Sound dampning, when is enough too much?

[Mach 1]

Ok, I went nuts with it, I tore the interior just about all the way out, some 20+ plastic panels. I found some metal shelves inside the C pillars to cover, I went under the dash, I went inside the outer dash panels, I even used some 3/8" poly urethane foam under the floor carpet(great for the feet). The front doors were a little tricky with the black plastic divider, be careful as the 2 torx bolts free the window from the mechanism, I scribed/marked mine, so I didn't have to reset up and align window.

I went inside the engine compartment did the hood all the way to the wipers, I did firewall, the frame members, the front fenders-all the way up to the doors. I want to do the rear fenders as they are very tinny. But I have to wait till I get it up on my lift.

I put a lot of emphasis on the front bed bulkhead, as it shares with the interior rear wall. Mine already had the spray in bedliner, which works well. The electric black boxes on mine rattle like the Dickenson so I addressed them, the amp bracket needed help as well, any metal 'ears' hanging in the air got addressed because of resonance.

The next mod would be the wheel wells, I get a lot of tire noise/road noise, I plan to use a heavy material and spray it on the fabric 'wheel wells'.

I used several boxes of kilmat, 1-38ft, 2-18ft, 3/8"foam, spray undercoat.
Sound absorbing closed cell foam.

Living in Texas heat insulation is good as well. My AC works well, stereo sounds alot better(upgrade speakers while in there). Mass behind speakers is worth doing.

My underseat storage, after I applied mass, I installed closed cell sound absorbing foam, lined the storage areas which prevents rattling of stored goods. Also alot of people will add mass but forget to add the sound absorbing material to prevent sound waves reflextion. With the mass metal, you get a lot of bounce and deflection of the sound waves, these need to be captured and converted.

Hope this helps..

But you must tell us now, how does it feel my dude?

How much weight did you add to the truck?

I usually do all my vehicles since 2000 f250 7.3, close to 10 vehicles, so its just SOP, standard operation procedure. Living in Texas, u can fry an egg on dashboard and I have seen right at 200° f here(dashboard temp). There's 3 main advantages to sound deadning/proofing for me..of course reduction of noise/unwanted levels, increased insulation value of vehicle AC/heat works and maintains Temps inside vehicle(along with every window tinted), takes a mediocre stereo and transforms it into a semi decent system.


To answer your question, its frigging makes the vehicle rock!! Totally different vehicle. Least expensive mod for the biggest return. I don't think I could stand for not having it done...

How do they say it?

Hey I’m in Llano waiting on my Maverick . Did you take any pics or do have any helpful tips on the sound deadening ? How long to accomplish?

Llano, I was just there today, cruising Kingsland, there are all kinds of Incomplete interior disassembling on you tube. I had to watch several and still couldn't piece it all together. I have done several ford interiors and have the tools. I just jumped right in. I haven't taken the time to learn how to pics. If you want I could maybe cruise by and give you some pointers, there are some good driving techniques to learn as well.

There are plenty of posts about stereo upgrade and soundproofing here.

Thats why I posted this thread, how much is enough, there's plenty of real estate on the Mav. Depending what you want out of your Mav. From what you put into it, the supplies are fairly inexpensive.

I really recommend the closed cell insulation on top of the mass. I really believe in attacking the sound arena, before adding any kind of power. Its remarkable how much you can get out of the listening space. Cancel out the stray sound vectors that are reverberating and reflecting off the flat surfaces. Catch them and dispose of them before they do their harm.

Cool! So, where are the pics?

Appreciate the input. Your passion for this is going to make me more seriously consider it when I do my stereo upgrades.

The mass dampning adds weight..no doubt, plus upgraded speakers=50lbs. Whats important is i still pull down 53mpg, 700mpt, 2nd in a row.

I am hyped about my Mav, its a keeper, I kept my F150 eco 3.5, which I usually get 25mpg, just got 27 on a road trip to score the Mav.

I guess I need to learn how to post pics..wife/friends said I was nuts tearing into the Mav that deep, but I have to look it over for potential problems and mods.

I don't have a problem posting what I see hear do..
