Radio Wiring Harness - Wire Gauage
I own a PAC C2R-VW2 for my MK5:
I believe all the wires are of 18awg. My question is that, is 18awg enough for the power wires? Looking at those ampacity charts it looks like the maximum load of 18awg is 16amp for chassis wiring (well I am not even sure it falls into the chassis wiring category since air ventilation back in the dash isn't very good), but I would guess running at half of the maximum is what we would usually do?
I tried but failed to find the gauge number of other similar wiring harness. My amp is just a TDA7850, but my NUC can also draw as much as 65W. Will I run any risk if I just use the 18awg power wires? Or I am being too paranoid as many people install aftermarket radios with these wiring harness?
Will be very grateful if you can answer my questions.
