I just bought a pair of M22 ti's and they sound great. Now I'm thinking of getting a subwoofer. I have an Adcom stereo amp. On the axiom web page it says to run the speaker cables from the amp to the subwoofer in, then run them out to your speakers. This may be a stupid question, but, does that mean the amp in the subwoofer is powering the bookshelf speakers?
