This is just one easy way to use Windows, Linux, and iOS together, to
quickly and easily watch a YouTube DIY at a location that has no Internet.
1. On Windows, I downloaded the desired YouTube DIY:
2. It's easy to transfer files into VLC over USB on dual-boot Linux:
That's it. Now the video was on iOS playable where there is no Internet.
A. I bought the tools at Harbor Freight & the speakers at Fryes:
B. I followed the YouTube DIY in VLC, step by step:
C. I removed the decrepit Toyota OEM 20W $300 Panasonic speakers:
D. I had to drill holes to fit the 450W Blaupunkt 3-way speakers:
E. Everything else but the holes fit perfectly back into place:
The only catch is that it's amazing that something as common as a 6x9" oval
speaker requires holes to be drilled in the rear deck given that these
things should simply be standard.

I've seen Jeff Liebermann's responses to questions of how manufacturers'
lie about specs, where he has personally doublechecked things like claimed
wattage on radios.
But what's amazing is that a pair of $300 Panasonic 20W paper-cone one-way
speakers sells at Toyota, when these $30 Blaupunkt 450W (claimed) speakers
are clearly better made.
The magnets alone weight a ton compared to the flyweight Panasonics -
although I don't think there is a spec on magnet heft. (What does the
magnet heft mean, in terms of specs, when the difference is striking
between two speakers?)
Also the paper of the $300 Panasonic cone is brittle and subject to sun
degradation, while the $30 Blaupunkt was presumably more sunlight resistant
rubber & foam.
But to your point on wattage, the head unit remained which likely was not
capable of outputting more than 20 watts RMS anyway - so there's no chance
that the $30 Blaupunkt speakers will be carrying more than that.
One question I have is why don't they make speaker holes standard for
standard-sized speakers? The other question is about that magnet.
If there were two same-sized speakers, one with a huge magnet and another
with a puny magnet, what does that mean in terms of likely performance spec

If you can improve on this question, let us know:
*Q: How would you download this video to watch offline on an iOS device?*
You bring up a good point, which is that the iOS tablet is the hardest type
of tablet to get to work in the real world with other operating systems.
I have an android tablet, where it's so easy to download any movie
*directly* to the tablet, that it's not funny. Almost nobody knows this
trick, but all you need to do, on Android tablets, is install the F-Droid
(don't use the Google Play app which is a knock off with ads!) free ad-free
YouTube Red clone named "New Pipe". That app is so wonderful that you'll
never use YouTube ever again, since it's YouTube on steroids, without any
ads ever, and where it can download any video or audio.
So I didn't mention Android because it's just too easy.
I don't have a Windows tablet, so I was showing folks how to do it on iOS
since iOS is always a thousand times harder than Android is due to its
walled garden nature (as everyone is already aware).
BTW, Linux and Windows plays so nicely together that it was also a no
Linux, for example, reads beautifully the entire Windows file system (well,
except for the tricky stuff Windows just added in the February Win10 where
they secretly modified the NTFS, e.g., the wuaueng.dll file as one
Given that Windows does Youtube downloads beautifully, and that Linux sees
the entire Windows disk, and that Linux plays far nicer with an iOS device
than does Windows sans the iTunes abomination, that's why I used the system
that I used. (Because it's the best of all worlds.)
So, while on Android I would have just searched, viewed, played, stripped
audio, and downloaded video using the same NewPipe app, the iOS device
necessitated a multi-step but still trivially simple process of...
1. On Windows, I downloaded the video using the extremely powerful and
super flexible command-line youtubedl.exe app.
2. Booting to Linux, I already had the results (since Linux sees Windows
perfectly), and then connected the iPad, and since Linux sees iPads better
than does Windows, I slid the file over into the VLC space on the iPad to
play it there.
If you know of a *better* way to do those two tasks, assuming the
constraint of only open-source freeware, then let us all know as we'd all
benefit from the technical expertise.

we take off parts out of order all the time, etc., where I didn't have the
luxury of experimenting while working on this neighbor's car.

I put the kid to good use by having her hold the iPad tablet, and she would
read out the next step and I would do it while she paused it.
That worked out perfectly - but they don't have a router (reminder for me
to buy them a new router as they only use desktops or cellular).
In my case, this use model was perfect:\
a. Mom watched over everything like a hawk (but she did bring refreshments!)
b. Daughter held iPad and told me what step to do next (this kept her busy).
c. I removed the fifty or so bolts and clips & installed the speakers.
When it came time to drill into the rear panel, I sent the mom and daughter
inside asking for them to make more food!

So yes, Android does everything iOS does, and then tons and tons and tons
more, while iOS doesn't do even what Android does, and iOS does nothing
that Android doesn't already do.
Hence, I agree that iOS users put up with this Apple crap ... but it is
what it is - and all we can do is deal with it if that's what we have in
To always try to add value, on Android, here's what I suggest:
Be warned that the Google Play knockoffs on New Pipe seem to have taken the
source code and added their advertising crap to that source code and then
remarketed it on Google Play - so I only recommend the F-Droid version but
if you don't want to use F-Droid, the Google Play knockoffs do work and
even they are better than Youtube is.

