alright, i just got back from st. louis and i have been confused to in the few days i was up there. my family went on a little mini-vacation up there and i decided to go to any and every car audio stores i could find. well, when i told a particular salesman (at a respectable store, not best buy or circuit city) about my setup and future plans, he seemed to think he had a better idea. he suggested that since i have an alpine 7998 i should get a 4 chan. amp and not even use the passive x-overs that come with a comp set. he said i should run seperate channels to my tweets and mids. he refered to it as bi-wiring and he seemed to think that would give me the best results. can anybody help me out? thanks!!
