at car shows people have like 2 subs and an amp and their car points but dosent rattle or anything.. i have 2 mtx subs..12', a pioneer ddeck deh-p6600, and a sony explode 1000w amp.. and my back bumper seems to shake same with my rear dash (a bit) and it dosent pound like theirs,, wast wrong>

Because they have money invested. Money in sound deadening, Money in install, and all important, Money in gear.

Like said, they have A LOT of money and time invested in their stereos. Sound deadening, concrete (seriously), etc etc.

I have quite a bit of rattle. No sound deadener. But My truck still pounds. So heres what its most likely is, THE INSTALL. Its all in the istall

[jay99]

the install of the wires? the deck? the amp? or where my subs are? cause my subs are just in a box facing my trunk..

[supraman1379]

the box size, where the subs are facing. ( which I think you have them in a good spot facing back cuz mine was louder that way too), But mainly the box size and stuff like that

[jay99]

my box is appearantly custom for my subs

[supraman1379]

You really only see concrete in the extreme cars and every now and again in super street vehicles....

All of that is critical to your success in the lanes.

nope whats that [polyfill] ?

Polyfill is the trade marked name for the product a company sells for car audio installations. Basically it is polyester fibers that are placed inside of a box. They vibrate sympathetically with the bass and transform some of the acoustical energy into heat. This has the indirect effect of making the sub act as though it is in a bigger box. Generic PolyFill can be found at your local super walmart as pillow stuffing and it will cost 2 dollars for about 10 pounds of it.

The Real Polyfill is identicle in nature and will cost you 15 bux or so for 1 pound!

I know some SQ guys that have used thin layers on concrete and concrete like substances on doors and floors

Who does? It would be quite useless in a thin layer on the door becaus the stuff cracks incredibly easily when in a thin layer. Hell it cracks incredibly easily in a thick layer (4" +) too...lol Structural engineers joke about concrete all the time. It's hard, it's grey, and it cracks.

Maybe they were telling you fiberglass resin mixed with sand in a thin layer over the door?
