why multiple runs of power/ground cables?
I am confused as to the logic behind this. I know alot of people are doing it, but why? especially with smaller cables(ie 4 and 2 gauge). the way I see it, four runs or 1 or 0 gauge is overkill. a battery can only produce so much electricity, and cables aren't 100 % efficiant, so if you add more cables, doesn't this lead to more loss of power? also if someone is running 4 runs of 4 gauge, wouldn't it make sense to run 2 runs of 2 gauge instead, or perhaps a single run of 0? I just don't see how running more cable is more efficiant than running less cable, especially in a 1 amp, 1 battery setup. if someone could clear this up for me it would be great.

u get more current faster from battery to amp

YULI STop Lying, ITs so all you spl guys' cars stay on the ground when the bass hits REALLY hard!! lol.. What Yuli says is right! lol
|
it's like 4 taps instead of one in your sink
sure it's technically less efficient (more loss then with a single tap) if the water pressure is there (or in this case hard amps) then the sink will fill faster then with one tap it all depends on what your doing I'd run multiple lruns for burping purposes, but my daily sq ride I'm not going to put more then one 0g run in |
ILL ADD A QUESTION TO THIS ONE ... at what point do you know you need multiple runs ? would it make a big difference on my two kicker L-5's and my 1000 watt rms massive audio amp ?
|
u've put enough when you stop gaining spl.
|
hmm, I guess I need more wire :P ALOT :P
|
Yuli is right, more parallel runs reduces system resistance and opens more lane of traffic flow for electrons, not terribly efficient but fractions of db's matter
|
The ESR (or equivalent Series Resistance) of the battery is rpetty easy to find out... take the voltage, divide by the cranking amps (so say 12 volts / 800 amps = 0.015 ohms) a run of 1/0 might have a resistance of .02 ohms... which has cut your available current by over half, 2 runs makes the resistance of the wire .01 ohms, which is better, so multiple runs helps your batter work harder
|
sounds like a whole lot of fun i know a bit about audio but had no clue that would make a difference i guess im gonna have to get a better amp and battery and run more wires and see if i can upper my 140.7 lmao so sad:smilie_da
