[QUOTE="ktennies, post: 8234229, member: 659894"] The speaker amp is a JBL GT5-A604. There is no bridge switch. I'm just going to use y-splitters with an RCA cable from the front outputs on the head unit and leave the rear output alone. I'll send both (front) left signals to the front RCA inputs on the amp and both (front) right signals to the rear RCA inputs on the amp. The left components will go to the amp's front outputs bridged and the rights will go to the rear outputs bridged. I was thinking this might result in preamp sound quality loss of four volts down to two volts from the head unit, but I'm reading that the y-splitters are creating a parallel circuit and will not result in voltage loss except miniscule amounts. One more question: Since I'm only going to be running preamp input from the head unit's front and subwoofer preamps (to different amp for subs) with the rear preamps being unused, should I adjust the head unit's fader all the way to the front before setting the gains on my amps?
