No longer stereo? That's incorrect... it is still a two-channel source. Adding more speakers doesn't make it "surround sound" :rofl2:

I haven't tested this, but my point was that you might have better left/right staging with rear speakers.

Besides, by your logic it isn't "stereo" now because of the tweeters in the dash.

The only way staging wouldn't matter in rear speakers is if you had a sub and bridged left/right channels (since bass is theoretically non-directional).

Just and idea OldGuy, but maybe take a favorite CD to the dealership and try it out in a touring trim 370 just to see if there's any appreciable difference?

With rear speakers you are having sound waves cancel out from your rear speakers coming in contact with your fronts. Also your stage gets shifted from being forward to being well somewhere where it shouldn't. Subs are not effected by left and right and in a lot of cases they are directional. Bass changes in many ways depending on where the sub is aimed.

The other obvious reason that you missed is weight savings. Although I can't imagine why if you want the rear speakers that you don't put them in. The sound would be better than just front speaks. Agree that the fronts should be upgraded as well and to go with a decent amp.

Roger that :icon18:

I don't think placement of speakers front or rear would inherently screw up a sound system. Wouldn't direction of sound and distance sound travels be stronger factors? And since these are configurable and can be tailored to a specific vehicle and audio configuration, you should be able to adjust power and direction to attenuate sound appropriately. So I could see where an oversized speaker setup like multiple big subs could just plain overpower the ability to fine tune, but some well configured 3.5"s should add value to the listening experience in a balanced system.

Not when they are the only rear speakers and when they are directly at the ears of the listeners.

As what was said earlier, it is what is preferred by the listener. I like to get as realistic to the real thing as possible and that means no rears. Also in a car the size of the Z no rears are needed as stated earlier.

I had rear speakers in my other coupe that is the same size as the Z and it sounded good, Im actually used to hearing music from the back, so right now even with the Touring model Im kinda having to get used to not hearing from the rear.

That is what I am saying it is preference if you are use to them than you will want them. As I stated I try not to use rears.

True, the quality of the bass sound is changed a lot by direction/position (i.e. facing the speaker backwards in a hatch often sounds louder/better). This is really because bass waves are "longer" and if they are too close to your ears they can't complete a full cycle (that's why bass sounds louder 10 feet away than it does right next to the source). By 'directional' I meant more left/right subs not really being necessary (since most music is mixed with the bass and kickdrum panned evenly between both channels anyways) but again it is a matter of personal preference and the audio recording.

Not sure what you mean by waves cancelling out from rears coming in contact with fronts. I think we're confusing "staging" and "sound position" (staging is left/right). Not trying to argue though and I agree with your bottom line: it is what your ear prefers. There's ground rules to reproducing good audio of course, but really no right or wrong way to do audio if it sounds right to the listener.

Getting back on topic, _personally_ I don't think rear speakers have too much to offer in a 2-seater.

Exactly. Balancing is the hardest part (I think this is what bigaudiofan meant about waves cancelling each other out).

The easiest way to balance is to have different speakers produce different (but slightly overlapping) frequency ranges, using speaker type and/or caps. Then you can easily tune front/back balance to taste. There are advantages to having some midrange behind you (maybe less so in the Z), but if it's aftermarket it might be harder to blend them in with the stock system seamlessly and still gain anything.

Given the same wattage, it'd be louder, easier and probably better quality to push fewer, well tuned speakers.

sorry for ranting but audio threads are just asking for it :tup:

370z Needs Rear Speakers
 

Has anyone put speakers in the rear of their 370z and if so what do you recommend for a 3.5 inch speaker anyway?

My doors & dash are Focal's and I'd like to place the 4 inch Focal's in the rear because the door and dash simply don't fill the cabin adequately with sound. Has anyone placed 4 inch speakers in the rear, and if so do you have any pictures of the final results you'd be willing to share?

I know WickedCAS had a 3-1/2" Hertz mid that supposedly would fit back there.

With regards to the entire four speaker debate, I believe hoodust nailed it in the head. Rear speakers will affect positioning (BTW, the lower the frequency, the more unidirectional the sound becomes), not necessarily cancel the fronts out. Given the same signal and no phase shift, there won't be cancellation. Wire the rears 180 out of phase with the fronts - now you're talking some cancellation.

I've heard some very good surround effects in sedans in the past, when done properly. The Levinson systems in Lexus cars use some proprietary surround processing and sound amazing.

So rears won't kill a system if competently installed. But unless there's some added effect which adds to the sound, I prefer just two fronts in the car.

Its awesome to know that so many ppl have installed rear speakers...

Has anyone taking pic's during the wiring etc?

Thanks,

in the case of a 370Z where the speaker size is 3.5" and there realy isn't that many hi-end clean sounding 3." or 3.5" speakers out there unless you spend close to $200-400 (Voce or Hertz) I would suggest putting the money in the front speakers and maximize your listening pleasure. If you must do rears because you are so used to haveing rear speakers since you were 16 years old and that is all you ever had... Then do the rears... You will find yourself having the fader on the radio positioned more towards the front since the better sound will be in the front. If you do 3.5" speakers make sure you have some kind of a bass blocker in line... they will not keep up with low frequencies for long period of time.
