I'm competing in MECA Street SQ class this year. If I am reading the 2019 rules correctly, processors are allowed in all SQ classes. Not Sure, guess it's because of factory integration. To answer your question, No, I'm not upgrading to a processor. I'm just adding a pair of old school crossovers to allow me 4 channels on my 2 way setup. Basically bumping up from 150w per channel on 2 channels passive to 150w on 4 channels active.
What should have taken me a few hours took me all weekend to wire all of this up. Everything works according to plan, but my doors being stock is not working. At all. They need to be treated ASAP !!! Only down fall to this for me is I will have no sub bass until my amplifier gets here. Is what it is I guess.
