SnowDrifter Posted November 22, 2010 Report Share Posted November 22, 2010 Aluminum vs copper? What makes one vc 2 ohm, and another 4 ohm? ~~~~~~~~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...
Playa Named Joe Posted November 22, 2010 Report Share Posted November 22, 2010 Aluminum dissipates heat faster then copper. To achieve different ohmages of coils, the coils are different in wound length. The ohmage states the amount of resistance in the wire, so a longer wound coil would have a higher ohmage. Correct me if I 'm wrong someone, I'm tired so I'm not sure if that makes scene. 1994 Pontiac Grand Prix build Link to comment Share on other sites More sharing options...

Is there any difference in efficiency between ohm ratings? ~~~~~~~~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...
bassl0va Posted November 22, 2010 Report Share Posted November 22, 2010 Is there any difference in efficiency between ohm ratings? You mean in the spl@1w/1m? Using thicker wire will also make the ohmage lower, and increase power capability.
