i've seen this done but its a very time consuming process and the fibreglass work is a pig. i know of people that have made an mdf cone and then fbreglassed that to fill the recess so its easier to remove if/when you sell the car.
Mercedes b class comes with a sub in the spare wheel compartment standard might be a bit big for a nova though
nice hair there niek, and sub project
your kid seems enthusiastic to learn
to gibbo that started the thread, what you decided ?
you could always get a wee 8 inch in a custom box, and tuck it to one side out the way.
or you could be ruthless and tear out the back seats to make ultra boot space.
Sorry to bump this.
How much resin and matting did you's (that have done it) use?
Does anyone know where I can have a sub box made to fit ski or might have a go myself. Daft question but how important within reason are the dimensions???
A subwoofer needs to "see" a certain volume (in litres) to work properly. Do you have specs on the sub? The spare wheel well holds roughly 22 litres give or take. As for the level of difficulty: it's doable given the right tools (old brushes and rollers) and materials (matting, resin, hardener, mould release wax, tape). If a numpty like myself can do it, pretty much anyone can.
One day I'll start a build thread. One day...
