You jump in your ride and turn on your favorite song — you're straining to hear the snare drum, but it's still just barely audible. And that dull, fuzzy-sounding bass guitar is just about breaking your heart. Pioneer TS-A Series speakers bring your music back into focus with precise, superior reproduction of instruments and vocals, so all those details you love will really pop.

Pioneer's TS-A4674R 3-way speakers feature 4x6" woofers with stiff Aramid-reinforced polypropylene cones that ensure clarity in your music's bass and percussion. Highly elastic polymer surrounds help keep cone movement under control, for smooth, tight bass. The 1-5/8" cones fill in all the midrange details for lush vocals and crisp instruments.

Soft dome tweeters deliver warm, dimensional treble, so you'll hear all the overtones that give your music ambiance. The built-in crossovers ensure that the right frequencies go to the tweeter, midrange, and woofer, so your music sounds natural, just as the artist intended.

  • 4x6" 3-way car speakers (pair)

Product Research


Woofers: Each speaker features an IMPP (Injection Molded Polypropylene) cone woofer interlaced with carbon graphite and long aramid fibers and a 4.4-ounce strontium ferrite magnet. This IMPP cone design provides the strength and rigidity that powerful bass requires. The high-density, compressed internal architecture is resilient and transfers sound very quickly. The result is full-bodied, rich sound.

Surrounds: For durability and a smooth response, each woofer uses an elastic polymer surround.

Midranges: Each speaker has a 1-5/8" polyester fiber cone midrange for accurate response with low distortion. The midranges have 0.1 ounce neodymium magnets.

Tweeters: Each speaker uses a 3/8" dome tweeter made from PET (Polyethylene Terephthalate) film for crisp, clear highs.

nice speaker to add to your car

Written By Ed H, Elkhart, IN on Friday, August 31, 2012

Crutchfield Customer Review (What's this?)

Nice bass response for a little speaker hooked up easily in the door panel

Pros: Nice sound out of the factory stereo with these added in the front door panel

Good sound

Written By CraigJ, Troy, IL. on Wednesday, August 08, 2012

Crutchfield Customer Review (What's this?)

These speakers were a definite upgrade over the factory speakers in my 03 Silverado. They have good, clear mid and high range sound. Low range could be better, but not bad considering the size of these speakers and it is still better than the stock speakers. Speaker options in the extended cab Silverado are pretty limited, so I'll probably be adding a powered sub in the near future to round out the sound. Install was a breeze with the provided Crutchfield instructions and wiring adapters.

Pros: Good sound and easy install

Cons: Bass is only OK

Good sound, easy installation

Written By DW888, Fresno, CA on Saturday, July 07, 2012

Crutchfield Customer Review (What's this?)

I bought these speakers to replace the stock ones (that had finally begun to give out after 22 yrs. of use) in my Chevy truck. For the price, the Pioneer speakers are really good, a definite step up from stock speakers. Also, Crutchfield helped make the install really easy; the master sheet makes it nearly impossible to mess up. A very good product.

Pros: Sound quality/range. Fits into preexisting speaker mounts. Very easy install.

Cons: Lack of a cloth covering for the speakers.

1999 Blazer 4 door

Written By Michael, Lee's Summit, MO on Friday, June 01, 2012

I picked these up to go along with my new Sony head unit and they kick something serious!! Love the highs and mids that these little guys put out, the bass is on par with expectations being that they are 4 X 6 speakers. They fit right into the existing dash location on my Blazer the only thing I had to do was cut the factory crossover off since the dash speakers in the Blazer are just small tweeters... Once I did that they really poured on the sound! The Sony head unit I have has built in BT for phones and these speakers reproduce the voice of the caller perfect, as a matter of fact I had to set the caller volume pretty low because these just really kill the factory set-up.

Pros: Great speaker with nice loud clear sound. Minimal distortion and will bolt right into most GM 4 X 6 speaker locations. Price is right!

Cons: None so far

Good Speakers

Good speakers for the price, and fit well into the dash of my Jeep. Sounds good with the top down.

Crutchfield Customer Review (What's this?)

