Hello,
the only way to get to the fuse:
you need to remove all the screws surrounding the amp on the back of the speaker. when removing the last screw be sure to hold the amp
in place because if you don't it will fall out towards you causing damage to you as well the screw hole.
disconnect the speaker connector. you need to press the latch on the side of the connector to release it from the base.
carefully remove the amp and lay it flat on a sturdy surface. don't lay it on something that can tear because the grill on the amp can damage cloth very easily.
If you look at the board closest to the edge you will see a fuse there as well as on the main board that is lying flat. check those fuses to see if they are burn marks on them. you should have 3 fuses to check. replace as needed with the correct ones. if you don't know which ones you need take them to an electronics store or auto store.
hope this helps.
