hi, I have a jbl gto75.4 i'm trying to configure it as 3 channel amplifier since i have only 2 channels going out of the head unit i have to connect 2 inputs of the 2 channels that bridged to subwoofer and one input of 2 channels that connected to speakers. But when i'm connecting all 3 inputs (right and left of bridged subwoofer and right of the speakers) as one RCA input the red protected led turns on..
Can someone please tell what i'm doing wrong here ?
