I have recently installed in a Mazda RX-7:
Alpine 7969 HU - 24db internal digital crossover. 80hz/80hz
Phoenix Gold ZX- 600Ti bypassed x-over running MM465 in front
(150RMS X 2 14.4v @4 ohm)
Phoenix Gold ZX- 475Ti bypassed x-over with 2) MM100's in rear
( 250RMS X 2 14.4V @4ohm)
The question I have is: When is it necessary to reverse the polarity given the 24db per octave slope? How do I determine this? Please explain.
This setup is very loud, tight, clear and highly impressive , but want to make sure all the final tweaks are done.
