Im deciding between these two subs. I'm not looking to spend too much and i have heard that these two subs arent pricy. I already have the Fosgate Power 851s Amp, so i just need the subs. I'm looking for SPL but SQ is also important. I know that the kickers THUMP but arent that good on SQ, I just havent ever heard a V-max so i dont know, ive heard good things about it though.
