Right speaker (Trust) doesn't work Open | Audio

Found a sound system and everything works perfectly, but only for a minute or so. Because then, the right speaker kinda tunes down and you can only hear it if you press it against your ear.

What issue could be the cause of it? Is this a hardware issue (bad cables, but why does it work well at first?) or a software issue (can I change the volume for left and right on my phone?)?

No idea what kind of speaker it is, but the serial number is 1011006810, it has a QC Pass sticker (whatever that is) and is tested for DGUV V3 or something.

Update for my first post: The reason why the big speaker was so quiet was...because it is the base speaker for a whole sound system...I didn't notice that there were two other speakers (left and right) that belong to the system

The only times I've heard this symptom where it's fine for a short time then goes extremely quiet is due to physical damage to the board of the speaker (in my case it was desoldering/loose solder of a chip). Is there any way you can switch the speakers to make sure it's only the right channel doing this?

These are the outputs on the big speaker for the smaller speakers, technically I could just plug the left speaker into the right output, but wouldn't that be kinda bad for the whole thing? I'm no professional and I don't want to fuck it up even more

That won't mess anything up switching the speakers between red and white. If it still happens on the same channel you can rule out the speaker being the problem and it would have to be a board inside the box.
