No worries at all, glad to hear it worked! Funnily enough I've not even had the problem, just passing on the info. One difference might be that I've taken every single Harman Kardon speaker out of my car and only have Dynaudio splits up front. Maybe the rear shelf HK speakers contribute to the rattle?
