It also kinks up at odd times when Im doing different drills with it. Fully loaded not a bump in a full turn. They fitted my X3 2019 but had to unscrew completely the top two screws, fit it in, and then screw them back. First thing my millennial son-in-law said was "old school" and he liked them. I am not sure I gave Cambridge Audio full credit for how well these are made. Very sturdy and cute 5 stars for me. The Polk sub literally shakes the floor when at maximum bass. Return of the wrong size was easy. The price is very good and so far they seem to be very usable compared to blowing $600+ on thule or yakima. I have read about cutting the tip a little to improve the highs but Im not ready to conclude that its necessary to try it but will update the review if I decide to try.
