Classic Alpine sound

The sonic specialists at Alpine optimize their SPS-410 4" speakers for great range and impressive tone definition, even at low power levels. You can connect these versatile Type-S Series speakers to your factory stereo for an immediate sonic improvement, or hook them up to a powerful aftermarket stereo or amp for increased performance.

Mineral-fortified polypropylene cones are exceptionally stiff, yet lightweight, which means they can push out accurate upper bass and deliver clear midrange. Resilient rubber surrounds help keep the woofer centered for accurate cone movement, reducing distortion. Silk dome tweeters provide warm high notes that bring out the character of the instruments and vocals. Grilles are not included — factory grilles are appropriate for most installations.

Great Sound - Easy Install

John from Dallas, TX on 9/24/2017

2002 Jeep Wrangler
Crutchfield Customer Review (What's this?)

The kit from Crutchfield makes the install a breeze. I went to a big box store and got a different brand. The kit was wrong and an extra cost (over $25 more). The Crutchfield kit was included (right fittings, right plates, etc). Now to what mattered most -- the sound. The Alpines complement the soundbar audio behind the Jeep driver just right. The highs and lows are crisp and sound good at the volume needed when driving an open-top Jeep Wrangler. Before install, as you hold the Alpine SPS-410, you know the craftsmanship of the parts are going to deliver a superior sound (size of magnet, type of material, quality of capacitor used, etc.).

Pros: Quality Sound

Cons: I tried something else first and had to install 2x

Great speakers, well made

Great little speakers made of excellent materials.



Service as it should be

Ryan from Bloomington, IN on 5/7/2017

2002 Jeep Wrangler
Crutchfield Customer Review (What's this?)

The speakers are great as expected, and the Crutchfield vehicle specific installation instructions caused me to spend a total of about 10 minutes on installation. Everything fit as expected and functions as it should. I doubt I will ever purchase anything vehicle audio related from anyone other than Crutchfield.

Pros: Easy installation Right price Great customer service

Cons: Wish I could have fit speakers that would move air, but limited by the wrangler

Fits a BMW X3

Robert from Wake Forest, NC on 12/27/2016

2007 BMW X3
Crutchfield Customer Review (What's this?)

Fits a 2007 BMW X 3 even though the fit guide does not say so. Requires a washer on the 3rd of 3 car mounting bolts as the speaker has 4 mount points. Also requires the car wiring to be cut as no kit is available, though Crutchfield was able to identify the positive and negative leads - which are not obvious on the Bimmer. Sounds good given the door location.

Pros: Sounds good. Easy to install in spite of not coming with an installation kit.

Cons: No installation kit, but still great tech support from Crutchfield.

Alpines forever

Awesome sound. Fit perfectly,even though the fitment said it wouldn't ( don't know why that is). Just had to adjust my HPF and I could hear parts I couldn't with my old pioneer's. Love em..

Pros: Easy install,fit like a glove.

Cons: None as of now

seems the wrong recommendation

ge from union, NJ on 6/4/2016

2004 Pontiac Grand Am
Crutchfield Customer Review (What's this?)

rated middle of the road....can't really say if bad or good. bought due to name and recommendation for oem replacement. but, they are a rated 4 ohm speaker with a thirst for 45 watts. speakers i took out of the car, oem. are marked 2 ohm, think system is 30-35 watts. was told the improved sensitivity would make up the difference. cannot even hear these unless volume up almost all the way. did end up using the mounting plates for a pair of jbl, with higher sensitivity and a supposed 2 ohm rating. to be fair they are listed as 2-4 ohm, don't see how they can be both but did read where buyers have tested and got a 2 ohm reading, maybe they are really a 3. at any rate, i can hear the jbl speakers, and they do what i wanted the alpines to do, bring in the clearer mids. still have to push them to compete with the rear powered 6x9s, but i get double the sound out of them. would of had to drill to mount without the plates from the alpines, but bottom line, the alpines were the wrong recommendation. crutchfield has the jbl, i got them elsewhere. the alpines will probably go up on ebay, for a loss.

Pros: could not tell.

Cons: poor match for gm oem monsoon. wrong ohm rating and higher wattage results in weak output.

Awesome Sounds

Pros: Just plain AWESOME!!!

Cons: None

Great clear sound. Great for an oem replacement without running an amp.

Pros: Clear sound.

Cons: Bass is a little low but with a sub on the way there is no problem.

Great sound!!

2006 Scion xB
Crutchfield Customer Review (What's this?)

Very crisp highs and great midrange from these speakers. Driven off the front speaker connection of an Alpine ILX-007.

Pros: Will fit in the dash location of a 2006 Scion xB with slight alteration.

Cons: A little bit pricey.

Absolutely amazing

Roy from Austin, TX on 2/28/2016

Crutchfield Customer Review (What's this?)

