Whats the difference between 2 ohm and 4 and whats the sound difference

I believe the "subs" are wired in series which presents a 4 ohm load to the sub amp, which is more than likely a mono amp, hence the series wiring. There is no difference from a sound standpoint between 2,4,8 ohm speakers. The impedence is selected to meet certain design and installation requirements.

If you buy a sub with a 2 ohm impedence, you will need to make sure your amp is capable of 2 ohms. If you buy an amp capable of 2 ohms, you can use either or 2 or 4 ohm sub. Also, if an amp is rated at 100W @ 4 ohms, it's going be roughly 200W @ 2 ohms.
