Sound insulation
Hey guys this is my first post over here and I hope you all can be of help. I got an 88 bronco and I've pulled the interior. I'm wondering what you think of sound proofing as well as help out the interior acoustic enviornment. I'm trying to get a plan together but I've got stuck here.
In the rear I've removed the panels and am planning on using diamond plate. I'm thinking of lining both the inside and outside of these with some type of a bed liner, either a spray in type, or the do it yourself roll on type. Should I put dynamat or some other type of insulation behind these, along the sheet metal. I am planning on using a spray in liner on the floor. I wonder if there is anything I can do or should do to help the floors sound transmission.
We'll start there
Thanks
Mike

Put soundproof foam or filler of your choice behind your speakers, or everything around them will rattle if they are of any quality.
That's my project for this weekend, pulling my doors and re-doing my Ranger's speakers with sound deadening material.

Thanks I'm hoping to find out about the actual ambient noise right now more than dealing with the speakers. But I've been thinking about what to use behind the speakers cause they do rattle a little now.
When you say behind you mean on the lip that they mount on don't you?
Thanks

What do you mean by that ranger? I'm confused myself..
But to answer your question Mike, I would put Dynamat (or equivalent) on all sheet metal that is hidden. I have done just about my entire truck with the stuff. I've done floorboards (2 layers thick, also this is in a Bronco II so there's a lot of area), firewall, sides (pulled panels and did all the sheet metal), and the headliner will be removed and the roof will be done next year, it's too cold now to do it. I've also done my door panels (outer skins and the part you see when door panel is taken off), and I've done the rear hatch as well. No more vibration noise

Ok ambient sound, yes dynamat away, that stuff is AWESOME lol.
What I meant was to put dynamat around the speakers, sorry I couldn't think of the name. I wanted to say dynomat but that didn't sound right and I didn't want to sound like an idiot. Guess I did anyways though huh? :-P

No not really. Thanks for the help.
I have the headliner out now, does it affect the headliner and or any other trim?
Does this stuff come off easily enough if I decide to sell the truck or anything like that. How much should I expect to pay for the truck interior. I don't plan on doing the floorboard because I plan to install a spray in liner. I was actually thinking of seeing if I could install the liner over the dynamat. Talk about stirring up a hornets nest of controversy. I need the floor to be water proofed and be able to deal with mud and sand and snow. I also want it to be as queit as possible.
Thanks

This stuff doesn't come off easily but, trust me.. people are going to want this in their vehicle.. it could be a selling point.
It doesn't affect headliner or trim because it's about 1/16-1/8th of an inch thick.. if that.
So you're going to put in the liner (like rhino-liner?) on the interior of the truck? Like floor boards? I'm not really sure if you could put that spray in stuff over dynamat.. but I can tell you, it's going to be extremely loud (road noise) inside the cab if you don't have carpet.

Yeah I'm planning on putting the Rhino liner or Line-X or maybe even that roll on stuff that you can do yourself.
I've thought about the carpet and floor insulation issues. I'm really kind of stuck right now cause carpet is a big problem in this truck. Construction materials, fishing and hunting equipment, off roading all don't get along with carpet. Maybe you have some ideas that could be helpful.
Trust me I know how loud it is without carpet. I took it out about three weeks ago and the thing is like an M1 A1. I thought it was bad before.
Thanks
Mike

Haha yep. I know how loud it is in my truck, I'm running without cats and a Flowmaster 40 series, with a turndown right before the axle. It reverbs up into the cab, but at the same time makes it have one heck of a growl too. I was running without carpet for about a week when I was putting in the soundproofing in (I only did it in my spare time). It was loud.
Didn't you say you're wanting this to feel like a new truck? What if you put in carpet and then some of those molded rubber mats? That's what I've done in mine, and it holds the mud out pretty good. Looks pretty nice too if I say so myself.

Yeah I do but not a fancy pants pretend cowboy cadillac. I want to be able to get it dirty without worry. I was actually thinking the reverse and throwing a few pieces of carpet down over the lining. I'm thinking now I may have to look to the outside for insulation.
Thanks

I would contact rhino-liner or just someone and ask if you can spray over sound proofing. You most likely will be able to. That would give you the sound proofing with your durable lining and be waterproof. At least this way you won't have rusting.
You can add carpet over the liner, if you're wanting the liner to be there just so you don't rust out. But the downside is, you might get mildew if you get it wet and don't clean up. If you clean up it shouldn't be a problem (wet/dry vac).

Could you put the carpet under the liner with the dynamat? Just a thought I randomly had while reading. Carpet is carpet is carpet, will it make any difference? Or can you even spray the liner on carpet? Guess that could be a problem huh?
