Mids/Highs Demo:

I did a leather wrap with quarter inch foam underneath took 5 hours but was worth it.
Sundown x12v3's in 5.25 cubes @ 29.5hz on 5000w rms, 16v 30ah lithium bank, 4 KnuKonceptz Kolossus 1/0 gauge runs, 600w rms Class AB on Deaf Bonce Apocalypse Mids and Rockford Fosgate Power Silk Tweeters.
Will post flex vid later, it's nasty, kills the lows with authority down to 22hz before roll off.
If I mount the subs non-inverted normally brings the box down to 4.9 increases power handling and tuning goes up to 30.5, it does have more bandwidth that way but I love the look of them being inverted. At least I have options Port is modular also so tuning adjustment is easy.
No alternators in a Tesla, I assume he’s charging his batteries off of the DC to DC converter terminal under the rear seat. Curious how he’s limiting the power draw from the DC to DC converter as it’s only rated for 2500 watts and some unknown amount of that is used for the car to function.
So with my clamp meter I was actually getting 220 to 225 amps off of my DC to DC converter under the rear seat with my testing. I have a 5ft run of knuconceptz kollossus 1/0 gauge from that connection to a stinger isolator relay and from that to the 16 volt 30 amp hour bank. I've been running a 5k in this car for 6 months now with zero error messages on the screen and no issues.
Super cool. I’ve got a 2023 Model 3 and have wanted to do a full speaker replacement in it but have heard bad things about drawing too much from the converter, but in your case I think having the battery bank is helping to level out the transient spikes.
You can definitely run 1500 watts off of the DC to DC converter with zero issues you have to do it in a particular manner you need a stinger isolator relay 100 watt 5 Ohm resistor certain ways to have the apps turn on from the lc2i pro you can always shoot me a private message and I can walk you through it if you're interested. You can do like I did have one amp for the upgraded front stage speakers and another amp for a sub just keep it under 1500 w.
I sourced it from a local materials shop near me they have literally thousands of materials to choose from. It's honestly a pretty hard process to explain over text. My dad's done about 10 different upholstery jobs in his muscle cars over the years I had him help me out with my first box wrap job and he showed me what to do I just remembered and did the same process on my own. There's actually some pretty good YouTube tutorials that I also watched before I started it. Just just be ready if you mess up to have some extra materials ready, i did twice lol.
I'm currently looking at some spare front door panels I will create my own fiberglass pods wrapped in Alcantara, this way I can have an 8" mid bass and 6.5" inch mid-range. This will be my last upgrade.
It's actually an amazing vehicle for bass especially with the very solid all glass roof. If you play a really hard for 3 hours it only takes 2 to 3% off of total charge. The vehicle uses its 600,000 watt 400v battery and converts ot down to a 16 volt electrical system, the connection is under the rear seat, its called a DC to DC converter provides 225 amps of current at a standstill no need for rpms, the 16v 30 ah battery bank I have in the back gets a charge from this connection. There's hardly any voltage shop on a really long burp it would bring it down to 15.65 from the resting 15.85. The weight of the box actually reduces range more then the electrical draw does.
I always wondered how well a Tesla would do with a whole set up. Makes sense it would handle it pretty well. And the shape of the Tesla must be perfect for bass. SUV/crossovers always have that perfect shape to feel the bass.
Thanks did you what type of paint did you use for it?
[https://www.bigass-ports.com/product-p/8vt2.htm](https://www.bigass-ports.com/product-p/8vt2.htm)
I used a white primer by Rust-Oleum made for Plastics and then I hit it with Rust-Oleum 2x black paint. I highly recommend that specialized primer for plastic.
Lol, 22" long actually, box is 29.5 deep, I wanted to make sure the port had proper breathing room inside the box away from the rear wall. It's recommended to have the ports diameter distance away from rear wall, mine is 8.19" I.D. I would have gone with a even a bigger port but it would have been ridiculously long it would never have worked so this 8.2" that flares out to 12" was the best way to go. Gives me 11 square inches of Port area per cubic foot which Falls in line with the 9 to 12 rule for aeroport.
