Looking to get a midranged car stereo system.. nothing with too much power but something that is decent. I already have door speakers, just infinity reference speakers, they sound pretty good.

Head Unit Looking for suggestions for this, I would like a deck that plays WMA and mp3s, has decent power, around 200$, and has sub preamp outs. I was looking at some of the new ones coming out this year.
Sub Alp 12" DVC or Infinity 12" DVC dont know much about the second sub.
Amp 350W @ 2 ohms Alp mono
Alarm offers many good options, and comes with a 1500$ "insurance"
Box This is a downfiring box, good size.. debating whether to get this box, or look for custom build, or if it is that big of a deal.

Thanks.
