hey guys! i would appreciate some imput from everyone here k so, right now i got 2 12" MTX Jackhammers with a sony xplod amp.. It pounds pretty hard but i've been doing some research, and im set on getting a FI 15" sub and a Hifonics amp.. But I've got a few questions - Is that $90 difference that i would be spending for the BL be worth it over the 15" SSD? (BL with Hyper Pole and Flatwind) (SSD with copper coil and BP Power) - Im looking at just a one sub setup, so do i order Dual 1 or Dual 2 ? the amp at 1 Ohm puts out 1200RMS and 2 Ohms is 900RMS would i hear a big difference in the BL over the SSD. Thnx guys!! Appreciate it
