Title says it all. This was a long project, and working with fibreglass is kind of a pain, but the end result was pretty good I think.

Sound wise, not great since I wasnt doing any calculations, and I went for a sealed rather than ported design - but hey ANY sub is better than no sub!  :shifty:

 

To build it, I largely just followed what Cole did here: 
 

 

moulded the fibreglass base to the wheel well and let it set, then added a few more layers, cut some plywood, made a hole for the sub driver, and screwed it to the shaped fibreglass with some broom sticks cut to length to make the frame:

Took a large cloth and tied it over the frame nice and tight, and applied a lot of fibreglass resin to harden it. Cut off the excess cloth, and cover it in lots more fibreglass and resin to make it hard. Sanded it down to smooth the surface and ensure it still fit, then glued some flooring carpet a neighbour chucked in the bin and viola! One custom sub box for the mini boot!

Interesting. How have you secured it in the car?

not too bad, but not great either. Im not looking for punchy or boomy bass, but most of the bass doesnt travel into the car cabin from the boot. Im slowly playing with the tuner and the gain settings to tweak it.

Two L brackets screwed to the plywood and the back of the boot that the rear seat fits onto, but to be honest, if you've moulded the sub to the wheel well nicely it should just fit in perfectly without any fastening. The fastenings are more for peace of mind in case on a hard turn the heavy sub driver causes the box to somehow tip over.
