    • 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

    • 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

    • 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

I bought this for my golf cart. It has been amazing. We ride our golf cart in parades and the music from it is awesome, my grands get a kick out of the lights when it’s dark. It is a very good product and my son is buying one for his golf cart. Would definitely buy again if I needed to.

    • Worth the money!
Style: Classic
I installed this on my 19 Kawasaki Teryx. Pretty easy to install. Just removed 4 bolts on the roof to lift up for easier access to the mounting screws. 12 volt plug was long enough to run down the side and to the rear 12 accessory plug on my Teryx. In the future I might hardwire it but for now the plug handles the power with no problem. For me it gets plenty loud. We do alot of hill climbing so we are not haulin azz all the time. Sound quality is real good and have no distortion when on high volume at least with rock and metal music. Came with 2 remotes for the soundbar itself and to control the LED light function. You can easily shut off lights if need be. Bluetooth connection is automatic with my Iphone 11. It wont blow you out of the water but it sounds great for the money. Highly recommend. ... show more

Item came broken. When trying to replace, I was told that there was no option for replacement. Sound quality is okay, but due to the item being broke, I’m sure the sound quality is off.
