Likely your amp has crapped out.
You can use almost any old speaker to try on the amp -
including some from a store with a return policy. Conversely, you could buy a cheap receiver, and gently turn up the power and see if you fried the speakers too.
Assuming you check the store's return policy is for cash.
If you have no test equipment at all, and don't know anyone with some, the only thing you can try is to gently try the speakers or the amp with another amp or speaker, respectively.
I'd try to find some help locally... other hobbyists or a local hifi store...
