[QUOTE="DRBOOM, post: 8765411, member: 676005"] With DC power; more efficient wire is better, but not necessary if your battery is close to the amplifier(s). Nevertheless, you can always do the 'over-kill, and it will not let power sag over the distance. Regardless, of you running 0,1,2,4 gauge, your amplifier will only draw the maximum amp that it is rated for. That is why proper system planning is needed so correct power supply is supplied to your amps, not the other way around. With car audio, thicker wire is definately better, if you have the funds, but if you follow the amps power ratings requirements, then you will not notice much difference. Only other factor is to check your electrical connections all the way to your amps every six months as they can get loose over time (not that I am saying it does) but a good precaution. [/QUOTE]
