How to Soundproof Car Doors with Mass Loaded Vinyl

1. Prepare Your Tools

Note that you won’t be needing all of the tools depending on if you want to install mass loaded vinyl for your car door, trunk, floor, or all of the above. You probably also have most of the items already.

2. Remove Door Panel

In soundproofing the door of your car with MLV, the objective is to seal the cavities in your door and you would need to take out the door panel first.

Be careful not to damage the wires or other forms of connection behind by disconnecting them before completely pulling then panel away.

After taking out the panel, you would be faced with the door insulation and vapor barrier. 

At this point, take off the speakers, then the screws and clips that are holding the vapor barrier in place. Take pictures before you take them down for reference. 

3. Prepare MLV and Cut It Out

With the barrier out of the way, you would be at the inner door frame where the installation would take place.

The cables would be unclipped so you also need to take pictures for reference just in case.

By unclipping the cables, the door frame would be clear and ready for the installation. Take note that when installing MLV, you would need to make provisions for all the holes and slits on the door for the screws, clips, and cables. 

Place a clear bag over the door frame and hold it in place with the clips you removed earlier. Then with a marker, outline the shape of the door so you can know what shape to cut on your MLV sheet.

Once done, transfer the clear bag to cardboard and cut out the cardboard according to the markings you made. This will make it easier to cut out your mass loaded vinyl. 

Then roll out your sheet of MLV and cut according to the cardboard. Replicate the cardboard markings on the MLV too and try it on the door to ensure it fits. 

4. Prepare Surface for Mass Loaded Vinyl Installation

Before installation, clean the surface thoroughly using alcohol and a piece of soft cloth. It’s necessary for maximum adhesion.

The inner part of the frame also needs to be soundproofed, so cut out a large piece of MLV for that purpose.

5. Install MLV to your Automotive and Finish

After this, install MLV over the inner and outer door frame. Ensure you pass the cables through the required holes and slits. Cover the area around the speaker properly too. Once you are ready to make it permanent, use green glue as an adhesive to hold the MLV in place and use the roller to smoothen it out.

How to Soundproof Your Car Trunk and Floor with MLV

1. Prepare The Area

For the trunk and floor of your car, you would also need to take everything out. Remove the car seats and then the carpet by unscrewing.

To ensure maximum adhesion, clean the metal surface with a soft piece of cloth dipped in alcohol. 

2. Measure and Cut

Measure the surface you need to cover, so you can have a rough idea of how much MLV you would need.

You won’t cover the whole interior with a large piece of MLV, but rather you would do it piece by piece.

So measure out the flat surfaces that you would cover, and then cut out the dimensions on your MLV sheet. 

The surfaces won’t be in straight lines all the time, so after cutting out the material, place it on the surface you want to cover and then mark out the required shape on the cut mass loaded vinyl piece.

Cut out the required shape with your utility knife and mark out areas where there are bolts so you can make room for them using the punch tool.

Note that the most important parts to soundproof are the flat surfaces rather than curved surfaces. 

3. Install the MLV to Car Trunk And Floor

Once you have gotten the shape for a particular surface, apply green glue and then stick it. Tape the seams with aluminum tape to seal any gaps through which noise could travel and then with a roller, apply pressure on the MLV to stick it better and flatten it for a great finish.
