Sound-proofing/sealing doors

Gotcha thanks. That's partly why I thought of doing this in the first place - the "vapor barrier", is that the plastic stuff underneath the door panel? Cuz that was missing when I took off my doors, so figured I should cover that to minimize dust and stuff while offroading. That's the only problem offroading in the deserts of socal, gets real dusty.

Do you just use cardboard as a jig for the big piece to cover the door, or just cut to fit before removing the backing to stick? The guy in that video I looked at used "tesa tape" but that stuffs expensive.

 

Yea, the vapor barrier is the plastic seal between the metal of the door, and the plastic of the interior door panel. On my old MK2 Jetta, the door panels were cardboard! So having a good seal from the elements was necessary to keep the door cards from falling apart. Makes it much quieter and helps when the A/C is running, etc.

I just used 2 mil plastic sheet from Home Creepo when I repaired my Jetta's vapor barrier, it was one big sheet, I cut a larger than the door peice out, used silicone adhesive to stick it to the door, and then used a razor blade to cut the excess off.

The material I bought for my Taco came in small squares, when I lined the back of my cab, I just placed each sheet, then just placed the next sheet right up next to the last sheet. When I had to cut a piece down, I just eyeballed the size, used a razor knife and ruler to cut it, and used the scrap pieces to fill the gaps. It doesn't have to be perfect, that's why I got the black colored stuff, since my truck is black. I ended up overlapping some of the smaller pieces, and I might cover it with carpet anyways.

For the doors, it might make sense to make a cardboard template, then transfer that to the sheet, if you are going to use the stuff that comes in one big sheet. There are tons of youtube videos on this topic. The ********* guys have a good one that covers doors. I might end up running out of the stuff I got when I do the floor, so I might go the big sheet route for the doors, and then add a thin layer of carpet pad to add some dampening, I am planning on upgrading the door speakers at the same time, might as well do it right the first time.

This is what I got:

Vibro is Now Part of The Largest Manufacturer of Dampening Products in America- Our Black 80 mil (2mm) Product is The Finest OEM Certified Material in The Industry- 20 Thick Sheets per Box.

If I got with the same material for the doors, I'll just overlap each piece an inch or so to maintain the seal. Or place a layer of that thin silver duct tape down first, to get a good seal, then get most of the door with the Vibro stuff, as I said before, you don't need to get the whole panel, just a large part of it. The butyl rubber is very dense, and will absorb the vibrations from audio and road noise pretty well. The box of 20 squares was surprisingly heavy!

 

Yup, covered pretty much most of the interior & door panels with Dynamat years ago. People still trip out how dead the sound is when closing the doors and knocking on the outside panels.

 

Wow, would be so much work to take out all the lining but I guess ultra quiet in the end. I ordered the sound skins pro, comes with the butyl and acoustic foam. Should I put some of that 2 mm plastic between that and the door to seal from dust/dirt? Or the sound dampening stuff should be fine to seal on the door?

I'm still totally lost on the speaker wiring in another post (how to double check which wire is "+" and "-": https://www.tacomaworld.com/threads/speaker-wiring-polarity.558856/#post-18285672
My speakers are labeled "+" and "-" but not the wires coming from the truck (not even the stock colors either)

 

What about the OEM speakers? Are they labeled + & - ?

 

I don't know if they were the oem speakers. The wiring looks different than what I checked is supposed to be the stock colors of the wires. When I took out the old speakers, I just matched the way they were connected, they're good JBL 3 way speakers and just don't sound right. They sound way better in my camry.

 

Yeah my truck is a single cab, so it has minimal panels to remove.

I would just pick a color for the positive and negative wires, and just wire the speakers all the same. It won't make difference unless youre adding a sub, and then you can just flip the phase if it sounds off.

 

I did the same thing. I stripped the entire interior, swept, vacuumed and wiped with alcohol. Then sprayed with spray glue both the surface and the back of the sticky side of the frost king. It’s as quiet as a Lexus!

 

This!

 

Driving around town and on the freeway, it seems like the majority of just road noise is coming from the doors. I may do more once I finish the doors. How easy is it to remove and reinstall everything, like the carpet or roof? Are they held in with tabs like on the door?

@beez - so they just need to have the same connection, doesn't matter which is actually + or - ? That makes more sense, maybe I'll just do that thanks.

 

I get a lot of heat coming up front the center console area in my truck, and I want to clean up the amplifier wiring in my truck, so I'll just do it all at the same time when I pull the seat and carpet out. I have a bench so it will be less work I think.

Polarity of the speakers only matters as long as you get them all the same. Otherwise the speakers will be out of phase, one will be pushing when the other is pulling, and will sound weird. If you add a sub, then you want that to be in phase with the rest of the speakers, on my headunit I can change the phase of the sub so changing wiring isn't necessary.

 

I sealed all my sound deadening seams with rubberized undercoating inside the door.

 

I hope you didn’t seal the drain vents in the very bottom of the doors. If you did the doors will rust out.

 

Oh no didn't do that. The drains are wide open.

 

I’ll be interested to hear your feedback on the soundskins product. I tried finding some user info on it a while back but I couldn’t find much

 

@boostedka - yea there wasn't lot of info but figured I'd try it, I like that it comes mulitlayer. Let ya know when I get it and install

@beez - I forgot to mention that before too! when I'm offroading, tends to get pretty hot near the stick shift, guess just the design, no other place to dissipate when gettin overworked

 

Did the ENTIRE truck with deadener, foam, and MLV last year. A ton of freakin work, but the results are glorious.

 

Tell me more, where'd he shove the napkin, and what do you mean by screw cover?

 

I like that it’s multi layered as well. I’ve been looking into doing CLD tiles, MLV, and CCF. But idk how it would fit behind the door panel of these 95-00 Tacoma’s.

 

The screw cover that Im talking about is one of the two little plastic covers on the armrest, on the door panel.
