I built a sub for my home theater. The amp I used is similar to this one "Dayton Audio SPA500 500W Subwoofer Plate Amplifier" from www.parts-express.com! . As you can see, it does not have speaker inputs. My ht receiver died. I decided not to replace it and got a sound bar instead. I would like to use this sub with my Marantz Twenty-six receiver, which has no sub output and only one set of speaker outputs. I am open to and would be grateful for any suggestions.
