Negative effects to oversize in wiring?

Im just curious becuase i will soon be pushing 2200 w rms and i was going with 2 gauge but i figuered if it couldnt hurt maybe go larger for when i upgrade.

2200wrms and only 2 gauge? bigger wire ftw

winner winner chicken dinner . About the only drawbacks I'm aware of when using too large of wire //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Have to buy special tools to cut cleanly

obviously when there are less amps passing through wires a larger wire will provide more resistance. Once you are drawing 2 or 3 hundered DC amps through a wire you would probably have to use something like 4 or 5/0 awg to see any drops in voltage at the end. I would definitly use at least 1/0 awg for 2200 watts. when drawing high amps using smaller wire could generate heat in the wire and you may end up with melted sheaths or worse, your car on fire.

Or keep a redneck with good teeth around //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Really? I always thought the effect was the opposite.

a larger wire will provide less resistance. Once you are drawing 2 or 3 hundered DC amps through a wire you would probably have to use something like multiple runs 0 gauge to avoid any major drops in voltage at the end. I would definitly use at least 1/0 awg for 2200 watts. when drawing high amps using smaller wire could generate heat in the wire and you may end up with melted sheaths or worse, your car on fire.

Fixed...kinda.
