Sorry, I exagerated. The gauge will
affect the output, but i'm talking between 8 gauge and 4 gauge (the standard for most non-competitive systems). The output is going to be close, is what I meant to say. Only really noticeable when cranked. Sorry for not clarifying that.
If the distance from the battery to the amp is increased, wouldn't you want a lower gauge wire and not a HIGHER one. Remember, lower gauge allows for more current. Longer wire creates more resistance.
You already knew that, I was just correcting you.
