kfr sucks! Yeah.... Can someone explain what bi-amping is please? And downfiring subs? Keep seeing it, not really sure what it means. BTW you know I was joking, right? Atleast concerning kfr. :)

Thanks for the pictures. 

Bi-amping means using separate amplifier channels for separate drivers or sets of drivers.  It usually implies an electronic crossover BEFORE the amplifier stage. 

Technically this is what you do with your subwoofer.  It is being run off a different amplifier channel than your mains.  It has a low pass electronic crossover.  You should also have a high pass electronic crossover operating on your mains.  This way the main amplifier and main speakers handle everything above the frequencies the subwoofer handles.  The subwoofer handles everything below the mains. 

When I say bi-amp the main components and a pair of midbass speakers I mean that you should do this division again. 

Amp Channels 1 and 2 = regular components ... high passed at 350hz.  

Amp Channels 3 and 4 = midbass drivers ... low passed at 350hz, high passed at 80hz
Amp Channel 5 = subwoofer driver ... low passed at 80hz.

So you see, each amplifier channel handles a separate chunk of the frequency range.  This relieves both the speakers and the amplifier.  Speakers and amplifiers operate cleaner and more efficiently (in general) when they are asked to do less. 

Now, after this brief and overly general explanation read that article I posted.  It will explain why bi-amping between the midrange and midbass drivers is so beneficial.

Thanks for the help guy's. After doing some research I have decided to go the Bi-amping direction with a Audiocontrol DXS Digital crossover.

Weee, I love informative stuff. Thanks guys. (THe downfiring was kinda self explanatory, just wasn't 100% sure. What are the advantages of that?)

AS for downfiring subs, I don't think there is any advantage over regular setup. The only one I can think of is if you have stuff in your trunk and you brake hard or take a fast turn, stuff may or may not hit your subs. You wouldn't have that problem with downfiring.

Well, yes it is one of the most expensive crossovers around but, I will be able to add the optional dash mounted control so, that I can adjust the settings according to the specific music that I am listening to at the time. I listen to a wide variety of music so, the ease and flexability of this crossover will come in very handy.
