Subwoofer boot/panel rattle

[tje]

So this weekend I decide the single ten inch sub wasn't powerful enough or loud enough.

Went and got myself twin 12" subs with a mono block amp to match.

400rms on each, peak of 1200.

Sadly once you start to crank it up the bootlid and, all thought my 100% sure, the rear quarter panels make a horrific rattle.

I've given it a google. Some people swear by dynomat, others say it's a waste of money. Others suggest insulation or the expanding foam stuff. One even said cut up socks and stick them in gaps and places.

Has anyone got any tips or tricks on how to stop/reduce this?

Thanks.

in the pasted when my brother was using a couple kilo watts he used some bitumen cut in triangles glued on the panels no that this helped as his whole car was moving by air
