[@myevilbanana]

Great video Mark, never heard anyone bring up round port bracing before. Good stuff. Anyone wanting to take their build skills to the next level but don't have the cash to get a router and router table? You can do all the cuts shown with a straight bit, round over bit, a cheap palm router, a home made router circle jig (you can find plans online), a wood clamp & a couple screws. Draw out lines for holes and radii. Clamp scrap board behind cut area to prevent blowout. Set up circle jig for the o.d. of the tube use straight bit cut to depth. Reset jig for i.d. of tube and counter sink 2 screws through the center piece your about to cut out into the scrap wood behind it. Cut out center with router ( this may take several passes lowering the bit slowly each pass). For the port brace cut the circle first then the radius so you'll have better options for securing your work piece. Follow up with round over bit. Start with less then $50 in harbor freight tools, upgrade to better when you can.

Hello Mark. I'm going fulltime with speaker system production at home. Just bought a router the other day & I needed the rabbit bit information/recommendation. I have picked up some vital tips from watching your channel over the years. Thank you!

[@jrader777]

I always wondered how to properly mount this style of port. Thank you! Your videos and craftsmanship are truly top notch.

[@NTZClaw]

I really appreciate your videos. I am a audio enthusiast, but on occasion a friend of two have asked me to build them a box. I usually Vinted style ports boxes or sealed rarely. Your videos are validated a lot of the techniques I use. It has also enlightening on many new ones. Thank you for your contribution to Car Audio and the KZbin Community!😊🙏🇺🇸

[@cmar4076]

Tip: gang up two pieces of mdf with your templating tape and then jigsaw/route out your inner diameter holes at the same time. Saves you some time/steps, plus ensures that both your outside panel and inside brace have their holes perfectly aligned so there’s no stress on the glue joints. 👍🏻

[@shaunscott81]

You are awesome sir. I have always loved car audio, but the shops around me act like I don't know anything. The fraction of knowledge I have and your assistance I quit going to them and started using your recommendations. I will build an extremely awesome system for my 1972 chevy caprice restoration.

[@davidtravers410]

I have always enjoyed all of your videos, I have learned so much. Your knowledge, attention to details and how clear your explanations are, makes learning so easy. You never come off as arrogant and have a great sense of humor. I completely agree with Rodman8500, you are the “GOAT”!

[@keanuventer4239]

Hey Mark ,could you make a video on how we determine what the "right" tuning frequency is for a custom sub woofer install ?

[@Chuck_Sanders]

Grab a DATS program from Parts Express. Run the DATS program on your subwoofer, to get the TS Paramters. Use the TS Specs, to determine your proper tuning frequency for your specific application.

[@movie_av_impulse]

@@CarAudioFabrication hey I had a quick question for you. I'm running a single 12" infinity kappa 1200w in a vented ported box. The box isn't big enough for the subwoofer so I'm having my local shop build one to spec. I'm running a SKAR amp at 600 watts at 2ohms. My question is before I give the green light which hits better a TUBED flared port or a vented port box? My local shop said a TUBED flare hits better but I don't know. Thank you I love the channel because of you I bought and running the LC2i in my lexus so I no longer lose out on bass when turned up past 45 thanks again 😊

[@bobcat3653]

​@@movie_av_impulseSo which port did you use - aero port , or slot port ??

[@movie_av_impulse]

@@bobcat3653 that setup is not my setup now I'm running a 12" NVX in a slot ported box with 1,000 watts and 2ohms sounds and hits much better.

[@JacobFrey]

I love round ports! Great design, Mark. Would you go as far as wrapping the PVC in some sound deadening material to add mass? Just curious what you think about that - I would have to ponder it if I were building this enclosure.

I had bought 3 12's a few amps and head units from a buddy. Got it home and realized I had no idea what to do with it. Found your videos now I'm hooked . When I get this box finished I'm going send you a video. You helped me get it done. Thanks

[@cartruck1070]

I was just thinking, why dont people do this insted,then this vid pops up while im scrolling to show my son the install vids. Nice! 😎👍👍

[@maryirle1983]

How would you go about the carpeting around the port perimeter?

[@CarAudioFabrication]

Go a little deeper with the roundover. It will leave a perfect crisp line to run your blade in to trim.

[@maryirle1983]

That sounds about right. Has anyone ever told you that you are a very smart person? What's your IQ?

[@maryirle1983]

Oh, I had one other question if you have time. Do you have a video on port/vent and cone clearance? Like the distance between the inside wall of your trunk from your port opening. Because I only have about 2 inches clearance from my port to the trunk wall and maybe 3 inches from my sub face to the back of the seat. Am i losing sound/bass quality? I cant seem to find any videos on this. Thanks

[@djkritical9606]

How would you calculate the flare of the port when building it like the video

[@CarAudioFabrication]

Just like usual but account for port end correction.

