Match vehicle panels perfectly - Making the False Floor! - ProjectStealth

To cover my amplifiers and subwoofers for this car audio project I will be making a false floor. This trunk design is meant to be stealth so the false floor serves as a foundation for the beauty panels and other design accents that will highlight the gear, yet be a usable floor in the vehicle for groceries or other items when needed. #cafprojectstealth

[@giovanniciardiello951]

Hi Mark, I really like your work! I work in a car manufacturing facility and I would suggest you to do some crack lines on the wood panel to avoid it being dangerous in case of crash, this way the panel will break into pieces instead of shooting in the front. Keep up the good work! :)

[@leonardo9259]

@Oakley Lewis ur right bot, nobody cares

[@leonardo9259]

@Henry Declan begone BOT

[@furhadnasserjah123]

id rather have it shoot in the front than to have all my hours of hardworking break on purpose

[@Flashbang_Photo]

@@furhadnasserjah123 I'd rather survive ngl

[@CarAudioFabrication]

I'll be cutting the holes for the subwoofers and amplifiers and building the rest of this beauty panel in an upcoming episode! Don't forget to subscribe to see the rest of this build! For those of you wondering if the beauty panel makes a difference for the sound watch this video here: kzbin.info/www/bejne/qnqUgoCAmc2dq7c Thanks for watching! :)

[@ThonotosassaBoys]

Since the majority of custom car audio is more than just 1 basic sub, Why dont you do some more complex tutorials/discussion vidoes for the spl. Cabin bracing, go through 4th orders and 6th orders, blowthroughs, flatwalls, lithium vs agm, explain woofer specs like vas qs xmech, Korean Brazilian and Chinese amps, competition classes and metering, etc.

[@jeremys8360]

ekim andersom spl is diy

[@slow_rednline4874]

@ekim andersom that's not true

[@jameselam8263]

Depending on the vehicle, sometimes I use the factory carpet to trace my false floor shape. I you make a matching access panel on the other side you could cut out the middle of each and make another insert that is covered in speaker grill cloth to vent the sound from the subs.

[@JesseOsby]

Wow, great video - I tried doing a panel like this without knowing any of these tricks and it turned out terrible. Now I'm excited to try again

[@bmerigan]

Makes me want a router (and a huge workshop). Pro-level skills. Much harder with my jigsaw.

[@JeffBrandt242]

You have the coolest "toys". Nice work. So clean.

[@quinlanhart2646]

How often do your projects/installs go over time and over budget, and by how much?

[@obeytre588]

I’d like to see a video on how you guys keep them in place/bolt them in, like a detailed video i gets its boring but it’s necessary

[@evantaur]

if you have dremel discs lying around you can use those for drawing profile

[@avielnachmias2795]

Can you post a complete ''package'' of speakers and everything that you this that is good but not cost to much ? i dont really know about gear so i need your help ":)

[@rideordiesquad7700]

I have a question what is it possible to make a speaker adapter so I can change my 5.25 to a 6.5 speaker on a 2022mazda cx5

[@rayproductionsbackupchanne3862]

How about cooling the amplifiers? They seem to be buried away from any ventilation it seems. Wouldn't that hurt amplifiers in longer durations?

[@randellrivers9256]

Can you design a custom speaker box for a 2004 Nissan Maxima and post it up that would be greatly appreciated

[@SDott-yc2fd]

Q & A ! 2007 Ls460 got a pair of subs that i love but the box doesn’t really fit can i cut notches out of the bottom to make it fit and if soo will it effect the sounds?

[@obeytre588]

So does everything just fit into place or do you Bolt/lock everything into place with some screws or something cause from what I see they just sit in place

[@klubstompers]

Why didn't you just use the "adjustable curve" to get the side contour of the trunk? Another thing that works very well, is to use a metal hanger, or equivalent to form the shape. It bends to the contour and keeps the shape till you transfer to cardboard or mdf.

[@kitler24]

So he can market another new product of course

[@bmerigan]

I would have thought it's too flexible to pick up and maintain a shape

[@christopherrines3012]

I tried to do this in my trunk and it's a pain in the ass to keep it along the lines. At least the one I have does not stay in form easily.

[@charliedee9276]

The rings are much easier. They are nothing new, we used them way back in the manual drafting days to make parallel lines using a triangle or sweep as a guide. The were called "ring gauges" and came in different thicknesses.

