You know why they call this a fire truck? Because this truck is fire. We
set out to make this the party bus of fire trucks. And I got to say, we more
than succeeded. I'm talking 27 speakers,
1,620 watts of power, and of course, full
Dolby Atmos, making this the best Fire truck for music, movies, and yes, of
course, my friends, games. That last bit was key for AMD, who sponsored this
video. Now, all we got to do is show you how we
did it.
Good gravy. I approached this project with one goal,
to have the first ever Dolby Atmos fire truck. I thought we were putting like
car speakers in it. This is a whole ass home theater. Yeah. Where are you going
to put two subs? We're getting a bit ahead of ourselves, but yeah, we have
about 1,600 watts worth of speakers here. 27 of them to be exact. And uh
it's going to rock. I don't even know where to begin with you sometimes. This
is a better AV receiver than I have at my house. Well, it's going to be in your
fire truck now. Do you want to look at the doors for a second? Sure. Yep.
That's a door. All right. Yeah. To answer your first question about why we
didn't just use car audio speakers, it's because those require, you know, a door
to be, I don't know, like this wide, something like that. Most car doors are
like 8 in or so. Oh, wow. This is not.
Yeah. The If you look, the usable door card for this is uh that thick. Oh, I
had no idea. Yeah. So, there's just literally nowhere to put speakers on
this. And also, even if we did,
it's not going to sound like trash. Yeah. That would sound terrible. That's
why we're using the KEF T series. These are very nice speakers, but also very
thin speakers. Oh my god, Alex. Those I
can figure out how we would mount this. Where are we supposed to put this? Why'd
you get so many of the big ones? I asked Ke for all the little ones, but it turns
out they only had the big ones in stock. So, these we got special ordered in. And
the rest are all going to be huge. It's going to be so funny.
Oh, I think I'm picking up what you're throwing down, though. Yep. Right there.
Right. Right there. Right up here. Of course, that's only
three channels so far. To get the full Dolby Atmos experience, we're going to
need surrounds. And we're also going to need heights. Are you planning to
ceiling this? Yeah.
I'm thinking maybe here for the surrounds just on the back here. Well,
those are the rears. We could have rears and surrounds. Yeah. Yeah. So maybe they
can go like back here for the most like differential rear fill. Oh, okay. Well,
in that case, we could just go like that, too, then. Oh, I guess so. Yeah,
like they can just go right here. It doesn't even matter cuz we already have our sides, which is all fine and good,
bud. But where the devil are you planning to mount these subwoofers?
They're not compact at all. No, it's
going to be a problem. I originally wanted the 10-in ones that actually kind
of make sense for the space, but Ke were very insistent that the 12 is much
better and will deliver much better base for us. So, you got two of them. I have
no idea what he's planning. Like, a lot of the time we've reviewed the script
and pretty much aligned on the plan.
Where the hell is this supposed to go? Did AMD sponsor this video? They did. I
see their sick Ryzen AI Max 395 Plus
processors here in this Asus RG FLZ13.
This is actually going to be a great pairing for our system, allowing us to
game in an incredible form factor right
here in the front of the fire truck with our surround sound setup. So, we'll get
to that a little bit later. First, I
guess this goes back here. I wouldn't describe anything we're doing as a good
plan, but it does seem to be a plan. Of
course, all of this so far is in theory.
We actually have no idea what's under any of these panels. Is the cabin heat
handled by just plumbing engine coolant up here and blowing it through a heat
exchanger right there? Pretty much. Yeah. So, so where where are these
plumbing lines going? They just go, I guess. Yeah, they just go. That's why
this has this piece, Alex. Oh, it's a shroud here for the plumbing lines for
the cabin heater. Brilliant. Oh, and we can probably just put all our wires
straight up through there. And then Yeah, we can. Super easy. That's awesome. Okay, he's just going ham. He's
gone ham. He's gone ham now. So, it looks like that the construction is this
stuff, some foam, and some plywood. It's all glued together, and the plywood is
what's screwed in. So, if we want to get it down, the plywood gets ouched, which
I think I'm okay with. How is that the conclusion you're
drawing? In a lot of cars, the quality of your
components of your sound system matters a lot less than just simply how much
you're able to treat it. Like our amplifier here has 0.08%
harmonic distortion. That does not matter at all if everything is rattling
all to heck. So, we're going to take everything apart, sound deaden as much
as we can, and hopefully it won't sound like, well, a big old rattly fire truck.
