[QUOTE="........., post: 8864689, member: 690350"] Thing is I get multiple inputs stating different things. I have not worked with high current DC like this. I have however, worked in industry with high current, high voltage AC. Up to 1000hp 3 phase motors. But the wire in those situations is small compared to a car stereo. the 1/0 I have in my truck is twice the size as a 4160vac, 250hp motor. So right now I'm still trying to wrap my head around why I would need wire diameter big as a nickel for a few hundred amps. So at the moment I'm going to assume it's like in AC, where the larger higher voltage motors took smaller wire as opposed to the smaller hp motors that needed 4x the wire size. That being said, I feel that 2/0 will suffice for my setup. One run to the rear battery and from there to a fused distribution block then to the amp. Is there something I'm not seeing? If there is a good reason I should NOT, absolutely not use 2/0 please let me know before I order anything and waste my money. Otherwise I'm gonna go ahead and grab 30' of it and be done. FYI: I have a bad habit of overthinking things. [/QUOTE]
