KNU KCA 4 Gauge wrei?

[bgowdy 5,000+ posts]

Please dont nut-hug KNU. Im just curious about it.

Ok so i have been looking at this KNU KCA 4 gauge wire.... and it doesnt look like 4gauge to me... It looks quite a bit bigger compared to other companys that offer 4 gauge, hell i looks to be about the same size as the "Bullz Audio 1/0" wire.

Has anyone actually measured or compared to see what the actual size/gauge it is? I know that standard 4awg gaauge is not this big, and KNU wire is always bigger then what is "rated" to be?

I have some KNU 4 gauge,8 gauge, and 1/0 in the garage. If you want a picture of them all.

It probably is the same size as bullz 0 gauge lol. Great wire and fit in my AQ1200 4 gauge terminals just fine. I have no idea what standard 4 gauges exact size is though so I cant really say according to that.

I've got some sitting next to me, so I figured I'd stick a ruler across the end. It's 3/8ths of an inch in diameter.

I don't know what the standard AWG sizes are. I'd imagine it's a bit oversized, as they advertise. I do know it's nice wiring and wonderful to work with.

see i was going to just get a roll of the bullz wire, its really not that bad of wire for the price and run multiple runs of it to make up for what it lacks. Then i seen a pic of the the KCA 4ga and was like d@mn thats the same size really(the actual wire vs wire part not counting the jacket) lol, if thats the case i figure i should be able to run multiple runs of it and have the same outcome in the end. Idk if it would work that way but i figured it would.

If you're running multiple wires you'd need to fuse each one, thus negating any savings you thought you might've made.

i dont run fuse's, i havnt ran them for a few years with out issues(knock on wood). I know its not the best idea and im not going to recommend it but i dont. But if i did i know i have to fuse each

I was planning on multiple runs of KNU for new setup but figured I'd be better off replacing my current run of KNU 1/0 with 2/0 sky high.

i see lol.. i was thinking about just doing 4 runs of the kca 4ga but then i thought about it i would hate to get it then it not be as big as i thought lol

I've got knu 4 gauge now in my car. Really impressive, flexible too. I've got another order of by 4 gauge coming in tomorrow. I'll throw up some pics once I get it.

From the web.



To be fair, they didn't compare to any high quality brands. But as far as bargain brands go it's the best choice.

I run 4 Gauge KCA at the moment. Its too big for my Rockford Prime 1200 4 gauge inputs. Great wire for the price imho.

my only worry is it not being big enough tho. It may be big but its only rated like 100amps by KNU, and i know the bullz will handle what i need it to with multi runs, when its all said and done it need to be able to hold up for atleast 250amps. Well maybe 200amps, the most i really plan to run is 2500watts

would 4 runs(2positive & 2neg) handle 2500watts rms?

I don't see why not. My single positive run handles around 1300W without any issue. I would advise fusing it since it is CCA.

i dont run fuses, and have always ran cca i just pay close attention to voltage for spikes etc. I havnt ran fuses for a couple yrs now with no issues(knock on wood lol). For now it would only be supporting maybe 1500 watts. I know for 1500 you can use 80-100 amps for say. But once i get the other amp i would tune them for 2500 so that would need about 175-200amps maybe 250. but idk

Yeah, should be OK with the two runs of 4 gauge, ofc would be best. And I would fuse it too, since you are going to be running it close to it's limitation.

But from what I read, 2 runs of 4 gauge it's roughly equal to 1 gauge. The general rule of thumb is doubling the wire increases gauge by 3. 4 and 4 makes 1, 8 and 8 makes 5, and so on
