All you need over a car marketed passive set is an electronic crossover, well and two more amplifier channels. Eq and DSP are not limited to just raw drivers only, and they're not required for either raw or drivers or passive systems.
I used a Pioneer Premier DEH-880PRS deck that had a built in 3 way crossover, eq and time alignment. It only cost about $300. Plus I saved money buy not buying an a passive set, so I could use any mid or tweeter I wanted.
We really could argue this all day. This is one of those "grab a beer" arguements.
