hey guys. new to the board and was directed here for help with my problem. i just bought the sony sawx700 and i got it home and nothing. i plugged it in. powered down my receiver and then powered everything on and no sound. my old sub works fine but nothing from the sony. its a kenwood receiver. i already talked with the sony online help but they didnt help. they said to try a new cable. why would a cable matter. worked on the old not the new? oh well. thanks for any help .
