Ive got a boston acoustics powered subwoofer for my home theater and am wondering what the left and right outputs that are on the back of it are for. The lfe comes from my receiver which i understand but what are the left and right outputs for? Do you get better bass output if you run 2 rca's into it or whats the deal? Also id like to get subwoofer usage while listening in stereo......how would i do that? I cant seem to find the right setting on my receiver either, its a pioneer elite sc-25 anybody who has any information would be very helpful in this matter. Thank-you!
