Exterior Panel Rattling

[Jake007g]

So basically, I have 2x 900w subwoofers in the boot of my MK2 PH2 2004 Clio (Dynamique). They sound brilliant from the inside, but whenever I turn them up past around half volume, the exterior panels vibrate violently!

What would be the best and most cost effective way to go around fixing, or reducing this problem?

I've heard of sound dampening materials like Dynamat for instance, but this seems rather expensive. Are there not any easy materials to get hold of, that can sort the problem out?

Thanks in advance!

Take subs out, problem vanishes!

the bump strips on the side of car vibrate like mad.
apply duct tape from the inside

Nice one

Sounds like that might work, so I may have to give it a try. Thanks!
