So after i find what speaker wires control the sub I connect it through the converter from there is were i am confused a bit. There are 4 lines (+,-,+,-) that can connect into the converter but then the out put is just a L and R RCA cable . how do I send the speaker single to all 3 amps? from the RCA Left and right cable?
