Looking to pick up one of the powered SVS's between $500-$600 for an after christmas present based on all the information I've gathered on this forum. Just out of curiousity though when i hook my sub up to my reciever it requires just one subwoofer cable. When I look at the pictures of the BASH amp on the SVS I dont see this input I just see a left and right input? How would I go about hooking this up to my receiver? as i believe my reciever only has one subwoofer hookup. can anyone clarify or do i make no sense? Also what SVS do you recomend in that price range?
