ppi amp connection

I have a PPI PCX2400 amp and (4) 10" Kicker L7's that are dual 2ohm coils What I am asking is what is the best and safest way to wire them to the amp, also the subs are in individaul boxes which are each .33 cubic ft and are sealed here is a link I found on the specs of amp http://www.audio-warehouse.com/web/mdl/PCX2400/detail.asp

You'll have to wire the voice coils in series PER WOOFER, for 4 ohms. Then wire the amplifier in stereo with one woofer per amp channel. (Oh sure everybody ELSE is going to say wire all the voice coils in series, (for 8 ohms) then bridge the amp, but that's more complex, and EXACTLY the same amount of power... And yes, it is a perfectly safe way to do it as well.)It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
