Hi, I had a home theatre system but the amp/receiver thing and the sub got damaged so I've had to replace them. I bought a Sony console and connected all the speakers PS3 etc to it, no problems. Been searching for a sub at a good price and after a couple months finally found a Wharfedale one on sale. Got it home, went to plug the little purple cable into it and found it only has the red/white sockets on the back. No idea if this is compatible with my head deck thingy? It says Vardus 8 Sub on the box. Receiver says STR-DH520 on the front. Any help would be appreciated.
