Bridging mono amps

So, here is a strange question: How can I bridge 2 mono amps?

I am trying to optimise the sound from all the equipment I have. I am currently running 2 systems with identical amplification - each has a Musical Fidelity MVT preamp and 4 MA-50 monoblock Class A 50w poweramps, vertically bi-amped. The bedroom system is using Acoustic Energy AE-1s, while the listening room is using Proac Response 3.5.

So, since I have 8 identical MA-50 mono amps, I am wondering if I can bridge pairs of them to increase power to the Proacs.

BTW, does anyone have an MVX or MX preamp stashed away that they'd sell?

Thanks, Samir.

Thanks again for the responses. I'll probably try this over the holidays - have all the equipment, so not much to loose, except my wife yelling at me for the mess it'll create.

The history: system generated great sound incl bass w/ my Rogers Studio 1As. With the move to the new house, the bass got sucked out in my new listening room. (I need to do some room treatment too). To compensate, I've moved to larger and larger speakers, currently Proac Response 3.5, which are not as efficient as the Rogers. I'm told that more power might improve the bass..thus this current thread.

Thanks very much. . Driving the amps w/ an inverted signal is easy..the preamp has 2 pairs of outputs, 1 pair is inverted.

How do I figure out the polarity of the speaker wires? Does the red go to the amp thats getting the regular non-inverted preamp out?

Any thoughts on the advisability of doing this? What sonic benefits and tradeoffs should i except?