I bought a 1990 chevy pickup and the stereo didn't have any bass coming out of the speakers. I tried everything. I finally decided on some TS-A467R4"X6" because I had Pioneer speakers before and they were great. I also knew these would bolt right in. The difference was night and day! What a great sound. The bass is incredible and the mids and highs are nice and crisp. A fantastic product.

Pros: Great sound. Installation was a breeze. The directions were straight forward and easy to understand.

Cons: NONE

Pioneer TS-A4674R

Written By RO, Portland, OR on Wednesday, February 22, 2012

Crutchfield Customer Review (What's this?)

Great improvement over the factory dash speakers in my 1992 Chevy Suburban. Great fit without modification. Could use some type of cloth for under the factory speaker grills to protect the speakers from sun exposure on a dash mounted installation.

Pros: Great fit without modification. Great sound improvement over the factory original speakers.

Cons: Could use some type of cloth for under the factory grills to protect the speakers from sun exposure on a dash mouted installation.

Nice Speakers

Written By John, San Ysidro, CA on Friday, December 30, 2011

These speakers are a serious upgrade from the stock paper speakers. They have a really nice sound. They go together great with my son's Kenwood x-395 stereo.

Pros: These speakers fit perfectly in my son's 89 Camaro.

Awesome sound

Written By Dr. Bill, Thunder Bay Ontario on Thursday, December 29, 2011

Put a pair of these in my son's 2003 Sonoma. Crutchfield says they won't fit in the dash but all it takes is a little trimming of the mounting lugs on the factory speaker grilles to compensate for the extra thickness of the Pioneers. The improvement in sound over the factory speakers is phenomenal!

Pros: Great sound.

Cons: Nothing to dislike

Pros: It fits and plays clear.

Cons: No speaker covers!

Nice speakers, great fit!

Written By Al, Colorado on Friday, September 09, 2011

Crutchfield Customer Review (What's this?)

I installed these in my daughter's 1991 Camaro. Crutchfield's info on maximum depth was CRITICALLY important in making this install work. There is very little mounting depth and the info from Crutchfield's website saved me returns and headaches. I LOVE the fitment info. The speakers sound great, and do their job very well. The mounting plates took some fiddling and I used fender washers over the screws to secure the plates and speakers, but it worked fine. The daughter is happy and I'm happy.

Crutchfield Customer Review (What's this?)

I got these the same day as my L3 sub, and what a great combo. These two speakers fit in my factor dash speaker holes without a problem. Sounds great with or without the sub. Very clean, crisp, and clear high notes. They make you feel like your right there. Can't complain. Also came with factory wire harness so no guess or cutting wires. Just plug and play. Thank You Crutchfield!

Crutchfield Customer Review (What's this?)

I've owned several sets of Pioneer speakers & I've never been disappointed by them. For the money you get a well built set of speakers that will likely outlast your car if treated properly. I was very impressed with the bass response of these speakers, they reproduce the low end on par with many 6x9"s I've listened to. These speakers really shine in the midrange & high end of the spectrum though & are an excellent choice to pair with a set of <500W subs so you can actually hear something besides bass thumping when you turn up the volume.

Written By Mark L, Canajoharie, NY on Wednesday, May 04, 2011

Put these in the rear doors of my 2007 Siverado ext cab. You will need to drill
four holes for each speaker but the whole job only took 40 minutes. Not bad for
the price. These speakers are much better than the factory speakers.

gmc sierra

Written By bill, md on Monday, February 21, 2011

Crutchfield Customer Review (What's this?)

I gave these a 3 because they didn't come with mounting hardware. Crutchfield
told me everything for my GMC Sierra application but the mounting hardware not
included with these speakers. I had to stop my install and go to the store for 8
They sound great!

Get everything you’ll need to enjoy your new Pioneer TS-A4674R

Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
You'll need speaker wire to connect your speakers to your amp.
Keep your speakers clean and dry. They compress to fit behind your speakers.
These speaker connectors are handy if you're running new speaker wire or if your speakers have oversized terminals.
The right tools will help keep your installation simple and clean.
If your stereo doesn't cut the deep bass from your full-range speakers, a set of bass blockers can help prevent distortion and give you cleaner bass too.
