easy. It contains what is needed, but it is bare minimum. I added an additional kill switch so it will cut off with the engine and not stay on all the time. That's more of an annoyance, especially with how motorcycle batteries work.So with all that said, I wouldn't recommend it. It's a cheap price for sure, so I guess if you want an easy starter kit, go for it. However, I feel like I'm already forced to fix/upgrade, so this $60 some odd could've went for something better.EDIT**** I updated it to three stars. I wouldn't say it blows you away by any means. I still don't like that the speaker blew within the first few weeks of having, and I didn't even have it on full volume. That said, it holds up well in rain, and replacing the speaker with an at least decent quality 3" speaker makes it decent. I wouldn't say it's the best ever, but for the price, ease of installation and compatibility, and look, sure. Go for it if this is your budget.
