Powerful Performance Companion for Your Active Lifestyle

Legendary JBL pro and home audio performance is now available for the great outdoors. The new JBL STADIUM UB4100 AMPLIFIED Powersports Soundbar is designed for UTVs, boats, and other personal and family vehicles built for fun and recreation. Take the wheel or helm and experience the sound of powerful JBL rollicking sound. (Try 100dB at fifteen feet!) It’s also equipped with a super flexible mounting system that fits any size roll cage and will take a 10G shock and stay put. You can also separate the soundbar into two speaker towers to optimize sound quality for any installation. Bluetooth, 3.5mm, and RCA output jacks allow you and your friends to take turns streaming playlists. There’s a GoPro shoe for an action camera to share your finest moments – like how you look when you hit your first hole-in-one. With a glowing red LED output display and ambient lighting, you’re in the cockpit ready to do things you’ve never done before – be it on land, sea, or a long green fairway.


  • Full-range separable speaker system
  • Flexible placement
  • Detachable remote BT
  • Class D amplifier with multi-inputs
  • Party Mode
  • Outstanding display and appearance
  • Audio output
  • Power/protection LED
  • Micro USB

Full-Range Separable Speaker System

The high performance speaker array consists of a pair of 4" long excursion mid/woofers and one high output tweeter per channel. The STADIUM UB4100 can also be separated into two speaker towers, utilizing the optional JBL SK300 separation kit which includes a 9.8' (3m) bridge umbilical cable and rear and bottom filler plates.

Flexible Placement

A versatile mounting system with universal mounting clamps, inserts, and quick release brackets offers easy installation and multi-mounting options – that includes pontoon boats!

Detachable Remote BT

A detachable RF remote gives you full control over your music wherever you are without having to aim the remote at the Soundbar and worrying about the sunlight washing you out.

Class D Amplifier with Multi-Inputs

The high-efficiency Class D amplifier with 120Wrms per channel is equipped with Bluetooth, 3.5mm, and RCA inputs and includes intelligent priority switching, greatly simplifying the user interface by completely eliminating manual source selection. The 3.5mm jack overrides Bluetooth, which overrides the RCA inputs. Simple and efficient!

Party Mode

This provides simultaneous connection of up to three Bluetooth devices – while playing music from one device at a time. Audio will stream from the device most recently selected and pause other AVRCP-compatible devices. Share playlists with three of your closest friends.

Outstanding Display and Appearance

Aside from being an impressive looking product, the STADIUM UB4100 is also weatherproof with an IPx6 rating. A glowing red LED display across the front panel flashes in time with the music. And dual-level LED down lighting makes a perfect work light for reading maps or executing other on-the-move tasks.

Audio Output

Two channel full-range L & R outputs enable you to expand the sound system with additional components such as a powered subwoofer or amplifier.


LED Power/protection LED flashes when the amplifier shuts down due to overcurrent, overvolt, overtemp, or DC offset.

Micro USB

A micro USB connection is provided to future-proof the STADIUM UB4100 with software updates.

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!

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.

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.

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.

Great speaker has everything you would expect from JBL. Speaker gets very loud without distorting sound and the style is on point. My only recommendation would be different mounting brackets. These ones are very large and do not match the sleek style of the speaker but they do serve there purpose well when it comes to holding speaker onto bar.

Sent it back
I gave it a 3 only because the unit is just too bulky, we ended up returning it. Didn't get a chance to hear it. It be nice if jbl designed a sleek, slim soundbar. Always if we used the brackets provided, the bar hung too low. We have many jbl products, this one just didn't work for us.

Sounds great but limited mounting options
If you have a roof on your ride, the 4+ inch wide clamps it comes with is an real pain. I could not mount it on the front cross bar on my stock rzr xp4t. I can mount it on the middle cross bar, but the roof will rest on the clamps and leave about a 3/4" gap between the roof the cage at the that point and only rests on the cage at the front and rear cross bars. The videos I saw had different clamps (they specifically showed them off) then the ones that came with it.

Great Sounding
Pros.... Great sound and very clear. The sound can't be beat. I would recommend just for sound but not for size and configuration.

Cons... Hard to mount. Very big and doesn't mount to front bar of T4 so mounted in middle. Still not best spot. Brackets are too big and bulky. Hangs too low. We actually hit a bump and my friend busted her head on the unit. Trying to figure out a better spot for this. If we can get that figured out the unit will be awesome.

Do i need to buy any additional wiring to plug this up on my 2018 kawasaki teryx 4 LE ?
Kyle T on Apr 30, 2018
  This will wire to your existing head unit or external amplifier directly. All you might require is an extra length of conventional speaker wire.
Is it water proof ?
Kyle T on Apr 29, 2018
  This is not waterproof.
