A near comprehensive list of materials needed:
- pair of speakers (mine were 3" inches in diameter)
- Lepai 2020a+ amplifier
- Dremel w/ sanding and cutting bits
- stereo mini male to stereo mini male cord
I found the suitcase on Craigslist for about $20. It's an old British suitcase from around the 1920s era, made of vulcanized fiber (http://en.wikipedia.org/wiki/Vulcanized_fibre
). The speakers I got at Goodwill at $15 a pair, but you probably wouldn't go wrong buying/finding a better pair. The Lepai amplifier I got from Amazon for around $25, but took a while to ship from China. Dremel I got for around $35 (actually a Black and Decker rotary tool) but if you have one you obviously won't need to buy one. Drill and screwdrivers I had, and the audio cable I got from Radioshack.
