A friend of a relative asked me if I wanted some speakers. I said sure. I thought he meant some computer/ipod/generic speakers... But I got these... Except... I have no idea what to do with them, everything about these speakers is proprietary. I have everything, the cables , the remote, the sub. But no receiver. Apparently he had some issues with the receiver, so after calling Bose, they sent him a whole new system instead of a replacement. But all he wanted was a new receiver. He called Bose about it, but they didn't want anything back.
