I saw 12V AC compressors for truck cabs on eBay. The problem is that they are only rated for about 6500 BTU maximum. I'm sure that's fine for keeping a truck cab cool overnight, but not nearly enough to cool off a heatsoaked interior on a 100 degree day with the sun shining on the car.
I haven't been able to find an official spec, but I would guess that my stock AC system is somewhere around 18K BTUs while cruising down the highway with the blower on max. Someone quoted a service manual for a 6th gen Civic that said the system is 14K BTU, but the 6th gen has a half size condenser and my 7th gen has a full size condenser so I could see that adding some capacity.
