Subwoofer connection to older tube amp


I need to connect my Dominator 8 Sub to an Audio Research D-90 Amp and SP-12 Pre. The amp outputs only allow left and right bare wire speaker connections for different ohm ratings and I'll use the 8 ohm for main speakers.

Like most subs I'm afforded 2 pair of Left & Right Speaker Level inputs and 1 pair L&R Line(RCA plug) inputs and 1 pair L&R Line outputs.

Where would I hook the L/R from the amp to the sub? I want to use the set-up mostly for music but also for movies/DVD's.

I know it is and old post but I really want to know: does this dual speaker wire to sub work for tube amps?
It sounds great. Are the cables the same AWG? Or shall I use thiner cable for the sub?
