    Custom Show Trunk DIY Thread

    Guest-only advertisement. Register or Log In now!
    Whether your on air or packing some major bass the trunk is the perfect place that allows you to put some creativity into your build. I know there are similar threads out there asking people to show off their trunks. But in my search I haven't seen an official one that asks people to document their build process as well. As I finish off my build for FixxFest I thought it would be a cool addition to have a thread that has some before & after shots and the in-betweens to building the perfect trunk with your own two hands. I guess I'll start:

    **Warning might be pic heavy.

    The Before:




    Not bad, IMO it's simple and clean but I wanted to build something a little more detailed and unique, so the journey begins.


    The Build

    I started with some simple sketches till I got the one I liked and I started from there



    First step was to build the wooden skeleton for the false wall and side pillars. I used 1x3 and .5" MDF for my materials.





    After getting them in a good place the next step was to fleece wrap the wood frames so I could add a few layers of fiberglass resin. I don't have any pics of the glassing and bondo process but it's pretty straight forward. I went with 3 heavy and hot (extra hardener) layers and 2 regular layers of resin over the fleece. One thing I learned was that instead off adding straight body filler to the glass panels it's much easier to make milkshake a mixture composed of 3/4 body filler and hardener to 1/4 fiberglass resin and hardener. It makes it much more runny to the point that you can brush it on avoiding massive clumps and pinholes. Also make sure you use quality body filler like Rage Gold to avoid hours of extra sanding.



    The next step was to start the side panels. The first thing I did was to make a wooden base shaped to fit in front of the pillar and snug against the carpet. I then stapled fleece to it and stretched it under the weather strip to form fit and over the trunk latch panel. I then taped everything up very well and added the same 5 layers of resin as above. I added a few layers of body filler, sanded, and I then trimmed the panels and test fit.







    The following step was to build the sub enclosure and decorative floor panels. I made the bottom base, sub rings, and support pillars at the angle I wanted. Once I was happy with the look I fleeced wrapped it carefully making sure I had no creases and I added 5 layers of resin and the two final resin layers strengthened by fiberglass cloth. I milk shaked 4 layers of filler and sanded everything to a super fine finish, topping it off with primer. I then cut out the decorative floor panels.




    template masking for the decorative panels





    Next I painted the sub enclosure and amp cover.



    I made a shaved trunk lid cover. My process was to tape everything up and straighten up the holes in cover by adding a thin layer of sheet metal to give it a new shape. I then added like 4 layers of resin and fiberglass cloth followed by 4 layers of just resin. I added 3 layers of milk shake and sanded that shit down smooth.



    As I finished off the trunk I wanted to add some trunk jewelry to my setup to mount onto my lexan glass cover for the wall. So I hand cut my cars logo/emblem out of 1/8" steel. I started with a print out and made a few cut outs from thick paper to trace the design and I proceeded to cut out the shapes. I then put it all together and polished it. Damn this was a pain in the ass.







    I finished up all the raw panels in black suede, mounted the lexan glass and emblem, connected the sub and here's where I'm at.



    I still have a few things to wrap up like lighting and some finishing touches but it's almost there. My car is getting painted now but when it's done I post up some proper final pics.

    I've always wanted to try a custom fiberglass box of some sort.

    You need to buy a shapoko, if you don't have one already, make those aluminum designs all over your car.

    @Mec I've actually been considering buying a desktop router for a while but I've never jumped on it because they all run on PC and my ecosystem at home is all Mac. That Shapoko thing looks pretty good. I might have to just bite the bullet and get a PC. I have gotten pretty good at designing simple pieces that are easy to cut with a dremel and jigsaw. But for complex pieces it has to be done right and CNC cut. I've found a good place in FT. Lauderdale that does some amazing work but that shit is $$$.

    I just did a custom steel emblem for my shaved engine cover.



    I'm working on the door sills now. I have them cut and polished but still debating whether I'm going to engrave or paint the design on them. Also gonna try my hand at bending steel or aluminum for a hardline setup but not sure I will have it ready for FixxFest.

    Do that shit man. It's not as hard as people would think. For your first design start simple to get the hang of it. The good thing is that MDF and fiberglass are pretty forgiving materials. If you fuck up you can easily shape it correctly with an angle grinder or fill it with more resin or filler. If you need help I can help you, just hit me up.

    Thanks man. Purple is definitely one of those colors you either love or hate. I wanted to try something different most people would be on the fence to run. I had done the murdered black look, black and red combo, black and grey, shit I even tried black grey and neon green at one point but it just didn't sit right with me. They all felt very familiar. I'm changing the car color to Nardo grey so once it's done I think everything will balance out and come together.

    Unfortunately im with him on this. You did fantastic work, and quality shows.
    I have to say i prefer the previous look with the sub box being more of a box than a circle.

    Also. It is not my place to say what to do to your car. But get that silly stuff off your air lines. Or at least get something harder so it will look even.

    I feel you on the chrome loom I'm going to try and get my hard lines done before FixxFest if I get the car back from the body shop with enough time. If not I'll stick to the black plastic lines and I'll do the hard lines right after. I actually tried to fit that box into the new set up (being a lazy ass) but since everything else had more organic rounded edges it felt out of place being hard edged. So as I sat there contemplating what to do, the circular box flowed much better IMO.

    Thanks man. When you work on your stuff throw it up here it would be cool to keep it going and see other people's build. If you need any help feel free to reach out I'll try to help you out if you need.

    I guess ill contribute my single picture. haha.

    I have since removed the soft line on the right side in place of a bent hardline that houses the gauge.

    The box that the tank is mounted on houses my 12" jl sub and amp facing the back seat. The carpet matches the trunk really well, but in photos it just looks so off.

    Looks clean man. I like how the lines twist into the tank. You also did a good job of balancing the lines so it's not heavy on one side. Did you tuck away the gauge? Also did you bend the lines yourself?

    This is my next project. If you don't mind me asking what fittings did you use? I read that DMPCF / NPT is the way to go http://www.airbagit.com/Airbrake-Str...ect-dmpc-f.htm . Also for the lines did you use stainless steel or some other metal?

    Seemless stainless 5/8th OD tubing. I used NPT / compression. The tank i bought was just NPT so thats all i needed. There are soft lines and a few PTC fittings under the hardwood. I didnt order them anywhere. There is a place called western fluids around me that sells all kinds of fittings for any project.
