i need vibration reduction help

orangeneon05 · Post by **orangeneon05** » Sun Jan 03, 2010 2:14 am

ok so i installed two 12" woofers into my 05 neon's trunk and the back dash (the cover that is over the rear speakers) rattles and make an annoying chatter when the subs hit. does anyone know how to take that dash out or how to make it better secured and more vibration reductive.

Well, by no means do you want to pull it out. That's the main support to keep your quarter panels from sucking in...

You could try covering it with some rubber undercoating, or possibly some dynamat.

I learned that keeping the child seatbelt covers helped minimize that noise as well.

Or you could just turn down the stereo. Or, hell, turn it UP so you can't hear rattles.

i already took out the covers for the child restraint because of my normal stereo made them rattle. do you know how to take that plastic and carpet off so i can put dynomat under it so it would look stock and not messed up. i have a haynes manual and it doesnt show how to take that off.

Pretty sure there's a how-to in the how-to section here. If not, then sorry, no clue.

You could do it from the trunk without having to remove the carpet, however.

really how would that work i think the movement is on the inside of the car and not in the trunk

If the dynamat is on the other side it should stop the piece from moving, which would stop whatever is on top of it from vibrating.

At least it seems that way to me.

ok i got the idea its like sound proofing around the box and making it like a second box the whole trunk. thanks for the idea ill look into it and if anymore ideas let me know

At least yours is just that back part. All four of my door panels rattle too in addition to that back piece and I've got two 8" subs (free).

to answer your question, you can get to the back deck by removing the rear seats and seat backs (there's another quick way to do it, but i don't remember right now). Once you do that you can remove the rear deck carpet.

great stuff. you could get away with the regular version as well, but if you are going to do it once you may as well do it the best you can.

thats a little out of my price range. anything more afordable.

vibration damper is quite possibly the most important piece in a car audio install. i have spent as much, if not more, on this than any other single piece in my system. save up and get some good stuff and do it right the first time. if money is that tight you can get 40sqft of regular damplifier for $100 plus shipping.

thats not a bad price considering dynamat is pretty expensive IMO

keep in mind the damplifier is similar to dynamat xtreme but the pro version is much better. foil is over 60% thicker and 30% overall as well.

I used a 100sqft roll of Fatmat brand on my last audio install and covered the ENTIRE interior of a 93 Prelude. The Fatmat worked just as well as any Dynamat I've ever heard. Plus we got the roll for $100 on ebay.
