High-End Speakers in Custom A-Pillars! How to build

You want to add a set of three way component speakers to a car audio system, but the problem is the factory doesn't have a spot to mount the tweeter and 3.5" midrange speaker. So how can I build a custom mounting solution for A-Pillar speakers? Here is how I built the custom set for the JL Audio C7 components in my dad's daily driver sound quality project.

You go to extra lengths on your builds and I know that you aren’t the only one doing this, but you are the only one who is doing it to this level on this medium and we who are watching know how much you care about your work quality. That matters!

[@timrudisill]

Mark, I've used headliner material like this in past builds also. One trick my upholstery buddy, that I get my materials from, showed me was to spray rubbing alcohol on the material and the foam backing will release very easily. The alcohol will evaporate quickly and you're left with a perfectly clean finish material to work with. I know it's not much, but I've picked up plenty of tips, tricks, and advice from your videos so I wanted to give back a little. Keep up the great work man!

[@michaeltorres2897]

A little advise for your body work.When the bonding has dried enough to sand. Before sanding,wipe bondo with lacquer thinner on a rag to remove the film of goo on bond before sanding so sand paper doesn't clog up.That will help you save more sand paper and it will actually sand So much better.Ive restore cars for 30 years so its tricks like that,that has helped me alot.Im very much OCD like your self.Good luck and I love to all your videos.Great work. God bless..

[@travezripley]

Michael Torres thats a great tip. Thnx

[@MrCbell57]

Its odd that many body men do not do this themselves. But it definitely will save you on sand paper for sure and that stuff is getting up there in price!

[@42cody]

I feel like this would make the bondo weak but you got the experience. I only worked with bondo for 2 years in highschool

[@rotweilerdc]

Eventually he’ll see this...

[@harj-spp8547]

The level of detail, precision and patience is something else. Another masterbuild in progress, cannot wait to see the compelted look. Well done.

[@earthonerealtors]

No such professional work found in the capital of India, Delhi, really really loved it

[@ToeCutter0]

Those A pillars look sharp! I’ve done dozens of them and Mark looks very confident doing them, which always provides for excellent results. I got into car audio in the 80’s (dual 10” subs in 1986!) and learned some hard lessons from installers who didn’t have the same degree of confidence.

[@NonPremiumID]

Mark, this was a labor of love for your dad. This is honorable.

[@lukeskywalker1836]

Always happy when you drop a new vid. Your attention to detail amazes a hobbiest like me. Have learned alot from you. Thanks for all the tutorials you do. Keep the vids coming.

[@travishill7873]

This is the perfect video for me. I have CT Sounds Meso 3-way set ready to go in my truck. I had the adapters which look really close to yours 3D printed. I just have to find the time to get it all done now. Thanks for another great video!

[@bsbabcock]

Beautifully done Mark. I'm going to bet this will sound spectacular. I imagine it will be AudioControl processed and powered of course. Should turn into a phenomenal system. Nice use of acrylic. Amazing how the usual fabrication materials have changed over the years from routed MDF to much more resilient acrylic. And gotta love those XT60's. The perfect little connector.

[@WireGuyGlobal]

Another Excellent Video! Thanks Mark for taking the time to show us your expertise. Its been Awesome watching your progress and growth. Keep up the good work!

I once had a ford transit woofer speaker and a tiny speaker out of a toy and wired it in parallel with the ford speaker and had them wired directly to a headphone jack, plugged it into my mums iPad and they both worked at quite a decent volume and sounded really good, there was a small capacitor in series with the small speaker I used as a tweeter

[@idriss.musa.]

[@lifeontwo2292]

i like the way you mixed that mixture to make sure the activator is mixed well

[@Spazwozzler]

Your woodworking skills are top notch, looking forward to see you work with the fibreglass!