[@seancmadison]

Do you have a link to the rubber circles you used instead of washers for the outline of the trunk?

[@mikereiber9049]

What kind of car was this done in. I have a 2013 Charger Rt that im at rhis point in. My trunk has a weird hump on either side.

[@0852ademir]

[@VanDamArtisan]

How does the false floor change the sound quality? Is that a potential issue or does it not really matter with subwoofers?

[@markwentz8332]

It might get covered in a future video but is that beauty panel not going to restrict or muffle the sound from the subs? also, will airflow around the amplifiers for cooling not be an issue?

[@CarAudioFabrication]

The beauty panel will have "holes" that are shaped to look cool for the subwoofers and for the amps. There is plenty of room for airflow around these amps, they are designed well so they stay nice and cool anyhow. I did a video in the past testing the difference between having a beauty panel and not, watch it here: kzbin.info/www/bejne/qnqUgoCAmc2dq7c

[@markwentz8332]

In hindsight i figured you'd have a plan, don't really know why i asked the question.

[@j1mbobtech]

OK, I don't get it... All this talk about how the box has to just so... And then you make a box, not sealed or volume measured in any way, and just how is the sound not to be muffled (covered in MDF)... This actually defies everything you have been saying...

[@CarAudioFabrication]

This is just one video in a series. You need to watch the full series. In the enclosure construction video I definitely calculated the internal volume of the stacked enclosure, and in videos after this one I create a custom mesh grill that sits above the subs

[@SomeRandomPerson163]

I difenitely see what is your favorite power tool xD

[@charleshoppe913]

what thickness mdf do you use for flooring and panels

[@mossemies]

Holy mother of f...word here. Where the f..ck you get all of your gizmos and stuff? I mean for example that adjustable curve??? Where the heck did you find that kind of think? I have installed and fabricate all kinds of stereosystems in cars now about 23 years and i have never even heard about such a thing. I have always made my trim panels or beautypanels with cardboard templates and jigsaw, belt sander, angle grinder. I need those tools too :O

[@CarAudioFabrication]

You are doing things the hard way, check out my show sponsor Mobile Solutions. www.mobilesolutions-usa.com

[@AssadNiang]

wow, very impressed with the quality of work!!! I will let you work on my car anytime.

[@lucaspatrizi3919]

Guys, i'm new in this segment and i want to put some subwoofers on my car should i go with 2x Kenwood KFC-XW12 or 2x MTX RT12-04 and what module should power these subs? I'm not from the US and the local brands here suck, people recommend a lot these two models

[@nebulousJames12345]

let me ask you....why build the box for the sub and not just mount them on the top piece? Is there a problem with using the metal of the car's spare tire frame as the box? Perhaps sound deadened?

[@CarAudioFabrication]

It would be difficult to seal and the thin sheet metal would resonate. Better to have strong dense MDF

[@cheyofromdw4502]

Mark where did you go to school for audio? Or did u just become a beast by yourself.

[@fxgamer-11yt]

He is self thought if you go to his videos there a video where he talks about being up all night and days studying to teach himself more

[@Deke1]

you mean Self "Taught", not thought

[@Lilooh]

thank you so much

[@codywalton5020]

I got 2 skar zvx15s that are 1500 watt rms each and a 8000.1 taramp amp would a xs d3400 battery and 250 amp alternator be enough power for my set up or what would u recommend

[@mallred4347]

Hi Mark, Do you still take on customer installs? If yes, how doI contact you for discussion of what you would recommend and pricing. Thanks, Mike

[@troy5140]

Help Mark! I bought four 8 inch subs (2 ohm dual voice coil, nvx) and an audiocontrol 1200.1 epicenter. I thought it would be enough power but it turns out the rms of 250 each sub was for a ported box and mine will be sealed. Now I need 400 each sub. I know I lucked out because the audiocontrol amp can be linked to an additional amp but I have never done this before. Can you please suggest which audiocontrol amp you reccomend for me to add and how exactly does it work? (How does it combine the power of two amps and spread the power evenly to four subs?) Thank you Mark

[@ELRORRITO1]

Hey Mark. I want to the the same with my Pathfinder how much room is needed from the subs to the board. . I will be doing a sealed enclosure with 2 Infinity Perfect 12s underneath. With me adding the false floor affect sound and performance?? PLEASE ANSWER HERE. I DO NOT HAVE INSTAGRAM. Thx

[@julianjennings4638]

Hi Mark. Long time! Thanks for your channel. It's been great to watch you grow! Build yourself a table saw sled, and practice using it. When you're used to it, it will save you time. If you tape stoppers to it, it makes repitition a breeze. But it takes practice! Go well. Thanks again.

