That's why I made a fatass boombox with a couple of friends. It was incredibly fun to build and the sound came out very good from the small speakers we got.
I really think you should try it out, as long as you can afford it. For the wood you should go for some Medium Density Fiberboard (MDF) since it is practically made for this. It's like fiber of wood pressed and boiled together until it reaches a very stable and strong condition, if I don't mistake myself. It's pretty expensive compared to other sorts of wood so be carefull while cutting it and be sure you get your meassures are right!
Good luck building, expecting to see pics of it when done
