Honestly...for $350? I would be all over craigslist and ebay...
I got 2 12" JL Audio 12W3v2 for $100 in a 3/4 MDF custom sealed box. They sound awesome for $100.... This would solve your issue of building a box.... craigslist has tons of stuff, and you can go listen to it before you buy it most of the time. Make sure the stuff works.
You want a sub, amp, and radio for that price if I read that right? I would say sub/amp yes. Radio.... $80 dollars VR brand at walmart new. Plays mp3's and all that stuff. Maybe a decent Alpine or Pioneer off craigslist or ebay for under $100.
All good advice so far, just adding a few more things. This is basically what I did at first was buy some good stuff on craigslist to get a decent system. Then as I got money I replaced it with better stuff.....so on and so on it goes.