[@jcoats5529]

How are you going to keep that cover from flexing or bouncing and basically vibrating?

[@mike7370]

Why to use the router bit with square bearing and not round bearing on the plastic curved edge guide?

[@CarAudioFabrication]

If you don't use the square bearing the round bearing will damage the flexible curve

[@mike7370]

CarAudioFabrication thank you!

[@spbygga8123]

I was going to ask the same question. Thanks

[@rasmushassing4649]

Q&A question! I have a 2010 smart for2, in which I have installed a pair of rockford fossgate speakers in the front doors. In the speaker set there is a square block thing, that I want to be shown in the door, but the place that I want to put it, is upholstered from factory. My question is: how do I make it look like it’s installed from factory? I will send a photo on Instagram so you can see what my problem is. Thank you for your amazing show, and please keep on the awesome work! Cheers, Rasmus from Copenhagen

[@ericlewis5035]

Awesome video. This helps me A Lot. I want to make a False floor to carbon fiber it. I like the WASHER idea. Thanks for sharing

[@anestiskariotis2728]

Can you share the type of template tape you use?

[@fauxho6163]

JL Audio HD 600/4 or an old school Soundstream Reference 604 for Focal ES 165KX3? As well, DSP (8 ch.) of choice for this application?

[@NikiKnuckles]

Hi. Thanks for all your time making this video. Why do you use cyanoacrylate? For the buzz, fast time? Tell me why nothing else please. Have you tried alternatives?

[@MrJaime818]

What thickness of wood did you use?

[@fitimshaqiri]

Can a smal box damage a subwoofer

[@charliedee9276]

How does the bass sound with a cover over the speakers? I ask for two reasons. Not real up on mobile audio, I know enough to be dangerous. And I want to mount a stealth sub in my Jeep Grand Cherokee and the spare tire well is a perfect place, the large tires I run are too big for a spare to fit in it anyway. I would have to have a rigid cover though as I use it to haul my tools as a carpenter, the sound comes through good enough? Great channel, I have learned a lot.

[@albinmoller426]

Hey Mark I’m about to do a build for either 2x10s or 2x12s. But it’s a tight fit for a normal box with tilted front so I’m gonna have to do a custom box cuz in the middle of the box I’m gonna have a half circle cuz of the gear box cut out so my question is should I stack some MDF and cut a half circle or just make it square?

[@OneNTwentyOneMillion]

You and Doug should have a "build-off". Using all the same components. The viewers will vote for creativity and looks. For sound you and Doug will have to hash that out.

[@leviisrael3752]

do you have employees?if not are you planning to expand ? if so what would be the application process to be part of your team?

[@brandonthornell9663]

With a complete false floor like this with several amplifiers and very good sound insutation, do you need to worry about the heat generation from all the electrical components?

[@Mixer_Driving_Nurse]

Just about ready to build an enclosure for my S10 and need a way to mount my amp that will not be intrusive to the rest of the cabin, but yet still be visible and accessible due to the enclosure needing to be very large. I’ve read a lot about not mounting the amp directly to the enclosure due to vibrations, but I was wondering if I could add a secondary layer to the the front wall if that would be enough to cut the vibrations down?

[@littlebullcastro5931]

If you do a down firing sub, how much space should you have for clearance? And will it hurt the sub to not have enough? My sub has enough where it won’t hit but I didn’t know if it needed a set amount of clearance for the bass

[@ADR69]

Can you explain how crossover roll offs should meet each other when? I read that , for example, a -6db crossover slope shouldn't meet with another -6db or something like that due to cancellations. That's always been hazy to me.

[@KayKashi]

My floor in my trunk is bare of cheep pressboard and it’s bowed. I just need a replacement floor in general, don’t care if it’s pretty or even has carpet on it

[@stevenlong4567]

Great content. Have you ever fiberglassed the spare tire well to save weight??? Thoughts???

