JBL Stadium Amplified Powersports Soundbar is rated 4.2 out of 5 by 6.
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 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.

Rated 3 out of 5 by from 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.

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.

I'm considering using this for my out door bar/deck. What's the smallest battery you would recommend for this use only? 

Asked by: Jay Molina
You really should not use a battery, as you will not have an easy way to charge it. Your best bet is to use a 12 volt power supply that you can plug into your electricity. Be sure that this power supply can support 40 amps of current.

My question is about the rf remote being able to get wet..The last time I asked you quoted me that the Soundbar is weatherproof. I understand this from the instruction manual but the instruction manual says nothing about whether the remote can get wet .?

Asked by: Ron A
While the soundbar can get wet since it's an IPX6 , since it's not totally waterproof,overexposure to water can cause damage to the sound or remote functions. If this does not answer your question ,please submit a case request at www.jbl.com/support-contact.html and the Customer Service team will be more than happy to further assist you.

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

Is the remote waterproof.??

Asked by: Ron A
The Stadium UB4100 Soundbar is weather proof IPx6 which protects it from water from any angle but not completely waterproof as it can't be immersed in water.
