hey i have 2 hifonics hifi 1500.d i have the RCA split from the headunit. one amp seems to make a big diff when i turn up the Bass boost knob and the second amp really doesn't make a diff. the RCA's are split with a Y and 2 short cable are conceted from that to the Inputs of both amps. is it that the main amps settings are being transfured over to the second one so that if the first amps knob is all the way up then the second amp's knob will be he same? but if the first amps knob is down then the second amps knobs all the way up??26531500

or pull the remote from the amp and let and set the gains on both with a dmm. you cant run both thoughs amps like that with 1 knob.. not with out a maxxlink
