3 ohm speakers

What's up with infinities 3 ohm speakers? My amp runs at either 2 ohm or 4 ohm so will my amp round up to 4 ohms? I have 12g wiring going straight to each speaker from the amp.

If your amp is 2 ohm stable it should safely handle a 3 ohm load. Power-wise, the speakers will receive somewhere between the two. So if your amp does 50W RMS @ 4 and 100W RMS @ 2 you'll probably end up with something closer to 75W RMS.

Ok so the amp doesn't have a hard switch between 2 & 4 ohms it can sit anywhere? So say a speaker is 2.5 ohms the amp would work at 2.5 ohms also?

Yes. The impedance isn't determined by the amp, but what's wired to it. You could even stick multiple speakers on each channel (though the power will be divided evenly among them) so long as the final load is about 2 ohms minimum (at least for this amp). When people wire odd numbers of speakers together you'll see weird final loads (i.e. 3 4 ohm subs wired in parallel gets you 1.33 ohms). Provided the amp can handle that low of an impedance it'll work just fine.

Ok interesting. Well thank you for the clarification.
