ok i tried a whole bunch of stuff...receiver setup, testing with dvd..bla bla...still dead as a doornail. So i called axiom up and they had me run a few tests. They said run a dvd and plug one of the rca's into the sub..i got nothing. They also had me test the cable by licking the end while plugged into the sub...got nothing. They said it may be the cable...I went a bought another cable...still no sound with the new cable. Sooooo, they are shipping me a new sub. Thanks for the help...We will see what happens when i get the new sub...thanks again.
