Worthy materials

Alpine's carbon fiber-reinforced plastic woofer cones provide next-level sturdiness but are also agile enough to handle the complexities of the midrange. The big multi-roll rubber surround contributes to reduced distortion for a cleaner sound. Separate silk dome tweeters provide all the precise details that bring out the character of the instruments and vocals. If you've never experienced Alpine sound quality, these speakers are a great place to start.

Grilles are not included; the factory grilles should be suitable for most applications. Optional grilles are available for custom installations.

Great quality and sound



Impressive sound

2001 Toyota Camry
Crutchfield Customer Review (What's this?)

Installed these in my work car, a 2001 Camry LE with the factory high powered 3 in one head unit. Wasn't really expecting much, and the factory speakers were simply horrible, and sounded awful. Installing the medium sized woofer in the factory location was cake. Finding a proper tweeter location...not so much. Used the trim covers in the door where the factory tweeters in the XLE would go.(front corner of door where mirrors are mounted) Cut the hole easily, but had to modify the mirror studs for fit. Once that was done, buttoned everything up, aimed the tweeters, and put in a great rocking Stevie Ray Vaughn CD...I was overwhelmed by the Alpine's speaker performance. Highly Recommended. Can't wait to add a modern head unit (looking at the Pioneer wireless Android Auto unit) By the way, the 6X9 Alpine coax I put in the rear deck are amazing too!

Pros: Great sound from their location. Hoping the sound is even more impressive when I finally install a proper modern head unit.

Cons: Having to search and modify a spot for the tweeters

God, clean, crisp sound, fit great



Amazing sound, extremely clean, tight bass response, even at low power

Stephen from Lutz, FL on 10/6/2018

Crutchfield Customer Review (What's this?)

These speakers are amazing, let me just start with that. I have been listening to them for about 2 weeks now, so I could get a good feel for them before writing this review. These replaced my factory door speakers in my 2006 Corolla. The sound quality is nothing short of amazing. Toyota does not making installation super easy, but with the speaker brackets included by Crutchfield they fit perfectly. Getting a proper fit for the tweeters is not very easy due to how the factory ones are installed by Toyota, but these are just the right size so with some hot glue they adhere to the factory bracket just fine and installing them in the factory location was a breeze. The in-line crossovers are very slim, making fitting them into any tight door space easy. I can't rave enough about the sound, especially the bass response; bass is super tight and clean, with absolutely no distortion, even at mid-to-high volumes. Compared to the factory speakers, these produce so much more bass, and the tight punches and clean sustained bass is mind-blowing considering I do not even have these amped. They are powered by 22 watts RMS from my Kenwood Excelon receiver. I'm sure that when powered to their full potential it will be even another level of amazing. Granted without a sub I am not getting a lot of bass on extremely low frequencies, but everything above the extremely low sounds is amazing even at 22 watts. BUY THESE!

Pros: Range of tweeter installation brackets supplied, top-quality sound, extremely clean bass, excellent power handling

Cons: None

Crutchfield Customer Review (What's this?)

They sound amazing!!! Nuff said

Pros: Great sound filters...strong cones...tweeters have great bolens with sound coming from cone..not screaming!

Cons: Respect the 3ohm...must stay with in frequency and hertz or it will have your amp on fire and send in protect mode

Great Upgrade!

Kaleb from Marlow, OK on 8/19/2018

2016 Jeep Wrangler Unlimited

The speakers themselves sound great! I am a musician, so I am a sound snob and I am impressed with these speakers. If you are looking for a lot of low-end you won't find it in these, as that is the nature of mid-range speakers, but the clarity in them is unreal.

Pros: Easy to install and is a great upgrade to factory speakers

Cons: Instructions are vague and there is little to no bass in the speakers

Crutchfield Customer Review (What's this?)

Tight mid bass, amazing vocal reproduction, smooth highs that are not harsh or overwhelming. Good construction quality, and simple straightforward installation.

Pros: Good quality Easy installation Price is on point And it just sounds really good

Cons: None

Looks good, sounds better

Hunter from Brownsville TN on 6/2/2018

2003 GMC Sierra 1500
Crutchfield Customer Review (What's this?)

Larger than any other 6.5" speaker I've put in my door cone diameter and basket. I was able to retain the factory clamp with other 6.5s but I needed adapters for these because the clamps would crush the surround. The speakers are well worth the extra work, they've outworked and outperformed pioneer and kenwoods. Crystal clear sound and great bass without an amp, they'd probably sound amazing with one. You can't go wrong with alpine

Pros: Clean sound Amp not needed but would help Plenty of wire for tweeters Comes with many tweeter mounting brackets Tweeters sound great

Cons: None so far

Excellent component set, give them some power!

Ken from Bluffdale, UT on 5/13/2018

2016 Mazda 3

Excellent fit and easy to install, I appreciated the extra pieces to help mount the tweeters. I was able to mount the woofers with no issues, and the tweeters fit inside the factory sail panels of my Hyundai Santa Fe Sport with no problems. I had to literally carve up the tweeter of my previous set (JBL Stage) to get them to fit in the sail panels - these fit under the factory foam just fine. The sound is excellent, I am sending 50 watts CEA rated power to each side and they handle the load like a a champ. I am not building a competition vehicle, but these are great for a daily driver or a road warrior who enjoys good music during the trip.

Pros: Ease/Flexibility of installation Balanced highs No bulky crossover box Bi-ampable if you want to have active crossovers

Cons: None so far

Mike from Carrollton, TX on 5/1/2018

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

Awesome Product. Running 4 of these with an JL Audio Amp with 70 RMS per channel. Even with the AMP turned up a little more than 1/2 of the potential these speakers are clean. The mid bass is tight and the tweeters are super crisp. Can't go wrong with these.

Pros: Great clean sound.

Cons: Nothing so far.

Great all around speaker. Nice tight mid bass and very clear highs. Not harsh high, more like silky smooth highs. Pushing them with the Alpine KTP-445A Power Pack. More than happy with the set up!

Product Research


Woofer Mounting: Without an adapter, the woofers fit standard 6-3/4" applications. Given their required cutout, they will also fit standard 6-1/2" applications without an adapter, but new screw holes must be drilled. Using the included adapter brackets they can be mounted in a variety of standard 3-hole 6-1/2" applications, Ford 4-hole 6-1/2" applications, and non-standard 6-3/4" applications, without any modification.

Tweeter Mounting Options: The tweeters can be flush mounted using the supplied flush mount brackets and rings. Once mounted, the tweeters can swivel approximately 20° for optimum imaging. The tweeters can also be mounted in factory tweeter locations behind factory tweeter grilles using the supplied stealth mounting brackets. (The stealth brackets have a multitude of tabs used for different mounting configurations. When not needed, the tabs can easily be removed. The factory location measurements in the chart below are generally minimums, with some tabs removed.)

  Flush Mount (swivel) Factory Location (bottom mount) Factory Location (top mount) Surface Mount (under factory grille)
Mounting Depth 0.66" 0.714" 0.8" 0"
Mounting Height 0.417" 0" 0.058" 0.8"
Cutout Diameter 2.0" 1.723" 1.723" N/A
Frame Diameter 2.288" 2.425" 2.425" 2.57"

Crossovers: The Alpine S-S65C features low-pass crossovers attached to each woofer's input terminal and high-pass crossovers in-line with the tweeters' speaker wires.

1 question already asked

The woofer and tweeter work together to give you a 4 ohm load. If wire two sets of these together in parallel, then you will have a 2 ohm load My Bio: [ Paul  Feb 11, 2019 ]  Staff