Turns out the inside of the doors were completely covered in wax, which is good
because it prevents rust, but it's not so good if you want to add sound
deadening cuz I would need to spend the next 2 days doing that. So, instead,
we're only going to sound deaden the interior door panel, which probably will
get us most of the way there anyway. The first thing you want to do when you are
sound deadening is just to clean everything off. If you have a bunch of
dirt underneath your sound editing, well, you won't have sound editing very
long cuz it's going to all fall off. The sound deadening is just some rubber with
some aluminum foil on the back. It is really important to wear some cut proof
gloves when you're doing this. For a large sheet like this, I could probably
get away with it, but when you're getting it in little nooks and crannies,
this aluminum tape will cut your fingers and it will hurt a lot. Once you have
the panel roughly a fixed, you want a roller like this so you can go through
and make sure it's all super firmly attached. Even just covering a bit of it
should make a really big difference.
Yeah, you can you can really hear it already. I really like to make sure that
I cut out more than I need to so that hopefully the bit that is left over will
be useful somewhere else. You don't need anywhere near 100% coverage. Just
putting a little bit on here will make a huge difference. All right, how does it
sound now?
Oh yeah, that is way better. There's no more ringing. This is going to sound
awesome. With the doors nice and sound deadened, I want to turn my attention to
the roof. We're going to be putting enough bass into this that I suspect
we're going to be pressurizing the cabin at very low frequencies. So, the whole
roof, I think, is going to start shaking a whole bunch. To fix that, more
sound deadening. One bonus of all this work is the sound deadening is actually
a pretty decent insulator. So, it should be able to stay cooler in the summer and
warmer in the winter. Very nice. After hours and hours of cleaning and adding
sound deadening and taking stuff apart and putting it back together, the last
one is ready to go on. I did a little bit of math and guess that we need 72
square ft. Freaking box is empty now. Nailed it. This is
going to go up and then we can start actually thinking about speakers. To
attach the speakers to the fire truck, I need to make a whole bunch of little
jigs so I can have accurate holes, know that they're going to be centered, all
of that good stuff. And I was able to do the entire process on this wonderful
little laptop right here, the HP ZBook. This guy right here has the AMD Ryzen 9
AI Max Plus Pro 395. The name could use
some work, but man, the chip could not cuz I was able to do full solid works in
here. This right here isn't a super complicated model, but I was able to do
it. Then pop over to LightBurn. I have full control of the laser just on this
little laptop. Has USBA. Love that. And
now I can just throw this onto the laser. And boom, we have our guides.
It's finally time to start attaching some speakers. So I'm thinking this
one's going to go right about there. So
I can place it just like that. And then
figure out where my template needs to go. Right there. Now, one thing you
might be thinking is that this speaker would sound better if I was to turn it
so it was facing directly at me. But that isn't so much the case. You will
get the flattest response out of a tweeter if it is pointed directly at
you, but you will also get the largest change when you move around if it is
pointed directly at you. So having it like 20 30° off here should mean that it
will be very consistent sounding everywhere that your head ends up going.
Before mounting each speaker, we are going to want to first add a little bit
of foam tape on the outside just so it doesn't rattle around on all of the
metal crap that we have. And one final step before attaching it forever is just
putting on a little bit of loom tape. This stuff is just really good for
vibrations and stuff like that. We don't want this hole right here slowly wearing
a hole through our wire and killing our whole sound system. First speaker is
attached. How solid is it? fire truck going over some bumps.
She's not going anywhere. Beautiful. For speakers like this one right here, I
originally had a bunch of inventive ways using 3D scanning or 3D printing and
whatever. Now, I'm just going to drill some holes straight through the truck.
There's now a hole in the fire truck. A
yeah, not going anywhere. It is subwoofer time. Finally. Now, we did
have to spend quite a bit of effort beforehand to make sure that things just
didn't squeak a whole bunch. The stupid
fake leather that's in there loves just being incredibly loud. What we ended up
doing is adding in some foam on the bottom and then this sort of felt stuff.
We didn't do the best job attaching it, but you're not going to be able to see it anyway, so who cares? To mount the
subwoofers, we're going to be going into them through this hole right here. That
did mean that I have to take this little access panel off. And also, we had to
take off the oxygen tank holder from these seats. It looks something like
this. And man, getting it out was some
difficult from the factory. A bunch of the screws in this thing are just
pre-stripped. So, that was fun. I could have avoided doing this by simply having
this panel be anywhere else, but I really wanted to have it in the back
because I am really concerned that people are going to get in, see these
dials, and just start playing with them. I want to tune this so it is excellent
in the truck. So, if someone comes in here and starts playing with the
crossover knob, all of my efforts will be gone. That way, we can have this in
here, put that stupid oxygen tank back in there, and no one will touch it.
Don't do it. If you do it, I will be really mad. I'm very sorry about this,
Ke. Uh, you sent us these speakers and I hope that you knew that this is what
you're getting into.
Oh man, she is solid. That I can see it
flexing on the bottom. Oh, like you can see the truck flexing. Yeah. Oh, hell
yeah. With the headliner attached, we can plug in the speakers. Our
polycarbonate speaker mount can then get attached and then full send a self
tapper into the roof. So it can never come off.
