Alpine combines outstanding materials with superior construction to create their Type-S Series speakers. Upgrade your factory speakers with these Alpines, and they'll fill your vehicle with high-fidelity sound at a reasonable cost.

The SPS-406 4"x6" speakers use strong, lightweight polypropylene-mica woofers to handle the lower frequencies. Air-injected rubber surrounds keep cone movement under tight control, eliminating distortion and enhancing bass. Stamped steel frames provide rugged support for these speakers, and their low profile allows them to fit in more factory locations.

The 3/4" silk dome tweeters play your high notes smoothly and comfortably with no hint of harshness. You can also swivel the tweeters up to 10 degrees to improve the stereo image at your listening position. These efficient Type-S speakers will sound great with a low-powered factory radio, but they're also made to handle the high power output of an external amplifier. Grilles are not included — factory grilles are appropriate for most installations.

A little too bright February-04-12
Reviewer: clayr from wilmington, nc  
OK - as far as installation, no one beats Crutchfield - great directions, fast deliver, they rock.  

Speakers - i bought because i trust the Alpine brand, but i was disappointed, if only from a perspective of how these speakers are presented for use.  I bought them (along with a set of Kickers) to replace the stock speakers in my 2003 Silverado, set up with a Kenwood Excelon KDC-395. They were listed as replacements for the rear door 4x6 speakers. After the install they sound very clean, and very bright - but TOO BRIGHT. no matter how i adjusted the head unit, i could not get any low end from the speakers.  So i decided i really needed 6x9's, even if i have to cut the door panel.  I felt a little bad returning them, until i re-installed the stock speakers to hold me over, and they stock speakers have more low end - sounded BETTER - than these.  I think they are good speakers, but better suited for a front door setup, not the rear where you need some bottom end. (I put the same head unit in my daughters car with 6x9's in the back and there is PLENTY of bottom end - even without an amp and subs).  

so that's my comments - might work well in some setup, but not as the rear speakers.  Get out your metal cutter and put those 6x9's in.


 
Awesome August-29-11
Reviewer: Chris from Danbury, CT  
I installed this myself in the dash of my 2001 s-10 Zr2. Everything said they won't fit in stock spots without modifications. I plugged them in to my factory wiring with the wiring adapter that was included n with no modifications they fit tightly . They sound awesome along with the alpine cda-105 headunit, and the alpine SPS-600C Type-S 6-3/4" component speakers n tweeters Rock out clear n great. Cannot wait to add my jvc arsenal 10" sub! These speakers way surpassed my expectations for $79.99!!!!!!!!!


 
porsche 944 August-20-11
Reviewer: mike from Totowa nj  
First of all I want to say that I love dealing with Crutchfield!  They're always very  helpful when you have problems!   I really like these speakers a lot!  They sound great with my JVC BonJiovi  powered stereo!  Crisp and clear! Especially for only being a two way speaker!   There might be better speakers out there than these but they wouldn't fit in the  front doors of my car. Trust me..  The price of these is very very low for the quality  of the sound!   Not a ton of bass but there's no way of getting that from a 4by6!    

The front speakers just barely fit in and the grill is bulging out  just a  little bit.  But in the rear I could have gone with something a little bigger magnet  wise... but still stay with a 4 by 6.  The hardest part of the rear install was pulling  the vinyl apart without tearing it! (fingertip strength)  The rest is really not that  hard!  I built up the rear footwell with a lot of layers of foam so that I could sit back  there and work!

Reviewer: Adam from Tulsa Ok  
Replaced my stock 4x6 speakers in my 03 ext cab silverado.  Huge improvement,
clarity and range of music are the biggest changes.  Install was easy although
the speaker installation instructions are lacking.  Crutchfield instructions
included helped out with proper and simple door removal.  Overall very
satisfied.  Still running them on the stock stereo, power handling dictates
turning the volume up a little more than before with stock speakers.  Love the
sound, very good alpine speakers.

2002 cavalier August-21-10
Reviewer: Tyler from Abington Pa  
To start off i just bought a 2002 cavalier, and i wanted to upgrade my audio system. So I got a full system. I got a Kenwood Excelon KDC-X494 headunit, these  4x6 sps alpine speakers for the doors, 6x9 sps speakers for the rear, Kenwood KAC-6404 4 chan amp for the speakers, a jh600 mtx mono block amp, and a JL Audio 12W3v3-4 subwoofer.    

I also put bass blockers to these speakers because thats what my subwoofer is for.  I did test the bass before adding the blockers, and it was fine for a 4x6, but not great. I will say however the mids and highs sounded great with my amp. I would suggest these to anyone building a system. They make my music sound full and lively.
