ok at the moment i have 2 15" pheonix gold Ti's that are in a sealed enclosure ( decided i didnt really want to port them due to space in trunk) there gettin 900 rms right now but my question is would one 15" Re SX in a ported box recieving 900rms be louder then my current set up? and also does the SX need a big ported box? thanks ini advance
