hatch vibes ughhhhh

[flaveo5]

messing with my sub tonight and set the gain on my amp to 70-80% it can hit hard and loud but the truck doesnt seem to be able to take it.. i mean everything is making a racket in the back of the car sounds like the plastic is just vibrating bad tinny noises etc.. i guess its dynomat time...

think it would make any diff if the sub was firing back vs up?
anyone with a hatch knows there aint much sound deadening in there its just basiclly bare metal and some plastic bits...

hmmmmmm

[ontarian_frog]

unfortunately the wiper mechanism is in there. plus the access hole isn't too big, it would be tough to dynomat... First things first, the only thing I did was put double sided tape on the bottom of the license plate to stop it from rattling. So far so good, but I only have a 300W sealed system.

yeah already have the plate done
at around 500rms i dont have too many issues
at 700-800 rms is when it starts to really vibrate bad

To effectively get rid of all of the vibrations in the car you need to use a combination of deadeners mat/liquid/foams, but it is possible to limit the amount of vibration surfaces.

wear ear muffs they're cheaper

Now, a fact to point out - the thickness does not determine the dampening properties of the deadener. The material composition and how well it reflects the sound is what makes the difference. You are unable to absorb the sound waves with any decent amount of deadener, you would need layers multiple feet thick to absorb the sound waves. Instead, you have to deflect them, and different materials do that better than others.

The difference between products such as Raamat, and fatmat, and SS, is not the thickness. It's the material type, the composition, as to how well they will work. SS is more expensive, but it does the job a lot better. If you don't care about a really nice job, but want a decent deadening job, just enough to help some, then the others are cheaper. If you want nice results, and the same results from all products, the SS will be cheaper to attain those results. That goes for the materials on sds, also.

If you don't care about having a great job done, and really want to constrict the budget, go with the cheaper stuff. If you want that nice job, instead of trying to make the cheaper stuff work, you'll need to bump the budget up and get better materials. And the amount of layers won't matter. Shouldn't need any more than two, really, just even one. It's for the deflection of sound, not the absorption, and the thickness does not matter nearly as much for that.

if you think 700 watts causes alot of rattles, try 2500 or 5000 lol, ive actually broke a couple things in my car with my system.

[thehunterooo]

lol my car rattles like crazy

[flaveo5]

i guess where these are cheap car theres no real happy medium lol
i never had these types of rattles in my protege5 when i had it
its not so much as a rattle either as it is like the hatch makes a vibration or the plastic 3rd brake light and rear plastic bits

[thehunterooo]

lol ive seen nice cars rattle, they just need big speakers :P :P :P

i dont what rattles besides my mirrors, and maybe some piece of plastic in the back
