Default Can a 4 channel amp bridge in stereo??? Have info need options

I have 3 amps. I have a Fosgate P500-2 running bridgeable into one 10 inch sub. It sounds great.
Then I have a Fosgate 400-2 pushing a pair of infinity 6 1/2" door speakers. Again, they sound great.
I have a Kenwood PS200T amp powering the 5 1/4" Infinity speakers in the rear but I have just received a Fosgate P400-4 and wanted to know how I should hook this up since I only have the 5 1/4" speakers in the rear.
Can they be hooked up in stereo bridged for more power to the speakers or can I add another pair of rear speakers to go along with the 5 1/4" or do I waste a 2 channels of this amp.

The 500-2 specs for the sub
125 Watt - 4 Ohm - 2 channel(s),
250 Watt - 2 Ohm - 2 channel(s),
500 Watt - 4 Ohm - 1 channel(s)

The 400-2 specs for the front speakers

RMS Power @ 4 ohms
100 watts x 2 channels
RMS Power @ 2 ohms
200 watts x 2 channels
Bridged RMS Power
400 watts x 1 channels

Kenwood PS200t
RMS Power @ 4 ohms
50 x 2 channels
RMS Power @ 2 Ohms
75 x 2 channels
RMS Power @ 4 Ohms Bridged
100 x 1

I want to replace the back speakers with the P4004 (I have one that's just sitting around)
and possibly bridge the amp to stereo (if possible) for much more power.
The specs on the
Fosgate P400-4 are:

RMS Power @ 4 ohms
50 watts x 4 channels
RMS Power @ 2 ohms
100 watts x 4 channels
Bridged RMS Power
200 watts x 2 channels

Could I actually add a second set of rear speakers???
I didn't think that this option would be possible.
I have a C5 vette and the 5 1/4" in the rear are the largest that the converible will hold without modification.
I don't know if I could add any more speakers conspicuously.

Just looking for ALL options
Thank you

You can run 1-4 channels from virtually any 4 channel amp.

It's unlikely that the rear speakers can handle or need more than the power that you're getting from the Kenwood.
