Speaker Size
 

I've seen too many different sizes listed for the front and rear hatch speakers. What are the actual sizes if I want to buy aftermarket speakers? 6 1/2 for the front? 3 1/2 for the rear?

Please help...

6 1/2 front and 4 inch in the rear. I am not officially sure about the rears but someone who has done them should be able to help.

Additional help needed...

i am going to be installing a single 10" and mono amp, if i mod the speakers, is a 4-channel necessary? If so, is a cap necessary at this point? In my old IS250 in which installed 2 12" and modded all 12 speakers, i had 3 amps, 1 cap, and an extra battery.

Need help...

Or simply no.

Also upgrading the speakers a amp is a good idea, but you can run them off the head unit.

Thanks, I saw the cap thread, just needed some reassurance.

Are components necessary for the front or just the speakers? What is your recommendation?

Yes I highly recommend going with components, as they have a tweeter and woofer. This way you can upgrade the factory one in your dash and your door panel woofer. Otherwise you are going too have, strange off axis sound, strange sounding music with the factory tweeter in use "if you decide to use it", It is a lot easier to do everything at once. I would just buy a component set install them and be done. Better to take apart things once instead of 2 times.

If you have a decent Head Unit, you could replace only the woofer in the doors with good two-way speakers and compensate the “strange off axis” (as bigaudiofat stated) with the HU parametric equalizer.

Placing 4 inch speakers in the rear is a waste of time and money.

:iagree:

I had 6.5" Infiniti front speakers installed via Best Buy. They had to use an adapter ($14). The trash man picked up the originals this morning. I should have photographed them--sorry.

3.5" speakers will drop right in. 4's will fit with modification.

Rear speakers are not a waste! They add quite a bit of additional volume in the car plus when you play DVD audio disks you get full surround sound. Very Cool!!

Plus I like rear fill but its not for everybody.

Just make sure you cross them over high. They wont take much bass. I run my rears from my headunit and it crosses them at 250Hz

Nevr throw away the factory speakers. You may decide to trade a 350 for a 370. I kept all the factory stuff and now have $2500 dollars worth of equip for the new Z. Soon to be installed.

6 1/2 in the door, what about the dash? is that the same?

The tweeters in the dash are 1 inch

I'm looking at going w/ Alpine Type S 2 way component in the doors. So should I get the set w/ the tweeters? What kind of mod will I have to do to make the tweeter fit in the dash?

Spend a little more and get the Type-R Component set. Look on ebay and you can get a set pretty cheap. They are efficient enough to run quite well from deck power even. You will be much happier with them. Coaxial speakers are a compromise at best. They are fine for the rears but do not use them for your front stage. Your music will sound like its coming from the floor of the car.

:iagree:- I'd almost say going with coaxials will be a downgrade from stock. The stock speakers with an after market deck will probably sound better.

I noticed with the factory base radio, when you set the fader to the rear that there is no sound. Does that mean that there is no "rear" speakers hooked up to the deck? Is there wires from the factory deck to the speakers location behind the seats? If yes, I am thinking about putting 3.5" speakers there.

would love to see this answer

DO not worry about rear speakers there is no reason what so ever to put little dinky speakers back there. Save your money and put it towards better fronts. They are a waste in the Z and with them being so small they will start distorting sooner than your fronts. It will sound 10 times better with better fronts and no rears than good rears and fronts. This has been discussed numerous times on other threads. And to the other question YES get the ones with tweeters that are separate.

As I said in another thread


Honestly in top end cars there are no rear speakers because SQ "sound quality" is setup for optimal performance. I own a civic and I have taken the rear speakers out so that way I have no rear fill as they call it. If you listen to it for a few days you will get use to it and it will definitely sound better than 4 channels. Think of it this way artist record there music in 2 channel format so the optimum way to listen to it is threw 2 channels. My setup is going to be my fronts and a rear sub that's all. After thinking about it and listening to it it sounds way better. So in a nut shell do not get rear speakers or worry about it.

The base ones are at least 2", definitely bigger than 1".

I also think that we might be able to shoehorn a 6x9 in the front door. That black plastic housing that the speaker mounts to looks like it could be adapted to fit them.

Believe me there 1 inch after cutting out them and putting a new 1 inch tweeter in its place there 1 inch. The basket might be slightly bigger.

The tweeters are *not* 1in.

The entire tweeter is 2 3/4" x 2 3/4"

The cone is roughly 2 1/4 in diameter. I have my stock tweeter & my tape measure in front of my as I type this.

When I upgraded, the 1" aftermarket tweeters required a 2 3/4" x 2 3/4" piece of delrin with a 2" hole cutout for the replacements.

that is about what I saw too.

Ya the ENTIRE tweeter holder but the actual tweeter is only a inch maybe a bit more. I mean I cut the tweeter out and dropped a 1 inch tweeter right in its place. But yes the entire holder is like 2 3/4

The base radio has 4 channel output but there is no wiring for rear speakers and/or speakers, only for the front ones.

A nice surprise when you pull the trim out and find no speaker to replace... :tup:

Plus there is no speaker wire there as well. Like I have said do not worry about them.

In the base system, there are no rear speakers installed.

Why? 6X9's suck big time! They will not outperform a 6-1/2" round speaker mounted in a door. In a trunk, they will play much lower but at the expense of sound quality.

FYI the Bose has 6x9s in the front with the 2x2 tweeter in the dash. The rears are 3.5 inches with maybe 1.5 inch dept. and maybe 3/4 inch magnet with just barely enough room to fit. I would urge you not to spend money on the rears. Totally not worth. You can't even hear them where they are located.

I replaced my bose 6x9s with Focal Polyglass 165VRS. The Slims aren't needed you have plenty of room with a spacer but that's what they had in stock and they sold them to me at the same price.

Actually not true with today's manufactures making better and more stable cones in 6X9's there actually just as good as 6 1/2. I would not go and say they are better but they are sure better than they use to be. I would stick with 6.5 though

Well thats good to hear because there is a significant displacement difference between a 6X9 and 6.5" driver. They are pretty close to an 8" if I am not mistaken.

speaker size
 

3.5 is the size for the back speakers...I just had a pair of Infinity put in.
:O)

Sorry to sound stupid so the base system has no rear speakers just the holes cut for them?
so there are one in each door and the other two or in the dash? One question if i start with speakers first what kind would you suggest for the doors. Thanks

I started at crutchfield cuz they could tell me what would fit. Did Focal Access 130 A1 components.(5 1/4") Sounds way better than stock speakers.
Cut the cones out of the stock speakers and used em to mount the new ones. Same with the tweeters. As for the rears I havent done those yet.

Thanks i check those out

In the base model with the sport package it looks like the car didnt come with the 4" speakers behind seats. Does anyone know if the wiring for the speakers is run from the factory?
