Alternative to Dynamat?

I have 2 Fosgate P3 10's on a 1500 watt RF Punch amp. I have a really bad rattle in my trunk and I was wondering if there was an alternative to Dynamat. It's so expensive and a pain to install. I heard something about carpet insulation?xx2Low4Earsxx

this is john iam new whats up .i use this stuff that is used to stop leaks in aluminum buildings i dont know the name but find a local commercial roofing supplies company its about 30 bucks for a say  a 12inchx10ft rolls they also sell different lengths it works great it has a metaltin foil and adheseve backing once you put it on its on...john ortega

Cool I'll try that. Do you think they would have it at a normal building supply store? Like Lowe's or something to that affect?xx2Low4Earsxx

i dont know .also i have tried the material you lay on a roof before puting new shingles on you need spray adhesive and a heat gunjohn ortega

Ok I'll try that. Thanks man. What kind of system do you have?xx2Low4Earsxx

i believe its called ice/water membrane they put it down under the roofing shingles home depot usually carries it if you search the web or ebay im sure u can find other alternative to dynamat also

you could also go with Second skin's overkill mat. It's cheaper, thicker and  a bit hardier then dynamat and peel n' stick. I think a 160sqft is around\4400-500. worked pretty good on some of the large trucks that I've worked on when we really need to mask over a diesel engine and mudders.
