According to ohm's law; if your speakers are 4 ohms impedance

in series : impedance adds up = 8 ohms

in parallel : If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor so roughly =2 ohms.

rule of thumbs here say to match as close as possible the HU impedance.
