Pretty nice stuff there. I'd probably pony up the extra money and just get the sub(s). You'll be able to find resonating areas in your car easily and you'll have some deadener available, unless that was all going to your doors.
Since you're going active, I'd look at these drivers. Yes, it'd be stretching your budget further, but it may save you money in the long run.

The Dayton Audio reference stuff seems nice too, but the 7" woofer can't be crossed high. Something like the Peerless HDS tweet could handle that, though.