Why is there nothing there? We're putting a hole through the roof.
Always make sure to debur your holes. If someone touches it, like everyone will
be when it's up here. You don't want them to get cut.
Finally, we have to attach the speakers that are going to go in the front. One
thing that's fun about this is our center channel speaker will become
structural to this truck. It is going to
be holding together the right and left panels. And you will not be able to take
them off individually after this.
This is so silly. And it's wired up.
Look at this beautiful thing right here. Just going to turn it around and then
with any luck, we're good to test it. I did wire 120 volt in underneath the
receiver, but for now we're just going to use the wall. We don't need to turn
on the fire truck and idle it for all of our testing. Moment of truth. Does it
hit?
This is going to be ridiculous.
Oh my god, the subs are so loud. You can
feel it just in your chest. It is right beside you.
She works. It's a beauty. Now we just need to get her tuned and it's going to
be sick. After a quick tune and an allout brawl
with Windows sound settings, we have a fire truck with a sound system. I can't
wait, dude. I can't wait. This is amazing.
I can't believe how clean it looks. I
got to ask these height channels. These got to be at like minus35 dB off of the
reference volume. Like come on. They're right there. I don't know. I just did
Direct Live and freaking figured it out.
Dude, I got to hear this. Well, but you
haven't even seen the AMD integrated
tablet laptop thing. Oh, no way. No way.
Okay. Who designed this 3D printed mount? Rob. This is so cool. So, like
Okay. Dude,
you play your music like that and you're like, "Oh, no, no. I got to operate my
sirens, bro." Just like that. It turns out in Windows
you can also have full Android automotive. You like run a server off of
your phone and it just like really? Yeah. No way.
Yeah. Like you have like maps here.
Dude, this is not even stupid. No, it's
sick. So everything still works. We have
full Dolby Atmos. We have flipping Android Auto, which wasn't even one of
the goals. And the whole thing is so
tidy that we can still operate the truck completely normally. None of my view is
obstructed. Oh, okay. That back window maybe a little bit, but come on. Let's
subwoofer versus rear window. We all know what we're going to prioritize.
This is nuts,
dude. You can feel it. It turns out if a sub's this far away
from you, you can really feel it. And with like with like these bouncy seats
like Yeah, buddy.
I have some disappointing news for you, Alex. What is that? We've peaked.
Nothing can ever be cooler than this again. We could put that 18-in sub in
here. Okay. The thing that stands out to me
most though is not even like how big the bass is or whatever. Obviously, any
idiot can put a gigantic subwoofer in a car. We all know that idiot, right?
Hey, mine sounds great. But that is
exactly it. What stands out to me is how not actually acid sounds. It sounds
awesome. I'm really impressed with these flat
panel speakers, too. Oh, yeah. I I have no idea what I was expecting to be
honest with you, but not this. You have to imagine pulling up beside someone at
a red light with the window down
in this car.
Absolutely bumping it.
Oh, that's so good. This is crazy. Okay,
I think I'm over headphones. I was the kind of guy back in my teenage years,
early 20s, who literally had 5.1 surround around my desk at home. Alex, I
think it's time to go back. Oh, 100%.
Near field speakers like this, I hadn't tried this in years. Not with modern
processing.
This is insane.
I owe Alex and the team an apology. I did not believe in this project. I
thought it was going to be like her her, you know, whatever.
It sounds sick. I'm trying to think of a
setup that I have listened to in memory
that sounds better than this. I can't come up with one. Have we gamed on it?
We haven't. Oh, I feel like we got to It has Stricks Halo. You can game. You can
totally game. Thank you, AMD. I think Stricks Halo is lowkey AMD's best
product in like years. The fact that
this is a full fat modern gen console
grade gaming experience in this is nuts.
Everything sounds so much more epic. I
can hear exactly where cars are behind me, which I was really not expecting
with the speakers so suboptimally
positioned. I'm loathed to use the P word to
describe anything, but this may be just
perfect gaming audio. This is intense.
It's so immersive. Even though I'm on a smaller screen, it is amazing what
immersive surround sound does to an experience. And like normally the rumble
of the controller feels kind of cheap and cheesy, you know, but with that much
bass behind it, it's great for everything. You know what else is sick?
AMD. All of your guys' great ideas that
you're going to post in the comments under this video for us to continue to
pimp the crap out of this thing. Alex was pitching uh using the fold down
doors on the sides to have like TVs,
lawn chairs, like the whole nine yards
for like what? Like tailgate gaming or what?
All right, we'll see. We'll see about that one. But we're going to do something and probably with the help of
our sponsor AMD. If you guys enjoyed this video, why not check out the
unboxing where we first got hands-on with this. Or if you want to check out
some more AMD upgrade shenanigans, you can check out one of our ultimate AMD
