Are the speakers actually all blown (magnetic coils shot)? Or is the foam suspension just crumbled away? If just the foam suspension, your existing speakers can be refoamed. You can get material to do this yourself. Or you can have a speaker repair shop refoam them for you.

 

Rear speakers are proprietary they are 6". Can fit 6.5" depending on the speaker, you have to cut the old speaker out of the metal frame and possibly cut the plastic housing to clear the magnet. Front speakers are 3.5". Almost no aftermarket speaker will sound good with your factory head unit. This is the closest match for the OEM rears, 4 ohm version

These are verified to fit, but again you need an aftermarket deck and amp to drive them properly

Some pictures to give you an idea of what to do

Hertz will fit if you cut the edges

 

3.5"/4" for the fronts

The speaker in the front is 3.5" but there is also a 4" passive radiator. Don't try to replace the passive radiator - there is no room for a speaker there. If you want to go bigger in the front, you will have to custom fit a kick panel or door panel speaker or component set.

I run stock location speakers 3.5"/6.5" with an aftermarket head unit. Not great, but a LOT better than stock.

There is sorta*, I tried putting in a 4" mini subwoofer didn't work not enough volume so yea keep the passive radiator. All Gen2's have the passive radiator including U.S. market models? ES250 has a ported box I thought this was maybe on some U.S. spec Camry's as well?

*almost no normal speaker will fit here.

Ive had a few of the original OE head units and they were all crapped out / made the speakers sound like they were blown.... Turned out the speakers were fine, and the head units were at fault. Threw in a cheap Alpine unit and the speakers worked fine.



There's a chance the speakers are fine (despite being like almost 40 years old)
if you plan to get an aftermarket head unit head unit, id replace that first before the speakers.
The speakers aren't hard to do, but they're just more time consuming than a regular speaker replacement as 71 said you need to do some work to get aftermarkets to fit..... assuming you want it to look nice / factory. Most people around here used to just cut some holes and shove some 6x9s out back of these 2nd gens.

As I mentioned earlier, my original speakers sound good in both my '90 Camry and '91 4x4 pickup. I have a Toyota CD/tape player with built in EQ in the pickup and it sounds really good. The cheap Alpine in the Camry sounds good but the bass is a little lacking because the rear speakers are not that big.

 

I was wondering if you had to cut those out, this makes me want to pull the extra speakers in my bad 90 just to have another set if i mess up at all, good to know so i can get back to the speaker covers, clicking in and looking factory!
