remote wires dont have as much current flowing as 1/0awg does, its only got maby .5-1.0 amps flowing threw it, its just enulf to tell it to cut on, will not make more power, or make it run more efficent with larger remote wire, kinda why on the back of the headunit u got the yellow thats like 12awg, ground thats like 12awg, red thats like 16awg and remote thats like 16-18, no need for bigger wires for only a small job, some amps that have high level inputs use the jolt or w/e the headunit gives it when it turns on to turn on the amp, they just need that lil bit of power to close the circuit to turn it on, hope that helps u out?
