    • Great product!
Style: Classic
This sound bar delivers exceptional clarity and volume even in noisy off-road environments. Installation was straightforward with the included hardware, and the Bluetooth pairing was seamless. The RGB lighting is a nice touch, especially for evening rides. It feels rugged and weather-resistant—ideal for ATVs or UTVs. Excellent value for its size and features. Pros: • Loud and clear sound • Simple Bluetooth connection • Durable, all-weather build • Eye-catching RGB lights Cons: • Slight delay when using aux input ... show more

    • Best budget sound system, hands down.
Style: Classic
some people complain about this not being loud enough. I am someone who loves things loud. I can say with certainty that is the BEST budget sound system you can buy. Sound quality is 9/10 (bass is eh but I don't expect bass from a sound bar, I usually crank the treble up and reduce bass). this thing is very clear and very loud in this budget category. NO, it won't compete with a $700-900 JBL. It's not trying to; this is plenty loud for the average guy. I have a Polaris RZR 900 with a stock exhaust. It is plenty loud. I highly recommend this speaker if you are like me and have been using a tiny portable speaker and don't want to spend $1000 to have a sound system. Bonus The lights are bright, and the thing works perfectly as expected. quality in the build is also 9/10 ... show more

    • WELL BUILT, GOOD SOUND, GREAT VALUE
Style: Classic
After a lot of research and reviews read i bought this soundbar for my 2021 EZGO Valor golf cart. It made it to my front door way ahead of schedule. Right out of the box i could feel the quality. It is a well built soundbar. I mounted it underneath the rear section of my cart’s top and was actually able to use the two existing bolt holes already in place where my cart’s top bolts to the frame. I did have to use slightly longer bolts and some washers as spacers to create a gap between the speaker and the roof so that the speaker sat at the best angle. The bolts and washers cost me 6 bucks at Lowe’s. I was able to mount it to the cart myself however some help would have definitely been welcomed. The wiring was simple. I simply tan the wiring down the top’s frame rail down into the engine bay and zip tied it neatly. Then i fastened the provided ground and positive connections to the battery and it was ready to go. Super bright lights which you can dim from your remote control. Many different patterns and color variations which are also controlled from the remote. The sound is perfectly clear and has several EQ settings. It is plenty loud. I expected a little bit more bass out of it but it definitely has enough. I would recommend this soundbar to anyone looking for exceptional sound quality and lighting without breaking the bank! ... show more

    • It is a great product but the delivery was long, sent to wrong address, canceled order.
Style: Classic
This was one of the worst purchases that I’ve made from Amazon. Amazon used their ”Amazon gray van" delivery for this item. Delivered to wrong address, Amazon customer service had me looking outside and through my bushes late at night saying it was delivered to my home. They did attempt to send me a replacement item. 5 days later my neighbor comes over with my package where it was delivered to. I returned the original sound bar and had them cancel the replacement sound bar. I ordered from Best Buy within minutes of canceling the order. The sound bar has decent sound but I was expecting better. Mid volume is great, high volume breaks up and is distorted. I need loud quality volume for my SXS when I’m riding the trails. For the remainder of this season it will work ok but I have to add 2 additional speakers or replace this sound bar for next season. It is a good price for the sound bar but I wish I paid the extra $$$ for a higher quality / louder sound bar. Now I will be spending more $$$ most likely on additional speakers. ... show more

    • We love this speaker!
Style: Classic
Installed this durable speaker in our Polaris rzr. It’s loud and durable. I love that it has any choice of connection although we stick to Bluetooth. It’s easy to install. Cords are a good length and work with the speaker above our head. For the first two weeks I was frustrated that we could turn the color off when driving through town…but the remote finally kicked into gear and turned them off. Even fun to mess around and turn your buddies lights on an off out riding. ... show more
