I get DIESEL POWER there is always an add in it for high output alternators. can I ask why you think you need 2 alt. anyway the web site is PAperformance.com one of the guys at work has a good size cb radio 750watt kicker and it powers it with power to spare. The one for the dodge puts out 130 to 200 amps you can arc weld with that I think. Hope that helps you out
