I just purchased SVS PB 2000 Sub woofer. it arrived yesterday from Delhi to Bhopal in proper packing. However i have spent full day trying to set it up but there is no sound from it. The dealer says that it send it after testing - Denny from Bass N Treble Delhi. when i put my old sub woofer through the same connection there is no problem. Power light is showing so there is no power problem. Any suggestions.
