Axiom Home Page Forums General Discussion Home Theater Subwoofer cables

I have an EP350 sub on order and I'm trying to buy the cables now. Question: What kind of cable do I need for the 12v trigger? Nobody seems to sell such a cable. I have found single (Mono) 3.5mm audio cables (rare breed) but I don't know if the wire gauge is big enough. How much current is actually flowing or is it just a voltage signal level?

Also, how important is the shielding on the Coax/RCA audio cable?

Thanks in advance
