short definition going active simply means using active xovers instead of passive . active xovers use power ' in a car it would be your battery ' passive do not . and biamping and going active is not an either/or . if someone cares to explain more feel free , i,m on my way out the door .

going active means you biamp and use an electronic crossover, built in or otherwise.....(using a seperate digital xover is about as good as you can get).... I believe some component sets will allow you to biamp their passives... but active is generally the best way to go....
in some circumstances you can actually get more effective power biamping, sometimes less..... but the real advantage is the ability to go active.....

i have the MBQ RCE-216's. I run them active.
I tried single amp with the provided crossover, i tried bi-amp with the provided crossover. Then i tried my original plan, using a PhoenicGold MX2 active crossover and it sounds Much Better. I have a GM-5100T for each Door.
125 wrms for each mid and each tweeter.

Preferrably steep slopes. 18/24db.
Altough I do get away with 18dbs on my deck.
As far as x-over points, you should make sure you can bandpass on one channel. This is unless you are going to use the amps x-over. It's nice to have a bandpass for the mid anyway.

If you use a pioneer deh-p880prs, deh-p860mp or 8600mp, 960mp or 9600mp, you do not need an external crossover and do everything from the deck in pro mode. Set the HPF on the tweets, and notch filter the mids, and lpf the subs without using any crossovers on the amps or any external ones. probably the best bet for the money of setting up an active system without external crossovers (and you'll get better SQ because the external crossovers give more THD)....
I'll probably be getting one of those decks soon cause u can find them for 175-300 US and for the price, nothing can beat.
