Connecting a subwoofer and bookshelf speakers to PC

[Jason Kandola]

hi there, currently I have the Logitech z623 and would like a better sound experience and need some recommendations and help. Could I use a lepy amplifier and control a powered subwoofer and passive speakers? I need a better understanding of hooking up passive speakers and a subwoofer to a computer.

Subwoofer

IF you plugged that in.. then you can directly plug into the sub. you can then just use normal speaker wires to bridge between the sub and amp ins to connect up the other speakers. JUST make sure you do not do it backwards.. like do not plug the OUT on the amp to the computer or you will cause damage. SO its like Computer out to Sub ins, and Sub In to amp In. then amp out to other speakers.. (or Computer to amp ins, amp ins to sub, and amp out to other speakers. being the sub already has its own amp just don't add more power
