Speakers have stopped working, fully plugged in, was working yesterday and has worked for the past few years. Stopped working today. Nothing wrong with drivers or anything, they should be working normally but for some reason they arent working.

slice open a full potato and smear it on your windows

From your question it is understood that the speakers you were using was fully charged and it was working best for 1 hour completely and suddenly it has been stopped and seems to be totally dead. To help you, it is recommended to take the speaker charger and charge the speaker once again and after sometime check if the speaker turns ON working.
If issue persists, it is recommended to replace the speaker if it is in warranty or ask for repairing the speaker.

Try unplugging the power cord from the machine, let it set for a few minutes and try plugging in again. Sometimes this will reset the machine.

Here are other postings on Fixya that sound similar to your problem:

LAN PORTS ARE BAD SEEMS TO BE.

This really sounds like a wiring problem. I would start from scratch, seeing as how it will be difficult to find the issue you describe. Also, if you can, solder your connections to the radio. If you used crimp butts they may not have been tight enough and vibrated loose with use of the boat. Hope this helps

If it is still under warranty, take it back and get it replaced!!!!!!!!!

Is it getting power?

Check your computer's plugged in devices (from device manager) to see if you computer can see your speakers plugged in. If they are, then try updating/installing the latest drivers. If nothing works, your speakers have become faulty. Try checking on a different computer, and if nothing works. Contact your vendor.
