My fiberglass sub box build thread *heavy pics*
This will be my first "all fiberglass" sub box. Ive done plenty of research both outside and in this forum for instructions, tips, materials, cost and everything i still may have a few ?s as i go and appreciate any help or comments or ?s for how i did things every step will be documented and pics taken. So far all i have done is cleaned the car and taped off where ill be putting fiberglass i still have a few spots to tape and need to go 2in higher than where the box will stop. Ill get pics up tonite.
Sub box plan-
Its going to be a simple looking box but I want a single 12" fiberglass(7-9 layer) sub box, both the sub and amp will be recessed far enough to make it flat across the top. I plan on using a rockford fosgate punch amp and a pioneer 12" sub

Subbed!
Let me know if you have any fiberglass questions. I've done a few glass boxes in my day.

Will do. In fact i have one question after the fleece has been coated and dried do i leave the support legs in or take them out? and does it even matter if there in or out?

Re: My fiberglass sub box build thread *heavy pics*
well small update for the day got started on the recessed box for the amp its just a little bit bigger than the amp that way i can still fit my fingers in to pull it out if need be so heres pictures of the progress all wood is 3/4 mdf. By the way the box will be covered with carpet so it blends in with the rest of the interior

I have been thinking about doing this. What is the air space you will have?

Re: My fiberglass sub box build thread *heavy pics*
If the support legs are used for structure of the fleece having staples in them, I would leave them in. They won't hurt anything. The support legs for the mounting ring should be removed. I would usually just hot glue them in place. After the fleece sets up overnight, you can heat the glue with the heat gun and yank them out.

Re: My fiberglass sub box build thread *heavy pics*
I had 2 JL 8w7's they were so clean and loud in my old Towncar then my old Alero. They were louder and cleaner than 2 MTX 8500 10's. The advantage of the 8 inch is they didnt shake the car so, cleaner sound but was still very loud. I have seen what the12w7 can do to a car definatly not doing that to mine.

Re: My fiberglass sub box build thread *heavy pics*
I used 2 gallons on mine, you can save on layering with the fiberglass by doing enough to make it rigid and removable so like 3 layers then doing a bondo/ fg resin mix and mixing it up then rollingthe liquid around inside the box until its all coated, dries rock hard and seals perfectly, I've only done that once but it was pretty cool lol cuts down a lot of time layering
I like how this is turning out its good to see people aren't afraid of fiberglass lol can't wait to see the end result

Re: My fiberglass sub box build thread *heavy pics*
As far as an exact ratio idk I know its gotta be pretty liquidy though its more of a pasty fluid, one of the veteran installers made it for me, just one of the old school tricks that's been forgotten you gotta be careful though because if you use too much the light factor is gone, I did my box in the camaro with maybe 2lbs total of wood and then fiberglass and fleece coated with resin, the entire process is time consuming but if you're using a flat piece of wood for he top you save yourself a few hours already. I believe my box loaded weighs less than 25lbs but that's just a guestimate I never hopped on a scale with it

Oh yeah nitrile work the best and either do it outside or wear a respirator, and do not forget to get every single hair flat one tiny hair gardens to a razor Sharp point and at that point you have to let it all cure, sand it all then clean it amending the next layer, use a bright led light to shine on it they find the hairs the best

Im interested in this build as well... just bought a 87' Z-28. Thinking about a fiber glass box. What are the benefits over a MDF box?

Re: My fiberglass sub box build thread *heavy pics*
lighter, can shape it to the curves of the panels, not have to worry about if your measurements are right seeing as how you lay the fiberglass in the vehicle also if somebody had limited access to tools this doesnt require a whole lot

Re: My fiberglass sub box build thread *heavy pics*
I am actually in the materials collection phase of starting a big sub enclosure project. i am looking to put in two 10" subs and two amps in the sapce where the rear seats are. seats are out and will probably cut out hte carpet and lay down tape/foil right to the floor and build my base in the car.
Let me know how the fleece works and which resin you used. is it too thick to work with or is it just right and not flowing too much either?
with the fleece i see everyone always say to just make sure you pull it tight but i dont see how pulling the fleece tight can simpyl form all the curves for you. I've seen a bucn hfo enclosures where the subs are mounted at a "peak" and the fierglass around it slopes down on a curve. How is this curve achieved? or is a lot of bondo used for this?
how does the bondo work with the fiberglass box? do you just apply the bondo directly over the fiberglass once its dry? sorry, never used bondo before so just asking the very basic of all questions. hopefully it helps this post out and im not encroaching too much.
Thanks

Re: My fiberglass sub box build thread *heavy pics*
Looks great so far! Kitty hair can be used to add some rigidity, but it's a pita to get smooth. If I use it, I'll keep it on the inside of the enclosure. I'll start my thread here soon. I'm glassing in a 10 inch on the passenger side rear of the hatch. It'll be about 1.5 cubes sealed if my measurements come out.
How many layers of mat did you put down?

Carpeting as opposed to painting is much quicker and a lot less work mind you, and normally through our shop for a pro paint job we would still pay about 150 at our discount. It's a lot of work but the end result is awesome, I would advise against poof canning it, if you have a compressor and a paint gun you can do it yourself but you gotta treat it like you're painting a car.
