how to run 40 12 2ohm quad voice coil's

If your number of amplifiers is known (10) and your number of subs is known (40) then you don't have to worry about driving 40 subs, you only need to worry about driving 4 subs (40 subs / 10 amps).

If you amps are monoblock amps you can wire each coil in series on the sub then parallel the 4 subs to a single amp - that will give a 1 ohm load.  If you amps are stereo amps and only one ohm stable wire two sets of coils in series then bridge the two sets giving you a 2 ohm load per sub.  Then, wire two sets of subs in series and then wire the sets in parallel.  Bridge them to the amp for a 1 ohm load.
