well I was beginning to build a home theater set up that's why I bought the sub, I've got a Toshiba Dvd, Pioneer vsx, some Jbl's, various Bose, and a pair of Rf3's. I tried every thing I know to hook it up, made sure the settings in my receiver were set right, I even tried hooking speaker wire to the terminals on the sub to my main term. on my receiver and there was no sound at all, I tried the one jack from output of the receiver, I tried the y splice, changed the crossover settings, set the rec. for small speakers, nothing. Ultimate Electronics said that I could bring it in and they would test it for free but that's a 2 hr drive, and I don't know what they could do that I didn't.
