Sound deadening material applied to doors and back wall

[Stitchy]

Looks like a good job! Please share specifically what the proper trim tools that you used are. Thanks for the photos of the back sides of the door panels, it helps to figure out where the fasteners are. . .

On the doors, did you do the metal door and the skin?

For the floor I recommend Lizard Skin spray. You're going to have everything out and it's a more cohesive coverage.

Appreciate it, never used it before. Yes I did inside the doors and the panels

I added kilmat to the door skin, the window actuator panel and the trim panel. It certainly quiets the interior and isolates it from exterior noise. The Infinity Reference speakers added were an improvement especially at high volumes. Overall, it is a marginal improvement from stock.

I took my door card off on the passenger side because it rattled like hell with the B&O system. Lined it with the butyl and also put some closed cell foam on. Got rid of my door rattles, but I decided not to disturb the inner panel hiding the metal door skin. Wasn't sure how it came out and what box of worms I was opening or if I'd need to redo the gasket.

I took out the speaker instead and was able to reach my arm up in there pretty far. Got enough on the door skin that knocking it sounds much more solid than my other doors now. Now I just need to convince myself to do the rest of the doors and maybe the floor some day. i already did the rear under seat bins and back wall as those were the WORST with the factory sub vibrating them.

There is a YouTube on removing that inner panel and adding matting. The panel is the window actuator and once you have the glass detached it comes out easily. Watch the video to see the tricks. It makes all the difference.

This truck is already fairly quiet. I was hoping to get door panel to stop vibrating with the speaker. No go, some of you might like that vibration pulsing through your body. Not me, I'm old and I like my quiet. This truck is a quiet refuge on a noisy construction site and the a/c runs without the engine idling.

The door matting does not quiet the engine noise much. When it is revving, you can hear the engine. Not as satisfying as a vtwin but fine with me.

Hoping someone will make a wiring harness with line level out from the rear speakers to hook up a subwoofer

You need to connect to the fronts.
Here ya go:

What trim model do you have? XL, XLT or Lariat?

Any sound difference? Less road noise? Engine noise?

 

[Chawman]

I’m almost deaf but for you folks that can still hear looks like a good idea I don’t hear anything

Are the speakers your only audio upgrade? Did you replace the dash tweeters too?

I added the front door panel speakers and the rears. All Infinity Reference. I'm kind of an audio guy and the factory tweeters sounded good . They have great imaging and flat response from about 1200hz to over 20,000 hz. You could do a lot worse. I'm not playing with it.

The factory door speakers sound reasonably good if you keep the volume below 14. If you turn up the volume, the sound gets progressively distorted. The factory speakers are also limited in their bass response. The Infinity's can handle all the head unit can throw at it and delivered bass down to 40 hz. It's not hiphop loud but it is there. The head unit has enough power to run the speakers without distortion louder than I will ever turn it up.

I did buy some Tympano speakers with magnets as big as the speaker. When I tested them they were true one note wonders. They played 2K hz really loud and nothing else. Don't judge a speaker by it's magnet.

The factory system has active crossovers in the head unit which means each speaker has its own set of wires. I tested it with an RTA (real time analyzer). The door speakers seem to be cut off above 7khz and the signal to the tweeters is cut off below 2k hz. This means the crossover supplied by Infinity would require new wiring from the door to the dash and if it really were already crossed over it would not work. I left it out.

The rear speakers have no signal below 250 hz which mean you cannot tap it for a subwoofer. The factory rears were awful and the Infinity's there were a big improvement. One dot of killmat went behind each rear speaker.

The system sounds really good. I originally planned a DSP amp and a powered sub under the seat but I really don't need it.

Now if I can only get that pedestrian warning sound shut off I can really do some cruising.

wait. The doorspeakers have a high pass filter at 7k? Or 700hz?

Or are you saying the door speakers only get 7khz and below?, while the tweeters get 2k and up?
