i've been bumpin around with 2 kick comp vr's and it def isnt enough for me. i'm plannin on goin to europe in the spring so the budget is tight right now. after i go im lookin to get a pair of 9512's. but for right now i can get a pair of 12" type r's for $200 total. would i be able to get a custom box made for both of these or are they too different to be able to be swapped out and should i wait to get a custom for the 9512's. and would the 9512's be any better then the type r's to begin with. they would be ported, r's runnin off 900w each and the 9512's i would have to buy another amp to supply them correctly.
