go with 1 8" jl audio w7, VERY clean bass, and it can hit SO hard when you want it, sounds good for all types of music.... not made for rap, but CAN be used for it, primarily a rock sub, and it is SO clean sounding... i give it a 15 on a scale of 1-10! i am SO happy i got this sub.... and get jl 250/1 amp to power it