These speakers are exactly what I was looking for. I don't know much about ranges and all that stuff, but I will say I'm hearing insturments I've never heard in music I have had for a long time. I find myself in my pickup just sitting there looking up songs and watching YouTube videos just because the sound quality is so enjoyable. These speakers were hooked up to a Sony MEX-N5100BT deck.

Pros: Clear, crisp, sharp. Install was easier then deciding where to eat dinner. Great look. Website photos are dead on.

Cons: Well, Not really great on bass but would you expect from some 4in. I plan on getting a swoofer soon.

Crutchfield Customer Review (What's this?)

Installed these as replacement dash speakers in and 2003 Porsche Boxster. After cutting down the original mounting bracket these popped right into place. The adapter plug that came free with them made the connection to original wiring literally a "snap". Great speaker that brought real fidelity back into the car!

Pros: Ready adaptability to original speaker installation.

Cons: None.

Crutchfield Customer Review (What's this?)

Amazing speaker for it's size. I was locked into a 4" speaker and needed something with reasonable overall performance. This speaker delivers great highs as expected but also good mids and some bass.

Pros: Much beter than expected overall sound and volume from a 4" speaker.

Cons: Would be nice if it came with grills if you need them.

1986 toyota truck under dash speakers

c1blh from Utah on 6/1/2015

1986 Toyota Pickup
Crutchfield Customer Review (What's this?)

What I needed was a high quality set of speakers that reproduce classical music at a moderate volume setting. These speakers do very well on most of the range of sound. There is no way these little speakers can reproduce the sound of very low pipe organ sounds, yet they do provide a very elegant sound on most classical music sounds. They were easy to install. Old speakers had only two corner mounting screws, and the new speakers have 4 corners. One corner tab will need to be removed on each speaker so they will fit,

Pros: The speaker wire adapter connection worked very well. Very high quality of sound provided by these speakers.

Cons: I needed to nip off one corner mount on each speaker for this install on a Toyota truck 1986 with speakers under the dash on left and right sides.

Excellent speakers

mikeymike from South Boston VA on 3/3/2015

2008 Toyota FJ Cruiser
Crutchfield Customer Review (What's this?)

These speakers brought me everything I wanted. I own a FJ Cruiser and initially they did not fit in the speaker holes in the dash. But with a little custom work I got them to fit perfectly and it was well worth the effort. The stock speakers were tiny little tweeter like speakers and replacing them with these was a step in the right direction. I also bought another set that I am going to be installing in the rear openings on my Cruiser. Haven't gotten around to this yet but can't wait to get more sound behind me to match my subs already installed.

Pros: Clear Precise Loud

Cons: None

Great Product

Crutchfield Customer Review (What's this?)

Got these for my husband for Christmas for his beloved '91 4-Runner. He installed 4 speakers and a JVC stereo in about 2 hours. My product advisor at Crutchfield was excellent. I would have to say my experience with Crutchfield was the best on-line experience I've ever had.

Pros: Quality. Price. Easy installation.

MattC from Wilton, CA on 12/30/2014

Crutchfield Customer Review (What's this?)

I've always associated Alpine with quality. These little speakers did not disappoint, they sound great for a front set of speakers.

Pros: Good quality, nice highs

Cons: Not an exact fit as stated in the guide.

Great Speakers for the money! They beat Mercedes factory speakers.

GregM from Columbus, OH on 11/16/2014

1987 Mercedes-Benz 300D-T
Crutchfield Customer Review (What's this?)

I bought these to replace Mercedes factory speakers in my daughter's W124 300D. We've owned this car since new and the sound system has always been a big disappointment. I should have bought these a decade ago. These were used to replace the factory 4" rear units as well as the the factory 5" front units. The ears on the speakers had to be trimmed using a small cutoff wheel on a Dremel tool in order to make things fit in dash pockets..... but they work perfectly and look like factory... reused factory grills without an issue. I would buy again without hesitation.

Pros: Very nice quality sound for the money. Tonal range is vastly superior to factory Mercedes speakers at about 1/5 the price. Minor tweaks to the mounting ears so that they would fit into the Mercedes speaker factory mounts. I used these to replace the factory 5" front units as well as the factory 4" rear units and they all sound superior to what Benz supplied from the factory.

Cons: No complaints.... would buy again!

Bob T. from Loveland, CO on 11/6/2014

2000 Porsche 911 Carrera
Crutchfield Customer Review (What's this?)

This is the simple solution for us restoration car nuts. Crutchfield recommended these as a direct replacement for all four 4" stock location speakers. Bolt right in, can use stock grills so no mods needed. They sound surprisingly rich, Quite a bargain for me. I'm very satisfied.

Pros: direct replacement for my stock speakers, easy to install, sound great/.

