About: Hi, my name is Ulrich Retief. I am currently a fourth year medical student at the University of Stellenbosch in South Africa. Although I am very busy with my studies and extracurricular activities, I love t...

I am quite finicky when it comes to sound. I am the person that would rather not listen to something at all if it is not going to have proper sound. Living in student housing at university, this is often a problem, because people are always pulling out there phones to play something and I can't help thinking: why don't you just use earphones or something, it will sound so much better!

So when I found out that my brother's old car speakers have been lying around the house for the past 4 years, I immediately felt that it needed to be used. So I built a box for them to take to my housing!

Step 1: Collecting What I Needed

The great part about this project, is that I literally did not spend a cent building it. Everything I used was either trash or leftovers from previous projects.

In these pictures you can see the DIY fitting my brother made to put the speakers in his old I got the wood from my dad. He does renovation in houses and at one of the jobs he did, he took out some quick fix shelves and the owner asked him if he could take it to the dump with the rest of the trash. Dad agreed, but thought that it still had potential and that's when I found it.

The screws, glue, wire and paint was all just in our garage from previous projects.

I thought this would make a nice 'ible from the start, but I was really excited to see the trash to treasure competition, 'cause this falls in so perfectly!

The design idea I added here was my initial plan I had in mind. It really helped that I already knew what would I was using. I usually try to first find the wood and then draw up a plan rather than other way around. When I use refurbished wood, it always frustrates me if it doesn't work out according to my plan, but since I started doing this, things are going much smoother.

I decided to make a single piece instead of two boxes because it is much more practical in the setup I have at my student housing.

PS. I use Tinkercad for my planning. It's free, simple and very easy to use!

Step 2: Finalizing My Plan

After coming up with my initial plan, I came back, cleaned up the wood a bit, took off the supports and refined my plan. I made very few changes, mostly slight changes to the position of the divider inside and the shape of the vent.

I eventually cut up the original planks to have the following

  • 2 x A: 27 cm x 50 cm (10,63 inches x 19,7)
  • 2 x B: 27 cm x 13 cm (10,63 x 5)
  • 5 x C: Exactly the same as A, but without the holes
  • 2 x D: 27 cm x 60 cm (10,63 x 23,6)

Just to explain the odd sizes, the planks were already 27 cm broad, so I just planned everything else around that. The size of B was just a square that I cut in half. The purpose of this piece is to channel the bass from the speaker around and out of the vent, which makes a significant difference in your sound quality. Just make sure that it covers about 1/2 to 2/3 of the depth of the speaker.

Step 3: Cutting to Size

Because it is awkward to work with big pieces of wood (especially when you are alone), I started by measuring the pieces so I can cut in the middle but still have some off cuts on the side that I can use to cut the final pieces more precisely.

Piece D is the top and bottom pieces, and I was working theoretically that it had to be 60 cm. So before cutting them to size, I just checked if it would work by using some of the other pieces and just packing it in position. Once everything was cut to size, I gave it a light sanding. (Didn't worry too much as I was painting it)

Step 4: Cutting the Holes

After sanding I took apart the speaker fitting my brother built. I drew some lines on my A pieces to figure out the exact placement of the speaker hole and the vent. The reason for the smaller measurements on the speaker hole was to make it easier to see when I placed the speaker centrally.

I drilled a few holes in the speaker hole then used a jigsaw to cut out the waste pieces. I used a hole saw for the vent.

Step 5: Drilling Pilot Holes

I drilled pilot holes around the edges and on the front where the divider had to attach. (It needs to be just above the vent.

I also drilled larger holes where I was going to use dowels at the front and at the back of the center piece as I could not use screws there.

I also drilled holes in the back pieces close to the center where the wires of the speaker will come out.

Step 6: Assembly

I started by gluing the dowels and then attached the side panels. When it was all stabilized with clamps I inserted and attached the dividers.

Step 7: Top and Bottom

Once the initial assembly was semi-dry I attached to top and bottom then left it all to dry properly.

Step 8: Painting

I simply sprayed the entire piece. While spraying I decided to add two of the supports that was on the planks when I got them as feet for the piece to stand on. It is much easier to make it stand stable when it has two points where it touches the floor than having the entire bottom touching.

Step 9: Wiring

At this point it was simply attaching the wires to the speakers and screwing the speakers into place. I decided to use the wire connectors as it comes out of the box, because it is easier to transport without wires hanging around and it is much easier if you end up wanting to use a longer or shorter pair of wires.

Now all that is left to do is hook it up to an amplifier and blast your favorite song!

Step 10: Done!

It has been such a great time having these in res! Everything is better, from just playing music to having a movie night!

PS. If you want to know how I took the picture: I used a black duvet cover, put it in a dark room, opened the camera shutter for 30 seconds and used a flashlight to illuminate to box. Let me know if you want a more detailed description! Maybe another instructable?
