Why Dont People Use Rear Fill?

[Symon_say 10+ year member]

helotaxi you made a real great statement, that value info, but i change from front speaker only system, to front and rear (i'm working on a carpc son i'll have 4.1 surround), i can say the music sound deeper and i love it, comps only sound really great, but the rear fill, propertly set is really nice, just don get crazy buying high end comps for real fill, get a nice set of coax for that.

why?

1. Because, I don't like how the system sounds with rear fill, though with excessive time alignment it can be made... o kish. Music isn't recorded in 4 channels...usually //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif 5.1 setups with the extremely rare and small selection of re-mastered 5.1 music could be counted as an exception.

2. i'd need another amp, or i'd have to cut down on how much power i'm running on the fronts which would detract from the excellent sound already present that already fills the entire vehicle to the point of pain if you so desire

3. I'd need another set of speakers. That would also detract from funds available for a badass front stage which is all that is necessary..

Usually, people who are running rear fill are doing it for all the wrong reasons that would be easier fixed by simply fixing the problem at the source - for example...running your highs on the rear fill?! WTF. Great, now all the voices come from behind you while the guitarist is wailing away in front of you...with massive time delay between the two sources to boot. How that is going to give you 'clear highs' is beyond me. If the current set of speakers can't produce the midrange and highs clearly, they likely ****. Instead of spending $ on an amp and speakers for the rear, just get a decent set of fronts. Problem solved, and without totally destroying your soundstage and sound fidelity

Because I don't have ears on the back of my head //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

You don't have them on the front either, do you? Not terribly valid logic there.

None of this really answered any of his questions. These are just your opinions as to why not to have rear fill. That's not a bad things, just not the facts.

My answered were aimed more towards "advantages & disadvantages"..

1: you are a dumb ass2: see number 1

Hmm.. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Just trying to be humerous... My ears might be located on the sides of my head, although each pinna is angled forward //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

honestly this is a overtalked about and debate question which only starts crap. Honestly, if you want it do it, just do it right. if you don't want it don't use it and leave it at that. There are technical reasons why its not good but there are also technical ways of getting very good results from it. I was impressed with a Focal canadian demo car using rear fill. So just go ahead and do it if you want.

Some great answers here. I got a lot of different answers when I asked a similar question about rear fill. I have noticed a few things when researching weather to go 2 or 4 ch. amp and rear fill or not:

Most everyone who says no to rear fill is running at least one subwoofer.

So, are you going to add subs? If not you'll probably want rear fill. You will need them to supply enough bass, more than likely. I will be installing my focal comps this week on a 4ch. amp and some infinity ref. 6x9's for rear fill. If I decide I don't like it I'll replace the rears with a sub. I also like the way rears fill the car w/ sound. Of course I can't compare it to having good front's w/ a sub. Yet.

I dont' use rear fill for 2 main reasons:

1. My car's relatively small. Adding rear fill won't do much for me. I continually work on my front stage and just don't have the patience to t/a & eq a set of rear speakers aimed at the back windshield...I don't wanna tackle that reflection issue.

2. I can leave them out of the rear deck and allow some of the pressure in the trunk to escape.

I plan on rear fill off the hu, so it can be turned off it wanted, or if i have passengers, turn it on.

It can also depend on the aplication, My main car which I use rear fill, is a 4 door Hundi Elantra which covers alot of area, My truck project is a Ford Ranger extended cab which I will not be using rear fill. Though I could, overall it will probably be better without it.

That's dumb and quite far from the truth, at least in my case.

I don't use rear fill for one reason, and one reason only.

1. It sounds like shit to me.

Me only having a front and substage certainly has nothing to do with lack of funds. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

IMO size of the cabin doesn't matter at all, I eliminated rear fill in my 93 Caprice sedan, and continue not using rear fill in my 95 Caprice Wagon, as far as a car, the cabin won't really get any larger than that unless you're driving a limo.

Well....

I'm sure it might have been said....

Efficiency and Cost Savings.

Lot of work to get it to work. Worth it? Ehh.... not when the same effect can be achieved utilizing only the front.

You'll save by not having to get the speakers, maybe on fabrication to align them, save on wiring, save on amps and power consumption, so on and forth.
