I remember someone telling me about cookies and making their van colder for spl. For some reason I thought you put frozen cookie dough in there to make it cold haha. Funny how my mind obscures things.we did that one time.
found a huge steal pan that looked like a cookie sheet. it was like 10ft x 8ft for the comp van we had out in ohio, we put dry ice on it and let it sit in the bab of the van till the next day, only made like a .5 db diffrence.
