CHEAP DIY Sound Deadening

I'm sure we have all wanted to do sound deadening to our vehicles.

Until we go to the store and see 1 square meter for 100$ lol...

I've heard you can use carpet underlay and have respectable results, but i was concerned about the possibility of mold build up.

what im going to be trying to to use a very high quality underlay with mold resistance, and put tinfoil (applied with spray adhesive on one side) ill put it on one door panel and see how i like it, and if it makes a worthwhile difference or not. ill also try using vapor barrier plastic instead of tinfoil.

Ill try foil side out and foil side in, as well as foil with underlay on both sides.


if anyone else has any input it would be appreciated :D, ill be starting tomorrow. post my results when im done.

ill be starting off small and if i like the results ill do the whole truck :D

So I've finally done some of the soundproofing (4 doors and kick plate areas). and am quite pleased with the results.

i used this material from home depot, and for $50 (CAD tax included) for a 6x9 roll, i had enough to do the doors, and kick panels and still have half a roll left to finished the back hatch and other places.


I picked this one because it repels moisture and mold, insulates, and soundproofs, it is also very strong and tear resistant, but flexible.


First you want to remove your door panels


Next you want to clean your work surface well, remember our putting you door panel on it so you don't want to mangle it.


The easiest way I found to get the shape right is to unroll part of the material on the bench and place the door panel on it (face up), then using a sharp knife, trace out the panel. Also mark out were the handle is. (be careful not to nick your panel).

when your done, flip the panel, and lay your foam cutout on top, as for mounting I just pushed it over the "Christmas tree" clips, and under the lip. make sure you leave slack in the material around the middle for clearance.


after cutting out a hole for your speaker, and were the handle is, you just need to route the wire for the controls, and put the panel back on!

im going to keep using this stuff, and put it everywere.

It might not be as good as the Dynamat stuff, but it seems like it would help
 






For my sound project I've been using[ Quiet Coat and it works. Definitely cheaper than the regular sound deadeners. I've never used Dynamat or something like it so I don't know how it compares, it has good reviews though.
 






it has to help at least a little because i have a truck with absoultly no insulation or carpet underlay and its crazy loud, and a car with only carpet under lay and that helps it should also help to insulate the inside too
 












The factory grey underlay beneath the stock carpet and behind the plastic panels is responsible for a good bit of the sound deadening the Explorer has, so adding more would definitely work. Just be sure to use the right stuff, cheaper quality stuff for indoor carpeting might do okay, but won't be nearly as durable as the heavy duty kind for automotive use.

Most any kind of insulation can be used for a great deal of sound deadening, just stick it into the metal bodywork behind the panels and you'll reduce a ton of road noise from the wheels.

The cheapest budget sound deadener is probably spray-on or brush-on rubberized undercoasting. At a few bucks a can, it's hard to beat. Dupli-color also makes a truck bed coasting in a one-quart can, for around US $12-15. It's apparently not that great as a durable liner for truck beds, but is probably decent to coat metal panels with for sound deadening. The only drawback to the coatings is that they are a pain to deal with if you ever have to do bodywork where you sprayed them.
 






worked good for me :) in case anyone wanted to try it.

One problem with rubberized undercoating is that the odor after application lasts for days... and days...
 






This is a product I have used and it is low cost...

It's called Peel and Seal...It comes in a roll and you have a sticky side and a foil covered side to the inside of the truck.. I used it for the rear cargo and right rear sub area and will be using it inside the doors soon to cut down on road noise...And there is no odor that I can tell when it gets hot...
 












house carpet is a very good sound absorber.. and it's cheap (often free) get some old carpet, the thicker and denser the better.. glue it inside you're doors and such, i bet it would work quite well.
 












i was really happy with the results, one of my friends has the exact same truck as me and said it was a lot quieter.
 






NO...this is NOT cheap sound deadening. But, it is the right way, and the most effective. Any other way, you are taking all kinds of chances. Peal & Seal will slide down your door, in summer heat....period! DO NOT use it! I did, and learned the hard way...after I was told this very thing by someone else, and I didn't listen, either. I would rather mow a few lawns, in the summer, and save my money to pay for the good stuff, than go the cheap route.

This is Luxury Liner Pro. Made by Second Skin Audio. It was laid down on top of a layer of Damplifier Pro. Made a HUUUGGGEE difference. BUUUTT, you have to make sure to cut it to fit; tape every seam with Gorrilla Tape. And for those with third row climate control; you will have a small "pit" where the A/C lines come in from under the body. This area will be a large source for noise leaking through, after you use the LLP.

With all sound dampening, you should treat it like a boat. If water can leak in, then sound can leak in! The fewer gaps, cracks, and holes, the more quiet it will be.

This is the Damplifier Pro. It must be laid down on large, flat, metal surfaces, under the LLP.
 






and i just cut up some reflective sunvisors. worked pretty well, and doesnt make any noise from the speakers in the doors
 






I used Peal and Seal on one of the Escorts I had before... When I had the interior out so I could replace it with Miata interior, it sat in the sun for a couple days in 100+ degree weather with nothing holding up the Peal and Seal but itself, and it worked out just fine. None of it came off. It is an asphalt product though.


By the way. This is a 2 year old thread.

...and days :D

Until a hot day comes along....

Then the odor comes back again and lasts for days.... and days...
 






Best for the money is Audio Technix. Cheap, and works extremely well.
 






There is also Lizard Skin.....
