absolutely!! I agree with that 110%...but power and ground still need to be the same size.

yes for sure, its no different then when we were kids playing with batteries and light bulb and all that, now if we were to give the kid a 4000 watt light bulb and only enough 1/0 gauge for the positive side, you would totally melt the negative side of the cable running the 18 gauge :D ha ha

the main thing with the big 3 is decreasing resistance to your charging system and giving your amp the correct return sized ground cable up to the battery

ground isn't the return...electrons flow negative to positive...fun fact of the day

well, looks like I'm going through my car with more 0 AWG again! Can I run it beside the positive?

depending on the theory of electricity you go by, modern electricity it goes from negative to positive

No point of fusing the amp. If one thong I learned is if the amp wants to blow oh it's going to blow and there ain't a thing you can do to predict it or protect it from doing that!!!

Only fusing I would do is at the alt and before the battery bank

You guys are something else!! Lol... I must admit tho, I have learned alot in the last 1 hour reading this thread than what i THOUGHT i knew in the last 5 years! lol.. The great thing about SMD is that you learn ALOT from everybody! Its all about what you can learn and take that and teach someone else! I remember hooking up my 1st amp 20 years ago and i DIDNT have a fuse at the main batt! Came out and the whole damn car almost fried!! lol. My mom is STILL cursing me out!! lol. In the end, we all learn from each other and this tit for tat is just stupid! SMD for life!!

I have seen installs like that, no fuse, and the guy said he was tapping the positive and negative to make sparks, I was just appalled lol
