Double bridging an amp?

[Accipiter22]

I have a 2 channel amp, obviously I can bridge it and run one sub....but can I double bridge it (say using the Left + and the Right - , and Left - and Right +).....since when I bridge the amp it puts out more power per channel....at least if it was single bridged....

You won't be bridging it, you'll just be running both channels. And they'll probably be out of phase with each other, and it'll sound like crap.

Nope.

The channels are usually arranged something like this:
Left + = Left signal
Left - = ground
Right + = ground
Right - = Inverted right signal

Connect a speaker between Left+ and Left - you get a normal signal (same with right+ and right -).
Connect a speaker between left+ and right - and you get a double signal (bridging)
Connect a speaker between left - and right + and you get no signal (you've connected both ends of teh speaker to ground).
