I have tossed the idea around for awhile, and came up with this set up, it puts out 50 degree air, 2 small 12 volt fans so not allot of volume but you can definately tell the difference, its designed to stand up behind the seats, i need to put the base on so it can stand up, it has 5 3"x7"x1.5" blue ice packs inside, the air goes thru the box like a maze blowing up down and across each pack then exits the 2 flew hoses which come out at shoulder level to each seat
