I'm planning on get two Fi SP4 15's dual 2 ohm 3, 000 rms each. I want to go with Crescendo Audio amp(s) didn't know if I should get two BC3500D's or one BC5500D. Also if the rms is 3, 000 watts per sub do you have to have 3, 000 watts rms of amp power? Also this is going in a GMC ext cab pick-up I will be taking out the backseats.
Thanks for the help.
