the ohm dilemma!

the ohm dilemma!
Okay so I am trying to figure out a method for solving my current problem. I am running a fosgate punch 400 2 channel amp and i've got it bridged down to mono for maximum RMS, but the bridge puts it up to 4 ohms. The seconds part of the equation, would be my two kicker 10" subs, each is running at 4-ohms, but i have them paralleled in wiring within my ported box, which puts them down to an impedance of 2 ohms. So what I am trying to do is keep my amp at maximum power running at 4 ohms and get my paralleled subs running properly with my amp.
The reason I ask is because my amp is running incredibly hot right now... like scolding hot! After much research and questions on other car audio forums, I have determined the amp is overheating due to the mismatch in ohms between the amp and the subs.
Would it be possible to wire up the subs within the box, so that i have a wire connection from the + of one sub to the - of the other, in turn putting the subs up to a proper 4 ohms for the amp?
Blah! I am novice when it comes to this stuff, so any help would be greatly appreciated. Thanks in advanced guys.

IN this situation, just buy an amp that makes max power into a 2ohm mono load....
Also to make a good clarification for you. Amps don't have "ohms" the ohm rating of an amplfier is based on the load it sees (speakers, subwoofers). Bridged, your amplifier can safely handle a 4ohm load(it doesn't put out 4 ohms, the amplfier itself has NO effect on the "ohm's" only the speakers do.
If you get an amp that makes full power at 2ohms. and your subwoofers are wired to a 2ohm load then your amplfier will be working in it's optimum power range.
How you have it now, you are trying to force your amp to make twice the power that it's rated for and it just cannot handle that so it's getting really hot and might not last too long doing it.
