I Have Two Subwoofers; What Inputs Should I Use?

Sometimes it can be a little confusing choosing the right inputs when you have two subwoofers. Since there are two inputs, it seems logical to use "input 1" on one subwoofer and "input 2" on the second subwoofer. When using the default settings, this is actually not correct and you should use "input 1" on both subwoofers.
