How to check wetsounds fuses?

[CLBeerbower]

Team quick question. 2021 212XD with wetsounds system. Sub is not working. Checked and verified that the zone is turned up. Also checked stern controls in case that was an issue. Rest of speakers work fine. Tried to remove the 40 amp fuses and could not get them out. Removed small black screw between them. Don’t want to break anything. Sure I am missing something as there is no way these things should be so hard to remove. Thanks for the ideas

Fuse won’t be the issue. Unplug the sub and check resistance at the terminals.

ok, so check the ohms at the sub? Are these things prone to failure?

Just checked and it is 4.2 ohms. Any other ideas?

check AC voltage out of amp next (sub channels). If you get voltage then check continuity between wires at amp and wires at sub.
