Ohms are important, but not really. Size of the speaker is important but not really. Just get as close to the original as possible
right size and don't go overboard on the watts should do the trick. I'm also looking at possibly putting in those baffles in may help with the rear bass response... then again I heard that they won't.
If powering speakers from the factory indash, the replacement speakers should be between 4&8 ohms. Will you have a problem with 2 ohm or 10 ohm speakers? Maybe, maybe not. The further you stray away, the more likely problems are to occur (fortunately most all automotive replacement speakers are 4 ohm) As far as size constraints are concerned, anything different than the original will require a bracket or EXTREME modification. Sure aftermarket manufacturer product sizes vary for a certain segment (ie 4" speaker), but it's generally very small variances that don't cause fitment issues.
People generally think a speaker capable of handling more power is a more desirable speaker (ie a 200 watt speaker is better than a 100 watt speaker). Two things worth mentioning, don't look at the max rating, rather the RMS rating (if that rating isn't readily visible/available, move along). Additionally, a speaker capable of higher
rms power, ACTUALLY NEEDS THAT POWER to achieve peak performance. With our Spark, like most oem head unit amplifiers, power output doesn't exceed Watt figures in the teens, so a lower rated speaker isn't a worse choice.
Regarding baffles.... a speaker "works better" in a WELL DESIGNED enclosure (does a much better job producing lower frequencies). Putting a baffle on, may or may not improve sound quality/frequency range.

lol What is up with this car and the audio system? Bah. I may end up taking it in to a local place and just having them dump some upgrades into it but I'd rather just put the speakers in myself as it'll be much cheaper.
Fortunately or unfortunately, the Spark is a sub compact economy car. There's no practical place for large audio components, and GM wasn't putting out to design a system capable of delivering a full range of sound.
I'd put some speakers in myself and save the cost of labor. Then maybe decide if it's good enough, or whether a subwoofer is necessary (hopefully just a small enclosed & powered deal is all you "need", to get desirable sound).
