I have 2 four channel amps, 6 preouts from the head unit the fronts and rears are on one amp i am trying to run 2 subs off of the other 4 channel amp, bridged, my question is what do I do with the head units sub out into the amp, rca splitters? Or can I take one lead ie. The red to channels 1&2 and the white to 3&4?????

splitters work.

some amps have RCA outputs for daisy-chaining signals.

many 4 channel amps have the ability to work with 2 inputs or 4 inputs.

My other amp is a jl e4300 with pre outs, same scenerio, one preout for 4 channels, (1&2, 3&4 bridged). Are the oreouts of either the other amp or head unit designated left and right?

yes, head unit preouts are designated left (white) and right (red). amp channels labeled 1, 2, 3, & 4 are usually grouped in pairs and within those pairs you can decide what you want for left and right. i typically use 1 and 3 for left, 2 and 4 for right, but you could reverse it and be fine as long as you were consistent with how you wire the outputs.

just run a left and right verification track at the end and use the balance and fader on the head unit to verify.
