I can't decide!
I listen to a lot of rock, metal, electronic (mostly trap and dubstep), and some rap. I'm gonna put either sub in a ported box and run it off my Hifonics BRZ1200.1D that I have from my old build, but I'm not sure whether to get a 10 or 12. Space isn't so much an issue, but I do at least need to be able to fit my toolbox in the trunk with the sub (I drive a Jeep Cherokee XJ).
With that in mind, would a 10 or 12 be better? I've had two Type R 10s ported in a prefab (hated it), and currently have 1 Type R 10 sealed (it's not bad, but quiet). Now that I have Polk MM6501s amped, I need an upgrade for the sub.
