with all the hype about large guage power wire i have a few questions.

tell me why i would need heavy guage power wire

tell me why i should switch from 8 guage to 4 guage

if i'm not blowing 40a fuses then in reality the 4 would be a waste, right

how many have really checked the amps while running your system

40 amps is alot of power, my home theatre is only on a 15 amp breaker.


just some good answers would help
