Default JBL Center Speaker Opening

Hi folks. I am planning a special installation of a CB or HAM speaker, into the speaker opening that in the middle of the dash.

I believe this speaker is only available with the JBL option for 4Runners.

My dash does not have this opening. I looked on the inside of the dash, and it seems to have the cut-out marked, for the installation of this speaker.


I purchased the speaker grill, from the dealer.


What I need to know, is:
What does the opening look like?
What does the grill snap into?

Does anyone have any images of this speaker opening?
It looks like the grill just snaps in; could someone pop theirs out, and post a photo of the opening?

Brian, I can try to take my cover out and see if I can make a picture of it.

How much was the grill? I would like to do the same when I get a ham radio.

The grill was $41 total. It should make a clean install.

Thanks Alex.

From the pics, it looks like it just pops out, like many of the dash panels do.

Anyone else already have pics of this?

I'm still not sure what would be the best way to cut the opening.

I run down to the garage and took couple shots. I hope they will help you Brian.
Basically its rectangular cut of the dashboard cover and rhomb cut of plastic underneath it.

Perfect!! Absolutely prefect.
That is exactly what I needed.
Now I know what I need to do.
I will take pics as I go, to show how this mod works.

THANKS Alex

Note: I see you have your GPS and XM antennas on the dash. If you look in my first photo, you will see my GPS antenna attached to the air duct on the right. The factory GPS antenna is under the dash, near this point. The plastic dash does not interfere with the GPS signal, significantly.

Default Here we go

This won't look as good as the factory-cut opening in the dash pad, but it looks like a factory job, when the grill is installed.

Open up the dash, and remove the stereo head unit. (Tech write up)

Looking up, at the bottom side of the dash, you can see the location where the factory JBL speaker is installed.

Take your knife, and push it through the four holes, that the grill will snap into.


Yes, that is a knife blade sticking out of the dash.


Then cut the top surface of the dash, between the four holes you just made in the dash. The cutout should look like a square. This is a little un-nerving, to be cutting a huge hole in your dash.




Now peal the faux leather off the foam padding.

Next, I cut slices, like bread, through the foam, and started pealing it off. It works best, if you use the knife to get under the foam, and slightly pry it up, a little at a time.

The next part is the most difficult. So much so; I couldn't get any photos. Looking up under the dash pad, use your knife, to cut around the groove, in the plastic. This groove is the opening, for the factory speaker.


Here it is, all cut out. The foam makes a crummy mess.


This is the piece that gets removed.


Now, using the speaker grill, make a template, and use it to guide your beginning cuts, that will widen this opening, in the foam pad.


When I layed the template on the dash, I started by cutting half way between my original cut, and the template.

Clean out the 4 holes, for the grill to snap into, and set the grill down in the holes. This will give you an idea, about where to cut next.


There is a lip, around the inner edge of the grill, around the 4 pins. The opening must be large enough to allow this to settle into the dash.


Keep trimming, a little at a time, and make sure you keep picking the foam out (it is glued to the surface), to keep the space completely open for the grill to fit in. I smoothed off the rough edges, once I had everything fitting properly.

Here it is, all snapped into place.


It started to rain. How typical.


This is the opening, viewed from underneath. I really did smooth the edges, before I was finished.


The next step will be to install a speaker (not the $125 factory speaker!!), for the CB or HAM radio.

Thanks.
It is really scary to cut through that pristine dash pad.!

But it looks just like a factory install, when complete.

Great job, Brian.
That looks exactly like my OEM center speaker cover!

I'm planning on using the hole to store 2 12V accessory cabls from 2 GPS units. I'll pull out a short section and plug into the GPS as needed for excursions and bury them back when not in use.

Thanks guys.

It was very satisfying, and a relief, when it snapped into place.

I looked at the repair manual, to see if I could remove the dash pad. It appears to be part of the main dash structure. Everything would have to come out. Unless someone know different, that is what the shop manual shows.

So; I just pulled out the center section and stereo, and was able to do it that way. Cramped quarters; but do-able. The dash is closeto the glass, so a short (and sharp) knife would better than the knife I used. Once you open the hole in the dash, the crums start falling down into the space behind the stereo. A lvacuum (with a hose) helps with keeping the foam crums cleaned up.
