I just picked one of these units up at a great price and plugged it into my Yamaha RX-V1400 with an RCA line, giddy with the anticipation of hearing thunderous bass. Alas, I have not heard a single sound being emitted from this monster. Has anybody else out there had any experience, good or bad with this unit? Please describe how you've got this Sub wired and set up for optimal performance for both music and video. Thanks!
