[QUOTE="ktennies, post: 8233848, member: 659894"] Like the title says, I'll be bridging my four channel amp into two channels to run my front components so I can get max power from the amp. The components have passive crossovers. There will be no rear fill. I've been reading online to understand how to run RCA cables to accomplish this while remaining in stereo. The most popular answer I see online is to only run the front RCAs and buy two Y-splitter cables and run the two left channels into the front left and right (so amp front = left) and run the two right channels into the rear left and right (so amp rear = right). The rear RCA outputs on the head unit would go unused. This is easy enough to understand. Questions: 1) If one had an extra RCA cable, would the outcome be different from the above answer if both front and rear RCAs were run from the head unit with the two left channels going into the front left and right (so amp front = left) and run the two right channels into the rear left and right (so amp rear = right)? I mean it would be the same difference because the head unit has already doubled the channels (y-split the channels) itself for front and rear, right? 2) Wouldn't using both front and rear preamp outputs result in increased voltage to the amp, or does a head unit's stated amp voltage refer to total preamp voltage of all preap outputs combined?
