Ideas To Stop Board Rattling

Alright... i got aftermarket speakers (250watts) to replace my stock speakers and then a new head unit.

Ever since I got the new radio I get alot more vibration... my question is how can I get the "fuzzy board" where the speakers are (behind the back seat) to stop vibrating so much.

Thanks

I had the same problem with my old car. I had to cut port holes and put speaker covers over them. The readon I did this is because my subs in the trunk moved to much air and my trunk had a good air tight seal so I gave it breather holes. hope this helps?
