sealed, it will work well, but not as well as a larger, ported enclosure. Regardless, it doesn’t take up
too much space, so it could prove ideal for most people.
If you have no experience with speaker design I recommend that you get your local ICE dealer to
build this enclosure for you, they will also be able to finish it in carpet for you so it blends in well with
the rest of the boot.
If you are really serious about the sub, then read on. I have designed and fitted a ported sub
enclosure to my car with fantastic results, if you want to do the same then here’s how I did it:
First of all, I wanted a solution that would accommodate the sub as well as provide somewhere to
mount the amplifiers, my 4 channel amp is quite big, so finding a place to put it has always been an
issue. The first thing I did was to remove the spare wheel in order to free up as much space as
possible. Once I had the spare wheel out, the natural slope of the boot gave me an idea. I decided to
use that natural slope to accommodate the sub enclosure, I started sketching ideas and came up with
this design:
The idea is that the bulk of the volume required for the sub enclosure is spread out through the
natural slope of the boot floor, this can be topped off with a flat shelf, effectively giving a new flat
bottom to the boot. This would be an ideal spot to mount the amplifiers and, although the sub
speaker will be exposed, it can be covered with a grille so the boot can still be used for occasional
luggage.
On paper the concept looked good, but I thought it might be a bit tricky to build. Luckily I know a
friendly carpenter and he really helped out, showing me the easiest and quickest way to do it.
First of all, you need to make some templates, use some cheap, thin fibreboard for this, cut this
approximately to size and then mark it out accurately and trim it down in-situ until you get accurate
templates. Start off with the bottom, then build up the sides. This stuff is really easy to cut, but a
Black and Decker Workmate and a decent jigsaw make the job even easier. Once you have the
templates, make the bottom part of the box up in 15mm MDF (medium density fibreboard), then
make up the sides using the same material and get them screwed together. Place this in the boot to
double check that it fits. Aim to make sure that the top of the box will line up with the natural shelf
either side of the curved bottom of the boot.
Now you need to create a top for this box, this top part will be bigger than the size of the box you just
made, take it right out over the natural shelf either side of the curved boot bottom, so you end up
with a flat floor right up to the full vertical sides of the boot. Again, use some thin fibreboard to make
a template and then make up the final piece in 15mm MDF. Make sure that the subwoofer will fit into
