okay, i have an idmax 12, d2 sub, and right now, i have the voice coils wired in parallel(1 ohm) (for my audiobahn amp that i hate) anyway, im thinking about buying a 1000/1, and i was noticing the 1000 watts into 1.5-4 ohms, so... if i buy this amp, should i rewire the voice coils in series? (4 ohms)
