very informative

 

hmmmmm acording to this I "can't" be in the prostock becouse of the fact that I build a sub floor above the stock floor.
So where do I sit ??? from what i can see I am still in advanced 1.

 

I was just wondering...it says equipment must be purchased through retail stores, and competitors must provide receipts....

I am going to be running a DD 9512, I dont even think that sub is available in any retail store.. and there is no receipt for the sub or amp
