It's Ahmed,Ws
I'd prefer a head unit with active processing and auto eq to get me in the ball park since i don't wanna sit in the car for a couple of hours every day.IMHO manual tuning a full active system can be a PITA.The biggest question is whether you intend to go three way or two way.A good tuned two way can beat a three way that isn't properly tuned.
It's a great amplifier, the thing is the more complex you want things to get the more channels you're gonna need.Another alternative is running quasi active.
If you can share what you intend to achieve plus how much time and money you're willing to spend only then I could suggest some likely candidates.
Cheers
