I won't post the pics here, but you can see them on my site
below. All laid out nicely in thumbnail format

Here's a direct link for the lazy bastids

Anywho, a few things I'll mention that you mignt not figure
out just from the pics alone:

- The white foamy thing is just a sponge like material that I found
at work in some box. I wanted to see how it sounded with and
without it in the box. Conclusion? Hard to tell but no drawbacks.

- For carpeting the side of the box, I glued carpet on a
bristol-board type paper first. This made the edges smooth.

- And I was about to buy contact cement ($5) or 3M Super77
adhesive ($15) when I decided to try using a glue gun,,which
I happend to have cuz my sister uses it for her crafts and stuff.
It dries fast so you gotta apply in chunks at a time but it works
wonders.

Some figures of what I spent on making the box (Canadian dollar):

1) $11 for a 4ft x 2ft x 3/4" MDF sheet (cut at Rona Hardware)
2) $2 box of 2" drywall nails
3) $15 for fabric/carpeting (150cm x 100cm sheet)
4) $1.80 cauclking
5) Silicon RTV (blue stuff), glue gun, carpenter's glue were already
in the house so I'm not aware of their costs.
6) Got Roto-Zip from co-worker to cut circular hole in box
7) $600 for Subwoofer/Amp/Kit
------------------
Total: $629.80 (prolly $640ish with 5) above)

Overall I'm happy with my build. The edges are still kinda visible
on the carpeting but it's nothin ghetto looking [img]smile.gif[/img]

 

Looks good. [img]graemlins/thumb.gif[/img]

Looks pretty good. I don't know if it was your first time at it, but if it was, good job.

 

First (own) car, and first time installing and
having aftermarket sound system.

Obvously the next time I make something it'll
take less time and effort. [img]smile.gif[/img]

 

Looks very nice. You did a great job! Your box however looks like a perfect square. I didn't think you were supposed to make your box completely square. I thought you were supposed to have at least one side angled? Good job for sure though on the carpet!

 

how does it sound????

 

It's good for your first try! the only thing I might change (now that your done!) is the orientation of the amp...the badging on the amp may be alligned properly (so you can read it) but the heat sink is what you shold concern yourself with.
Heat rises, plain and simple, and an amp is way more efficient when its cool, way more. What I suggest is that you allign the heat sink up and down (vertically) that way, the heat wont get trapped in the upper sinks, and instead it will flow upwards and away! Thus, a cooled louder system! Who can argue with that?

P.S.

and yes the box should have atleast one unparallel side, that way the sound waves cant (possibly) bouce directly back and cancel each other out. It isn't written in stone, just a good idea!

The box isn't square. I made sure that it wasn't
square after reading a few books. Also the
sub is mounted offcenter. I'm surprised you
guys thought it was square after seein the pics.

The exterior box dimensions are:
16" x 10.75" x 13" (WxHxD)

And I've added that foamy material hoping to
disperse some of the standing waves.

I'll see what I cna about mounting the amp
elsewhere to better disipate the heat.

Thanks...
