I have a 20mm2 power cable (16mm2 = 6AWG, 25mm2 = 4AWG) I want to power about a total of 800W RMS. Can my cable handle that? or should I uppgrade to a bigger?
BTW, one Amp has 2x30A fuses and the other 1x40A so the total is 100A in fuses on my amps.
okok, how much more could the cable handle? At the moment I will have 800W RMS, but in the future I plan on getting another sub, and will then need another 400W RMS. Do I have to uppgrade the cable then? Got any guides where I can see how much diffrent cables can handle (Ampere/W RMS) ?
