4 gauge wire enough

Are we sure we aren't buying into marketing hype with these wires?

Here's a link I found on CAF to necessary wire sizes. Wire Gauge Tables

I have 4 gauge running to my AP 15001D at 2 ohms, so 950 watts. The biggest that amp takes is 4 gauge even at the full power at 1 ohm. According to that chart a 10 ft run at 100 amps (that's the fusing) could be done by 10 gauge. I wouldn't go that low, but 4 is overkill I'm sure.

I'm in the same boat as OP, and want to add 400 watts, and am considering distributing off the 4 gauge I've got with short 8 gauge runs to the amps.

Also, I recall back in the 90's when running amps, you really never needed 0 gauge, and that was with huge innefficient AB amps.

Hmmmm...

Better be safe and just make it 2 0awg runs directly to the amps //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I agree. He would probably be fine running 4->(2) 8. Overkill just seems to be the norm anymore. It eliminates potential weak spots, so I guess that's good.

 
so i guess 0/1 gauge it is.

I ask this question also because im not going for the competition system. just a regular sounding system. I am not even going to do this BIG 3.

Yep, overkill never hurts, but it doesn't mean you have to like some make it seem. Next we'll see guys mounting a 1000w amp on the battery w/ gold bus bars in place of wire.

In my case it looks like it's just as cheap to get a knu 8 ga kit to add as it would be to do a distribution block.

 
im running 2 amps off an 4 gauge, split into (two) 8's at a distr. block....

I have some extra 4 gauge laying around, do you think it would help to run 4 gauge to the distr. and then (two) 4 gauges to the amps?

Or is that stupid?

I was actually wondering the same thing as i have a 1200 watt amp and a 200. I know the 1200 would be better with 4awg, so can i run it all the way back to a distro and then split it into two 4gauge wires to the amps?
