What to do if JBL BASSPRO Subwoofer output gets louder when the head-unit balance is adjusted to L or R?
If the JBL Subwoofer output gets louder when the head-unit balance is adjusted to L or R, and you are using a speaker-level connection, it is likely that one of the speaker connections is reversed (+/–). Reverse one channel to correct this.
What to do if JBL Subwoofer POWER LED is not lit?
If the POWER LED on your JBL Subwoofer is not lit, it could be due to several reasons. First, the fuse might be blown and needs replacement, so replace the fuse. Second, the head unit might not be functioning properly, so check head unit functionality. Finally, inspect the remote turn-on, power, and ground connections.
What to do if JBL BASSPRO POWER LED is lit but there is no bass?
If the POWER LED is lit on your JBL Subwoofer but there is no bass, first check the connections, since the inputs may not be connected. Also, adjust the head-unit controls to feed audio signals to BassPro, as the head-unit fader controls may not be set properly. Finally, adjust the GAIN control setting, as it may be incorrect.
Why JBL BASSPRO Subwoofer POWER LED remains ON after system is turned off?
If the POWER LED remains ON on your JBL Subwoofer after the system is turned off, it may be because speaker-level connections have a five minute turn-off delay. Check the unit at a later time.
Why JBL BASSPRO output sounds muddy or distorted?
Muddy or distorted sound from your JBL Subwoofer can occur if the GAIN is set too high. Try lowering the GAIN setting. It may also happen if the bass level is set too high on your head unit, so try lowering the bass level on the head unit. If the head unit output is distorted or blown, it is recommended to consult your authorized JBL car audio dealer.
