The formula is simple: product over the sum. This means that if you have 2 4ohm cabs you take 4 x 4 divided by 4 + 4

: : In order to use a 4ohm speaker with an 8 ohm amp you have to have 2 4ohm speakers and wire them in parellel.This will give you an 8 ohm cabinet. remember to wire in parallel. not series.

: Two 4Ù speakers in parallel will give you only 2Ù's, not 8.
