I am thinking about getting 2 12" FI Q subs 1000w rms each but dont know which to get dual 2ohm, or dual 1ohm. I want to use the memphis mcd2500 amp 2500w x 1ohm and dont know how to wire the subs at 1ohm impendance. Also do I need a 2000w amp to push 2 1000w subs or would a 1000w amp work? Thank in advance for any advice.
