Hello forums,

I spent today creating a series of recording in a Jeep Wrangler of what it would sound like with speaker upgrades. I recorded the factory speakers with hard roof, factory speakers with headlined roofs, Kick10 speakers, Kick10 with headlined, Kick10 + Kick25 speakers, and Kick10 + Kick25 Speakers with headlined.

Each recording was created in an acoustically controlled environment with 5 microphones; 1 on each headrest and one on the armrest. I am not providing individual recordings as it would take a whole other day, so I mixed all the microphones together to create an average of the hearing envrionment.

None of these take into account of equalization or difference in your listening environment. No-polyfill was used during recording. However, some were added after (Personal Preference: The polyfill made everything sound better)

There are other variations upon this which may improve or detract your experience. I hope these help you with your decisions.

Factory Speakers:

Noticeably thin in the higher frequencies. Lacking body and mid.

Factory Speakers + Headliner:
https://kiwi6.com/file/gcv6mvonge

Noticeably thin in the higher frequencies. Lacking body and mid. Better acoustic environment.

Kick10 Speakers (Stock tweeters)
https://kiwi6.com/file/kme06xwjkt

Well-bodied throughout in frequencies. Acoustic environment echoes.

Kick10 Speakers + Headliner:
https://kiwi6.com/file/n8zyahfv9e

Well-bodied throughout in frequencies. No environmental echoes. Better mid-frequency penetration.

Kick25 Speakers (Signal Attenuated) + Kick10 Speakers:

Higher frequences noticeably sharp and somewhat harsh - Your age may dictate otherwise (The author of this post is in 20s and works in music)

Kick25 Speakers (Signal Attenuated) + Kick10 Speakers + Headliner:
https://kiwi6.com/file/f1x4lk58q4

Higher frequences noticeably sharp and somewhat harsh - Your age may dictate otherwise (The author of this post is in 20s and works in music). Reduced environmental echoes. Better mid-frequency penetration.

I hope you all find this useful in considering for upgrades.

Personal Opinion: I find the Kick25 Upgrade to be redundant - The higher frequencies are very harsh.

Addendum 1: The vehicle was equipped with the 130.

Addendum 2: No amps were added at the time of recording.

Addendum 3: Factory subwoofer.

Addendum 4: Outside environment acoustically silent (<5 decibels)

Those are all great but my new Sahara has highway wind noise which sort of makes the money I spent on the upgrade speaker system a waste of money. I am being told that highway wind noise is a fact of life with Wranglers.

The headliner really helps with the wind noise, if you have a hard top. If you don't have a hard top, that would help quite a bit as well.

I've noticed that on the rare occasion, I don't have the stereo on, I get quite a bit of noise coming from the door seals. I'd bet replacing those would help. Maybe smaller mirrors. Maybe try folding them in and see if it changes anything.

Highway wind noise reduced by 5 - 7 decibels with headliner. Will also create more porous surfaces to trap acoustics within the car for better quality sound. The overal quality is that you hear less wind noise and acoustic insulation makes your speakers better.

To reduce windnoise further, line entire bottom surface of hardtop with a carpet or sound insulation material rather than headliner. You can also replace your windshield with bullet-proof polymerized glass to cut another 5 decibels down. But this is expensive and increases fuel consumption. But... that's overkill (select government vehicles do this and the difference is astronomic.)

I should add - Listening to these, depending on what speakers you're using to play them, presents a whole other set of issues as well. Since I can't upload lossless recordings, these compressed files will lose some character and quality.

These will give you a -general- idea of what things sound like.

Is the OEM windshield on the JK already acoustic glass?

I also notice that it looks like there is some factory foam in the A pillar cavity (though I only see it on the passenger side, not the driver side)

OEM Windshield is shatter-proof polymerized glass, not acoustic glass (thicker but not usually shatter proof).

Factory Foam to reduce vibrations but not improve acoustics.

to add to the earlier comments, I definitely think the headliners improved my sound in my Jeep
It should - bare, smooth surfaces are the bane of acoustics. Sounds bouncing off these surfaces convolve to the interior of the car and bounce around much longer than rough surfaces, so it makes all your speakers and music sound boxy and muddled.
