These are not 6.5, but more like 6. In fact that's exactly what they are, 6, it says it right on the box 6. And this makes a very big difference, on whether or not I can install them. I already bought boxes for the 6.5 subwoofer, and these won't fit as is. One more thing, these have two voice coils, and not one like the description says.
