Bring JBL sound to your outdoor life

Awesome JBL sound isn't just for the great indoors anymore. This amplified marine soundbar lets you bring JBL excellence to your boat, ATV, or even golf cart. Bluetooth® connectivity, plus 3.5mm and RCA inputs, lets you stream all kinds of music, while the built-in amp pumps out 160 watts of power for awesome sound.

JBL UB4100BLK Amplified Powersports Soundbar

Ideal for ATVs, UTVs, boats, and golf carts

Powerful speakers are just the start

This soundbar features four long-excursion 4" mid/woofers and a pair of high-output tweeters, so there's plenty of volume on tap. If that's not enough, a set of preamp outputs lets you add additional amps and speakers or even a subwoofer to your system.

Cooler still, you can also use the JBL SK300 separation kit to split the unit into two speaker towers. That kit (sold separately) includes a 9.8' umbilical cable that connects the two speakers, along with rear and bottom filler plates.

Compact, powerful Class D amplifier

The ultra-efficient Class D amp kicks out 80 watts RMS to each channel, and includes intelligent priority switching so it's easy to connect and enjoy your various devices. The 3.5mm jack overrides the Bluetooth, which in turn overrides the RCA inputs. That simplicity will come in very handy on the water or on the trail.

Installation is easy

The JBL UB4100 comes with a versatile mounting system that allows you to install it on a vast variety of roll bars, wake towers, and cages. The system includes universal mounting clamps, inserts, and quick-release brackets. It's easy to install and tough enough to withstand a 10g shock.

The detachable RF remote lets you control your music from wherever you are, and there's even a GoPro shoe so you can mount your action camera and capture all your biggest moments.

Have a party

With "Party Mode," you can simultaneously connect up to three Bluetooth devices to this JBL and share DJ duties with your friends, streaming from the device most recently selected while you pause the other two.

Looks good and built to last

The JBL UB4100 is made for the outdoors, with an IPx6 weatherproof and splashproof rating. It'll stand up to whatever you can dish out and keep the music going the whole time.

You'll also appreciate smart features like a glowing red front-panel LED display that flashes in time with the music and a dual-level LED light that'll be a big help when you need to consult a map. This soundbar is even future-proofed, with a micro USB connection that you can use to install JBL software updates.

    I have this on my yahama yxz 1000r and love it. I have it paired to my JL Audio mm100s headunit and also have Rockford lower front pods with Rockford punch speakers in them and a Rockford sub box and 10" Rockford sub under my seat. The jbl soundbar has its own amp built in and just screams but all soundbars do that, the difference in the JBL vs wetsound is that the JBL is clean and clear when loud where others are not. I also have a JBL amp running my front speakers and my sub. JbL is harmond and if you know anything about sound they are the best of the best when it comes to design and performance.

    Pros:

    Cons:

    Stay far away! Bracket makes it hang really low. Speaker or speakers sound terrible after only 2 rides. Wish I did not wait to installed because I am now out of the return window.

    Pros: easy to install

    Cons: Lasted two rides.Sounds terrible now

    Solid product with great sound

    Jordan from West Jordan, UT on 3/22/2018

    Great Volume Quality, seems we'll built. I purchased this one over others because it has RCA inputs and a remote amp turn on wire which will be really nice when mounted on my wake tower. The supplied cables are all much too short for a boat application so do know that. A lot of people have commented on the mounting brackets being big, and yes they are slightly large, but not larger than the should be for the features that they offer like swiveling and stuff.. overall very happy with how this sound bar looks and sounds. Hopefully it functions how I want it to when I get it all hooked up.

    Pros: RCA input, larger speakers, Lights, remote control, quality

    Cons: Mounting brackets do cause it to hang a little low, but it does so for a valuable swivel feature.

    I'm really enjoying the JBL Ub4100 soundbar! What a difference in customer service from past experiences with other companies. It's been wonderful, from my initial contact with Crutchfield while investigating soundbars through the purchase and installation. It felt as if I had a personal assistant throughout the process. I'm sure to check out Crutchfield before making purchases in the future. Thanks again team Crutchfield!

    Q
    Can you connect this device to a head unit or can it only be controlled by the remote and buttons on the device?

    Hi David! You can connect this sound bar to a head unit! If you're using an aftermarket head unit that has RCA outputs, just connect the source unit's RCA outs, to the soundbar's RCA audio input cables. If your stereo does not have RCA outputs, you'll receive in the box a bare wire-to-RCA adapter to connect the source unit's speaker wires to the soundbar's audio input cable. If you're going to be ordering this sounbar, our tech crew will be happy to walk you through any processes of connection when you start your install!
