I want run this amp in 3 channel mode(1/2 to front components, 3/4 to sub), I would like to use 1 set RCA cable instead of addtional RCA and Y adapter, the mannual says the amp will sum the signal and do the low pass for me. Which way would be better? My Hu does have sub preout though. if both method work the same why should i bother with the Y adapter? What will be the difference?
