Please disregard my previous post. Tying the two inputs to the subwoofer together is entirely different from tying the two outputs from the audio system together.I don't think you would want to tie both outputs from you audio system together. That would end up putting the left and right speakers together and you might also blow out the left and right power amplifiers in your audio system. Tying the two speakers leads together would also lead to cancellation of some signals. That would make your left and right speakers sound bad and the subwoofer would also sound bad.
