Work begins on the interior of my truck. What you see below left is almost $1,000 worth -------------------------- Below is the drivers door, with the panel removed.
of sound deadening, 125 sq.ft. of SecondSkin's "Damplifier Pro," 5 gals of "Firewall" -------------------------------- The Pioneer 3-way speaker on the right has been
used for both heat and noise reduction. I'll use it inside the cab. Plus 5 gals of "Spectrum" ------------------------- replaced by an Infinity 6810cs component set.
a noise and vibration coating I'll use outside the cab as an undercoating. The black stuff
on top of the Damp Pro is called "Overkill-Pro" According to SecondSkin "This vinyl based
filter not only dissipates airborne sound waves that are able to penetrate the layers below
it, but because of the rubber content it enhances vibration damping results." I have about
60 sq. ft. of it and I'll use it to cover the back wall, floor, firewall and wheelwells of the cab.



Here are the Infinity Reference 10" sub and amp, I have 2 of each, that will replace the current set up soon. My neighbor is building a box to house them now.


This is a close up of the openings in the drivers door with the speaker removed. The heavy tube running through the middle is a reinforcement bar. To protect the passengers in a side impact crash.
The bar is exactly where I needed to glue the below speaker pad. So I glued some 1.5" thick styrofoam above and below the bar so the pad could lay flat.



On the left is the styrofoam covered with "Damplifier", as you can see there's just a slight hump around the bar. On the right is the speaker pad installed.
The Speaker Pads get applied to the inner skin of the car door to absorb and redirect the rear wave away from the speaker.


The finished door with tweeter flush mounted. Sounds good, but it's a bit underpowered.
The current amp only puts out 60w RMS the speaker specs call for 90w.
The new amp pictured above has 111w.
