I think it may depend on your budget. From what I hear going active can get very expensive when you consider you will need an amplified channel for each speaker in your setup. I have a three way setup up front and a two way in the back with 1 10in sub. That would mean I would need 11 channels of amplification and a complex active xover system for the midbass/midrange. Right now I am sitting on one 4 channel amp and a mono block. I thought about bi amping the fronts and running the rears off the head unit but most people have recommended against it.
But I am kind of a noob, hopefully the experts will chime in. I would like to know more as well.
