If my amp is
1200 watt peak power
230 watt rms x 2 channel @ 4 ohms
what would it be at
???? watt rms x 2 channel @ 2 ohm
and
???? watt rms x 1 channel @ 4 ohm Bridged
My amp is 2 channel and not 1 ohm stable and is 2 ohm stable but not when its bridged. Bridged is only 4 ohm stable. Thanks.

In general you could expect the camp to have an RMS output value around twice the 4 ohm value giving 460 watts as 2 ohm is half the DC resistance value from 4 ohm (this means twice the power transfer). Bridging will usually have a similar effect, but now you will only have a single channel going to a 4 ohm load.

So bridging at 4 ohms would be the same power out put as using 2 channels @ 2 ohms essentially?

Exactly. But will all of this you need to keep something in perspective. Doubling your power only increases your output volume by 3dB (3dB is literally defined as a doubling). 3dB is generally considered about the smallest noticeable amount of volume difference. So when you talk about doubling your power, it is a barely noticeable gain in overall volume.