[@jcwindevillose]

I love your channel. Mad skills. I’ve never seen u add cooling fans. Any reason why? Plan on redoing my car stereo and that’s a big issue with what I have.

[@terrencebrill5489]

Can you do a tweeter pod build for a sail panel? It's one of the few things I've never seen you cover, yet to me it's one of the most common builds a DIY person will need. You have certainly covered the basics in all of your videos, but I would like to see how you handle aiming the tweeter, temporarily securing it, and setting it up for vinyl. Then I 'd like to see how you fiberglass a small sail panel without interfering with the door or window and also how to apply vinyl to it. I've done sail panel builds twice and I've struggled both times! Almost seems not worth it to be honest. I'm hoping you can shed some light on this. Thank you!

[@firstphoton655]

[@thememeyata6837]

Would this cause loss in output

i have sony xm-n1004 amp how many subwoofers can i conncet and how pla help sir?

[@jonathantenorio8829]

This is car audio fabrication art! I love it. Really got me some more ideas to do my build

[@oldsilkhat7893]

What brand of router table and bits do you use? They seem stout and cut like butta.

[@morgen2289]

why were you routering the underside of the panel then flush cutting afterwards from the other side? also whats up with the square bearing on the router bit? nice work as well much respect

[@MrVuittonDon]

I need to find a guy like this in New York City. Very clean setup.

[@kevinali1642]

How come you didn't use a plastic material for the cover instead of mdf?

[@hugoortiz05]

If you had an old vehicle with a missing spare tire cover what would you use in its place. Or to make a new one

[@iMakeItHappen96]

Whats a round over?

[@pepelepew158]

What kind of car is this.??

[@alphalanos2]

looks like a pontiac grand prix

[@Harvey600]

I’ve been watching your videos for quite a while now and I’m planning an afternoon install for my van. Got a couple of questions. What size cable should I use to link a 250wrms sub to the amp, the cable will be 150cm long. Second question, if you have amps or crossovers to one side of the vehicle, do you always keep the cable lengths the same, left side compared to right side? Thanks Jimi Wishbone (instagram)

[@AmbaSnakeman]

For your speaker selection, if they are designed for high res audio, do you use matching high res amps?

[@mauriceward2090]

Thank you for this video bro.... does anyone else think he sounds like an adult Kermit?

[@hotpudding9741]

I just trace the original mat on to the board I'm cutting and it fits perfectly.

[@unforgiven101inc]

what do you do about the heat the amp's build up produce...

[@CarAudioFabrication]

Use quality amps that aren't based off 1980 designs.

[@vinnygalanti9221]

Mark I can never find the links down below in the comments

[@jaz97]

Way beyond my wood working skills, and tool access. I do want to build a spare tire enclosure.... 1 day. Nice work tho

[@ericchavez6053]

awesome work, looking to starting my trunk layout and making a subbox with pexi opening. (but no idea where to start) also wanted to know do you have a video of how to mount the false floors and beauty panels to the actual car itself?

[@shubhamjoshi2064]

Why not subwoofer efficiency more than 4-5% ?

[@andychp]

This is amazing - how much does this sort of set up cost and where can I look to get this done in the uk?

[@wicked89joker]

Do you fiberglass? Or and if so would you ever do a step by step video on fiberglassing

[@eacalways]

Darn I thought about doing this on my trunk but I don’t own tools like you have😏

[@rodamik]

No concerns about ventilation for the amps to breath so they dont overheat...or is there more to come???

[@denverwatkins6844]

Rodney Mikell use small 12v dc computer fans

[@slow_rednline4874]

There is plenty of airspace.. have you ever heard of a sealed box?

[@jethro9341]

Why cant you just push the adjustable curve up to the sides and use that as a template?

[@hywmfg]

What routers do you use? Also where did you get your adjustable router plates?

