Love them! I had to drill new holes because the factory holes didn't line up, but that's okay, it was very simple. They sound great!

Pros: Great sound.

Cons: Holes did not match factory holes.

Not worth your time, money of effort

Craig from ERIE, PA on 6/8/2025

2025 Jeep Gladiator

Verified customer (What's this?)
Verified employee review (What's this?)

I bought these for my 2025 Gladiator roll bar because it said they fit and would only require drilling new mounting holes. They might fit someone's Gladiator, but they don't fit mine. They are finally installed after sitting in my back seat for two days and a call to the tech line for guidance. There were no instructions other than drill new mounting holes. The 60+ page Crutchfield book explained how to remove 5 screws on the speaker grate and 3 screws on the OEM speaker.....gee, thanks. Nothing for installation and the tech guy was also no help. I used Nothing that came with them but some screws. So, the speakers are sort of surface mounted on the roll bar sound box because they don't actually fit in the OEM speaker holes, that defeats the design of the sound box. Sound? Fair at best, no real bass because of the gaps. Bottom line.....I would not buy these again, and would not recommend them to a Gladiator owner . This juice just isn't worth the squeeze.

Pros: None that I can find

Cons: Read the review

Very decent speakers for the price. I needed to replace the factory 4" speakers in my Jeep Wrangler roll bar. Easy install. Immediately noticed a fuller range in response. Only pushing them with the factor head unit right now, but eventually I plan on integrating an amp and then I know these Alpines will really show thier capabilities. Very satisfied.

Installed these in the dash and roll bar on a 2022 Bronco with the standard sound system. While it didn't turn it into an audiophile system (obviously), it did significantly upgrade the sound quality. Easy upgrade for not a lot of money.

Nice upgrade to my 2023 Bronco in the dash and the rear pods. Really wakes up the B & O system and provides much crisper sound for a minimal investment. Crutchfield is always excellent about sending the correct harnesses and they were a perfect fit.

Pros: Well made, good price

Installed in front dash of 2023 bronco with factory head unit and 600 hz bass blockers. Highs are much more clear than stock speaker. Occasionally, have sounds that are a bit tinny. Not sure if head unit or speakers.

Pros: Clear highs. Not overly bright.

Outstanding speakers. I used this to replace the OE dashboard midrange speakers on my 2022 Lexus NX450H+. The OE speakers were dull, lifeless and muddy sounding. These Alpine speakers really bring out the crystal clear vocals and crisp high frequencies. Highly recommended.

These speakers are definitely better then the stock ones that were in the truck. Installation of them was not bad at all. They do require you drill holes because the oem speaker was not bolted in from factory.

Verified employee review (What's this?)

Fairly easy installation, for those looking for the instructions, you didn't like them yet, flip the box upside down, there they are, printed on the bottom side of the box, that gave me a chuckle Other than that, they sound great, the adapter was pretty cut and dry, the only warning is the tabs for the connections on the speaker can be a little bit on the weaker side so hook it up carefully and leave it be

Pros: Great sound, well balanced, easy installation

Cons: If you need something to do all day, don't do this, only took about half an hour

I have 4 speakers running off amp just 50w and I added these to dash running off head power 16w only just to complement door speakers and big differance. I disconnected doors just to hear these alone and wow these sound good for little 4'' These really helped my front stage sound. They dont play over the doors with 50w but sure did help.

Pros: sound quality and Clarity All the accessories included with speakers brackets screws etc to fit in 4x6 opening.

Cons: none

Wow!!!! Perfect for 2023 Bronco Wildtrak Every vehicle that I have owned for the last 20 years has always had its sound system upgraded with apline components, from Type R Speakers, Type R Subs, and Alpine Amps. I was hesitant about buying the Alpine S2-S40 speakers for my 2023 Bronco Wildtrak because there wasn't a Type R 4 inch in the line up, but after replacing the factory B&O 4 inch fatory speakers with Hertz Dicie's, I realized they were just not that Alpine Quality that I was accustomed to, so I purchased just 2 of the Alpine S2-S40 for the roll bar just for testing and Wow They blew the Hertz 4 inch Dicie speakers out of the water with that Alpine Quality Sound. My Wildtrak Sound System is now comprised of : Alpine 8 inch SBR-S8-4 enclosed Type R subwoofer in the Rear Alpine 6.5 inch Type R Hi Res Speakers in the Front Kick Panels (5 Stars) Alpine 4 inch Type S S2-S40 Hi Res Speakers in the Roll Bar (5 Stars) 3 Hertz Dicie Speakers: Right,Left Dash Corners and Center Channel (soon to all be replaced with 3 more S2-S40's) All on the factory B&O amp because I haven't decidied on wich Alpine amp to install yet, and believe me it sounds amazing. So I could almost imagine what it would sound like once the amp and (3) other S2-S40's are installed.

Pros: Has Type R Technology Great Hi Res Sound Great Price

Cons: None
