I was tracing a buzzing noise from the sub enclosure this afternoon. Thought I'd fried the sub or broken something in the enclosure on a speed bump or what not. I opened the boot to check, no noise. Closed the boot and the whole of the bootlid resonates. Everything is tight, seems like the sub has found the resonant frequency of an Astra boot.
Now I need to sound deaden the boot lid, but I want to do it as cheap as I can. Has anyone found a cheap source of sound deadening material?
