i wanna know what size speakers go in the door panels and dash in a 91 coupe? i think they are 4s but not sure, just wanna make sure im buying the right thing.

 

4.5 in the dash (most 4" speakers will fit).

6 inch in the doors.

you may wish to seach next time

 

I fit 6.5'' in the doors and in the rears. You will most likely need a spacer for the door or it will hit the window track. If you use 6.5s in the rear you will probably have to do some custom bracket to make them fit.
This is what I had to do in my old 91 and they were infinity kappa 6.5 inch speakers by the way.

 

Infinity does market their 6 inch speakers as 6 1/2 inch and their 6.5 inch speakers as 7 inch.

 

I have oversized 6-1/2" in the door, and as mentioned they required a 5/8" spacer ring (3/4" was too much).
1" tweeters up on the dash in the corners and 4" speakers in the stock dash locations. Out back for rear fill I replaced the tower speakers with 6-1/2" coaxials.

Comming soon, a 10" sub mounted in the spare tire compartment to fill out that bottom end

 

Where can you get these spacer rings from?

 

circuit city, best buy, any stereo shop. for about 12.99 a pair.

 

Wait... there's speakers in the dash? LOL

I have a 89 GTU.. I don't think I have the speakers in the dash. Do I?

 

I think the stock speaker size on s4's is 5.25 so i picked up some fosgates and put them in. Ive got a pair of 6.5 pioneers and test fit them before and they were too deep(hit the window) but they seemed to fit in the hole circumference wise.
ive got a s4 vert and would like to put the larger pioneers in....so i can get spacers from best buy or something like that?

with the spacers will they fit behing the stock speaker grill ( the square one just above the door armrest)??? It looks to be too small.....

 

Thanks.

The dash speakers are by where your knees are if you have them, by the hood pull latch and right under the glovebox.

Also, I would remove the stock grille and use the grilles that come with the speakers.

 

so in my 91 s5 coupe i can fit infinity 6 1/2 inch speakers in the doors just need the 5/8 spacer

 

I went up to best buy, they only had 1/2 and 1 inch spacers. I got the 1/2 inch ones. They were 12.99.

 

do you know if they work yet

 

i fit 5 1/4 in the dash, i had to do some fancy customizing though!! looks good to!!

 

Im not sure if they're gonna work yet. Ill find out tomorrow.

 

since we are on the subject of speakers im going to be putting infinity 6000cs 270 watt 6 1/2 inch speakers in the doors since im doing this would it be a good idea to take out the speakers in the dash since you wont be able to hear them over the door speakers also when i put in subs would it be best to take out the rear speakers because you wont be able to tell they are on

 

IMHO id take them out. They'll probably make you infinitys sound worse. Are you new speakers 1 piece or components?

 

what exactly do you mean by 1 piece or components

 

I bought cheap walmark speakers and made them vit my vert...the one on the driver side dash doesn't fit and i haven't decided what i'm going to do about it yet. I'll probably go buy smaller speakers soon.

 

Are they these: 1 piece total, a woofer with a tweeter (or two) in the middle of it:


Or these: Components usually a midbass, tweeter, and crossover:




I also found out the spacer rings I got from best buy do not work, because the ring is closer to 7 inches around, and because of crevasses moulded into the door does not sit evenly so youll need some other alternative. Mine fit fine in the door, and theyre 2 1/16 deep. So if you stay < 2in deep you'll be ok.

 

S5 panels dont work on S4's do they? .... its like there is noprecut area for the speaker to rest.

 

When I went to the local stereo shop they stuck in the 6.5 speakers and left the stock grill on. He said the new one would not fit. The speakers sound Great! I have a 10" sub in the trunk and I think I am going to upgrade the headrest speakers and add another amp to drive them. Anyone have the lowdown on taking the headrest apart?

 

I fit 6" speakers in my dash. Don't ask questions.

P.S. I have those infinities with the tweeters in the middle pictured above. They rock.
