were they working before you bought them?
have you done anything to cable connectors at the back of the speaker?
i ask because when i changed the terminals i didnt check to see if they were properly insulated from the plate they screw against,they weren't and it caused the speaker to stop working,when tested separately the drivers worked,might be worth a check.
