Bose 3-2-1 speakers w/ regular receiver?

I've got an existing 3-2-1 setup and the main unit is almost dead. The speakers and sub are just fine. I was wondering if anyone has a solution to hook their non-standard speaker connectors to a normal receiver. I don't have the $$$ right now to buy all new speakers, etc., so just want to see if I can work w/ what I have.

any insight would be appreciated, I couldn't find much using search.

It's well out of warranty. This is the original 3-2-1 system. Just wondering if there's some type of connector that will adapt to a regular receiver.
