Unless you had the volume maxed or the gain way high, the rms rating of the sub is not what caused the fuses to blow.

But in regards to that, it'* highly unlikely that it'* a d1 sub but if it turns out it is then you got reamed on that deal cause no way in hell should a 1 ohm coil read 2.5x more. IIRC, Fi spec'd a D1 coil out at .7 ohms so you should be very close to that, anything more than half an ohm +/- of that value would throw up a red flag to me.
Even the D2'* don't read as high as the reading you got, although I wouldn't be too terribly concerned about your 2.4 reading if it turns out to be a D2 sub as it'* within a half ohm. But IIRC, Fi spec'd the D2 coils at 1.7 ohms, wire the coils in series and you'd end up with a 2.4 ohm reading. That being said...............
Since you made a thread about how to ohm a sub, LOL, i'm questioning your measurement. Any time you ohm out anything it should be "out of the circuit", so on your sub you want to make sure that your coils are not connected to each other at all. I have a feeling the coils were still wired in series when you ohm'd them out, thus giving you the identical reading of 2.4 ohms "on each coil" when infact you were reading the sum of the coils on each side.
