JBL Car Audio & Video - Recent Questions, Troubleshooting & Support


Any speaker, if abused, can be blown. And if overdriven with dirty power at extreme levels it is not uncommon to burn out the voice coil. You might also want to check out the speaker surrounds. If they go, the speaker works but sounds lousy.

Localize the problem by hooking up two known good working speakers and see what happens. If they also do not work properly or sound like cr-p then the radio is at issue.

Bad or shorted voice coil on sub maybe. If you have two subs try them one at a time to see if it goes into protect mode. Whatever sub does it is bad.

It is very dependent on your vehicle and whether you are using the built-in amp of the head unit or a separate amp. Ideally, I would recommend a good 6.5" component set.
