i'm deffinately no audio buff, but here's my understanding of it
ohm's are the amount of resistance, or 'impedence'. its just a average rating, it wont run constant at the given impedence but will still only have about a +/- 1ohm difference from the rating at a given time. for instance 2ohms gives less resistance than 4ohms, and 8ohms is less resistance than 16, etc.
if you have a 4ohm amp you need to somehow get your speakers or subs to match it as close as possible, and there are 2 types of ways you can wire it, series or parallel. i cant remember which one does which but say your subs are 2ohms a piece, you can wire it to where you can keep both at 2ohms or wire it to where you can combine the ohms (2ohms a piece + 2subs) would equal 4ohms, 4 subs would yeild 8ohms etc.
i would think it would be safer (if the amp was running on 4ohms) to run the subs at 8ohms, which would reduce power output (almost by half) but keep the amp from overheating. and i dont think it is possible to change the factory amp ohm settings
my knowledge on this is very limited, and i only know what i know so far from experience with guitar amps and cabs so it may be a little different for car audio.
