After i installed my Pioneers, when it hits a bass note, the doors rattle like a mother. For those of you who used it, where did you put it?

 

I did the entire surface of my doors between the door panels and the actual inside door surface. Dynamat is expensive so I used some Hi Temp Mastic from McMaster Carr. I don't know if it's as good as Dynamat, but I don't have any rattles at all.

Hey man

I'm not sure if it's the plastic panels or the actual door that's to blame. Maybe i'll just Dynamat the crap out of it and see what happens. The back passenger door is the worst. I'll just do that one first and see what happens.

 

and you might want to visit partsexpress.com and purchase a couple cans of the Cascade brand aerosol sound deadener. Spray the heck out of the inside of your doors, in addition to using dynamat. give the product plenty of time to dry, and i learned the hard way that it is infinitely better to apply several thin coats than trying to plaster one thick one. don't forget to re-open any plugged drain holes in the bottom of the door. toothpick works just fine. my doors are extremely "dead".

 

A lot of buzzes are connectors and other hard parts beating against each other. Ford uses a foamed adhesive weather seal between the door skin and the metal frame. If this is gone you may get more 'play' in the wiring and things might vibrate. Get some duct tape and tape everything down, then apply the vibration damping sheets directly to large areas of the sheet metal. Be sure to clean the area first with rubbing alcohol.

 

when i took out the stock speakers and put in the pioneers i took electrical tape and taped all the excess wire down so it wouldn't rattle around. I'm pretty sure it's that back passenger door that is rattling worst. I think it accounts for about 80% of the noise. I'll work on it when i get a chance and try the suggestions.

thanks guys.

 

screw dynamat there too expensive..
try www.canadiancaraudio.com/
they have a sound deadner called b-quite extream and it is very good(I use it)
+ cause it is canadain you will get a hell of a deal!!!!

tell them ICON sent ya.
+ dynamat smells like petrolem where as the B-quite doesen't smell after about 1/2 hour(doesen't smell at all really)
just when you stick it to your face..

trust me you will love it and you don't need heat.

 

link doesen't work you will have to type it in.

sorry..
but worth the look.

 

fixed it.

 

I would stay away from B-Quiet if you live in a hot climate...It does work, but it also melts very easily in the hot summer heat. I've seen it, and I've helped a friend of mine scrape it out of the bottom of his doors when it melted.
I live in VA, and it melted here...I'd hate to see it Arizona or Florida...any place where it gets even hotter. I dynamatted the heck out of my truck with several different types of Dynamat, and the reason it's the most used is because it's the best. You get what you pay for.
