How do we debug a scratchy sound?
We can isolate it with the balance to a single speaker.
But is it the speaker?
Or something else?
If it's the speaker, where is a good place (other than the dealer) to get
speakers to fit a car rear deck? Are they all standard sizes nowadays? Or
is each unique?
I'm helping the neighbor's kid refurbish a beat-up 2005 Camry where I
helped her kid put in new speaker covers this weekend but the scratch sound
persisted (we thought it might have been the crud or vibration from the
crumbling melted-in covers).
The scratchy sound persisted even with the newly replaced covers.
Any suggestion on how to debug the cause of the scratchiness?
If it's the speakers themselves, are these things standard sizes nowadays?
You can swap the speaker for the one from the other side. But "scratchy"
sounds are apt to be rubbing voice coils which you can feel by pressing
on the cone with your thumbs.
There are several standard sizes. You can buy cheap replacement speakers
from chain auto parts stores. You can buy the same speakers for half as
much from Parts Express but then pay postage on them.

Then it's the speaker. I'm assuming you used both the left-to-right
balance and the front-to-rear fader so you were really listening to only
one speaker at a time. If there is a problem in the left channel, it
will be heard in both the front and rear speaker.
The dealer is a terrible place. Do they even sell speakers?
Crutchfield. Very reliable. Very helpful on the phone with real
people. They're in Charlotte, Va. and I'm in Baltimore and I ordered
something and I wasn't in a hurry but I got it the next day.
I recommend them highly despite that they did make a mistake, like other
vendors do, wrt the inputs on my 2005 Solara radio. This is the E7001
radio, but I don't think E7002 is any different. These are both
Navigation radios that only hold one CD, and with some such radio, if
you press the CD button twice, it goes to the CD deck, and it does have
a jack for a CD deck (or satellite) and they sell devices that will use
such a jack for USB/AUX input. Well that doesn't work on these radios,
but they took my word for it, sent me a paid-mailing label, I sent it
back as if it were new, dropped it off at a UPS place, and I got my
refund the next day.
I've also bought speakers from them more than once in the past. No one
else has a better list of cars and their dimensions.
You SHOULD NOT MESS with dash speakers. There was a recall on
dashboards from that year and a couple others, on the Solara but I'm
pretty sure on the Camry too, and some of them have deteriorated so bad
they replaced the dash for free. My dash has a few hairline cracks,
but when I tried to lift the 3 digital gauges above the center AC
outlets, I put a tiny nick in the dash, behind the gauges. Plainly my
dash, also a 2005, is softer than when it was made. (But I'm prettty
sure it's nowhere near bad enough to get them to replace it for free,
plus the recall has expired anyhow.) I had to go at the gauges from
another direction and I did get them up, to reach the radio bolts and
remove the radio (long enough to unplug that device above that didn't
work. I had been able to plug it in from the bottom without removing
the radio.) So there is a tiny nick there
Since you refer to the deck, I assume this is really a Camry and not a
Solara, which some people call a Camry Solara. And that it's a sedan
and not a convertible, because the convertibles also have a woofer
behind the rear seat. I don't think it's even mentioned in the owners
manual or anywhere but the wiring diagram, but it's there.
For crud, I would have washed the covers in the dishwasher. It does a
great job on things like this.
Yes, but there are lots of sizes, especially when you consider depth.

AIUI, the dealers' speakers are no better than what they put in the car
originally, but it's possible things have changed. Anyoone know? If
they are no better than original, they are still useful when the
original ones have been ruined somehow.
Who is talking about ones that don't fit? I've never bought a speaker
from Crutchfield that didn't fit just as the original one did, except
for one car. I knew from the specs printed in the catalog (before the
web) that it was too deep, but I hoped magic would allow me to get it in
there (or maybe I could pound out a dent in the outside of the door!).
Indeed, it was just the depth they said it was, and so was the hole in
my car and it didnt' fit. Hmm. I'm sure the dealer would have had
speakers that fit, but I don't know that they would have been any better
than what I had.
Have you dealt with Cructchfield. No speaker I ever bought from them
used an adapter bracket, and none would be called universal. Of course
a 6x9x2.8" speaker can univerally fit every car that accespts speakers
of that size, but that doesn't make the speaker universal.
I won't be replacing my current speakers. Solaras don't use speaker
cover, except maybe on the dash. So to upgrade my speakers I'd have to,
I think, take off my entire inside front door panel or my entire rear
seat panel. After the fiasco of my last car, I'm not going to do that.
They do sell radios that require a bracket, because the face is not the
same exact shape as the original, or because one is changing from 2 or
1.5 DIN to 1 DIN, etc. But I don't think that's related.

Nice work on the grills! Yeah, the scratchiness is from either a separated

audio site (who's now expanded) with very good customer service. They can help
you replace or upgrade both rears, even saving you the measuring to tell you
the size for the specific car. I prefer the polymer or plastic cone speakers,
much richer sound. Manufacturer speakers are usually pretty good, so don't
commit to cheapies without hearing them in the car first.

