Silly question because my brain has exploded.
Two pairs of speakers in each door.
Parallel or series?

wiring twin speakers
Depends on what Ω rating the speakers are and what load the amplifier is designed to work with.

i had the same problem i have 2 mids and 1 tweeter with 1 x-over and i wired it in series and it read 4.3ohms,
they were 4ohms each speaker i just tryed both way to see what loads i could get to suit my amp so just check it on the multimeter if you have one mind and see what you come up with. but make sure the load is spot on or higher than the headunit or amps lowest output load
hope this helps
cheers mike

Series 4 ohm + 4 ohm = 8 ohm 
Parallel (4x4)/(4+4) = 2 ohm
The 8 ohm load will be nicer sounding. It will be incredibly difficult to find a car amp that can run 8 ohm and it wont be running very efficiently if it does.
2 ohm wont be as good quality and most car amps will deal with these load and output more than rated power.
Either of this will be good for a head unit though if thats your plans.

Your calculations are correct but I'd go the other way. If he is running these speakers directly from a head unit and it's only rated down to 4 ohms he'll run a high chance of blowing it's amp. If he plays it safe and runs them in series it'll be fine but quieter.
If the speakers are mids and tweeters you really need to use crossovers of at least a basic low and high pass filters. If they're full range speakers I'd just stick with one.
