whats up everyone just need a little advise i got a 2003 civic coupe im currently running an alpine head unit with 2 6x9" JBL GTO speakers in the rear and 2 6.5" round kenwood speakers in the front i also have a single 15" round adiobahn sub that runs 1300 watts RMS powered by a Hifonics Brutus 1600 Watt RMS amp......i'm totally fine with how everything sounds so far.... while im inside the car its pretty loud sound is pretty clear and will be better when i amp the speakers this weekend....but when i get out of the car the ratling and vibrating sounds HORRIBLE...ive heard dynamat helps but have never heard the results for myself.....just wanted some advise on instalation price and any other products that may help me...
thanks for all your help
peace

 

Its not going to help as much as finding what ever is loose and tightening it down. Alot of times it the liscence plate cover and a nice peice of foam tape behind it normally fixes that.

 

thanks tightening sounds like what i need to do cuz i know its not the license plate......cuz i took it off and it sounds exactly the same......what are things i can tighten????

honestly dude....dont waste your money on dynamat. I just had a thread on this entitled "F*** You Dynamat" lol It sucks for how expensive it is and it only eliminates about 50% of rattles I even bought the extreme trunk kit......160 wasted dollars (110 cuz it was open box). Find some cheaper stuff like fatmatt or brown bread. You can get way more for way less....and i think that is the key to stopping trunk rattle....massive amounts of rubber sh*t in your trunk lol

 

use dynamat you get what you pay for..iv'e used it for years and have had nothing but good results.. prep your surface real well with a wax and grease remover and take your time when your putting it down. use a roller or the handle of a screwdriver to make sure it's bonded well to your surface. iv'e used other mats it the past and they sucked most of them wouldnt stick which is very key to stopping vibrations..

this is just my opinon with what iv'e found works well... i'm sure some people will have some things to say about it

 

i used a trunk kit on my car and it works awesome no rattling or nothing i bought mine from etronics.com very cheap here good luck

 

You have to make sure youtr trunk is nice and tight and check the weather stripping on the trunk.

Dynomat and all these other products can help but the first step is to make sure everything is buttoned up correctly first.

Then if you still have the rattles move onto things like dynomat and such.

I have personally never used dynomat but alos never realy had a really powerfull setup. I did have some rattles with my current setup and things like the licesnce plate and the trunk lock helped with the few rattles i had.

 

thank you all for all the help gonna check out the trunk and tighten whatever i can and then see what the deal is......bx_civic thanks for the advice also nice to see another BX native on the forum...what part of the bx you from?
