What i ca i do my jbl bulse burnt?


There should be a short circuit inside its circuit board. You have to check the audio output circuit to get the fault, and to replace the damaged component/s. If you wish to get some details; check the site linked here. Pull up older posts.

The fuse keeps blowing as soon as i power up jbl pb 12


You have an overload in the power supply or main amp of the subwoofer, often caused by short circuited transistor. Check this out by putting an ohm meter probe to each of it's legs. If it acts like you were touching the probes together you have found a guilty part.

Bloon Fuses!


You don't need schematics to replace the fuses.
Open the speaker unit by unscrewing the back. The fuses are located near the on/off switch assembly. Replace them and screw the the unit back together.
To avoid blown fuses, try lowering the volume.
