How To

The Boombox 2 features the same battery capacity as the first generation Boombox. The Boombox 2 battery specs have recently been changed in measurement specifications but still provides up to 24 hours of audio playback.

Many Harman Kardon, JBL and AKG products run on rechargeable batteries. In most cases, these batteries will provide years of excellent service and keep the music playing for many hours.

WARNING – the rechargeable batteries inside our products are not user-serviceable. Please do not attempt to open the product or replace the battery. Doing so will void your warranty.

Battery issues fall into three categories:

• Your speaker or headphones run out of power after only a short time.

• The speaker will not play at all because the battery will not hold a charge.

• When you plug in the cable to charge your speaker, sometimes it charges and sometimes it does not- the red charging LED or other indicator might not come on.

  Here are some things to try that often fix these issues.

1. It could be as simple as a bad USB charging cable. If you have other charging cables, give them a try. (Be sure that the cable has the same type of connector as the original one that came with your product.)

2. Same for the charger- if your product charges by USB, try a different USB charger. Be sure that it is rated at least 2.0a (2 amps) output.

3. Try other electrical outlets at your location to be certain it is not a local wiring issue.

4. Charge the product overnight for at least 8 hours.

5. When you plug the charging cable into the speaker or headphones, is the connector stable, or can it be wiggled around? If it can be wiggled, this could indicate that the charging port has been damaged or come loose. Sometimes wiggling the connection restores charging power.

IMPORTANT: Some products such as Xtreme, Xtreme 2, Boombox, Partybox 100 & 300, GO+Play and the Onyx Studio series do not use USB charging. Instead, they have a specialized charger. Do not attempt to charge these products with other cables or chargers.

If none of these fixes the issue, it could be that the battery has died or is losing its capacity, or that the charging connector on your speaker is damaged. Please contact us so we can assist you. Be sure to mention that you have tried the steps in this Battery & Charging FAQ so that our agents do not ask you to repeat these steps.

Installation of a powered subwoofer/speaker in an automobile requires specific knowledge and experience.  If you’ve read the manual and do not feel comfortable performing the installation and setup yourself, we recommend that installation be carried out at a specialized center by a professional.
 

The BASSPRO GO uses the original Connect feature.  It is not compatible with devices using the Connect+ or PartyBoost feature.  You can connect up to two BASSPRO GO speakers to each other using Connect, or you can connect a single BASSPRO GO to other JBL speakers that have the same Connect feature, like the Xtreme, Charge 3, Flip 3, and Pulse 2.
 

The BASSPRO GO receives is power ONLY from the harness that is connected to the car battery.  When connected to the harness, the car battery will charge the internal battery so that it is ready to be used as a portable the next time you need it.

When removed from the harness, the full-range portable speaker runs on the internal battery.  It cannot be charged via either of the USB (A or C) jacks.  It will be charged the next time it is connected to the harness in the vehicle.
 

A dedicated bass boost button located on the RIGHT ear cup on the CLUB 950NC & 700BT increases low-end frequencies of 5-6 dB adding a kick to your favorite tracks.

The Mute+ATMOS combination button press to determine the Battery Status was originally designed for production line testing, not for consumer usage.  We determined that this testing method was inaccurate and began testing using specialized external equipment.  As of Software Version V21.13.11.80, the ability to check Battery Status inaccurately has been removed.

When charging the satellite speakers you can be confident that the Battery Status is 100% when the LED indicator goes  out.  As well, when the LED begins blinking red, you are at 20% and should recharge or plug in your speakers.