Not "standard size" - they are often even different from mdel to
madel in a brand, or year to yrear in a model.
Try scrapyard? Otherwise dealer is best bet. There are kits to put
"standard" speakers in, but they are not terribly satisfactpry. O have
installed non-OEM speakers by making adapter plates - basically not
worth the hassle.

Thanks for all the advice - I haven't touched speakers in decades!
I like the ideas of:
a. Testing with a separate speaker (if I can find one)
b. Testing by jumping the wires (shouldn't be too hard).
At this point, I'm trying to figure out what size fits.
Here is a picture of the topside of the speaker when we replaced the grill:
Here is the bottom underside in the trunk:
The kid is at college so she only comes home to the neighbor sporadically
so I'm just lining up my ducks now.
Looking at the advice to call Crutchfield, they seem to be good and bad.
They were very helpful. 1.844.298.3430 About $50 for two speakers.
The problem is *every* speaker they have for the 2005 Camry doesn't fit.
The guy was helpful and said I had to make my own bracket. Huh? Why can't
it just bolt in? (I'm glad I asked because I didn't expect that.)
Amazingly, they have 200 speakers they say that fit, of three sizes:
5-1/4, 6-1/2, and 6x9 (I didn't think to measure it unforutnately)
I don't have the car in hand, but apparently there are three types:
a. With navigation (she doesn't have it)
b. With JBL audio system (I'll have to ask - probably not)
c. Without both of those (this is probably what they have)
I called the Toyota dealership and gave them the VIN where they told me
their price was $298 for a single OEM Pioneer 6x9 speaker + about $30 tax,
so, since I'll likely want to get a set, that would be $660 for the set.
I just can't pay that. Even for a nice neighbor's kid.
It's just too much.
Since Camelback Toyota in Arizona usually has the best prices, I called
them and they told me, from the VIN, that the radio is a "Fujitsu 10" and
the speaker part number is 86160-AA450, they sell for half that price, at
$300 for the set.
It's back to Crutchfield I go! :)

Price is never an indication of quality - it's just an indication of what
other people are willing to pay - which - marketing knows - is highly
influenced by marketing garbage.
So, a 6x9" 20W $5 Parts Express speaker might or might not be as good as a
6x9" 20W $300 speaker at Toyota which itself might or might not be as good
as a 6x9" 20W $25 speaker at Crutchfields.
How are we to know?
Sure, in the days of yore, we pored over those 3db power:frequency curves,
from 7KHz to 20KHz on each speaker box, and where, folks like Jeff
Liebermann would know, they always find a way to lie a little bit.
While I doubt the $300 per speaker at Toyota is a fair price, how can I
tell, a priori, if the $5 speaker at Parts Express will be as good (or bad)
as the $25 speaker at Crutchfields?
Is there any way for a consumer to make an intelligent speaker decision?

A good indicator of quality is magnet mass. If it has a tiny little
piddler of a magnet it will not handle any power - particularly bass.
Then lookat the cone material, and the surround. The spider is also
important- The basket is less critical - but in a large powerfull
speaker the basket will be MUCH solider than on a cheap-ass speaker.
If youfind a speaker with a cast aluminum basket you know you are
looking at a higher quality speaker - and if it is stamped steel, the
heavier the better.
Poor suspension spiders and surrounds will let the voice-coil scuff
on the magnet core - which makes a speaker rattle. A flexible basket
can do the same. The surround compliance is different on a speaker
designed for an accoustic suspension box than for a bass reflex, or an
open baffle like in the average auto rear deck. Toyota actually used
accoustic suspension on some of the "premium" sound systems years ago.
LOTS of things you can look at.
I have a pair of OEM Toyota speakers from the eighties sitting here,
as well as a pair of speakers from a Zenith TV of about the same
period - virtually the same size - and the Toyota speaker is
significantly heavier. Thicker cone, thicker basket metal, and more
rigid design - as well as a MUCH larger and stronger magnet, The
Zenith also uses an "m"formed paper surround, while the Toyota uses a
rubber surround. I've got a "tin ear" but even I can tell the
difference between the two.
The drivers in my AudioResearch towers are MUCH heavier than my
no-name set too - and I replaced the foam surrounds that had totally
"disolved" from age with new high-quality synthetic rubber surrounds -
on both the active and passive 14 inch cones.
In automotive speakers the basket rigidity is more important because
of the "G" forces experienced when driving on rough roads. The cheap
speaker might sound good when installed - but it may be pretty auful
two years later.

My guess is that for an automobile speaker, it's important that it be const

They're all dreadful. It doesn't matter which one you buy, it will be
dreadful. So buy the cheapest one or the most convenient one and don't
worry about it.
No, because it's basically not possible to get decent sound in a car anyway.
And even if it were, it wouldn't be possible to do it with the typical
full-range whizzer-cone speakers that we're talking about. So buy the cheapest
ones you can get and it won't sound any worse than it did when the car was

That's a good idea to wiggle wires (I haven't done speakers in years).
The car is at college so it only comes home to do laundry.
When it comes home, the neighbor will call me and I'll be ready.
What I'll do is:
a. Try to find a test speaker of about 20 watts
b. Make a set of jumper wires to jump one side to the other
c. Wiggle the wires to see if the speaker or the radio is bad
