Resurrect weird version of Z-5500

Hi I have an OLD set of Logitech Z-5500 speakers where its just not functioning anymore. It's the RCA version with a weird PID of 10003301-0445R. I've been searching for a way to resurrect the sub for my own use but I can't find any solutions anywhere. I don't want it to end up in a landfill.

I've bought an adapter meant for PIDS between R200-R635, but the sub just booms and buzzes when I connect it. Mine is obviously wired differently.

I'm not super knowledgeable about hacking electronics, but I have access to tools if I could just figure out what to do. Can anyone help me?