[@jimmybass7595]

This is awesome. Anyway you can do a video on how to design an aero port. Like all the calculations and building it from scratch and flaring ends? Would really be interested in that. Keep up the awesome work.

[@billyboyd418]

You can use an online calculator and figure out the length from your volume and tuning hz, then follow this video

[@nickparkin8527]

You should get a CNC machine. I’ve been into audio and just got a shapeoko 4 xxl and it allows me to make some pretty complex enclosures. Basically you cut 3/4” material and cut a bunch of “rings” that have the same cross sectional shape of your enclosure. Make a bunch of them than stack them up and glue em together. This allows you to make your walls as thick as you want, and you can design 3 or 4 of the rings to incorporate complex bracing that will keep your enclosure as dead as possible.

[@cjon24s69]

I literally made a box with a pvc port today and had some port turbulance, I will definitely try this

[@HifiVega]

Love the rabbeting to mount the port! Great technique as always Mark.

[@readcomics]

Awesome work and amazing insight to the type of work you do, Kudos my friend

[@larrymontgomery4902]

Bro that looks really nice,i like the way u did the opening for the port

[@kingcosworth2643]

A trick I do is make a wooden ring that you afix to the box wall for the port to slide into. If you make two, and sandwich them together, make the ID slightly bigger than the OD of the pipe on one ring, and match the OD on the other, when you afix the stacked rings to the box wall, a recess is created for the carpet, vinyl or leather to go into as the covering goes into the radiused port. Cover it, and then when you slide the port in, it will clamp the covering and give you perfect edge from covering to port, and will hold the covering and make sure it will not come loose.

[@ap6462]

Killer build and most excellent idea with the port support! Well done!

[@wattz18]

Mark, I've been watching you videos recently and I have a question. First off gotta give a disclaimer, I have been away from car audio for about 15 years. When I was building my stuff for my cars (I was a budget guy) I used capacitors to help with electrical current draw on my electrical system. I see that you've said nothing about capacitors, are they not a thing anymore?

[@christopherblack6607]

I thank you sir for this video it really helped me a lot I am in the process of building a soapbox and this is exactly the style of port I wanted to use and I had a few questions that you perfectly answered!!

[@CarAudioFabrication]

You are very welcome

[@Thomamps]

I've always done this with two pieces of wood as I still don't own circle guides. First is cut to outside diameter as close as possible with jigsaw, second is ruff cut within the inside diameter, glue together, glue onto tube, then use tube to flush cut to inside diameter and then use radius bit too round ends. I always try to design the box so the tube ends at a window brace which is much easier when doing stage and club systems.

[@fishrsa9046]

thats a really neat way to draw the circle, i would never have thought of that

[@mojoneko8303]

Hi thanks for this. I'm building a pair of the CSS Criton 2TDX Tower speakers (not for my car). : ) I like the way you installed the port tube in that sub woofer box and anchored and rounded the entrance and exit. I think I will try this on my speaker build instead of using the port tubes provided. The exit's on the ports I got with the kit have a plastic flange with a 90 degree edge. I think rounding over the 3/4 inch red oak where the tubes exit will look a lot better than the plastic flange. I am lining the inside of the speakers with a 1" thick sound damping material. Is it a good idea to wrap/glue damping material around the outside of the port tube inside the cabinet? Thanks for the video! You gave me a lot of interesting ideas I plan to incorporate into my speaker build. And a bit more work to do.. : )

[@doublemanson]

🔴 Is there any negative of stickig the tube outside of the box.

[@rcwildman9255]

I have a question, it’s probably pretty simple, I have upgraded door speakers. That have a rms rating way higher then what the receiver puts out however it still sounds good. Now here’s the question, if I was to get a amp that correctly brings the speakers to proper rms ratings would it make it sound any better, or would it just bring the sound levels up without distortion or would it do a little bit of both?

[@clintmcmullen9061]

[@amanteapasionado6836]

You can even use regular ¼ inch wall thickness PVC and round over just the pipe. I used the pipe and put it on the board where I want it to be and trace the outside of the pipe, and than cut a square piece of wood and apply it to give the port hole a double baffle so the tube is very snug, so snug in fact I wound need to take scrap piece of wood to put over the tube to beat it down in and make flush with the wall. And in the inside ill take wood glue and make a bead around the port to give it an air tight seal after I round over the pipe wall. It works great with no port noise.

[@snipersouthsidesnipers2999]

Question: when using the factory head unit but upgrading the amp and speakers, how do you get around the the AVC-LAN lines (or CAN BUS communication)? For example if the Bluetooth or Navi’s voice signal is sent to the factory amp but you are looking to upgrade said amp? Any thoughts and input would be greatly appreciated!
