Powered Speakers / Subwoofer Connection Question

[dcx4610]

Quite a simple question but hopefully someone can answer and provide some insight.

I recently purchased a 2nd SVS PB-1000 Pro subwoofer to use on my PC/gaming/music computer and the question I have is related to how to connect the subwoofer. Single input or dual?

I have powered speakers (Audioengine A2+) and since I'm not using a receiver in this setup, my question comes down to the LFE/RCA inputs on the subwoofer.

Right now, I have a single subwofer cable coming from the right output of the speaker going to the right/LFE input on the subwoofer.

Since I don't have a receiver on the PC and it's just a stereo setup, would I gain any benefit or would it be more proper to have RCA cables going to both the left and right outputs on the speaker and left and right inputs into the subwoofer? Does a single subwoofer cable make any difference versus a stereo cable in a stereo setup?

Hopefully that makes sense.... Thanks.
