Front Speaker Grill Vibration

[Kaitsuni]

Following on the advice in a parallel thread, I replaced the stock speakers. The quality of the sound did improve a lot after the upgrade. But one annoyance remains: the front grills are producing an annoying vibration sound. Can anyone suggest how to get rid of it? - I was thinking of putting a thin layer of silicone sealant right under the grill covers. Any other proven ideas?

how about a gasket?

Do you mean a custom gasket cut out of a thin rubber sheet? Or you know of a simpler way of making one?

Gasket could be cork, rubber, vinyl, something compliant. Or tack it down with RTV or some other sort of sealant.

blue tack would be a good reversible solution to hold the grill down

A short update: problem solved. I bought a 1/16'' thick self-adhesive rubber neoprene sheet on eBay. Cut strips of 5-6mm width and variable length and put them on the horizontal dashboard surface, also cut narrower (3mm) pieces and put them on the vertical surfaces of the dashboard, where the grill clips go in. Now the grilles sit very tight with no play whatsoever, and there is no nagging vibration even at high volumes with a lot of bass.
