    Do you need rear speakers in your car to have a good sound system?

    My opinoin > Anything besides a single cab truck needs rear fill. You dont need highs in the rear but you need a mid range driver. The way i try to set up my system is to have have an ambient audio source. Meaning you cant tell where the sound is coming from. It should just be there.

    Red and all you other sq competitors please give us your opinoin

    I may not be a sq competitor, but they really are not necessary if you ask me. I honestly cannot tell that their are no rear speakers in my brothers car, and I notice no real difference by fadeing my radio all the way to the front channel. Then again, I never sit in the back. On the flip side, if you only have rear speakers, it just sounds bad.

    So in my opinion, no, you do not need rear fill. Adding rear fill could even (while unlikely) cause cancelation and such, so front channel is all that matters to me. Of course, subwoofers are in the back, but they generally fill the car with music anyway, and you cant necessarily tell it is in the back.

    But their is no way to change anyones mind, so keep using rear fill if you like it.

      Basically across this forum there are tons of opinoins on this subject as there is with many others. But this is one that i see causing new audio enthusists a great deal of head ache. My aim is to get many opinoins and proposed setup ideas out there for people to reveiw. Instead of spoon feeding them we can get a good knowledge scource going. Sound staging a vehicle isnt all that easy. Sometimes it gets rather hard. And i think we need some info on this forum to help people with it. And hopefully this will be a start

        i would say it adds a nice punch into it like if u turn ur head u can still hear the sound fill in all over :-D single cabs no need like sansoo24 said other then that id say yes just for personal pleasure

          last time i checked...you only need two speakers for stereo to work. no real need for rear fill...i couldn't care less about anyone that sits in the back seat. however, my next setup will have rear speakers for 4.1 surround.

          when you go to a concert, you're (usually) not IN the band, you're in front of the band, rather, they're in front of you. you can tell where the sound comes from.

            agreed. If you want a _good_ system, You need rear speakers.

            If you've ever been to a movie theatre and have had someone cough, chomp, or yap behind you- you can easily understand the significance of human hearing and its complete range of perception. Your favorite movie could be blasting in a great scene, but if you have some old lady behind you yapping to her friend, you'll definately notice it.

            Maybe I'm biased because I hate when people behind me talk during a movie...

            Maybe humans hear better behind them than in front of them - I dunno.


            Bottom line: Rear fill is necessary for a quality audio experience.

              I think you're mistaken. If you were right, companies wouldn't be spending millions of dollars on developing SPDIF, 5.1, THX, etc.

              If done properly, a car could be a perfect mini-theatre within itself (obviously not while driving). Car's are a very conducive environment for movies and audio when parked.

                actually, it would be more like the old lady sitting behind you...saying and sounding exactly like what they're saying in the movie. the left front is the same as the left rear and the right front is the same as the right rear

                  Question? Car has no subs and only 6.5 components up front. You are proposing that these 2 little speakers can adequately fill the entire vehicle with sound. Regardless of whether you have rear passengers or not, I dont think they can. Maybe if you have custom kick panels or dor pods that focus them the right direction.

                  I guess the biggest deal is with sound staging. I dont agree that you want to setup a car audio system to try and mimic a concert. That just sounds stupid. Your car isnt a stadium so why try and make it sound like one. In my opinoin you should never be able to tell where the sound source is. The sound should just fill the air evenly throught the interior.

                    for SQ there is no need for rear fill...dont think about the damn passengers, from the drivers seat rear fill adds very little. look at any winning SQ setup....chances are that they have 3 or more comp sets up front and maybe one in the back if any!! now, for movies and such rear fill is important but until all our audio CD's are 5.1 im not gonna worry about it. there will come a time when cars are 5.1 ready, as said before a car setting is very conducive to a 5.1 setting....but until then ill let my 6.5 comp set and sub fill my car with sound, even for movies...time for the flaming

                      if you have spent any time in a mixing studio you'd realize that rear fill isn't necessary... unless you have four ears.

                      You think you hear 'better' from behind because she is talking toward you. if she turned around and was in front of you you'd hear her even better.



                      I agree you need rear speakers if you want to listen to 5.1 surround (generally speaking) You can achieve surround sound with only two speakers, but you have to be in the sweet spot which isnt practical in a car.

                      so if you want to hash it out... for music you only need front stage, for movies you need rear speakers.


                      having a sub or not is a mute point, you need one to reproduce the lows regardless of what set up you end up with.

                      now preference is a different story. go with what you like

                        I see your point with the sq setups. I still think a mid ranger driver or 2 in the rear wont hurt. The thing im concerned about is only having a set of components up front. (2 mids 2 tweets). Is this adequate for proper sound quality? 3 sets up front would absolutely work. But im concerned when i see someone ask if they need rear speakers when they arent amping the front ones and only running them off a head unit. Those 2 front speakers are gonna be kinda week then arent they?

                          well thats different. i have no rear stage but i certainly amp my front components. if you're running it off the head unit, having rear fill won't be a bad idea...but it won't sound as good.

                            Common lets be real here, for a car audio system, it has to have rears if you want it to sound any good. Surely i've you've been blasting away for years in the front seat you will think its fine.

                            However step into a car the has been configured properly and you'll notice the difference straight away.

                            I would run 3 way components in the front amped of course, with the tweeter position up high in the cabin. The rears would be 2 way mids, which can be powered from your head deck. Depending on the sound quality of the mids, Iíd probably install a small 8 or 10" sub as well (amped).

                            Once its all installed making sure that all the polarities are correct, and that they are pushing and pulling together and not out of sync.

                            I know this might sound daft buy play some opera or classic music, push the fader right back, close your eyes, sit how you would in the driverís seat and listen. Slowly increase or decrease the fader until you think it sounds just right.

                            Do it a couple of times, and see what kind of number your are getting.

                            Make sense?

                            This is how the professional do it.

                              Its a matter of personal preference, there is no "right way", unless you are going for full surround sound the you do need those rear speakers for the full effect.
                              Stereo is defined as "Two channels of audio information recorded and played back in such a way as to recreate a sound stage giving depth and breadth to audio reproduction."

                              personally I feel that the rear speakers give the audio more depth but again thats just my personal taste.

                              I say do what makes you happy and dont be a sheep
