More of a confirmation than anything else - the front speakers on my '88 N/A model are 10cm, which i guess is about 4".

I fitted a pair of Kenwood KFC-1050's this afternoon at about 20 mins each side. Pretty good considering they only came to ?20 :D

Speaker sizes
 

According to Crutchfield, the fronts are 4" and the rears are 5" ..BUT they don't make 5" anymore, so you have to get 5.25 and cut the plastic OR get 4" and adapt them somehow. I am looking to replace my speakers as well... I just measured and I get about 4" in the front and 4" in the back ('87 MkIII NA). So will give it a shot and let you know... :-)

subs in the mk3?
 

Did the mk3 come with subs? I was taking out my rear speakers and I noticed some things behind the rear seats that kind of looks like subs. They're pointed down, towards the road. My car was fully loaded back in the day, so if there was an option to buy subs, my car has them.

If they're not subs they might be something with the TEMS system?

Subs
 

I think I know what you mean.. those metalic things you see when you lift the rear deck cover off? I think those are part of the TEMS system.

the front doors can fit 5 1/4" no problem and possibly 5 1/2" with a custom bracket. the rear speakers are 4". if you take the trim piece around the rear seats off you will find another set of speakers that are about 3 1/2"

Hi, im new to the forum and i own a 88 supra N/A hatchback i need to know wut size my speakers are. i looked it up on google and had no luck, i just need to know the front and rear sizes that i could use without customizing anything. my speakers are old and the right side dont work most likely they're blown. thanks

the front are 4" and i think the backs are originally 5", but good luck finding 5" speakers. youll have to do either some cutting and get 5.25" or get some sort of bracket or something and get 4"

ok thanks alot

I fit 5.25s in my doors, They arent easy to get in tho. They are too deep and hit the door. There not even screwed in right now...lol. They just flop around in there.

i have mtx 5x7 in my doors. all i had to do was cut the mounting brackets a little and they fit. they dont hit the glass or nothing

My rear speakers are 6x9s. They were put in by the last owner and the job was a little botched. The housings are not tight so the bass response is pretty bad. Someone stole my radio so I haven't heard them in about 3 months, though. I think the fronts are 4''. This is a mkii... if that makes any difference.

i looked everywhere i could think for a place to put speakers in the back and i cant find anywhere. i have an 87 supra. i know about the ones right behind the seats and the door speakers but i cant find a place to mount another set in the back? can anyone get specific about this location?

the panel by the rear side window
thats where the stock speakers are housed in

the door speakers in my 88 are 3.5" but they might be different in a 89

Just thought i would show you all these 5 inch speakers. I just saw them

poo. my mom got me this Complete Car Stereo Package made by sony with Xplod speakers in it, theyre apparently way too big. two 6.5" speakers and two 6x9" speakers. and a cd\am\fm radio which im going to put in anyways...but i wanna fit those speakers in haha.

well, one speaker is replaced haha. got 4 4" for 30 bucks, yay for sales. unfortunately my dad kinda broke the power lock mechanism, the little box where the white stub on the back of the button now has 3 sides, and the two metal clips that hold the lock moulding into place have to be superglued on because the bent pieces at the end got snapped. other than that, it sounds nice :-D the other one is gonna be a piece of cake...then come the back ones.

where are the back ones anyways, and how do you get to them to replace them?

dont worry about it too much. xplod speakers are nothing great. there is a reason why there called Xplodes. You can always buy 2 6x9 boxes and put those in your trunk area. and fold down you rear seats.

what i want to know is how to get to the front speakers with out breaking anything.... other than taking off the whole door panel? do you just pop off that cover, when i start prying on it, it feels like its going to break. any info helps guys, actually i have to take it off anyways to replace that thing that stops my door from flying into another car when i open it, but for future reference is there an easier way. thanks in advance.

Heres a link on replacing your speakers. ^^^VVVVV

I'm in the process of replacing my speakers and the stock speakers i found in my 89 supra are 4 inch with tweeters in the doors, 3.5 inch in the back seat and 4.5 inch subwoofers in the boot.

The 3.5 inch aren't easy to come by but you can still find them. Those damn 4.5 subwoofers are a bit of a problem though.

can someone please tell me where the third set of speakers are located...i know of the ones behind the rear seats right up against the glass and the ones on the doors, but how do I locate the other ones...thanks

Not the best picture but you can see the stock 4.5 inch sub in the boot, the 3.5 inch speakers are at the top corners of the back seats right in front of these.

You'll need to remove the back seat in order to remove the side panels so you can get your hands on them.

weee
 

i finally replaced my factory radio to a mp3 capible cd player thank goodness.. but the crap thing is only two speakers appear to be working im excited to be getting new ones soon.. im getting 4" powerbass speakers with built in tweeters untill i get more money to get better ones and replace the tweeters i also was wondering how you would go about removing what ever part of the door panel to get to the front.. i looked in the haynes book but nothing.. as far as the back seat speakers im looking foward to that night mare

[pionneer cd player with custom mounting brackets and wiring hardness fabricated by me] YAY!

^_^

victory..
 

i have installed all of my speakers an amazing hour an a half to install all 6 not as hard as i thought.. quite simple honestly i also did some other little interior tinkering so she looks cleaner also had to replace a bunch of parts that broke due to age from my tune up she deserved [ i had oil in my spark plug bay]
basically i rebuilt the entire top in took about two weeks doing everything by myself.. it was well worth it because now i can say shes lightly modified

5. 25" or 5 1/4"

The hatch area speakers are 4.25", the backseat shoulder speakers are 3.5". Neither of these changed at any point in the MKIII production except that the pre89 MKIII's did not have the back seat shoulder speakers.

Door speakers are 4" for 86.5 through '90. '91, '92 and '93 are 6.5".

ARe the back ones 5 1/4 to?

Read my post.

Never ignore cre he always has outrageously reliable info.

Thought I'd chime in on this post. Last night I just helped a friend install new front speakers in his 1990 Supra. I can confirm that the door speakers are 10cm / 4". This car originally had the factory cd player with amplifier and 6 speakers (doors, rear seats, and hatch).

Interesting note worth mentioning, whomever installed a radio in this car before we got to it did not seem to know about the factory amp wiring, and they ultimately chopped up the harness and ran their own speaker wire. If you upgrade a factory amplified Supra, and intend to delete the factory amp, you can still perform a clean 100% reversible install using the typical 82+up wiring harness adapter found at just about every car audio shop. After removing the factory radio, disregard the harnesses plugged into it. In the back of the radio cubby, there is a wiring harness running left to right that has 2 white connectors. Unplug these 2 connectors and connect your harness adapter. You just bypassed the amplifier and have all of the correct connections for your aftermarket radio to function correctly. Now if you wish to return to the stock stereo, you can do so by just plugging it back in.

Also you won't have complete strangers cussing out your hack job and discussing just how stupid you are as they fix all your mistakes :)

That's correct the size is 4" and it's quite a common size so you wouldn't have problem choosing a fitting speaker for it. By the way, this tech article covers the speaker installation pretty good: Audio Speaker Basics
