Main question is , i listen to mostly rap and rnb, how much better is the w3 oppose to the w0 . quailty? hard hitting lows? etc. does a W0 still have the Jl quailty? second question is i have bout 4 by 4 foot trunk. Can i build my box to spec for the jl w3 12 , and put my W0 in it in case i dont like the w0 i can upgrade to the w3. by that i mean , i know a to small box for the sub mounted on it is no good, flat ugly beats. can you build a box to big as well and lose potential? or would it sound the same as if i built it to spec for the w0.
