how do you bridge a power amp

Well, for a start you make sure it's one that's designed to be bridged.

Then it's usually a matter of switching off, flicking a switch to select bridged operation, then reconnecting your speakers to the two positive outputs of the two channels, which are now operating as the push and pull of the mono amp it's just become. Power up and you're away...

Nope. Two bridged stereo power amps = two monobloc power amps = single amping

Four bridged stereo power amps = four monobloc power amps = biamping

Or you could use two stereo amps, each in stereo mode, to biamp

Don't even understand the question now, but i suspect you'd either a) get no sound or b) grenade the amps. Why would you? You either use one input, switch the amp from stereo to bridged mono and do that, or you use the Ys, run them in stereo and biamp. Or am I missing something?

No calm cool and collected, but if he comes back and asks what happens if he uses the Y connector, bridges, connects mains voltage into the other set of speaker outputs and pours a bucket of water in through the ventilation grilles, I'm outta here!

I think at this point I give up...

Oh, I think I can't. No, using the Y cables you can use one amp to drive left HF and LF, and the other to drive right HF and LF, or one to drive left and right HF, and the other to drive right and left LF.

I'd use the latter option, but if the power amps you're using have 'daisy-chain' outputs, you can connect to the HF amp, and then use standard interconnects to feed signal through to the LF amp, with no need for the Y-cables.

Isn't dry ice or liquid nitrogen more common? Would have thought liquid hydrogen was a bit dangerous in a busy kitchen with all those naked flames...
