Yaris Sedan Deadening and Sound system upgrade

[derickveliz2]

Ok I've spend a couple of hours every day since last Saturday.

These pictures show how I end up applying CLD Tiles to the Trunk, Quarter Panels and Rear Deck, I did put some extra RaamMat in the corners and or blocking openings in the frame.

It's amazing how solid everything feels now. (still the noise penetrates)

Then I put 1/8 CCF (foam) on the floor of the Trunk and Rear Deck, 1/4 CCF under the rear seat and wheel wells.

On top of that goes the MLV (vinyl 1lb/sf), I did put it on the floor of the Trunk under the spare wheel tire, under the Rear Seat and on one wheel well (right side) I haven't seal (with HH-66 Vinyl Cement) the overlappings between MLV layers.

Noise level is getting close to 5, I can tell the road noise from the quarter panels, rear bumper, and left wheel left. (there are no back seats)

For the air valve I end up gluing to the quarter panel cover a 6 x 14 piece of 1/4 CCF and worked great, I hear no road noise coming from that source; I can flip from circ. air and fresh air and I can't tell the difference in noise like I did before.

I also installed the main (-) ground, there was a big nut like the ones that hold the frame of the backseat. I started to run RCA cables and also installed the 3 1/2 speaker on the rear deck.

Only using the OEM radio with OEM front speakers at front and these tiny 3 1/2 speakers, I can tell that I feel the difference already, feels like my OEM stereo got an upgrade (we are not there yet)

I'm thinking on putting a DashMat like Sqcomp! I got some samples and this is what it looks like, I was thinking on putting a thin layer of 1/8 CCF to help absorb the noise from the windshield.

More soon...
