I need some help, I have these 2 speakers with a base cannon, I am also using HDMI for video and A/V cables for audio. I have the red and yellow A/V cables hooked up to a 3.5mm stereo jack to 2 rca jack. I have the red in the left rca jack, and the yellow in the right. If it is like this the left one works and the right one doesn't, then if I reverse them the right one works and the left one doesn't. Does anyone know how to fix this?
