How to wire a TS12 sub woofer


Hi all,

I have just been given a Tannoy TS12 and I want to add it to my hifi system of a Rotel RA10 Rotel 980 BX and Tannoy M3's. The 980BX just has 2 outputs for speakers so I will have to combine the speaker wires of the Sub with a set of the speakers (does it matter which one) also where on the sub do I attach them?

Oh and is this a good idea