[@dougthomson333]

Nice work

[@lampinlance]

Once again, nice video Mark. Now for questions. 1. For a SQ install and to block road noise, would you recommend SoundSkins Pro only, Sounkskins + MLV, or install CLD, CCF, and MLV the whole vehicle? 2. Does it hurt the mid-bass performance to put a type of acoustic insulation inside the door? I see your approach to treating the inside of doors like a box with only a fast ring or similar to help the back wave. I see other guys install acoustic insulation in doors. What's the best approach? 3. Is there a clear winner to what is the very best plastic to use for speaker adapters? (HDPE, ABS, acrylic, etc) 4. When choosing power wire, oxygen free copper is a must. But how do you handle corrosion and oxidation? Is tinned OFC better in the long run? 5. When choosing ground terminals, what do you recommend to be the best material to use? 6. When building sealed subwoofer boxes, I see boxes ranging from no fiber fill up to filling a large portion of it. I can see a side or two having a layer applied, but what is best? 7. How mad will my wife be if she found out how much I spent on stereo gear? :) 8. What do you do for a living? Just curious. 9. Is it ok to use a non-spiral flush trim bit on HDPE? Or do I need a spiral bit?

[@lampinlance]

One more question Mark, can you record and post the instagram video on youtube please? Thanks

[@NTRCOOL]

How much will the floor panel affect the amplifiers as far as their heat output?

[@mattlawrence5852]

My car has a factory amp which apparently has an active crossover built in. My question is, can I used the audio control DM810 to change the signal coming out of my factory amp (example: front doors have a mid-bass signal only) or would it just enhance the signal I have?

[@frankthetankricard]

That processor has signal summing and a 30 band equalizer so technically it's possible to stitch back together the source signal even after it goes through the crossovers. If it's an option, I'd rather recommend capturing the signals coming out of your head unit and circumventing the stock amplifier.

[@BIGTAGGART]

What is a good way of securing the false floor to the car

[@iMakeItHappen96]

How did you make the fuse access specifically?

[@georgerudinsky489]

Good job

[@575burntoast]

Do you think you will ever do a subwoofer wall build tutorial

[@tk146boy]

I've seen several videos about bypassing a car's factory amp, but nothing about adding onto it. I have a 17 elantra with infiniti's Clarifi sound processing. The mids and highs sound great, but the lows from the factory 8 inch sub are lacking. I wandered if it would be possible to install a second amp and larger sub in conjunction with the factory system.

[@DustinPrat]

tk146boy it would be relatively simple, you would need your added sub and amp and to get your audio signal you would need a line Lever convertor that takes high level input from an existing speaker (splice into the wires) and then you could send the signal from the convertor to the rcas on the after-market amp

[@oscarlover131]

soundman/ Fab kitchen colab anytime soon?

[@DJMoPhiya]

Soundman takes too long.

[@gronlond]

Perfection isn't formed overnight

[@akashah2001]

My country doesnt have professional audio fabrication like you or maybe smd??.. The point is what do I to need to do? I have a soundstream 10" subs but dont know what to do?

[@frankthetankricard]

If you don't want to do it yourself, you can always order a custom box design from Mark and have any decent woodworking shop assemble it for you. Put your amp under a seat or integrate it on the sub box and it's gonna look clean.

[@genuineknowledge9336]

Video is amazing & restful to watch. Clean job. Impossible to do it myself though for my old car.

[@CarAudioFabrication]

You can do it!

[@edwardgarza5104]

Hi, which shallow mount subwoofes do you see the most being installed in crew cab trucks? Thanks

[@alexmorrison5327]

Fab it like it's hot. You is crazy good bud I need to do something like this on a miata there isn't alot of room.

[@TheJedidragon529]

I'm thinking about doing something similar in my car but I am worried about the sub sound being diminished by the false floor. Is there anything you would suggest to ensure the most/best sound still reaches the interior of the vehicle and doesn't get hidden behind the false floor. Thanks.

[@CarAudioFabrication]

Watch the rest of my build to see how I account for this.

[@filipecunha4931]

Great work, it is always difficult to hid a sob box, you make it seems so easy. Believe you will have an opening in the middle for the sound coming the subs or will you place some vents over the sides? Mark, could you do a video where, you discuss the best approach for improving the subs on sedan like a Mercedes or a BMW where the back of the rear seats and rear deck are in steal.

[@DanielWilliams-g3t]

That’s awesome man 👌🏻👌🏻👌🏻🤞🏻

[@MikeTatman]

How will you deal with the heat from all the amps when they are covered up like that? I discovered your channel while searching through wood working videos on KZbin. I love car Audio also. I love the channel thanks for all the great info.

[@CarAudioFabrication]

Check out the video I just released on my channel. kzbin.info/www/bejne/iqu3mZaqrrF0g6c