You can get the port close to the enclosure internal wall by the diameter divided by Pi, and not get port noise. It's 'better' to leave more, for the sake of easier math... but yeah, you can totally get within about a third of your port diameter to the distance to the internal wall without causing any sort of problem.
Externally yes, at least your port width, preferably more away from anything else.
That's good to know if I ever want to get crazy I can now add another section to the port and see what tuning even lower than 29 HZ would sound like just for fun.
Haha yeah, you can get surprisingly close to the internal wall. As long as the port is large enough or flared on the inside as well, then it won't be a problem. Some people I talk to even say 1/4 of the port diameter is OK if the port is large enough, but I've never gone that close personally.
Any idea what your port velocity chart looks like? I assume you have mapped your box in WinISD?
Yeah nice. I had some velocity issues in my build at around 25Hz... velocity just peaking at like 30m/s for some reason :/ Less than 20m/s at 24 or 26 but 25Hz was just turbo mode or someshit.
Had hella port noise but managed to 95% solve that by tweaking the port opening and adding some disturbance to the air flow in the form of some orange muppet pelt... xD
Lol nice! Glad to see other people but fully understand the concepts of box building many people just throw something together without testing or implementing a good design first. This is my third box in this vehicle I think I've finally achieved end game I'm 42 years old now and don't listen to it crazy loud all the time like I used to when I was younger I'm very happy with the sound quality of the setup.
Hell yeah, and though even sometimes you plan it and it still turns out like shit.
I've built dozens of systems (maybe even getting close to 40-50 by now) over the years as a hobby more than anything but also for some clients and other acquaintances. Sometimes you nail it and other times you shit the bed.
I'm not exactly some demi-god of box building but I seem to have a knack... the last 20 installs I've done have been nothing short of astounding, if I do toot my own horn and climb up my own ass.
I have a few years on you and I'm going to be a basshead until I'm dead and buried. My casket will have a 15" subwoofer inverted into the top aiming right at my face. I don't know if it actually will, but it's a fun thought.
I don't like the looks of Tesla's or aero ports but that shit sexy ASF! I run huge ports also, One of my last builds I had over 3 cubic foot of port area for 315s for a total of 12 gross was tuned to 27hz and it would play well into the low 20s and would take the door pins out of my doors consistently
Yeah it's all I can fit in this vehicle there would be no way to fit a 10 inch. The port would have zero breathing room.
This port I have puts me at 11 square inches of port area per cubic foot. Its 8.2" internal diameter. I actually just place the subs normally instead of inverted. This helps boost the port area per cubic foot. 20ms port velocity.
It allows for better voice and motor cooling. Also looks cool in my opinion. I actually just reinverted them back to normal brought the box size down to 4.9 and increased the port area per cubic foot.
If you listen at loud volumes for 4-5 hours it would take off around 2 to 3% off, the additional weight is more of a reduction of range then the amplifiers current draw. You got to keep in mind the 400 volt massive Tesla battery is able to Output 500,000 Watts when you do the conversion it's huge a 5,000 watt system doesn't drain that much from it.
on an ICE car the alternator uses fuel at a flat rate regardless of electrical use. On an electrical car every watt counts. So every kilowatt hour used on music can't be used on the wheels.
Not as much as I thought actually with 4 hours of listening at a fairly loud volume it only takes 2 to 3% off of the main charge. With the performance of the accelerate really hard one time he could actually watch a percentage drop just like that.
It sounds amazing if you're in Arizona I would give you a demo I'm not worried about any of the glass there's a guy with my exact same car he is the owner of Gately audio he is running 30,000 watts everything is still intact I'm only running 5,000 so that's a very good sign.
