Step 2: Testing and Preparation

Before you design and cut the parts, you need to test that the system is working well, this is simple to test; hook up both speakers, plug in an input, add a power source and test! (Picture 1)

At this point I advise that you prepare the parts so that you don't have any problems after you've cut the acrylic.
What you have to prepare depends on your components, but for me it was the volume dial; it wasn't at 90o, so I couldn't put it flat on a laser cut box. (Picture 2) To fix this, I took off the casing this showed me that the volume dial was a separate PCB and could be moved to suit my desired location. (Picture 3)

If you had to modify your speakers in another way, please leave a comment with pictures and I will include it.
very nicely done ... looks very clean ... couldn't you use boiling water to soften the plastic to avoid smells from cooking it (maybe that's not a problem)
Yes, you could use boiling water to soften the plastic - it may even work better, as it might give more evenly distributed heating :D I used a oven that is well used and I didn't smell anything apart from the acrylic plastic.
Overall, this is a clever and well thought out design. However, I think the nuts and bolts showing on the front of the amp let down its generally clean lines. Given that they are like that to hold the case together, I'd suggest putting a false white front over these, held on with either supermagnets or double sided tape with a suitable hole for the volume control. You could leave a slight gap around the volume control and sandwich an LED between the front panel and the new front to give a glow around the volume control when the amp is on.
This is a good idea, but would a line of hot glue on the inside be sufficient? As it would require less laser cutting, but it would also mean that you couldn't take the amp housing apart as easily : / Thanks for the feedback, I will experiment with your idea and see how it comes out :)
Cool idea with the bowl for bending the acrylic!
Sansa + rockbox is the best.
I have a neat pack of Instructables to talk about, today on my Blog, and your's one of them! :) <br>http://faz-voce-mesmo.blogspot.pt/2012/11/instructables-traceparts-e-noticias.html
Awesome! Thanks for including it in your blog.
Beautiful design.
