How much sound deadening and proofing material do I need?

This thread might be worth a read also, lots of good info here.

I think that's the thread from which I got the idea. Someone in there mentioned sandwiching the MLV between two sheets of 1/16" neoprene which doubled as CCF and a decoupler.

 

You can take out the headliner.
Everything has to be stripped, the steering wheel in the lowest pushed in setting and removal of the rear view mirror to help with the limited space.
Angle it where the front is towards the front passenger side, and the rear is to the driver's rear door.
The hardest part was trying to manuever it over the transmission section.

 

Two boxes of the 80mil (so 72sq ft) is more than enough if you're going to do everything but the headliner. I was able to do:

• Entire floor with a double thickness in a few spots
• Back wall of the cab
• All 4 doors which includes doing the backsides of the plastic door too and a few double spots
• The top of the wheel wells in the engine compartment
• The honeycomb spots on the inner hood

And I still have some left.

It does make a difference although I don't have a quantifiable # to give you with regards to decibels.

 

I could be wrong, but I thought the 80 mil was not rated for placement in the engine bay and could lead to a sticky mess.

 

Ill keep an eye on it.

 

I’m getting ready to tackle this, did anyone break any tabs/clips or anything that I should have on hand before attempting?

 

If it's headliner, not done yet, but on the list.

If you're doing doors, There are clips on the doors , small white ones (3x) holding the vertical trim pieces. These little clips stay stuck in the door when you take the trim off, and if you try to re-install the vertical parts they will push the clips through their recess/holes and you will lose them. Pop the clips out after you remove the trim and install them in the door trim piece prior to re-installing.

 

How far are you planning to sound deaden?

Remove the negative terminal from the battery.
If you want to make cutting holes easy, use one of those leather punchout tools. Perfect holes and a professional look.

Doors: Sail piece has three clips the do not initially come out together with the trim piece. BEFORE reinstalling, be sure to take those 3 white clips and install it on the sail trim itself.

Careful not to bend the door lock and release wire levers. Just pop them out when you pull out the door card.

Best to use OEM Audio +'s speaker install video for the doors.


Rear Wall: Cargo trims just pop off. Some trucks have a hanging jute padding or a MLV hybrid.

Floor: Got to remove all the seats. Careful with the front seats when removing and reinstalling, the rails can easily damage your paint/car. Two or more people is best. Carpet comes out as one piece, might need to fold in the center to get out of the truck.

There is a cotton/fabric jute padding that can only be removed by one, cutting it at key areas around the transmission tunnel or hardmode two, removing all the things in top of the transmission tunnel.

Personally, I just worked around it, much harder though.

Headliner: Got to remove all the seats. Remove overhead console, and dome lights. Remove rear grabhandles, hangers and front vanity mirrors. Remove A and B pillars. There is a wire taped to the headliner on the driver's side A pillar.

The headliner should drop a little, it is being held up by LOTS of wires hotglued to the headliner. Slowly release the wires from the glue. Careful the headline can crease and leave a permanent crease line.

Getting the headliner out is very tricky. Got push in the steering wheel into the lowest setting possible to maximze space. Then angle it on its side, front at passengers door and rear towards the driver's rear door.

Getting it in and out is a major pain, so I instead worked around it.

 

This!

 

Thank you so much for this! I’m going to try and do the whole truck so this helps so much! I wouldn’t even attempt it if it wasn’t for the help from this forum

 

Check out youtube - Jesse Rizzo does a pretty detailed video (two vids actually) on doing the floors and doors. Very helpful, it brought my confidence level way up before and during my install.
