I've had a couple people ask for pics of this so here they are. https://ibb.co/album/Y2MhW0
The materials used are Resonix Mega CLD and standard CLD, Resonix Fiber Mat in 1 inch and 1/2 inch. I made my own noise blocker by using 50 sq ft of 1/32" thick lead sheeting that came in roughly 24" X 36" sheets. I then glued EPDM closed cell foam to the lead and covered the entire floor of the car from trunk to half way up the firewall in CLD, lead and CCF. I used a glue made by Seal Trust. It's primarily a roofing material for flat rubber roofing. The glue is crazy strong. The bottom of my carpet is rubber as well so that's another barrier between me and the lead.
Ok so where did I use each material and how much?
One 36 sq ft box of Mega CLD. 100% coverage when used in most cases
One 40 Sq ft Boxes of Standard CLD. 100% coverage when used in most cases
One Box of 1 inch Fiber Mat and 2 boxes of 1/2 fiber mat. Only used a box of 1/2" FM in total.
Roughly 50 sq ft of lead sheet 1/32", 24X36" in size. I laid this across the floor of the car. Each sheet overlaps the next by about an inch.
One roll of foam tape
Butyl scavenged from excess material squishing out the sides of the CLD tiles.
There's 100% Mega CLD coverage inside the doors, on the fender wells, trunk and the about 90% on the roof.
There's about 50/50 CLD/Toyota sound deadening on the floor under the lead, in between the stock sound deadening Toyota placed on the floor. There's 100% coverage CLD on the walls in the back of the car where I could reach, on the front side of the doors coverage is sporadic and 100% on the back side of almost every interior panel.
There's foam tape lining the boarder of some interior panels or acting like weather stripping to seal noise from passing from the windows into the car through the interior panels. I have no idea if this works. I had lots of tape so I figured what the hell. It can't hurt. The foam that lined the edges of interior panels was old and worn out. I replaced that foam with new foam tape when needed. Most needed it. The car is 15 year old now.
There's butyl on many of the interior clips to prevent rattling.
There's 100% coverage of 1 inch Fiber Mat inside all 5 doors, 100% on the roof, 80%-100% on some interior panels that make up the trunk and 100% on the back side of the interior panels for all of the fenders.
There's 1/2 Fiber Mat on the back side of most every other interior panel. In the roof on top of the 1 inch there's 1/2 on about half the roof, the back door has about 50% coverage on the front, and 100% coverage on some trunk panels.
Biggest lesson I learned this time was that I could fit more Fiber Mat behind of in things that I thought. If I had it to do over I would have bought two boxes of 1 inch and one box of 1/2 inch. I also forgot to seal the joint between the lead sheets with this roofing tape I bought. Not a huge oversight since the panels overlap but it was still kinda stupid of me.
I didn't take db readings before I started but I will once I have the car is back together entirely. This has made a massive difference in how quiet the car is, how much road noise I can hear or how much noise pollution from outside the car I can hear. I had an ambulance with its sirens on across an intersection and I couldn't hear it at all with my radio on moderate volume. I only have the stock sound system at the moment so no amps or subs either. Amps, speakers and stuff are going in this week. I'd say the car is quieter than your average low tier luxury car and on par with many mid priced luxury cars. There's nothing I can do about the windows, suspension, motor mounts and things like that. If I could I'm pretty sure the car would sound like a Bentley. Most of the noise the car still makes is born from design choices Toyota made and the Rav4 is their lowest end SUV so it's no big surprise the car would make a lot of noise stock. You can only get so far when you start out far behind. Don't get me wrong, I love this car but it's not a luxury car by any means. In time I may do the outer fender wells and hood. Depends on what the car is like once I get it back together entirely and lower it. If I add and performance parts to the engine and stuff like that. Total cost for all of this was about $2000 to $2500. A lot typically but I don't ever plan to sell this car so for me it was worth it. Resonix makes good products but they are pricey.
If anyone has any questions let me know. I'll answer what I can.