[@AlexGifford5150]

Wow! I’m super impressed with your work. I really admire your attention to detail, I hope someday I can fabricate like you

[@jeffpessemier9802]

You’ve asked in the past for ideas of things we would like to see. I recently created A-pillar pods modeled after the ones you made your dad. I used the unfinished version of them for months before I finished them, but when I finished, to my surprise, the sound got much, much better. Anyway, that got me thinking it would be nice to see you do an example of how aiming the speakers can affect the sound using and RTA, and maybe an example of how finishing them affects the sound as well. I really wasn’t expecting much change as they have two+ layers of fiberglass on top of the fleece, so I figured that was enough density, but adding different fillers really helped.

[@ace1usmc]

You are a next-level artist. Absolutely gorgeous fabrication and design. Well done.

[@mr.schurr219]

And that is what professional work looks like.. Enjoyed watching it.

[@CarAudioFabrication]

[@jaistanley]

Holy crap: these look almost exactly the same as some sail panel pods I am making at the minute! I used photogrammetry to scan the car interior and built the pods in cad, and have completely 3D printed the first prototype. I made little grilles on the printer that attach with neo magnets and covered them with speaker grille cloth. They look sweet, but the design needs a little refinement before I do the final print and install (my cad skills are level: slow). I reccomend trying out Meshroom for photogrammetry. All you ned is a camera that you can lock on 'manual' mode so the settings for each picture are the same. Might make a lot of your fabrication easier? Nice one Mark.

[@Shawn_Magara]

Nice "Squeaks and knocks" he's got, all car jokes aside your work is the only work I idolize. You're marvelous at what you do. Keep it up! 😎

[@Camoburb]

As always, beautiful job. Really want to do something like that on my 03 dodge ram. Been somewhat happy for awhile with what I did but now I find i want more depth and volume. Maybe when I'm feeling brave enough I'll pick up a couple a-pillars and give it a shot. Will need new speakers though. My hertz are getting old and I'm sure wearing out.

[@williamlind2843]

I love your shop! I do not have the patience for this kind of work. I'm a Master Machinist by trade, but this stuff is like art work!

[@brettbrassard7959]

Great info Mark. I like that you showed us the way to do the edges. I had a door panel crack on me at the edge from the mid-bass. 2 T2 6.5" per door deadened to shit. I just didn't know how to do the edge properly and it was to week to take the beat. As always thanks for the time you put into the videos and the info you share.

[@farfromovin]

Brett Brassard did you mount the mid bass to the door panel (door card), and not the door itself?

[@brettbrassard7959]

@@farfromovin I fiber glassed everything to the door panel without adding mounting to the door skin. Plenty of ccf between everything just didn't make the enclosure solid enough. I was my learning curve, next time will be way better and more solid.

Bravo,molto bravo,complimenti per l’ingegnosità nel progettare e realizzare il sistema tre vie soprattutto midrange e tweeter. Complimenti.

[@brandonxtreme9887]

The cheat code for separating the foam from the material is ,do it in hot water, comes apart easy 👍👍👍

[@Mr.GettingItDone]

Hey hopefully you upload a video, about how to set the gains in the amp to the 3 way speakers. And the accurate equalize on the system.

the interior plastics on my Odyssey are trashed. I planned to primer and spray paint it but this gives me another option, thank you!

[@ronalexander4955]

Thanks for sharing your knowledge.

[@mikka1986]

Some tips, after the resin cloth dried, cut the plastic behind the cloth wide enough for fiberglass to goes in. Fiberglass from the back save a lot of sanding time and also better maintain of the shape form by the cloth, it is stronger on the baffle edge and doesn't crack easily. Another tips, for resin or putty to stick to the plastic, you should prepare the surface by sanding it with high grid until it is rough to the touch.

[@cmar4076]

Looks SHARP man! 👍🏻

[@chaseleim4773]

I feel, that 2 6.5 8's in a t line would suite this build perfectly

[@audiohutch]

Can you make the acrylic piece with a 3D printer? It won't be as solid but if you need to use it just for a shape then I don't see why not. It can also allow you to skip the steps for gluing pieces together and also adding the wooden dowels.

[@farfromovin]

Looks good. I like they’re mounted on the same plane, and I agree they’re fancy grills to show off and be proud of. What’s your thoughts on enclosing the rear of the mid?

