What is the formula used to determine the resistance which will be presented at the voice coils of the speakers.

Series: Rtotal = R1+R2+R3...

Parallel: 1/Rtotal = 1/R1 + 1/R2 + 1/R3...

Oh and your terminology seems incorrect - the stuff I posted will derive the impedance presented to the AMP based on the impedance of the drivers.
