ok here's the question: if you have one(1) dual two(2)ohm sub and you run it bridged into a two channel amp, what load would the amp see? 1ohm or .5ohm?

this has started a huge debate at work and would like to know if anybody has some hard evidence?

If you wired the sub in parallel that would give you a 1 ohm load and if you bridged it you would have a .5 ohm load on the amp.

i skimmed over that link and it didn't mention any thing about the impedence reduced by half? just the power doubled!
