2 omhs or 4 omhs
I have and old school Rockford fosgate 75 amp. Which one will sound better in a stealth box. The 2 or 4 ohm spearker.

Need more information on the amp.
If it's a 1 channel amp, the 2 ohm speaker will be better.
If it's a 2 channel amp, the 4 ohm speaker bridged
will be better. Either way 75 watts is pretty low.
(By speaker I assume you mean subwoofer)

The impedance of a speaker has absolutely nothing to do with sound quality. Asking if a 2-ohm speaker will sound better than a 4-ohm is like asking if a blue car will be faster than a red car.
The impedance has a big impact on power output. Assuming that the amp can handle it, a lower impedance speaker will flow more current and produce more output power. If the amp is 2-ohm stable, it will produce about twice as much power into a 2-ohm speaker as it will with a 4-ohm speaker (if the amp isn't 2-ohm stable it will just go up in a puff of smoke if you do that). Twice as much power does not produce twice as much volume - it will produce 3dB more volume which is noticeable but not hugely significant. You need ten times the power to double the volume.
So to answer your question... neither will sound better (sound quality) but the 2-ohm will be somewhat louder as long as the amp can handle it.
