Hey ever knowledgeable hi-fi forum people, I managed to get an eltax atomic 10.2 on the cheap but i'm not exactly sure how to hook it up to my amp (integrated stereo amp). The sub has speaker terminals and a line input. The terminals are labelled HF though?! I was advised to connect the amp to the speakers via the speaker terminals on the sub (the LF of the speakers)....is that the right way?
