Unless I am going WAYYYY astray somewhere, the 240 did not come with components at all, so there was no X-over stock for you to even consider. This means that YES you have to use the box supplied, and you can only hook 1tweet and 1mid up to each box. Have fun drilling holes for the tweeters, it is actually quite easy, just take one of those drill bits you use to make holes in doors (make sure it is a small one) and put them in the doors above where the A/C vents are (it is very flat). I have people ask me if mine are stock all the time. Oh, and good luck, it is actually very easy.
