I read a couple posts on this forum where people were saying to just eliminate the rear sound stage and just go with the front. I was kinda skeptical at first but recently I decided to bridge my 4 channel and send all 120w rms to each front speaker (Polk MOMO 6.5 components). The sound difference was AMAZING. Now my only problem is the difference between my ipod and just a plain old CD. I can play the same song each way and the distortion is much more prominent. My deck has direct ipod control, so it's not just an auxiliary input or anything. I was just wondering if anybody else has noticed this discrepancy.

strong front stage and no rear-fill ftw.

i also have no rear stage, don't need it

i pod quality isnt as good as a cd. one of the reasons why i dont own an ipod.

WRONG!!!!!!

I agree on big front stage,But a properly designed system will have some rear fill...The rear fill should only be noticed by the ear when you turn your head and lean a bit to the back seat,When seated normaly you should not really pick up the rears,What this will do is raise the sound stage up and get rid of the missing void,In my own car I am running 150 watts to each door and then just 50 watts to each rear 6x9,The front stage in my car is dead center and if you are sitting in the car it is right about eye hight..And yes Ipods and any compressed CD will sound like crap..Use the origanal CD or burn a copy with just the one disc on it.

I bet that sounds like garbage, Quality > Quantity

Right. Because you have heard it, and because it sounds like you have also never been in a cavalier with a good rear sound stage! I have taken many many days tearing apart my sound deadening the entire car except floor. from the pictures you cant tell the i made that rear deck, its not the @!#$ty carboard/pressboard from the factory. i made it out of MDF, and the 4 6.5" are also near sealed of from the trunk, so the air pressure doesn't over excurt the speakers or distort the sound they produce. Now through in the amp i have on them and there you go. No its doesnt sound like sound like @!#$, maybe you should consider that maybe a good rear stage just requires work and it can be done and done well.

we obviously have different opnions of what sounds sounds good, i guess you like so stick as many speakers wherever you can fit it them.

wtf does that mean? because it sounds and looks good you have to rag on it?

speakers on the rear deck look ok but scream steal me, the ones in the side look out of place, i dont see how speakers aimed all over the place and at each other could sound good.

I had fit two 6x9's into a fiberglass rear deck, gave them tilt to point forward instead of right at the rear window. When I gave the front more power, and faded upfront with my deck's "digital sound orientation" it sounded great! I had pos xplods though, so it wasn't great sound. you could tell they were there, but the vocals were all upfront, and they picked up some of the lower mids that 6 1/2's in my doors just couldn't hit. With my eD 13Ov2, it sounded great with 10x the staging quality I had before it. Then I blew an amp and only kept the front stage. I did try it with some kenwood 6x9's i had, but they were beasts and didn't fit the deck I made.

REALLY. because i have had many people ask if I did those or did they come there from the factory. I say i did it, and they say it looks nice. just because you dont like something doesnt mean you have to bash it. oh and by the way i take it you think you know eveything about car audio because you have subs firing up and just a front stage.

As far as mark says, my rear deck has a slight raise to it and it sounds alot better then flat. The bigger the angle you put them on the better sound you will get from them. I had a bigger angle, but I just couldn't get it to look good so i dropped it back down.

I'm gonna agree with Stephen. You have alot of "decent" speakers. RF is a good brand but as many speakers as you have you would have to have one hell of an amp to supply the needed power to sound "decent" Plus the placement would probably just end up hurting the passengers ears. There's a reason why manufacturers don't put speakers in the back interior quarter panel. Yot of u probably just spent alot of money and alot of time ending up with the same sound as any "decent" system. I don't claim to have anything better than a "decent" system...but I have spent alot less time and money.

So do you have an 8 channel time-alignment circuit?

nope head unit that i can set a parameters with and mono for subs and a 2 channel for the rear, until i get a four channel.

Head unit: KDC-x889

more sources = more chances for distortion.

the reason eliminating the rear fill improves sound quality is that having rear fill can cause frequencies to cancel each other out. its simple physics really.

by eliminating the rear stage and only keeping the front stage, you have a more solid foundation to tune on. you dont have to worry about time delay and rear speaker positioning and all that crap. wire the front, check the phasing, tune, enjoy.

i will how ever agree with you in saying that sometimes a rear stage can help. for db drag for example, where al your measuring is a db level, then a rear stage can help since all your measuring is noise.... really thats all db is, a measurement of noise.

but if you dont believe me or any of the other guys on here, then keep doing what your doing. go in a couple SQ comps and see how well you do against a properly tuned and built system.

Cavaliers are not sounds quality cars. i know this. The structure, layout, and total makeup of the cars arent great for a sound quality. I was after a presentation factor and good sound not great. Had i have wanted great sound i would have went all components not coaxial and not have went after SPL as much. I do know the rear deck and stock speaker placement is alot further from your ears then yours door or front stage, thus making a time lapse and kind of a mushy sound, but all i am saying if time is taken to setup it up and dial everything in it can sound good.

And more sources does not mean more chances for distortion if wired and designed correctly. go look at some of the best SQ cars, they have many speakers not just a front and rear set. Power and frequencies distorts a speaker by either over powering or playing to low of a HZ. If the power is clean and within the parameters of the speaker you shouldnt have any problems with distortion.

the thread was mostly geared towards sound quality, not SPL, hence why everyone is saying that getting rid of the rear stage is a good idea.

if your shooting for appearance of course what you did can look pretty good. showing off what you have (some one else mentioned it as that "steal me" factor) can make everything looks nice and can make for a nice show piece.

for SQ though, generally less is more. yes, you can have 20 speakers sound great, but the price tag gets bigger too. on a little bit more of a budget, only running a front stage will generally sound better.

it is litterally a simple physics principle. when you have more sources attempting to play the same frequency, there is a higher chance for distortion and frequency cancellation.

agreed. just how bass drowns out your highs.

^^^^Thats one of the main reasons I bought Components for the front doors^^^

Chad STFU.

If you seriously think putting a @!#$ ton of speakers in your rear deck has good sound quality, you need to stop talking. AND stop getting so ass hurt when people say it won't sound as good as if someone who really knew what they were doing got ahold of your car with the amount of money you spent on all those damn coaxials....

I think it's hilarious that you say "Cavalier's are not sound quality cars". In the hands of someone with intentions of building a good sounding sound stage, a Cavalier will sound just fine. They might not be the car's that all the professional competitors chose, but that doesn't mean you can't get good sound quality in one.

I want to say more, but I don't feel like typing anymore. Simply put, stop being a @!#$ cry baby when people call you out, and stfu.

first your last statement mad no sense....... When are you mids and highs ever going to play sub frequency's?

you must have never heard a well designed system. I have a single 6.5 component (amped at 225 w per side) and it can keep up with my subs all day long and sound good doing it.

low frequencies travel further and are more noticeable to ur ear, therefore with heavy amounts of bass, SPL or DB cars have problems with the lows covering up or drowning out the highs since the are a weaker frequency. Makes sense if you have taken any sound class or studied sound.
