i perfer more sound up front as well so i set the fade around 75% to the front...it sounds terrible with way to much sound coming from the back (except the subs of course) it sounds like standing backwards at a concert..

Putting speakers in the rear of a car dosen't mean your sound stage will automatically be moved behind you. If you know how to set up your rears properly you can actully move your stage further in front of you (gain better depth). Many cars out there use reflections in a similar way, with outusing speakers in the rear. But not everyone is willing to modify there cars go gain SQ.

I'm trying the second method in my car. If I can't get it to work they way I want it to I will be using rears as a way to make my front stage sound better.

I have. I know the theory and it has a lot of problems - especially in a car environment. I just wanted to know what corner of cyberspace you plucked it from.

I often hear the words "rear fill" in car audio, what the heck is that? It is a term unused in home audio, home theater, live music or anywhere else I am aware of. ‘Rear fill’ is often considered a good thing, since I can honestly say I do not definitively know what it is (though I have used the term too) I will never use it again since it is a car audio construct.

Music, in real life, comes from a finite source either a point source (trumpet, triangle, single drum, etc.) or a plane (entire symphony). The sound will project from the front of you, reflect on the side walls, ceiling and floor, and even off the wall behind you (if there are no walls (i.e. outdoors) then the event will sound quite a bit different and not as loud). A lot of the sound hitting your ears at a symphony is reflected so it is a complex acoustic experience, recorded music of that same event provides much of this information but it can not record all of the nuances. A lot of times they do little recording tricks to recreate the live experience, usually with mixed results.

Can a two channel system recreate the magic of the recording ? Yes
A Dolby 5.1 or THX system should do much better than a two channel if recorded properly.

Can the use of rear speakers accurately reproduce the live event? With 2 channel recordings the answer is ‘not accurately’, but it can sound ‘good’ and it can also do a good bit to artificially ‘recreate the moment’.
Now in a 5.1 system the use of rear channels is required and should be able to get you much closer to the recorded event.

^ very true,

my very first setup (1992) in the SC had USD waveguides running from 500hz and up in front. 500hz and down to 80hz in rear. (USD audio 10" midbass) 80hz down to dual 15" subs in an APbox.

This system when it was dialed in.... it has amazing depth and height. and instrument are very transparent with impressive dynamic impacts.

there were a lucky few that had a chance to hear it back then when it was dialed in.. and they still rave about it today.

But, it was unstable at times with certain types of recordings. because of the precise requirement of the speaker system alignment and the temperature effects on the plastic/leather components of the interior, amp etc.... it must be exactly the way it was when it was during the tuning process.

I think with the digital eq, crossover and delays prosessors available today. i could store different tuning parameters under a certain condition vs just one with analog processors would definately help.
