Wire Overkill

pretty much if you can afford it, go for it, better to be overdone than not enough

I think I will just get 2/0 and do 1 run of power and 1 run of ground.

Heck, I only had 2 runs of + and 2 runs of ground for all my stuff I had. I was too broke to afford more wire. And the wire I had was Soundquest. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

its cheap as hell and with it being so cheap you can afford more runs

2 runs of 1/0 will flow more curent then 1 run f 2/0

I know but 2/0 will be fine and a whole lot cheaper. Im on a budget. Gotta get ready for next summer. Other things to do to my car besides the audio. Not going to be upgrading anymore anyway. Why does this chart say that 2/0 gauge can only carry 283amps? I thought most good 1/0 gauge wire was good for 300amps at 20ft. The chart on the welding supply website says its 2/0 gauge wire is good for 400/450amps at up to 50ft and its 1/0 gauge wire is good for 350amps at up to 50ft. Why the big discrepancy?

Dunno, this guy ran this in his SPL setup and I think its overkill

Can someone answer the question in post #20?

That chart is for household wire.

Wayyyy different.

Ok thanks. I was worried. 2/0 should be fine right?

 

[WOT]

I did a 2/0 welding cable run (positive only) to my back rear batts, and a ground to the floor of the trunk. On 4000+ rms and a 110amp alt.... youll be fine

I have 2 power and 2 ground knu klmx to my 3 C&D 135AH batts in the back to run my D9hopefully tommorow it will all be done so if i am doing that on 2 runs of each you should be good.

Also if needed gonna add 2 more grounds to the frame in the back.

Nah

mechman rhino 220amp $289

DC power 240amp $389

Stock rewound 200amp $200 (im cheap so guess which one I have) //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Alt is doing fine though suprisingly, might get that mechman later though.
