Jbl came out with these 2 ohm speakers and other companies also have come out with speakers with loads under 4 and in all the HU manuals it says use speakers with 4-8 ohms my uncle bought a couple of these but sometimes they were hard to sell because the customers didnt want to buy an amp all the time and then he sold some to this technician and he started putting them to the stereos without any problems and he also said the stereos circuitry can handle it but what do i know i dont fix stereos and hes been doing it for like a year now without any problems but only new after market stereos any opinions?

Some punctuation might be nice. 

Not all head units will support a 2-ohm load but some will.  Almost NO factory heads will support a 2-ohm load for very long.  Some of the new speaker systems rated at 2-ohms are actually more like 3, by the way.

Infinity, who also make 2 ohm speakers, have a write up that I can't find right now but I'm sure its on their site somewhere basically it says this though. The impedence of the speaker is actually closer to 2.67 ohms and when you add the resistances of the connections and the wiring it generally goes up to around 3.2 ohms which they say is safe to connect to any radio factory or not. These are their words not mine but my thinking is it's just a ploy to make their speakers sound louder at a given volume and since to most consumers louder is better they will choose them every time. hope this helps.

I believe ferret is correct, you may also find that after a period of time, the voice coil in the speaker will begin to heat as it plays.  So you may also see a small increase in resistance from that factor as well.
