the 3.5mm lines went in my PC sound card to make sound**

Answer 1

For a proper setup, you need to connect TV SUB-out (RCA) to your active sub-woofer R/L-in (RCA). But I don't think your TV has a SUB-out. So you need either an AV receiver or an Equaliser( with build-in SUB-out port) connecting your TV and active SUB.

note: The picture looks like it's an active speaker not a sub-woofer ^^

Answer 2

You won't be able to do this without a receiver!

You will not want to send a full level signal to that sub as using the set up  would mean your regular speakers would not work.

You need a device to down mixing and level control, case in point a receiver.
