two 10x are going to play rock music better than a 12 because they can move quicker and rock music doesn't really hit very low. a 12 would be better to have if you listen to more rap and hip hop

i would get two rockford fosgate stage one 10s and a 325.1 amp, and a sealed box. if you buy this stuff of e-bay it won't come with a warranty, but it will save you about 150-200 bucks. I bought 2 RF stage 1 12s a 325.1, a 2 farad Massive cap, and a sealed box. if you want to know where i bought my stuff from just pm me.
