how many rca cables do i need?

[jsluss17 10+ year member]

my deck has 3 preouts front rear and sub. i'm planning on amping the front two speakers with a 4 channel amp and bridging it. my amp has 3 rca inputs one for channel A one for channel B and then an output. will i need a second rca cable for channel B also? and if i do can i just use the output on my sub amp and connect it to the input on my speaker amp?

How are you planning on bridging them? Bridging each speaker to its own channel or what? Why would you like to bridge them?

yeah im doing each speaker to each channel because the amp only puts out enough power to power 2 of them. or can i bridge both from one channel only? or is there any other way i can bridge it?

read your manual before you bridge, i know that some amps require an input in all 4 channels to achieve stereo, otherwise it will only play mono.

could always just run 4 separate, or just 2 of the channels.
