DedicatedEnthusiast Posted January 13, 2014 Report Share Posted January 13, 2014 Welding supply and coppercableman on ebay seem to be quite popular but what about wireandsupply.com or electronbeam.com (EB-flex ) wire? Also I see that 1/0 welding wire is rated for 350 amps at 50 feet while 2/0 is rated for 400 amps at the same length. I don't expect using more than a 20 foot run at most so what size cable would you guys recommend using for a Crescendo BC3500D at one ohm which calls for a 300 amp external fuse? Lastly I noticed there is an ultraflex cable available from welding supply (as well as from directwireusa.com) that claims to contain 4x the strand count of the standard wire yet the amperage ratings are the same?

Wicks Posted January 13, 2014 Report Share Posted January 13, 2014 I use "RadaFlex" and love it. http://www.cableyard.com/RADAFLEX-10-AWG-Black-Welding-Cable_p_12.html Super flexible, reasonably priced and great customer service. For your application 1/0 is fine but if you upgrade to 2/0, you'll be even better off. Just depends on the tradeoff of cost and room for the bigger cable.

SnowDrifter Posted January 13, 2014 Report Share Posted January 13, 2014 Welding wire isn't like car audio wire. If you buy 1/0 OFC, that's exactly what you will get. Nothing oversized, nothing undersides, no CCA or plated anything. Just plain old vanilla copper wire. That being said, there is a variance of strand count. And more/thinner strands is more flexible then fewer/thicker strands. Depending on how much space you have and how you will be routing the cable, that may be a factor you need to consider. Also of note: You'll want 2/0 welding cable to stack up against most oversized car audio 1/0. ~~~~~~~~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...
