Sound Deadening in The Z

I though I would share a little bit of the non-performance side of my truck. This project has been going on for quite some time now and I am still definitely not done...

Here goes to the start of deadening my 02 Z71. Lots of deadening going in.

155 Sq ft. Raammat
5 or 6 Yards Ensolite
5 gallons and 1 quart of Spectrum

GM's way of trying to stop you from removing the rear bolts on the front seats an 11mm 12 point did the trick. Also the front nuts on the front seat are removable with 15mm 12 point.

When I saw this clip for the first time I thought "I'll come at you like a spider monkey!"

The rear light needs to be removed before dropping the headliner to disconnect the light

My Friend Trey putting a second layer over the rear cab vent

The amount of time put into this is something fierce but it really does help the overall sound quality of the vehicle. If you guys have any questions post up!

your friend is cute.:naughty:

Did similar to my truck just now quite as involved. When did you start and when you projected to be finished?

Started early March this year and projected to get done by the end of this year. With the heat this project really took a back burner. Most the work I have to do is to finish glassing the large holes in the front door then deaden them.

oh yeah, I still have 5 gallons of spectrum to apply, which means the truck has to come apart again sometime. I plan on applying spectrum to every piece that I can and coating the floor, back wall, etc.

Then I have to install the ensolite as well.

Damn... didn't realize I still have soo much to do

Wow you really went all out.:ugh2:

Can You Tell The Difference.. I Mean Like Is It Quieter ?

damn that does look like alot of work. But I bet it will pay off!

When I had stock exhaust I tried to start the truck while it was running when my window was rolled down.....

You definitely can tell the difference when you do the doors really well and add in a pair of amped speakers and a sub. When you seal the doors and put them in a IB situation they can extend a lot lower, and mid range response is greatly improved. With the sub you eliminate a lot of cancellation caused by rattling panels and effectively make it louder.

I have yet to install the ensolite, which should eliminate road noise

You have been talking with //M5 too much. :laugh:

:P no doubt. Guy has never steered me wrong though. Really the whole SSA Forum has brought my listening standards way up.

Never got into it that deep, I would rather go fast instead.:tvhaha:

So Around how much u spend?

i did the same thing to my truck, not that detailed though. i never took the headliner out. i used bri roofing material on the floor, its about 1/4 inch thick, and the same kinda stick on aluminum backed rubber for the walls, i got a 100 foot roll for 15.00 and the thick stuff i had left over from a job. it looks like you got the aluminum roof stuff too? it never comes off thats for sure.

as far as sound i had several variations of subs in the rear before i found some that wouldnt fry from all the power i had in there. i think i ended up with a dual 12" subs in a bandpass box which was too big but man it was powerful. i think it was at least 2000 watts total system and at that level it was perfectly clear as far as distortion. as far as outside noise it was really amazing, at full volume levels it sounded like a stock stereo jamming loud outside. the low freq bass signal was completely kept in.

i never wanted to be annoying to other drivers or show off but i wanted to have great sound quality reproduction at a level where i wouldnt want it any louder, at the time with pantera, metallica, sepultra and all the other music i was into i liked it really loud.


BTW, your friend is a hottie:luv:

Did some digging around on prices. I got 5 Gallons of spectrum for $160 shipped (which was a great price). I got 1 quart for free ($10 Shipping). I think I got 2.5 Rolls of Raam Mat, Yards on Ensolite and 2 Adhesive cans (for the ensolite) for $375ish. So all in all about $550 in Deadening materials.

yeah if you go to a roofing supplier you would find the same materials, (labeled differently) for a really cheap price.

Its not the same, type of materials differs greatly...

Most definitely not the same material. The roofing that you are talking about is an asphalt based compound. Common problems with it are adhesion and smell in hot months. I used this on my 90 model silverado with good results though because I was being very cheap.

The Rammat is a Butyl based deadener. Adhesive properties with it are much better and it withstand much more heat. Unlike asphalt which is only a mass loading deadener butyl has viscoelestic properties which actually convert sound waves in to miniscule amounts of heat. This is in an addition to the mass loading qualities.

I have heard many people say that dollar for dollar butyl based deadeners are better than asphalt deadeners, and that they would rather use less Butyl based deadener over more asphalt based deadener because it will produce better results.

i did dynamat in my cc doors and backwall. made a big diff. have yet to tackle the floor and headliner. i give you props, lots of work.....

yeah i know they arent exactly the same but the difference really wasnt worth the $$ to me. the smell of the rubber went away after a few weeks and never came back. its been years now and no problems with any adhesion. I know the floor stuff i used is like 1/4" thick so that really made a difference.

i didnt do nearly as nice of job as you did and at one time i had 3 x 12" in it testing them and with the doors and windows shut you would never know it was more than a stock stereo. killed the bass almost completely outside the truck.
so it got the job done anyways. i cant wait to hear about the results from the job you did, gonna be like a casket i bet.

Great job. I did the same thing to my F350. My hands looked like I got into a fight with a weed wacker and LOST! Damn I've never been cut so many times in my life. Its worth it big time, I can now have a phone conversation and not have to yell over the tire noise.

Just kinda wondering....whats the difference between the stuff you used and dynamat?

dynamat is a crappy overpriced asphault based deadener.

The stuff he is using is a good wellpriced butyl based deadener.
