Might also help when removing the tweeter cover and then the tweeter to insert some noise dampening material (think memory foam mattress topper piece about the size of a nickle) into the hole where the mirror wiring runs through the "Triangle" where the rubber gussetts are.
As a newbie to Subi with a used '01 LLB OB 3.0 90K, I am open to any info, suggestions, resources, MAINTENANCE, issues etc to look out for. Thanks
