Inherently, more resistance = less power.
If you have two speakers that are single voice coil 4 ohm speakers just hook them up pos to pos to pos and neg to neg to neg.
If it's a 2-channel amp then one channel for each speaker.
if it's a mono block (1 channel amp) then the pos from both speakers goes to pos on the amp and the neg from both speakers goes to neg on the amp.


-_-


so how much does 8 ohms cut the power?


lets make it simple....
2 100w subs in a series 4 ohms each making total resistance 8 ohms
200w amp

how many watts get thru the subs?

a general answer is 8 ohms will get around half the power an amp can provide at 4 ohms. this isn't 100% correct but as a general rule it tends to be right most of the time.

amplifiers have different ratings for different ohm loads. like lets say its 1200@1ohm 600@2ohm 300@4ohm then its probably around 150@8ohm. to find exact wattage in this situation is going to require far more effort than necessary since there is no reason to run a subwoofer@8ohms to begin with.
