i may try it and if it messes up, i will send back to crutchfield since they said it would work.
i copied this off where i did a search for it:
2 ohms speakers can work with some head units, mostly because the Kappa speakers are really 3 ohm, and not for very long. note that impedance varies with frequency. Infinity also attests that the stock wiring adds an ohm or so, so in the end, the load on the headunit is closer to 4 ohms. they argue that 4 ohm speakers are closer to 6 ohms at the head unit so a Kappa speaker is able to get rated power out of the headunits tiny amp.
you're dealing with like 15W RMS per channel of listenable volume anyway, it's not a lot of power. no one turns their head unit up to full volume while powering speakers because the distortion levels are so high with head unit amplifiers
