I have a Pioneer VSX-D507S Receiver and 2 different pairs of speakers (for front and rear) and a center channel speaker. I recently bought Pioneer's HTP-200SW subwoofer. For some pictures and a little bit of information about the sub visit ebay, item #3043067790. I can't find any other info. on the internet about this sub (maybe from a package?) and it did not come with a manual. I need help with setting it up. I tried running the front speakers through the sub (see the ebay auction pictures for the connectors that I ran them through) but that did not give me much bass, maybe just my imagintaion that there was any bass coming out at all. Any advice in the best way to set this sub up? Thanks!
