SnowDrifter Posted March 13, 2013 Report Share Posted March 13, 2013 And while I'm on a roll here: keep in mind that lots of car audio wire is oversized. For example, KnuKonceptz Kolossus Fleks is made up of 5145 strands of 36 gauge. Which gives it a cross sectional area of 65.3sqmm - making it roughly equivalent to 2/0. ah ok sounds good. also as I've been looking I've noticed that the charts that say the amp capacity for a particular wire most of them don't match... and all of them put 1/0 gauge at under 250 and most put it under 150 but I've been told that a single run of 1/0 was fine on up to I think they said 300 something... anyone have a chart that accurately says the amp capacity of different gauges? IMO amp capacity is all based on how long your runs are You can look at this. That's the most amount the wire can carry safely, regardless of length. Look under the "chassis wiring" column http://www.powerstream.com/Wire_Size.htm Here is what I use. Ideally, try and keep your voltage drop below 5. 2-3% being preferable http://www.nooutage.com/vdrop.htm ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

EDIT - and probably smaller than a 320A fuse Thanks I was pretty excited about the alt myself. kind of like a school girl, in a dress, on a swing. lol It's warming up enough that the donut-punching cyclist douchenozzles are getting their two wheeled fagmobiles out.

Carbon Posted March 13, 2013 Report Share Posted March 13, 2013 technically speaking though copper is copper. Except you have different kinds of copper, hard or soft copper as a example.Multiple runs should be easier to do then a huge wire. In reference to current flow. Not copper density.

HunterJohnson Posted March 13, 2013 Report Share Posted March 13, 2013 go to craigslist and get 2/0 wire. I got mine for 2$ a foot, I love it Scion tC SQ BuildiPad mini, lots of fabrication, daily drivenFord Explorer C Pillar Wall Build Just a cheap car to destroy with bass Link to comment Share on other sites More sharing options...
bassfreake Posted March 13, 2013 Author Report Share Posted March 13, 2013 Ok thanks I'll keep that in mind when i do my upgrade Thanks I was pretty excited about the alt myself. kind of like a school girl, in a dress, on a swing. lol It's warming up enough that the donut-punching cyclist douchenozzles are getting their two wheeled fagmobiles out.
