Sub-woofer connection query

[marklaws]

I have an excellent 5.1 Surround Sound system, mainly all Jensen products. However, I cannot figure out the sub-woofer set-up. The lead from the receiver/amplifier has an thernet plug at one end (the amp end) and left and right plugs at the other end. As the sub-woofer foes not have a left and right, which of these two plugs should be inserted into which plug hole (L & R) on the back of the sub-woofer? Thanks.

Pictures and/or specific model numbers would help here.

Normally 5.1 surround receivers have bass management and direct the bass below the crossover frequency to its line level sub-woofer output. It should be a single output. It shouldn't be L & R. Maybe those leads are not the receiver's sub-woofer output.
