Oh no I have the best buy password for that I thought you meant like an instore sale, even so I really don't like infinity products, jbl gti stuff (along with others) is more my style. Yes I work for best buy at location 1426 in edwardsville, Illinois and I am the car audio senior. It is nice because my department finished number 1 in the district, 2 in the territory and number 23 in the whole company for the fiscal year of 2007.
If the box was built for a type-r, I don't think it is going to work for that sub well at all, I say that because infinity always reccomends and claims they work well in small-medium sealed boxes and medium sized ported boxes tuned to around 32 hz. Also make sure you put the correct pole piece in the sub, so It wont sound like crap.
