JBL Stadium UB4100 Powersports is rated 4.1 out of 5 by 9.
Rated 5 out of 5 by from Keep the party rockin' on the water! I bought this the beginning of last summer to use on my wake-board boat and it has been awesome! It is super easy to setup and use. Once it was mounted, which took only minutes itself, it was working within 3 minutes. The battery lasted all day and it was loud enough for all to hear very clearly. Do not underestimate how LOUD it is. I think people on the other side of the lake could hear it clearly. Bass and clear and hard, highs are crisp and the mids are just beautiful! You can't go wrong with the UB4100!

Rated 5 out of 5 by from Awesome sound!! A little pricey but so worth every penny!! Gives a clear sound at low or at a booming volume! With other Bluetooth speakers we were unable to hear over the sound of engine and riding on our UTV, this JBL gives us exactly what we were looking for. Now all our friends are looking into getting one as well! Don’t wast your money on other cheaper brands. This is well worth it!

Rated 5 out of 5 by from Overall good quality soundbar with simple install Tried this product recently in a RZR 1000 after seeing it featured in an ATV mag. I was pleasantly surprised at the sound ease of install overall. Not needing to cut holes for a switch was a huge plus as all buttons are integrated into the bar.

Rated 5 out of 5 by from WOW!!! Great speaker for Golf Cat I have been searching for a speaker to put on my Ezgo golf cart for several months. Listened to several and none were perfect. I did buy this unit with out hearing it thinking if they get great sound out of their small Bluetooth speakers I would be pleased with this big guy. Boy was I right. This thing is built well like a little tank and The sound is amazing. Louder than I need and crystal clear and plenty of base. I have not mounted yet just put in my front basket while I was spraying this morning and I had 3 people ask me where to get one. This unit is far better sounding than the bazooka tube and because the base better than the stealth. Great product. Thank you. if I had to offer suggestions I would say to have a connector at the unit for both big leads so you could remove the unit easily and not have that extra this cable if you don't plan on hooking to another device but these minor suggestions do not take away from this unit.

Rated 4 out of 5 by from great sound and good look. The mounts are cheap. I really like the sound bar. The sound is premium even after they hit the water, dust, and mud. I cleaned them off and they still sound the same. I did not like how the braces were faulty and one broke after my second ride with them. Overall, i mounted it different and they still work. They hold up to hard impact. You can't beat the sound and the bass is smooth.

Is there a way to mount the soundbar to the flat rails used commonly in golf carts? They do not use tubes as in side by side vehicles

Asked by: Ready Eddie
I bolted a piece of square metal between my back to roof brackets on golf cart and it mounted perfectly

can i put this in a jeep tj

Asked by: austin1113
Yes Austin, the clamps will handle a tube as large as 2.75" so it can bolt on to the factory roll bar in the rear.

How do I pair the remote?

Asked by: Jake0331
There's no need to pair the JBL STADIUM AMPLIFIED POWERSPORTS SOUNDBAR remote control since it's an RF remote. It will automatically work with the unit as long as the batteries are installed properly.

Will the remote work while clipped into the end of the unit. I'm mounting the sound bar on the back roll cage so the controls will be on the passenger side.

Asked by: toddlee99
Hi! Yes the remote control will work since it is uses Bluetooth connection. It controls the Bluetooth source that is playing through the soundbar.

I was hoping to add this to my boat audio system on my wake tower. I’m out of channels on my amp so I was looking for a sound bar that’s powered and runs off an RCA input from my head unit. Has anyone used it like this?

Asked by: Tbrazz21
You can definitely run this off to a head-unit. Just connect the source unit's RCA line outputs to the soundbar's (black) RCA audio input cable.

i am confused do you need a head unit (stereo) for this to work or can i just place music off my phone to it? also with the bluetooth capabilities does that mean the when playing music from the phone it doesnt have to be plugged into the unit? thanks