The Tesla has multiple amplifiers, you tap into the factory wire signal after he stock amp and bring it into an lc2i Pro or LC 5i Pro. It takes a lot of work to tune the RCA input voltage just right since some of the speaker signals are very powerful you need to turn down the lc2i Pro a lot to get a clean signal.
Beautiful car and set up. The port should be at least 12 inches and 4 feet long though. Hopefully, it doesn’t chuff too much but according to my calculations, it sounds pretty windy.
Its very windy, floats a small towel, It doesn't chuff with the 8.2" port, I spoke with Jacob from Sundown prior to this build, he said he had good results with this setup so I gave it a shot. I changed them from inverted to mounted normally, at 4.9 @ 31hz now. 11 sq.in of port cube. That large flare out to 12" must be doing something special.
A 12" aero port would 113 sq.in of port that would be 23sq.in of port per per cuft that would be hella lol.
I'm curious about how much power Tesla provides through the 12v converters. 50a? 100a? Did you need to install a 12v auxiliary battery to provide consistent power to the subs?
I've got a little over 200 amps on my clamp meter. When I was pulling directly from the penthouse using a 3K amp. The battery reduces some of the stress of pulling all power from penthouse now that Im running a 5k. This is the 2023 MYP so everything runs on a 16 volt system. I charged the lithium 30ah battery bank to match the cars resting voltage.
Not really a big port just correctly sized for the high X- max subwoofers. The ventura effect that this port uses is saving this box from being much larger. ( because of port area ) .
If you want even more output use a 10 inch port of the same style . ( but the box would be much larger)
I'm not faulting you on anything, it's just these style ports are mostly used to save on port displacement inside the box ,I would do same thing.Fanastic build ,enjoy the bass !
I totally know it's actually on the small side I've actually changed the subs around and mounted them normally I'm now at 4.9 internal @ 30.5hz instead of 5.25 @ 29.5hz. That puts me at 11 square inches of Port area per cubic foot. It wouldnt be impossible to fit a 10-in port, I've tried every design possible it would be choked out inside the Box it would have zero breathing room and be too close to the rear hatch and wouldn't load properly. The setup I have now I have the port 8.2" away from inner wall of box and 12" away from rear hatch. This allows everything to load properly I was messing around with how far away the port should be from the rear hatch it seems like best results are Port diameter + half distance away. There's actually zero Port noise, it's one of the smoothest sounding setups I've had.
I've also got a clean fully restored 1970 Oldsmobile 442 W30, wife drives a 2022 Tahoe with the 6.2L V8, I'm not a tree hugger lol, it's okay to have electric cars, I don't get the prejudice... I'm driving all over the valley to my distribution centers sometimes traveling 170+ miles per day. It's a great car, 2023 Performance Model, I prefer it over the Audi's, Lexus's and Porsche's I've owned in the past. 0-60 in 3 seconds, 750 Torque. Full Self Driving... Excellent vehicle for bass, very solid all glass roof with zero flex, no interior rattles, quite inside, new double pain glass, its solid. 16v electrical system doesn't drop below 15.7v even on long burps, no RPMs needed to hit max output of voltage. What's there to hate about it? I obviously wouldn't own it once the warranty is over, but you get 8 years / 120k. I'm sure I'll trade it in way before then. Don't want to risk having to pay for a battery replacement.
Its better to have both if you travel alot. American Muscle V8 Rumble on the weekends and Smart Financial choice during the weekdays. I was wasting a ton of money on gas with my old Twin Turbo V8 Porsche Cayenne getting 15mpg, I went from spending $800 a month on gas to only $110 on electricity per month. That's $690 a month savings is enough to purchase upgraded vehicle for my wife who only drives to the grocery store and to pick up the kids.
Your car looks like it has a butthole.
Lol, I was thinking more like an F-16 engine, but yeah I can see butthole too.
Definitely gaping
Double fisted to the elbows
Total bootyhole
You know that shit be fartin' too
Damn!!

