Hey,
Trying to figure out how to wire my head unit, 5 channel amp to my sub and 4 speakers.
What wires connect the head unit and amp together? Just the blue power feed wire? Or do I use the Line Out Front and Line Out Rear pluggins as well from the head unit to the amp?

The blue wire is the remote wire and you'll have to have rca for every channel

#

You'll have to run the power and ground wires to the amp still

The remote can be on either side because it's just a power on signal for the amp

Right, it’s not enough current for interference just gotta keep power away from RCA. Good clarification
