just wondering what would be the best way to hook up sub amps if you head unit only has one set of sub pre outs. i was thinking about just doing a set of y rca connectors out then run them in to a line driver . but the other day i was talking to my friend about it and he said to just the rca cable i have in all ready and then do y cables in to the amp . so i asked him what about the the pre amp line driver and he told me i didn't need it .so i said what about the pre amp line voltage after that he was like totally lost so i figured i ask hear and see if some one can put me on the right path of how to do this .the head unit is the one in my sig witch is a pioneer 1900 mp and the amp is going to be another one like what i have already witch is a pioneer 760 watt max
