Plugging a Sub W/no Speaker Inputs into a Receiver W/no Sub Output

    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.

    It sounds like you'll need to convert the speaker level outputs into a line level that the sub will accept. There are lots of options to do that just be careful that you aren't sending more power than they're rated for.

    That receiver has a tape out, yes? Use that.

    Sounds like a plan.

    Thanks again.

    As it turns out, I had the necessary adapter to allow me to plug the sub into the tape monitor. Then I put on St. Saens' Organ Symphony. It shook things up very nicely, thank you.
