Just threw two x18 v.2s in my Yukon in a 15 cu ft box on an SCV4000. Very impressive, but I developed coil rub after just a month. It's really strange because there is no felt rub when you press down on the cone.. Actually, it only rubs when the coil is cold. After I pump one second of true RMS to it, there is magically no rub.. The other sub is fine. I monitor the clipping light religiously and the only time I see a red flash is on the attack peak of bass notes. From what I have researched, a slightly flashing clipping light is pretty normal and a fast flashing light is slightly overpowered. Solid red is clipping. \ As far as I can tell the sub is fine when played at loud volumes and only makes the VC running sound again when the sub is cold. I went ahead and ordered another sub just to have one on deck and am sending this one in for them to check out and hopefully warranty since its only a month old. Hopefully it just needs to be shimmed or something. Anyone ever seen a sub only have coil rub when its cold with no felt coil rub in the cone? Thanks!
