I guess I should clarify... There's no such thing as a relay rated at 80+ amps that suits my project in any sense of cost effectivness... In order to swich an amplified signal of 1750W x 2 I would need at the very least a 3PST-NO Relay with a contact rating of 80A+ for a true bypass are...

that's what I got... and that would be peak so it woudn't be that all the time... There's no such thing as a relay thats rated at 83.7 amps... but that stands to reason that since I'm only running at 20.9 volts that I could over rate the relay's amperage rating since I'm running it under on...

Great! That answers half the question... If the highest I run is 1750W at AC current 1750W = V x A I can't do the math without knowing V or A my guess is it's variable on both sides right? Would I be save to just use a relay that's rated for 125VAC at 15A? (Which would give me 1875 max...

Or is it not that easy of a question? This isn't a car audio application but this is the only forum that would deal with the type of wattage I'm working with. This will be for professional PA equipment. I'm building a speaker selection system (much like you would find in a car audio shop) to...
