If I use a .35 cable for power and a .10 for ground... I am missing actual power usage or ... ?
if you use multiple grounds, then you're going to have ground loop.. whining noises, so to speak. You could make the install easier by putting a non-fused block for grounds (this is what I do) and have one large ground wire at the other end.
Now, I assume your .35 and .10 is in inches. Whatever it is, you have to realise, just as in a car, you'll get full performance if the engine can breathe easier. How? Modify intakes and exhaust.
Now, compare that to electric. You gotta make sure enough electricity is going out, as much as it is coming in. That's why people will use (+) 0.35 and (-) 0.35. In fact, your GROUND(-) wire can be bigger. No good if the positive (+) wire is larger. Well, that's what I've been led to believe.
example:
For positive:
Batt -->ANL fuse--------------> fused distro block--------->amps
batt to ANL = 0.35
ANL to distro block = 0.35
Distro block to amps = 0.10
For negative:
amps------->block------->car chassis(body)
amps to block = 0.10
block to chassis = 0.35
