So I decided to build a sub box out of fiberglass because the trunk is too small for pre-made boxes. I'm only 60% done it but I thought I'd post some pics of my progess. After countless hours of labour and a trip to the ER for getting resin in my eye (lol.. the one time I don't wear safety glasses, soo stupid) here's where I'm at:

Here's the frame where everything started



The frame wrapped in resin soaked speaker fabric



Resin / Fleece layer totally dried .. in the trunk just to see how it looks



Inside of the box fiberglassed (pic taken the day after the ER)



Body filler aplied to the box .. it was hot out so I couldn't make it smooth .. now i have A LOT of sanding to do





More pics to come when I'm done some more....

Looking good mate. Nice work so far.

If it were me I would put a few more bracing pieces inside, fibreglass is good but it does flex slightly and with the weight of the subs inside and with hard cornering or driving in any potholes then it may move it enough just to crack the filler and paint meaning a repair job?

Nowt major though, just 1 or 2 from the sides to the sub rings and maybe a couple going between the rings also??

can I still do that now? .. should i just screw the brace pieces from the base to the ring (so its jus screwing into wood each time)

Well, as long as you cut it so that its a tight fit (But not overly tight that the braces bend it) then rough sand the fibreglass where the braces will go and just glass a layer or 2 over the top of the braces so that they are held in place with fibreglass.

You could screw them in but then you'd risk splitting the brace with the screw. I'd fibreglass it.

Let me know if you don't get what I'm on about.

looks great man, can i ask you how long it took you to get that far? thanks.

Way too long. I'm never doing this again lol well prob jus not for a long time.

Me being inexperienced with this stuff it took prob 5 days (prob 4-5 hours each day) ... I kinda stetched it out though cuz the process was takin too long .. now i just gotta be motivated to finish!

it will be worth it when you've finished it mate.

my rear lights took a hell of alot longer than that and a good 3 goes to get them to this stage. still need a bit of a change though when I can find the time.

diy stuff is something to be proud of dude.
