Not that this answers your question,
but I'm from Minneapolis :-) I don't live there because my dad was military but all my family lives there and I visit all the time.

 

I said 3 inches... look at the tire on teh convertable type thing, goes up a little past the bottem of the rim on what looks like stock wheels/tires. Id say thats about 3-4 inches.

On the other hand... Im from blomington and going to be experiencing the same winter as you are, though L7 is right behind my seat so no worrys .

 

Alright, well they're 12in type e's so idk, i didnt know all the facts so i took them out anyways.. This might sound retarded.. but what if i wrapped my subs in like a blanket.. not too tight, but just to keep all the frost off it.. it was 10 degrees last night, i went to run a mile and i froze my ****ing ***** off.. is it safe though for my subs?
