No sound out of subwoofer?
My receiver is a Optimus STAV-3670, and my subwoofer is a 10" Powered Optimus PRO SW-10P. Both of these items are old (1996+). I connect the subwoofer to my receiver through the Low Level Input on the back of the subwoofer, by using a RCA to Phono adapter. The phono end goes to my Subwoofer Pre-Out Jack, while the RCA goes into the Low Level Input, which are Red and White jacks (L/R). Whenever I play music, no sound comes out of my subwoofer, only my two speakers. Any help on how to fix this problem would be great. Thanks.
