Quiet please!

Can anybody help with the awful road noise/tire noise/exhaust noise I get when driving my bronco? It's a rhino lined tub on 33's with 2.5 inch lift and bcbroncos top (I know it won't be whisper quiet!) I need carpet but but do I dynamat and carpet? Just carpet? I have wakeboard speakers on the roll bar and I can't hear the stereo unless I blast it full power. Which I am sure is hurting my already degraded hearing from a lot of shooting sports. What is the best/most cost effective solution to getting this thing easier on the ears? Any help appreciated.

Dynamat, or equivalent, under the carpet and everywhere you can put it. I just redid my doors with a dynaliner type product, MLV, and new felts. Doors are often overlooked.

Carpet felt wasn't something I was finding on the regular bronco part sites. That's why I asked on here before buying stuff. Good thing there are guys like you to help dummies like me out! Do you think it will help much with noise reduction even with the soft top or am I just wasting money?

Now who should I buy from? I would like a pre-fit kit

Ditto on the felt.... I did that too. I don't know of anyone who sells a full felt kit including the wheel wells. I know Tom's has a full floor kit. I did mine myself. It's really not difficult. I have felt over foil backed foam which is over a dynamat type product. I got foil backed felt from JC Whitney and spray glued it to the foil backed foam. You will notice a difference even with a soft top.

Carpet and padding will keep some of the noise out, but some will still get through. You need to pad the rest of the interior to absorb those sound waves. If you don't install padding in the top, sides, and doors, the sound will just bounce around inside the cab like a tin can.

A good example of this is in school gymnasiums. Since you can't put mufflers on the spectators mouths, padded panels are attached to the walls and ceiling to catch the sound waves.

I used some of that foam sheeting from Home Depot attached with spray glue between the top braces and installed the headliner right back over it. I used the same stuff under the side panels and inside the doors.

It's not necessary to get 100% coverage, but it all helps to trap those sound waves.

Once you get rolling with the basics then go to Bronco hut and get the fiberglass liner panels for the top and bed sides and stuff the space behind them with insulation.

Dynamat and carpet helped me out a LOT. I have a louder exhaust, and my floor was also lienex'd and before carpet it was crazy loud while driving. Seem to just echo off all that metal. Now it's waaaaay queiter. I'd say far less than half as loud as before. It's worth it for sure. Top up or down.

Road/tire noise is from tires. Don't care how much you blanket the body you are still fighting the noise. Change the tires to something that rolls quieter.

What fan do you have on the engine. Fan roar is generally a huge noise generator. Going to a clutched fan (like the Explorer front dress) can really quiet up the fan.

Exhaust is so simple I am not even going there.

Aftermarket open air cleaner? Those allow a lot of intake noise. Factory style will be quieter.

Be careful on the dyna product which has the glue on tar like surface dynaliner. I avoided using that over the hot areas.

What I found for use in mine is 2 versions of dynamat: Dynapad and dynamat. One is pretty hefty and has the tarlike stuff encapsulated between layers. I also went to an upholstery shop and bought enough of that silver backed fluffy carpet backing stuff for about $40, like slowleaks stuff above. I am going to use dynaliner on the walls of the rear quarters behind the 1/4 panel, that stuff will stick there no issue, didnt want to use that stuff right over the engine/tranny tunnel. Nor glue anything to the floor incase it did get wet from rain or such. I am doing what is shown above, cutting panels and taping it all together with this industrial nuclear powered tape. Duct tape on steroids.

As noted above, underspray really doesn't help, and once you cure the floor and 1/4 noise, the last place is the firewall which Im using the WH firewall factory looking replacement plus another layer of my silver backed upholstery material.

Tire noise is probably worn tires. i just replaced my KM2's that had 25,000 on them for same version new. Like night and day, My jeep is quite at 80 again, i never realized as they wore they got louder, like B29 loud.
