noActive is when you split your hpf BEFORE amplification. Passive is when you split it AFTER amplification.
Edit: My 6x9s are also ran active =)

Clearly you must not understand/comprehend the concepts at hand.active to me is just a bunch of hype
I ran some CDT HD active. Ran em with a Pioneer 960mp
Alpine amps all around.
Spent hours tunning.
Next car, I bought some CDT ES, ran em passive and gave em 200rms and they sound MUCH better
