Ah yes. How I do miss those electrical engineering classes. :biggrin: :tongue:Rick W said:Let's be realistic here! A 1000W amp will not melt 8awg wire. You may have too much voltage drop across that run, but it definitely won't melt.
If you want to use some basic theory here, you'll need to understand the overall resistance of your power feeds (and yes the feed going to ground is just as important). Most wires have a spec for ohms/foot. Once you know that, you can use the formulae to determine your voltage drop:
P = I*I/R = I*V = V*R*V
V = I/R
Alternatively, you can measure the voltage drop across your amp underload.
Most amps have a spec for voltage operating range. Your goal with the above is to make sure you do not fall below this spec.
Ok, now that I know what an ohm is, could someone tell me what a volt is???Avenger said:Hey!!! WHAT'S WRONG WITH 4 GAGUE????
BTW, I'm an electronics technician and I find someone asking what an ohm is is disgusting!
