Jeep is too loud

I have a 1990 Jeep Wrangler and it's SOOOOO loud on the inside. I can hardly understand the radio EVEN when it's turned up to max.

What are some tips? I'm trying to seal all of the inside to keep air from getting in.

I also think it's the belt making the noise, are they supposed to be that loud?

Would carpet quiet it down a bit?

Keep it cheap, please.

I know it's a jeep, if i wanted quiet i should've got a BMW. I don't care if there's noise, just want to be able to understand the radio when i'm IDLING.

no, the belts shouldn't make noise. yes carpets will help with road noise. a sound bar helps with the radio.
its a jeep, it will never be as quiet as a caddy.

I know... I never said i wanted it to be quiet. I just want to be able to understand the radio.

You know it's too loud when you've got the radio up to max and STILL can't understand what they're saying.

I'll replace the belts and see if that'll change anything.

Could be a combination of things, maybe it's idling too high, maybe you have a hole in your exhaust.

My '90 was loud and got louder the faster I went. Soft top flapping was my problem. I solved it by going with a new half top. I also replaced the soft uppers with glass sliders. This created less canvas surface area and tightened everything up. On the interstate I could hear the radio and in town I could hear a horn blow so I knew when the light had changed.

1: The Wrangler has zero insulation or sound deadening mats. Basically you are driving the inside of a sound megaphone.
2: Your Jeep is 24 years old. I am guessing your exhaust manifold leaks and the rest of the exhaust is probably garbage.
WHAT NOW!!!!
If I were you, I would coat the inside with rhyno liner and then carpet it. That will cut down considerably on the exhaust noise.
After that, check your exhaust for holes, cracks, or anything else that might be escaping before the muffler.
Check those belts. Put new ones on if there is any doubt. They are cheap.
Your sound system probably sucks. Even brand new Jeeps have crap radios and speakers. You might need to upgrade but, remember, it is a Jeep which makes it as secure as a burlap sack.
Now, all of this is taking into consideration that your complaint is that it is loud even at idle. We have not even began to address highway speeds...

Do you have a sound bar in it? It's attached to the roll cage. Speaker placements in a stocker are usually not ideal, you might want to change/add new speakers. They make some that fit/adapt into the body/windshield frame above the dash. Check out one of the jeep equipment catalogs (Quadratech, etc)

Goodluck

I have a 90 with the 4.2, carpeted, new Flowmaster exhaust and a sound bar and still can't hear the radio at highway speeds (it makes a nice clock though) but I can hear it fine at idle. The soft top is what makes the all the noise on my jeep. I bought a Bestop sailcloth hoping that would help, and it did some, but not significantly. If your jeep is that loud at idle, you should check the things the guys suggested, something is not right.

I think he realizes he drives a Jeep and its going to be loud, as he stated. We don't need to say "hey, its a jeep."

Lets try and help.

What is the noise? Is it a squeaky belt? As someone else said your exhaust mani could be (probably is) cracked. Could have an exhaust leak. A video would be nice. A sound bar will def help. I just did a DIY on one.

Check exhaust system first for leaks/cracks, etc.

Some heat shielding on the tub-side can also provide sound insulation

You can bedline the inside of the tub and add carpets, new top will do wonders, too.

You could also get a louder radio.

Tire noise can also be a big issue.

Yes carpet will help, if you want to really work at it, stuff insulation in the doors and sides of the tub. For me earphones and a beenie to hide them works best at highway speed, around town my soundbar and front speakers are fine.

I recall a gentleman on here carpeting the inside of his hardtop with adhesive and it reduced a lot of noise on the inside. I'm definitely planning on doing the same before next winter
