So my birthday is coming up, and I got a Yamaha YST-SW012 8" 100 Watt subwoofer today. The cable for it (I'm not familiar with what it's called) is shaped like a single RCA at each end. The problem is, on my monitors, the output to sub jack is auxiliary (1/8 inch). I checked some stores for a hybrid cable or adapter and had no luck. Does anyone know where to find a cord like this? I've already tried the RCA (w/ red and white plugs) to AUX, and that didn't work. Any help would be greatly appreciated!

Okay, (sorry for bad quality pictures) so the bulky one that resembles an RCA end is for the sub, it's like that on both sides. I need a cord that has that on one end and the auxiliary (1/8 inch) head on the other end. The output to sub on the speaker is a 1/8 inch jack. I can't seem to find the right cord, all that's coming up is regular RCA (with a double end), and that won't work.

The cable is mono, so if you connect to the left output solely, it should work.

ion, I tried that originally and it didn't work. But, after adjusting the aux end more in the jack, it worked. Whoops, lol.