Cons: Bargain price, but now I want to upgrade further.


Guy from Fairfax, VT on 9/23/2014

Crutchfield Customer Review (What's this?)

After having no luck locally finding anyone with speakers that would fit my car or someone to install them I called Crutchfield. They suggested what to buy and how to install them. Guess what, they were a cinch to install and sound great.

Crutchfield Customer Review (What's this?)

AUDI OWNERS BEWARE I Bought these to replace the blown factory speakers in my front doors. The factory ones were 41/2 not 4 and there was no way to mount it with what I was given. I had to go to a audio shop to have them installed by gutting the old speaker and putting the new one in it. Other then that great speakers.



Little speakers that could!

saabsuperaero1 from Butler, PA on 4/21/2014

1994 Saab 9000
Crutchfield Customer Review (What's this?)

Hey, what can I say, these are Alpines! Legendary Alpine clarity with rich deep lows, great mid range, and infinite highs. These SPS 410s are being used as front speakers in a SAAB 9000 Aero Hatchback. The stereo is simple, a Clarion NZ 500 , two 4" Alpines in the front, two 6" Alpines in the back, a 150 watt Fosgate amp powering a 10" Pioneer sub in the hatch. Not overly complicated but sounds tons better than the factory Bose in my CTS, and Lexus systems. Loud and clear all the way up to max.

SteveL from Katy, Texas on 5/14/2013

1999 Porsche 911 Carrera
Crutchfield Customer Review (What's this?)

I replaced the factory speakers on my 1999 Porsche 996, both dash and backseat panels, with Alpine SPS-410's. The sound quality was vastly improved and much better than when the vehicle was new. Improvements in the bass was most noticeable but the high ends were clearer and crisper. A great improvement which allowed me to use the original speaker grills.

Pros: Improved bass and high end. Fits in the existing enclosures and allows use of the Porsche speaker grills.

Cons: Minor modifications required to attach the speakers to the grills.

Awesome 4"

Great sounding speakers. Crutchfield said that they would not fit in my car, but after talking to the helpful reps, they allowed me to purchase the speakers and attempt a custom install. With a little modification, they fit flawlessly.

Pros: - Sound great. - They are Alpines!

Cons: - Lack bass (expected because you should have a sub system with these)

Great Jeep Wrangler Pod Speaker Replacement

Brandon from Texas on 9/23/2011

I used these in the stock Rubicon 7 speaker system. Removed the tweeter and woofer from the pods in the dash and sound way better than any 5 1/4 you would stuff in there without an enclosure. These are much nicer sounding and less distorted. The mids are there too. Dont expect bass but they do breakup less than the 5 1/4 with plates mounted in the same location. The stock speakers have bass blockers stock inside the enclosure cut the green and black wires off the stock speaker and solder the new alpines into the bass blocker wires, green is NEG and black is POS. Not to be confused with the plug wires in the dash, they are black red/brown LEFT and Violet/Blue on he Right. I am talking about the wires in the 7 speaker system Pods. Get these for the Wrangler! I got a great deal on these. They are a steal!



Nice little speakers

Great Bane from Potomac, MD on 9/5/2011

1984 Porsche 911
Crutchfield Customer Review (What's this?)

We bought these to replace the original rear speakers in my wife's 1984 Porsche 911. The original sound system had never worked well. We put a new Kenwood HD receiver in dash and a set of the Alpine SPS-510s in the door. What a difference. You can actually hear the music even with the top down. For less than $300 we put a great sounding system into her car. Very clear and sharp sound. Since the car is a convertable we didn't want to go overboard with the system since weather and theft are much more of a problem in a drop top. Very satisfied with the product and the service we received from Crutchfield.

I installed these in the rear doors off my Subaru along with the 6-3/4" component system and Alpine deck and they sound great. Everybody knows you can't expect much bass from a 4" speaker but these little dudes keep you rockin' down the highway with good sound and they are very inexpensive!



Very nice sound

I bought these speakers to replace the dash speakers on my 2003 Jeep TJ, and all I can say is that these speaker give a great sound despite their small size. Any genre of music sounds very good through them and comes through crisp and clear.

no they are not waterproof you would be better off going with a marine style speaker for motorcycle application. :-) [ ANTHONY RYAN  Apr 29, 2014 ]
They are not Marine Grade. I've got a Harley & I'd go with something else if you do ride in downpours... They sound great in my girl's Subaru, though. [ PAUL  Apr 26, 2014 ]
Mike, I use these in two different applications. The sound bar of my jeep and in my boat. They are constantly exposed to indirect moisture and perform flawless. I think the motorcycle application would no different from a boat. Thumbs up and enjoy. Crutchfield does an amazing job of sales and service after the sale. [ WILLIAM S  Apr 26, 2014 ]
