Alrighty.. I need another wiring diagram for a setup..

Quanity: 10 (ten) Single Voice Coil 4ohm (10") subwoofers rated at 400w RMS
Quanity: 2 (two) 1 ohm stable amps

Amplifier specs are as follows (150w x1 @4ohms / 225w x 1 @2ohms / 400w x 1 @1ohm)

Whats the best way to wiring these up? I'd preferably like to use 1 amp per 5 subs if possible. (please explain in detail or draw a diagram if possible)

I know this is far fetched and prob. stupid, but again its another stupid project Im playing with in my spare time.

Thanks!

QVC wiring is a thread that has some information you should read; four coils can either be on one sub or they can be on four subs, which is your case.  Think in terms of sets.  Even numbers work, odd numbers don't.  Try imagining using just eight of those subs and you'll be on an easier track.  Enter 4 ohms into four windows of that parallel calculator and you'll see what you can do with eight subs and two amps.

Alrighty, looking at the amps I noticed one more thing.

These amps are cabable of running a Master>Slave wiring setup

Being that its best to run with even #'s, could I pair the amps together and wire all 10 in this way?

Being with that said, I'll need a guru to write me up a diagram if possible :)

Thanks

Using 8 of the subwoofer will be better on the amps and better for you.

Can't figure it out with the calculators, tuscani?  Here's what you can do if you can connect the amps so that you have the equivalent of one amplifier instead of two: 

10 can be divided by 5 or 2.  You have to arrive with an equal configuration of sets that when added together amounts to 10 subs total (you can't have 3 or 4 subs per set, for example).  It is almost always necessary to figure series/parallel wiring with this many subs, so divide the subs into sets of 2 each and you'll have 5 sets.  Wire each set in series, then parallel the sets.  Impedance is about 1.6 ohms.  Each sub will get maybe 60 watts.
