Fk what you've been told. Do what sounds good to you. You know what the most bland sound in the world is? An RTA tuned system. One done to flat line on an RTA. It's "correct" just like deleting your rear fill is correct as there is only front stage in live music, but RTA flat tune sounds like SH&T. Tuning on the RTA for a perfectly flat response curve is like hitting the DOLBY button on a cassette tape. ........... but it's "correct". *rolleyes*
We all hear things differently, use different products, in different cars, and at different ages we also have changes in our ear canals and ear drums that make sounds disappear completely that you could hear when you were younger.
I personally find rear fill annoying, but that is because I have been running with just front comps since 1993. I currently drive a BMW X5 and it has ten speakers plus sub and I can't hear any of them except the front comps primarily because that's what my ears expect to hear after all these years. I'm sure I'd notice if 8 speakers dropped out though! Am I expected to remove all the rear door and rear sat speakers from my BMW? Hell no......... They sound good, and are all Harmon Kardon. I'll be damned if I'll remove those.......... If you like how your system sounds then just keep adding to it, not taking away.
It took me two decades of car audio to know what I want, and every year something comes out and changes the game. The difference is listening to everything and deciding what you like, not listening to whatever everyone else likes. Tell them if they want it a certain way to pay for it and you'll gladly install it.
For the record though Active sounds excellent. Just do it because you like it, not because you're told. That's being someone else's beyatch.
