I recently purchased a full HT setup at a yard sale for $100. It included two Monitor 70's, CS20, 2 Bose 301 series V, and a PSW202 along with a Yamaha RX-V371. Unfortunately the PSW202 is not working. I have a sony DAV-FX500 system I used to use. I had the idea of using this along with the subwoofer that came with it. I don't want to spend anymore money right now on it. Could I use the subwoofer out on my yamaha to feed the DAV-FX500 with the line input to utilize the subwoofer?