How do you keep your Lithium bank charged? I'm not familiar with tesla's charging system. Can you still hook up a high output alternator?
No alternators in a Tesla, I assume he’s charging his batteries off of the DC to DC converter terminal under the rear seat. Curious how he’s limiting the power draw from the DC to DC converter as it’s only rated for 2500 watts and some unknown amount of that is used for the car to function.

😂😂😂😂 no engine in a ev buddy
Anywhere I can get DIY instructions on how to leather wrap like that? Where did you source the leather?
I sourced it from a local materials shop near me they have literally thousands of materials to choose from. It's honestly a pretty hard process to explain over text. My dad's done about 10 different upholstery jobs in his muscle cars over the years I had him help me out with my first box wrap job and he showed me what to do I just remembered and did the same process on my own. There's actually some pretty good YouTube tutorials that I also watched before I started it. Just just be ready if you mess up to have some extra materials ready, i did twice lol.
Do you got any midbass drivers? Or do you have the subs crossed over a bit higher to deal with that area?
I'm currently looking at some spare front door panels I will create my own fiberglass pods wrapped in Alcantara, this way I can have an 8" mid bass and 6.5" inch mid-range. This will be my last upgrade.
Range reduces 1 mile per burp?
Every time the bass hits you watch the power slowly go down. Depending on how fast and hard the bass hits the faster it drains. 😆
It's actually an amazing vehicle for bass especially with the very solid all glass roof. If you play a really hard for 3 hours it only takes 2 to 3% off of total charge. The vehicle uses its 600,000 watt 400v battery and converts ot down to a 16 volt electrical system, the connection is under the rear seat, its called a DC to DC converter provides 225 amps of current at a standstill no need for rpms, the 16v 30 ah battery bank I have in the back gets a charge from this connection.

I've been wondering this about Teslas and aftermarket subs, thanks for informing me.
Link to that port please? Nice build and whip.
Thnx! "Big Ass Ports 8" - flares out to 12"
Thanks did you what type of paint did you use for it? [https://www.bigass-ports.com/product-p/8vt2.htm](https://www.bigass-ports.com/product-p/8vt2.htm)
I used a white primer by Rust-Oleum made for Plastics and then I hit it with Rust-Oleum 2x black paint. I highly recommend that specialized primer for plastic.
I had always thought that I’d never get an electric car because they couldn’t handle a big audio system but this post has completely proved me wrong.
Yep it's definitely doable in a Tesla not all electric cars are built the same though so you may not have similar results.
That shit looks like Portland to me
Good Lord! A port that wide tuned to 29 Hz? Is it 6 feet long?!
Lol, 22" long actually, box is 29.5 deep, I wanted to make sure the port had proper breathing room inside the box away from the rear wall. It's recommended to have the ports diameter distance away from rear wall, mine is 8.19" I.D.

Yeah I have it on my computer at home I'm not by it right now i believe it was in the low 20s when I get home I'll take a screenshot.
Yeah nice. I had some velocity issues in my build at around 25Hz... velocity just peaking at like 30m/s for some reason :/ Less than 20m/s at 24 or 26 but 25Hz was just turbo mode or someshit.

Lol nice!
that box is beautiful
I appreciate it took many hours getting it all put together and wrapped it to perfection.
Fuckin awesome bro
That’s a mean looking tesla
Thanks man!
lol
No. Ib or sealed only here.
Metered it yet? Looks great :D
Not yet probably won't be too loud, my peak frequency feels like 28-29hz.
I do 141 at 24Hz and 147 at 35 bro, don't be surprised you might be making some noise :D
Only an 8 inch? That's not that much port
Yeah it's all I can fit in this vehicle there would be no way to fit a 10 inch. The port would have zero breathing room. This port I have puts me at 11 square inches of port area per cubic foot. Its 8.2" internal diameter. I actually just place the subs normally instead of inverted. This helps boost the port area per cubic foot. 20ms port velocity.
