In the second week of December, it was, as always, cozy in the Watthok, the company was good, the freshmen were active and the music was booming! Although I (Jesse) also liked the music, I could no longer hear the very interesting conversations, because the speaker was close to my left ear. To solve this, Gideon, Tim and I decided to hang the speakers high. We had neatly disconnected everything, hung it on the existing screws, got coupling pieces, extended the cable and neatly reconnected it.

“Luckily we are from Watt and we can fix this” we thought to ourselves. So we got to work: take the subwoofer apart, replace the fuse, connect it, test it and again: quiet! 2:0. When we took the subwoofer apart again, we saw that a trace in the PCB had come loose, so after soldering it back together, connecting everything, and testing again…: still silent! 3:0.
This went on for a few times, until we decided to test the subwoofer separately from the rest, one by one we connected everything and YES! 6:1 “It works!” we shouted, but we cheered too soon. When we had screwed everything back together, the fuse decided to blow again (with a loud flash). 7:1. Finally, after a week of sogging, we won the competition! (in the meantime it was already 11:2). What was the problem, you ask? Apparently, if the cable from the speaker to the subwoofer is extended, this creates too much power in the PCB, causing the fuse to blow.
Moral of the story: never give up! (even though you can also buy the replacement for € 20 on Marktplaats).
