A STupid question!
 

Is It common when changing power wires to gain significant amounts? Only reason I ask, I had 2ga power wire in before,Didn't change a thing or settings on my amp or deck. I simple changed out to 0ga and added a 2nd run(1 positive and 1 negetive), went started up my car and at the same volume levels with my bass knob at full, I had to turn my amp down! Is this normal? I had a very good ground before, just wondering if 0ga makes that big of a difference? Its not like I added a few grams of magic dust to anything lol....Any feedback on this topic will be greatly appreciated.

put it on the meter

A 1.5V drop will probably be audible with an unregulated amp....

based on the resistance per foot I figure you could gain a maximum of 4db going from 2awg to 0awg...

dont know bout meter wise wayne but when i went from 2 to 0 I noticed a big difference in gain too

I noticed a gain when switching the wire, i havent metered it yet either.

Larger wire tends to remove the bottle neck. More unrestricted voltage = more out put ect. Would you rather breath out of say 1 straw or a garden hose, then why. Same basic principal here. Metering will take the guess work out if it's truly louder. In any changing we ALLWAYS get a starting point with a meter. Kinda like a reference for the day/ line in the sand.

I turned my gains DOWN and my setup still seems louder !! oh well, I guess clamping it is the only true way to find out right? Thank you all for your input!! And making me feel like im not on Crack anymore

Well your still on crack :p

When it comes to power/ground wire.. the more the better :)

Yes I know the more the better :D less resistance, better delivery overall of power, Just didn't think that it would change this much!! Thanks again everyone! and STeve, I stopped doing/giving off crack for a few months now :P hahahha(when Ifound my belt)
