leaving aside questions of whether the amp is rated to run a 4 ohm load bridged, if you bridge it, you can only run one channel (ie one speaker) off it. Onaccounta it's monophonic, not stereo, after you bridge it.
Besides, you don't need more power than you use. THere's this physical law of the universe we occupy (at least our four dimensions) called Ohm's law, and it states that for any voltage swing (ie for any loudness you try to achieve with your speakers) the current (and therefore power)has to be exactly, precisely, unvaryingly the same whether it's a 100 watt amp or a 1000 watt amp. If (and it may be unlikely) a more powerful amp sounds different at the typical one to 10 watts that average listening levels call for, it's not because of the power. Might be because a lower output impedance allows it to drive a difficult load better, but the MMGs present a load much like a resistor - - about as easy as it gets for an amp.
There's lotsa blah blah blah about how the 1.6s (which I used to have) need big power to come alive. Well, number one, if I listen at my normal levels, even the peaks aren't consuming 50 watts regardless of the amp, and a more powerful amp cannot make a difference. I measured the difference between a 50 watt amp and a 250 watt amp in the bass - - there was zero difference despite what people thought they heard. Now, if you listen loudly enough to push the speakers into significant compression, more power will likely mean that the compressed sound doesn't also include amp distortion, and that would be a good thing. But you have, technically, exceeded the speakers' capability already if you are compressing audibly . . . .
