I am looking to create my first boombox - something particularly loud as hell. My buddy created this http://birchacoustics.com/fullrange_009.htm in high school and is now selling crafted speakers. Was wondering where I should start? Any help is appreciated!

well to be fair buddy you either want a true vintage boombox with everything made in there from the factory or you want to create your own,my personal preference is to a factory made one,not a frankenstein box,of which a good starter box is a sharp gf 8989/9797 that kind of thing

I think if I were to create a DIY boombox I'd have to have classic styling but modern more powerful components...otherwise you may have a boombox that pounds but if it looks like a shoe box with car speakers I wouldn't use it.  The ideal would be to take a dead boombox that still looks good and fit all modern gear in it...it would have to be done sympathetically though, I don't like the 'stick a car radio in a boombox' approach as it just looks cobbled together imo...needs to have a professional looking finish

You might be on the wrong boombox forum. On this forum, we mostly talk about factory made vintage boomboxes, not homemade ones with mostly only speakers and a car radio.

Like these:

Still, you're welcome though ;3

So what are some great sounding factory made boomboxes out there other than the ones mentioned - could you inform me on some of the most popular boxes out there? Thanks

Also, if someone could point me to a thread explaining the science and number crunching of audio frequency, impedance, dB, etc. This would be great

Thank you very much retro for your response!
