Length of battery cable matters?

[QUOTE="Lasherž, post: 8712051, member: 679555"] Yeah, I mean I would cut it, but I'll never own a Tahoe. Looking again at the figures I think you're right about the voltage drop, my numbers were overly based on my 2 AWG OFC wire (which would give only .13V drop) so .3v is actually kind of a lot and presumably at 40A draw (near clipping on all channels for a class D amp @ 520W) it would go up to half a volt over just 10 feet. That's pretty substantial for not even factoring in the battery or alternator voltage drop. I wouldn't cry over .5V but it may be worth it if you've got a battery on its last leg and your voltage stays under 13.5V from the get-go to just chop it off and consider it better. [/QUOTE]
