You'll have to custom-mount tweeters or midrange speakers, which usually requires drilling holes and running new wires.
Alpine Authorized Online Dealer

Highlight the highs

Alpine is known for quality sound and that reputation carries straight into their SPS-110TW tweeters. If your vehicle's speaker system sounds dull and unfocused, you'll be impressed by the excitement and detail these Type-S 1" tweeters will add to your music. And, if you like to turn it up loud, these silk domes will handle up to 150 watts RMS so they'll fit right into a high-performance system.

It's all in the details

These tweeters deliver rich high-frequency performance without ever turning shrill. An EQ ring in front of each tweeter helps to disperse the sound evenly, while the tiny outboard crossover network ensures the tweeter receives only the frequencies it was designed to handle.

More natural sound

Alpine includes hardware for mounting the tweeters in the best spot in your car. Once they're installed, you'll hear all the details in your music, and all the instruments and voices will sound more defined and natural. You can choose from four tweeter levels so the high frequencies are balanced with the rest of your speaker setup.

Product Highlights:

  • 1" silk dome tweeters (pair)
  • flush-, top-, and bottom-mount hardware included
  • external crossovers with 4-way level control
  • power handling: 5-150 watts RMS (450 watts peak power)

  • impedance: 4 ohms
  • sensitivity: 88 dB
  • flush-mount depth: 11/16"

You can also install the tweeters behind factory grilles using the included stealth mount brackets. The stealth mount brackets can be top or bottom mounted. The installed tweeter dimensions are:

  Flush Mount (swivel) Factory Location (bottom mount) Factory Location (top mount)
Mounting Depth 0.638" 0.8"-1.12" 0"

Note: The stealth mount brackets have multiple tabs that can be trimmed to match your installation (thus the range in the table above).

Alpine Tweeters

Written By Anonymous, Georgia on Tuesday, June 03, 2014

Crutchfield Customer Review (What's this?)

This is my second set of Alpine SPS-110TW tweeters for my truck. The first set met an untimely end on my part for not adjusting my settings properly at first. Learned my lesson and with this set and they installed easily without needing to replace the whole housing (push in and twist the back of the tweeter housing to open it and pull the old tweeter out). The sound from them are crisp when adjusted properly and fill the cab of my truck with notes not normally heard making the experience that much more enjoyable.

Pros: Crisp sound, easy installation

Clear sound

Pros: Really like the included decals. Added a little detail to my canyons dull interior.

Cons: None

They really improved the sound

Written By Rick, North Georgai on Sunday, March 02, 2014

Crutchfield Customer Review (What's this?)

I replaced the factory front tweeters in my '12 F250 and it really helped brighten the sound. I dont hear well above 800 hz so I needed that.

Pros: small enough to fabricate holders for

Cons: no direct bolt in. must fabricate way to hold them into the tweeter tower

Great tweeter nice clear crisp sound when highs hit you can hear the difference no popping worth every dime will recommend these to anybody looking for quality speakers

Crisp and Clear

Written By Tom L, Avon, CO on Wednesday, October 23, 2013

Crutchfield Customer Review (What's this?)

Since everything on my 4Runner stereo upgrade was a retro-fit, these tweeters were on par with the other components as far as install. I put them in the dash where the factory speakers had been, and modified the previous speaker structures to hold the new tweeters by tearing out the old paper cones and cutting the metal frames where the struts joined the magnets. The result was a perfect fit of the new tweeters, and a great high-end sound after the project was finished.

Pros: Great sound, reasonable install, very good price, adjustable sound direction.

Cons: None so far.

These Things Scream!

Written By Zack, Billerica, Massachusetts on Tuesday, October 01, 2013

Crutchfield Customer Review (What's this?)

WOW! These tweeters do work! I have them running off of the 25 watts per channel that my head unit has to offer and already they are really loud! I will be amplifying them with 50 watts per channel soon. Other than loudness, these look great. They have crystal clear quality, and are adjustable. You have no idea how much quality and fullness you are missing until you add a set of tweeters to your system. Well worth the price!

Pros: loud, clear, crisp, fills the car with great high end tones, can be used with little power, but will blow your mind with lots of it, look sexy, adjustable, flush or stealth mount, built in crossovers, competitive price

Cons: large crossover might be hard to route through certain areas, does not come with surface mount hardware, i cannot seem to find the limit as to how loud these tweeters will play.

You won!t regrest the buy

Pros: Best for price...

Factory upgrade

Written By Rod, San Bernardino, CA on Monday, June 10, 2013

Crutchfield Customer Review (What's this?)

I've been putting off upgrading my factory stereo system for quite some time and I finally came around to it, with these Alpine SPS-110TW, I already had purchased a pair of 6.5 Alpines. The first pair had a defect and I called the support line and they sent a replacement immediately. I love it... My next project is to upgrade the stereo and add an Amp to bring out the deep sounds. Doing it myself is great because it's self-satisfaction of doing it perfect with your Tech-line for assistance.

Pros: Able to take my time and do it right. It's simple, if you are willing to make modifications to your door panels.

Cons: None

great tweeters

Written By DannyT, Massachusetts on Thursday, June 06, 2013

Crutchfield Customer Review (What's this?)

I drive a '95 Volvo 850, and the tweeters that came standard in my dash stopped producing any noise at all. Naturally I wanted to replace them. I chose these because they were a good price and I was told they were easy to install. All I had to do was take the old tweeters out of the bracket and screw the new ones in using what they came with. There is tons of extra speaker wire so they're easy to install if you need to run all the wires too. They added the high notes my system was missing, and really brought everything together.

Pros: simplicity of installation, price, quality

dont waste your money

Crutchfield Customer Review (What's this?)

on my scond set it 3 months, thought i did something wrong on instalation, no just poorly designed, tabes brake off at speaker.

Pros: easy to mount and great sound when they worked

Cons: extremly poor design

Sound good, design poor

Written By robbie d's specialties, Tallahassee, FL on Thursday, November 22, 2012

Crutchfield Customer Review (What's this?)

The tweeters sound good. I have them powered by a JVC KD-AHD69 Head unit. Cutting holes in my Honda Accord door panels was easy. The bad: the back of the tweeter was held on by three rotating clips which broke off of one the tweeters. I could have mounted the speaker differently after the breakage, but I had already installed the other side. With the back broken, the rotating feature was to be eliminated. I had to by Epoxy to seal the back to the super strong spring on the back of the tweeter and hope that noone plays with the speaker. Other than that, they are up to Alpine's sound quality standards.

Pros: Swival feature/rotating angle for sound balancing is a great plus

Cons: poorly designed plastic covers on the back of the tweeter

Very good tweeters

Written By Doug, Golden, Colorado on Tuesday, November 13, 2012

Crutchfield Customer Review (What's this?)

These tweeters rock! They have great sound at high volume and the included in-line crossover eliminates the possibility of distortion.

Pros: Clear, loud high-frequency sound. Awesome hi-hats and cymbals.

Cons: None

Very nice

Written By Matt g, Ferriday Louisiana on Wednesday, October 03, 2012

Tweeters sound great in my extended cab truck. I am very satisfied with them. I would highly recommend them.

Pros: Great sound. Good power handling

Cons: None so far.
