do i use both subwoofer outs

[admin_exported]

I have a rxa 810 amp which has twin subwoofer output, should i use a splitter and one cable to my q7000 sub for better performance

No point -– both sub-outs are carrying the same signal, so a single cable from one of them to your sub will do just fine.

The L terminal should also be labelled LFE, connect it to that one.

Again no, as the two inputs on the sub will be commoned into a single mono amp.

Because a few subs work best when both left and right inputs are used.

Indeed.

When you common the sub inputs you get additional gain + 3dB is normal. Andrew is correct in saying that the sub inputs combine inside the sub so there is no point in feeding both inputs - unless you are short of level.
