One sub working.

I have had only one sub working the entire time. I have messed with the wires and can't figure out what is happening. When the white wire is plugged into the red the right side works. When it is plugged into the white the left side works. I have no knowledge about any of the audio wiring and what not. Any help???

How are the subs wired together ?

One of these on each side

Then ran to this

Sounds like your rca's might be going bad, you should try and change them to known good ones, or pull your stereo out and see if they unplugged or try new ones