To continue to add value, one advantage of Linux over Windows is that Linux
actually works BETTER than Windows with an iOS device. You just connect the
iOS device by USB and slide the files over into the "private space" of the
VLC app and you're done.
On Windows it's slightly more complex because iTunes or the Apple Device
Drivers are needed (IMHO), and that's just not acceptable. At least when I
plug the iOS device into the latest Win10, but without iTunes or Apple
crapware, what shows up is not nearly as much as what shows up on Linux,
and on Linux, it's two way whereas on Windows it's only one way.
Another question I might ask here is why did I have to MODIFY the speaker
drill holes. I realize the simple answer is "you just have to". But Jesus.
It's just a 6x9 oval speaker for heaven's sake. There's nothing in a
speaker which necessitates "special" drill holes.
Why don't they just make speaker holes standard like a billion other things
are standard (e.g., USB or pipe fittings or quick couplers, etc.)?
Also, I didn't realize speakers have a +/- wire. What happens if you
Note though that it's hard to reverse them since both the connection on the
speaker and the harness connector on the car had one wire with a red stripe
and the speaker itself had a plus and minus sign and the terminals on the
speaker were different sizes and the harness connector on the car only
clipped in one direction.
So they did a *lot* of things to ensure that you don't get the wires
But what happens if you do cross the wires? (Just curious.)

It's clear that you, trader_4, understand that of the fifty or so bolts and
clips that had to come out, not a single one was visible, where it's not
always obvious how many there are or in which order to remove the dozen or
so pieces of trim and lights and grills and decks and molding and belts and
cushions, etc., that had to be removed in order to just *expose* the
speaker bolts in this kid's vehicle.
Obviously, once the speakers were exposed, the wiring was trivial, which,
even James Wilkinson Sword must note, I didn't say I had any problem with
the physical part of wiring the speakers.
BTW, to add value here, the *great* thing about the physical wiring was
that the positive and negative was so obvious in so many ways that you
couldn't possibly make a mistake.
a. The harness wires were color coded with a red stripe
b. The speaker wires were also color coded with a red stripe
c. The speakers themselves had different sized connectors
d. The harness connection itself only clipped in one way
e. The speakers had a plus and minus symbol
So, the wiring was really easy. I used wire nuts to connect to the harness
connector so that the speakers could be swapped out more easily in the
Routing the wires was also easy as there were pre-fashioned clips and
curved troughs in the back deck, which routed the wires behind the seats to
the hidden harness connectors (none of which was covered in the video but
they were all easy to find since you just follow the wires).
The speaker cutout even had a "well indentation" to get the wires from
underneath (in the trunk) to topside (to connect to the hidden harness clip
behind the back of the seats).
So, as trader_4 astutely noted, the wiring wasn't ever the problem. The
advantage of the video was simply to know where the fifty odd hidden
connections were in the dozen odd upholstery and trim panels that had to be
Plus, it kept the kid busy whose car it was.
No, it doesn't. It might make the music sound odd if you're very very very very good at hearing, or you have OCD, otherwise it may just reduce the volume slightly. Unless you have the speakers positioned perfectly and are sitting in a precise position, then the delay of the speed of sound will cause more problems anyway.
If two stereo speakers are out of phase,
they tend to cancel out low frequencies.
You get no bass. The cutoff frequency
depends on how far apart the speakers are.
If they're less than half a wavelength
you get significant cancellation.
Try this: wire two speakers this way,
set your amp to mono, and place the
speakers directly face-to-face. Most
of the sound gets cancelled.
Am I being stupid or shouldn't ALL the sound get cancelled at ANY frequency if you're sat midway between them? Imagine you're sat in your living room and have one speaker 3 metres in front of you and 1 metre to the left, and the other 3 metres in front of you and 1 metre to the right. All sounds come out of the two speakers 180 degrees out of phase. Since the distance from the left speaker and the right speaker to your head is identical, the sounds will still be 180 degrees out of phase when they reach you.
Since this doesn't happen I can only assume that either:
1) you hear the two out of phase sounds with different ears and your brain allows for this.
2) reflections off the walls mean you can always hear the sound anyway.
I've often connected speakers both ways round and never been able to tell one was quieter than the other.
If you were in one of those weird silent rooms (anechoic?) then you might not hear anything if you wired them up wrong. I saw a TV program once where you couldn't hear someone speaking if they faced the other way, as the sound from their mouth didn't bounce off anything. I guess the same would happen if you were floating in mid air, like er.... space, but with air.
Anyway, it doesn't matter, you get precisely the same sound whichever way you wire them up, I guess something just bounces.
Most of the sound you hear in any room is actually reflections.
Like 70%. So in your setup, you might get cancellation of the
direct sound, but that's only part of what you hear - and the
rest takes various paths that don't cancel.

You have an intuitive mind.
Every car is different. I've replaced spark plugs in an Infiniti where the

spark plugs (and I've replaced a lot in my cars), I've never had to lift

You just don't have the expertise yet - but you will soon.
The iPad doesn't have cellular. It's WiFi only. And if it had cellular, it
wouldn't work, since the neighbor's SIM card wouldn't even fit, let alone
work. And they are on Verizon anyway, but it still wouldn't work as they
had puny cellphones.
You don't have the expertise yet to understand the problem set
sufficiently, (likely because you have no experience with iOS perhaps?)

If I can't access A without removing B in the engine bay, I take it to the garage. I don't even change my own oil. I do however buy my own parts on Ebay. This really pisses off the garage who likes to make money on markup. I get them to do a service/MOT check and give me a list of what's wrong with it, then I turn up a few days later with all the parts and insist they only charge for the labour on the bill. If they refuse, bringing up the subject of ripoff and markup frightens off other customers and they get on with it.
Car designers never seem to think of servicing ease.
Then the ipad is a piece of shit. Use whatever phone of yours or theirs has cellular access.
I avoid IOS because I know it's rubbish.
Stop using an Ipad. Surely there are normal tablets (as in non-Apple) that can access the cell network?
