The rear speakers in my celica have been blown ever since I got it, but my searches did not come up with any information on how to replace them, how to remove the quarter interior trim, or even what size they were.....


So. My wife and daughter were out of town last week, so I did some exploratory surgery, and replaced them. Here's what I found. If you have a convertible, and have worked on it at all, you are probably familiar with the coach-built quality of these, so there's a decent chance that some of this will be different, but it's probably pretty accurate.

Tools: Philips screwdriver, flathead screwdriver, trim stick (careful use of a flathead acceptable), 10mm socket, 12mm socket, maybe 14mm socket. (obviously I did it with an impact driver, but hand tools are just fine).

I did this with the top and windows down to really make it easy to get at everything, but most of it could be done with the top up.

Fold the back seat down, and un-do the 2 12mm bolts to remove it from the hinges:

Pop the back of the sill molding off and pull it off to one side (doesn't have to be removed completely, but the back overlaps the quarter molding).

Remove the rear seat base. It's just clipped in at the front, and then will lift free.

Then gently pry the speaker grill off.

There are 5 larger phillips screws in the interior side of the panel (one behind the speaker grill, 2 covered by the seat bottom, and 2 by the seat back (one of those is hidden behind the hinge in this picture))

Remove the 4 10mm bolts that hold the seat hinge and latch on, and remove them.

Pry the little cover off the 3 smaller screws on the back edge of that panel:

And remove them:

Then to the top edge of the panel. There's a screw hidden by the front seat belt:

There are 2 snaps (presumably for the hard cover), the outer one is just screwed into the plastic, but the inner is screwed into the structure of the car, and will have to be removed.

For the last 2 screws, the top will have to be folded most of the way down (or part of the way up).

Then the panel lifts off pretty easily. Then it's just 4 screws that hold the speaker to the frame. It is glued in, as well, so will take a bit of prying, but not too bad.

I used these 4" speakers to replace the old ones:

They were a direct fit. The screws lined up perfectly, and the wiring was an exact swap.

I'm extremely happy with the results. I'm no audiophile, so they're probably not the greatest thing out there, but what do you expect from a 4" speaker?

I'm going to have to tackle this sooner or later.

Is it possible to pull off the grill, and cut the plastic panel around the speaker just enough to allow removal and installation?

Thank you so much for this post. I really thought I'd have no luck finding this information. Do you have any other good information on the stereo system? I'm starting with the rear speakers (took of the square cover) because they are obviously rotten on mine. I was under the impression that there was an issue with the amp under the passenger seat so I might have to do some other work to get a working radio. Since it looks like such a pain to get to those back speakers though I'm going to replace them since I know for certain there blown and go from there.

So, I want to replace mine and it looks like there is plenty of plastic that can be trimmed away so the speaker can be removed through the hole, has anyone done it that way?

Dddaringer I just replaced the head unit on my 91 convertible, if you have the one piece CD/cassette player I can save you a lot of time and make the replacement a breeze.

I just did some exploratory surgery and even if you were to cut away the plastic down to the lip where the grill cover hides you still can't get at the screws that hold the stereo in. Looks like removing the panels is the only way to swap the speakers.

Thanks for taking the time to post this, I used it today as a guide and replaced my rear speakers. Went really smooth, start to finish about 3 hours but 2 of those were on the first side, the second side went much smoother.

I put in 4" Rockford Fosgates and they sound awesome. I replaced the door speakers earlier this week, just got to do the dash speakers now.

Thanks Again,

Mario

Hello,
Very usefull. I am going to try it myself, but plan on repairing the original speakers, if possible.
Best regards

Hello,
Most of the pictures I've seen of the interior of fifth generation Celicas show the dash cup holder fixture ajar. Is anybody out there who has been able to fix the problem?

What model speakers?

Great post thanks - can now finally replace those blown speakers ! Will this panel removal also reveal the front seat belt mechanism ? Have posted a seperate thread on this for help ~!

I'm going to try and save the factory head unit. I'm going to replace all the speakers first. Has anyone had to replace the small subs under the dash yet?

It seems a plastic clip that has broken (I have the same issue). If you replace the stock radio head unit I think you have to give up your cup holder.

I actually managed to somehow have bought the most perfectly sized double din unit because it not only perfectly took up the length of the hole in the dash, but left exactly enough space in the height for me to insert the cupholders. Now the whole thing is in with a big ol' hole in the dash. I'll try to post a picture of it at some point, but I'm new to forums as a whole so I need to learn my way around these posts.

Also, I didn't realize it would be a hassle to get back there. I had pulled off my rear trim entirely to expose the bare metal because I wanted to install a harness bar, and since our convertibles don't have B-Pillars, I had to weld in some steel bars that could act as my B-Pillars and be solid enough to actually reinforce the chassis. It was actually a ridiculous pain in the rear, but I'm glad I got it done.

On another note though, my door speakers don't work at all. I replaced them and still nada. I used an official harness adapter after trying to hardwire it using the original harnesses, and nothing worked. Every other speaker works though, even the tweeters. I'm garbage at anything electrical. Engine/tranny swap? Sure, as long as they have premade harnesses. Custom chassis fabrication? I'm down. FWD to RWD conversion? Months, but done. Trace a wire to find a short in a 3 foot long system? Yeah, I'm gonna take it to a professional. My soldering is at a 4th grade level at best. Honestly though, I think that my amp is bad, but I have no idea what amps do or what the point of this one is. Do I replace the whole thing? Is it salvageable? I feel like an old man asking these questions but an old man would definitely know the answers. I'm 22 so I'm too young for experience and too old for excuses lol.

What is your advice on head unit replacement? I hear the wiring is a hot mess.

The factory radio and amp are a wiring nightmare.