[@jonblakk73ab]

Have you ever done an install in a 4th Gen camaro,I want to do a component set in my mines but I don’t want to cut into my doors and or a pillars for the tweeters,great vids as always

[@Viralsmells]

Always a good day when there’s an upload 👌🏻

[@steve5642]

Please direct if you've addressed this previously. In a 3-way system, is the pillar always preferred vs kick panel for mids/tweeter? Is it based on active vs. passive tuning? What's your take on overall 3-way speaker placement for best soundstage (right/left & vertical)? Thanks! Great vids.

[@1showking]

Quick question... How did you get the upholstery to sit inside the edge of the acrylic without wrinkling? The video shows the wrap and the cut, but not that one part. Great work as always.

[@Boxboys.Audio.Sound.Solutions]

I always enjoy watching your videos !! What would something like that cost in your local market ?

[@zachpangos7159]

Hey, I love this build. I am attempting it myself. What connectors are you using on the cables and where did you get them?

[@selfbuiltrods]

Would you consider selling a set of these pods? I too have an equinox that I’ll be mirroring your setup on. I’m glad I found your videos. Thank you for sharing with us!

[@Bhagatdeepfull]

Excellent video bro, i really appreciate ur work and i wanna thank u because i have learnt all the basics and expert stuff via ur videos, i need a little of ur expert advice. I have Pioneer 80prs and want to use active crossover setup, what components, amplifiers and sub woofer would u suggest? I love crisp and clear soundstage, with detailed separation of instruments. Currently i have Amplifiers: Pioneer gm 8604 & JBL GTO1004, i was thinking to upgrade my speakers! Would these amps be ok or do i need to upgrade them? Thanks in advance for ur precious advice

Just a suggestion: could you number your videos and state what videos are next to make it easier to follow? fantastic work

[@catalyst470]

can you do the super budget build please idk what speakers are good and i dont wanna buy somethin bad

[@deemanefinneymane4920]

what I want to know is what the best amplifier to use on these c7 speakers jl says the vxi 800 or xd 800 but those amps amps do not apply the correct rms rating for them so technically ur not gonna get the best out of them using 75 watts per channel and if u bridge the amps for the 6.5s u are applying 200 watts to each woofer so that's 25 watts over powering there max rms rating.

[@AF_1892]

I started w a dinky 350 watt amp with a ported 15 rockford fosgate punch sub. It was 16. A guy with a crush on me paid a really smart physics guy. He calculated the acoustics so perfect. Anyways now I regret putting 10's (Rockford Phosgate punch 2's). I should have done 12's. Decks and mono D bass amps all Kenwood. Rockford for the mids and mid speakers. Infinity reference are also great for replacing factory speakers. Most of my equipment still works and its 17 yrs old!

[@tapiotukiainen2500]

Wouldn't it be better for the speakers to be in a symmetrical angle to the listener than symmetrical to the car?

[@SuperBallin100]

Great Job! Looks Badazz....

[@chadstockton4948]

what thickness CA glue do you use? I noticed you used it on the corners for the rounded stacked corner down fire sub enclosure as well. Do you use different thicknesses?

[@forklift385]

so want to do this now with my Audiofrogs, thanks

[@robinong5803]

Nice video Mark, want to ask u whether is it necessary to stuff polyfill into midrange? Thanks

[@TheDarryledmonson]

Mark can I use the Focal speaker pods? I would to place them in my Surburban and tilt and aim them to the doom light. Then finish it with cloth and fiberglass like these.

[@beardedgaming3741]

i prefer to use grill cloth as you have but not add any more fiberglass to the outside. i come in from behind with chop strand and resin, brush or pour it into the form and then add bondo to the outside. it saves sanding time as glass matt adds quite a bit of surface imperfections where as the grill cloth is smooth. i do add milled fiber to the resin when i paint it into the grill cloth. it self levels well and sets stronger than just resin alone in the cloth.

[@keathflohr2480]

AWESOME VIDEO!