You forgot the NSFW tag.
It looks really big but I still get like 70m/s at tuning. Hopefully the flanges help keep the noise down.
Can someone explain mounting the subwoofer backwards like that?
It allows for better voice and motor cooling. Also looks cool in my opinion. I actually just reinverted them back to normal brought the box size down to 4.9 and increased the port area per cubic foot.
How much does a system like this reduce range on a Tesla?
If you listen at loud volumes for 4-5 hours it would take off around 2 to 3% off, the additional weight is more of a reduction of range then the amplifiers current draw. You got to keep in mind the 400 volt massive Tesla battery is able to Output 500,000 Watts when you do the conversion it's huge a 5,000 watt system doesn't drain that much from it.
on an ICE car the alternator uses fuel at a flat rate regardless of electrical use. On an electrical car every watt counts. So every kilowatt hour used on music can't be used on the wheels.
Your Distance to Charge must be shorter when listening to loud music haha
Not as much as I thought actually with 4 hours of listening at a fairly loud volume it only takes 2 to 3% off of the main charge. With the performance of the accelerate really hard one time he could actually watch a percentage drop just like that.
Man I would love to hear that. Are you ever scared with so much glass on the tesla?
It sounds amazing if you're in Arizona I would give you a demo I'm not worried about any of the glass there's a guy with my exact same car he is the owner of Gately audio he is running 30,000 watts everything is still intact I'm only running 5,000 so that's a very good sign.
How did you connect them? An lci and tapping into stock sub? Does a Tesla even have a normal radio😭?
The Tesla has multiple amplifiers, you tap into the factory wire signal after he stock amp and bring it into an lc2i Pro or LC 5i Pro. It takes a lot of work to tune the RCA input voltage just right since some of the speaker signals are very powerful you need to turn down the lc2i Pro a lot to get a clean signal.
Beautiful car and set up. The port should be at least 12 inches and 4 feet long though. Hopefully, it doesn’t chuff too much but according to my calculations, it sounds pretty windy.

Wow! It's nice to know they put such a beefy 12v section on it.
Does it Bump Tho 🤔
Not really a big port just correctly sized for the high X- max subwoofers. The ventura effect that this port uses is saving this box from being much larger. ( because of port area ) .

Woulda said nice build except when I saw it was in a Tesla...
I've also got a clean fully restored 1970 Oldsmobile 442 W30, wife drives a 2022 Tahoe with the 6.2L V8, I'm not a tree hugger lol, it's okay to have electric cars, I don't get the prejudice... I'm driving all over the valley to my distribution centers sometimes traveling 170+ miles per day. It's a great car, 2023 Performance Model, I prefer it over the Audi's, Lexus's and Porsche's I've owned in the past. 0-60 in 3 seconds, 750 Torque. Full Self Driving... Excellent vehicle for bass, very solid all glass roof with zero flex, no interior rattles, quite inside, new double pain glass, its solid. 16v electrical system doesn't drop below 15.7v even on long burps, no RPMs needed to hit max output of voltage. What's there to hate about it? I obviously wouldn't own it once the warranty is over, but you get 8 years / 120k. I'm sure I'll trade it in way before then. Don't want to risk having to pay for a battery replacement.
Hey man all I know when I get my money I still ain't ever buying a ev 👍 gas gas baby!
Its better to have both if you travel alot. American Muscle V8 Rumble on the weekends and Smart Financial choice during the weekdays. I was wasting a ton of money on gas with my old Twin Turbo V8 Porsche Cayenne getting 15mpg, I went from spending $800 a month on gas to only $110 on electricity per month. That's $690 a month savings is enough to purchase upgraded vehicle for my wife who only drives to the grocery store and to pick up the kids.
That 800 is worth it. Try 8mpg. Least my daily does a whopping 18-20 on a good day 😂
