Sound Deadening and Stereo Install


citka

Recommended Posts

This week marks the beginning of a complete stereo system install preceded by a sound deadening treatment to the entire car.

Stereo will be as follows:

Pioneer AVIC-Z120BT

Focal 165 KRX2 speakers in front doors

Focal 6.5 coaxial in rear doors

Alpine PDX150.4 amplifier driving the Doors

Alpine PDX100.4 bridged for sub woofers

2 JBL 8W1 8" subs in custom fiberglass enclosures in the cargo area

Sirius Satellite

JDM Double DIN faceplate

Sound Deadening treatment materials are supplied by Don at Sound Deadener Showdown. Big thanks to him for the guidance in this project. I've never done it before.

While I was in that deep, I decided to pull the dash and fix the rattle. It was much easier than I had expected. Plus it gave me the chance to reroute the wires for the PLX Wideband and my BFM Cable. I've got them tied into two USB ports I installed in the armrest in an earlier project.

 

 

Pictures to follow, but here is a teaser:

Well, the Sound deadening is in all but three of the door as of this evening. Here are pictures of the progress:

 

For reference, here is a stock rear door with the door panel removed:

The first step after stripping the interior is to apply CLD tiles to all surfaces:

Next comes the Closed Cell Foam followed by a layer of Mass Loaded Vinyl on top:

The Door panels are the hardest. You have to get the MLV and the CCF in them and still be able to attach the panels back to the door. Don at SoundDeadenerShowdown suggests hanging them on the door then applying panels, but after about 12 hours of working on one door, I decided I'd put the material in the panel itself and then attach it to the door instead. I simply couldn't make it work the other way:

Here is the interior with all the material on the floors:

I couldn't get the panels back on the door with the stock panel clips, so I had to buy extended ones. It will work out well because I have to have a 1" spacer for my front door speakers anyway to clear the windown when it goes down:

Time to start to reassemble the interior to get ready for the stereo install (which all the wires are run under the carpet, but on top of the MLV. I have to put all this back in:

Rear Door speaker in just prior to reinstalling the panel:

More to come as the panels go on and the stereo install starts...

Wow, I can't wait to see more pics! I'd love to have the time to tackle a sound deadening project.

If anyone wants any specific pictures of the torn down interior while I'm in this deep, let me know. I'm happy to do whaat I can.

 

It's best just to take a bunch while you can and post them so others in the future can look back and learn instead of us requesting them.

 

Looking forward to seeing how this goes!

The teardown of the interior was much simpler than I anticipated with the vacation pix. It's tedious and time consuming, but totally doable with a 10mm socket, 8mm socket, stubby #2 Phillips, regular #2 Phillips, flashlight and beer.

How hard was the fix of the dash rattle? It has gotten worse lately...

 

Some have said that it can be fixed by dremeling the bolt hole in the side of the drivers side panel and then bolting it up tighter...?

 

I assume this is a temp. fix and the best way is to remove the dash and reinstall...?

Interior is still how it looks in the picture, so I haven't done the fix yet. However based on what I'm seeing, I don't see how the dremeling method would be anything more than a temp fix, and a iffy one at that. I think the only way to do it effectively is to pull the dash and do it as prescribed. The temp fix may work here and there on some cars depending on the situation. I know some have reported it on the driver’s side, some on the pass side. Personally, mine is on the pass side.The sound deadening is heavy.

 

 

I'll have about 170 lbs more in the car when all said and done I think. That means I have to get a bigger turbo to make up for it!!

Some dash rattles are from the end of the dash where it butts up against the door, but the more annoying one is in front of the dash below the windshield.

 

If I recall correctly, there is a plastic cup clipped into the firewall and the dash clips into that cup. The cup rattles around. The only way to really fix it is to remove the dash and use some padding around the cup.

I'm going to pull the plastic cup and blow it full of Silicone then reinstall the clip. Then the clip will have RTV in it when I reinstall the dash.

 

A thin bead of silicone around the cup where it meets the firewall might be a good idea too.

I love every pair of Focal speakers I have ever installed! They are great for efficiency as well as freq. response....

 

I will say that horns sound a bit better but they take up far too much space for our mid-sized cars...

A buddy still has a bunch of matting from his install...perhaps I should do the doors and firewall....?

 

Maybe the rear hatch on the wagon? Trying to get the best benefit for the material since I won't have a ton of material and budget is small for this type of mod....

Having not done things separately...I have no frame of reference. However based on what I saw from blowing the entire interior out of the car, I'd susped that the spare tire well is a big contributor to the noise you get on the inside of a wagon too. It might be worth some attention. I can say that the one door that i have completed with the entire treatment sounds WAY WAY better when you close it.
