A friend of mine was just given the following Altec Lansing speakers for his PC. 2 x ACS410 2 x ACS41 ASC251 sub The 410's are powered (somehow) by the sub and the 41's are passive connecting to the 410's by 5 pin din. Does anyone own any of the above? If so please tell me how the heck to connect them all together! He bought them round to me last night and i'm baffled! Cheers Taz.
