the hardest part is running a couple of wires through the silicone boots in between the door and body. and even that is easy if you know how to do it... just fold one piece of wire (that's 2x's the length you need) in half, and slip the folded end through the boot, wiggle it in past the other wires, and pull it through. Cut the fold and you have two wires that are long enough to run to your amp.While I agree with the first part, I have to disagree with the other statement.
If you have half a brain (and independant control of the drivers) active will crush a comparable comp set. I've heard that active vs. passive argument about a thousand times.

Well, that's all your stupid passive crosses are doing. And now... now you get to fiddle with it from there to get it to sound better or more to your liking. Get too far off track? 4khz@12db. Bingo. Right back where you started.
It ain't rocket surgery.
