Onkyo TX-NR616 subwoofer setup

Trying to setup this av amp with a Vibe Alpha I subwoofer. The AV amp has a purple subwoofer pre-out and purple line in connections and the subwoofer has red and white L/R RCA connections. Any idea how I should connect these up properly? Connections hopefully illustrated below:

Try a simple twin phono lead and connect both purple outputs to the sub L/R inputs.

My onkyo is the same and I have two subs, one connected to each output but at the sub end I am using a two-to-one Y adaptors so I can use both inputs.

The purple outputs are a paralleled.

OK thanks for reply which is much appreciated; I understood that as an option but was confused/perturbed because on the Onkyo amp, one purple plug is "subwoofer out" and one is a purple "subwoofer line in" rather than simple L/R connections. I'm still not sure this is optimal connection? When you say "connected to each output" one of them is in fact an input?

You've lost me on both of those.
There are two purple phono sockets for two subwoofers, and the sockets beside those are Line Out for Zone 2.
Subwoofers usually take just the one phono input, but you can connect both to your two if you like.
Or do as Dave does for each of his two subwoofers, and split one at the sub end.

sorry to be obtuse - I understand that most subwoofers have only one input (and my amp has a purple line out to the subwoofer) ... the point that I'm trying to make is that my Vibe subwoofer has TWO inputs, ie L/R RCA inputs. Do I take one lead from the amp subwoofer out and split it as it joins the L/R inputs on the subwoofer? Thanks for your patience.

Maybe this would be better off in the subwoofers forum... thread moved

Just use the left/white input on the subwoofer. It will work fine.

I have a Subwoofer Out on my amp thing and I just connected a single, one-plug phono lead from it to just one of the inputs on the sub, either one of the Red or White (L or R) plugs I can't remember.

Works fine!

If you only have one sub use a single cable from one 2ub output on the amp and connect into the fet(white) input of the sub,
some subs have a slight boost in output if you connect both left and red inputs, you can so this via running 2 cables from the amp to the sub or you can run a single and by a y splitter.
