You put some good bass in your car, but now your speakers just aren't hanging with your subs. Kicker designed their KS Series speakers to deliver the performance you need to bring that "live music" experience to your ride.

The KS525 5-1/4" 2-way speakers use heavy-duty polypropylene cones supported by Santoprene rubber surrounds. These speakers can handle high-level playback without straining, especially when they're powered by an outboard amplifier. Each speaker sports a titanium 3/4" dome tweeter that broadcasts plenty of high-frequency sparkle, so you'll hear all the sonic details that make your tunes exciting.

Product Highlights:

  • 2-way 5-1/4" speakers (pair)
  • polypropylene woofer cone with Santoprene™ surround
  • 3/4" titanium dome tweeter
  • power range: 6-45 watts RMS (135 watts peak power)
  • frequency response: 45-21,000 Hz
  • sensitivity: 90 dB
  • top-mount depth: 2"
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Kicker KS525...BRILLIANT

Written By WarrenW, New Jersey on Friday, March 28, 2014

I put these in the dash of my 99 Wrangler using custom 5.25 speaker brackets (I think Crutchfield sells a bracket as well)...sound very nice and clear working off aftermarket HU, mids and highs are clear, (mine is Alpine 143BT)...then I picked up the Alpine Power pack which gives you 45 watts rms per channel (plug and play, alpine also offers a universal one for none alpine HU)...BRILLIANT!!! They came alive...these are by far the best 5.25 speakers I've ever owned! The clarity is simply amazing! would highly recommend these to ANYONE 2 of my friends have them now and agree with me 100% MUST BUY!

Pros: Cant be beat for the price sounds amazing with or without an amp

Cons: none that I can think of

Crutchfield Customer Review (What's this?)

I was somewhat disappointed to see that these where smaller than what I was replacing but as soon as I hooked them up all my fears disappeared these things have tons of base and get loud enough to wake the block up and im not even using a amp yet

Pros: Great door speakers they will not disappoint

Cons: Install took alot of improvising even though they where suppose to fit my car but that's not the products fault its Crutchfield

great kickers

Written By Anonymous, suwanee, ga on Thursday, February 06, 2014

Crutchfield Customer Review (What's this?)

I originally purchased these to go in the front doors of my 05 ram1500, I didn't like the sound. So I switched them to go in the rear doors and they sound way better. I added some Polk 6x9s for the front doors and the truck sounds great.

Pros: good highs, decent mid

Cons: No bass at all

Big bang for the buck!

Great speakers for the price. Perfect fit in my Sahara and the volume will rattle your fillings!

Pros: Everything!

Cons: Nothing!

Less highs and a little more bass

Written By Julio, Lynchburg, VA on Wednesday, December 04, 2013

I installed References Infinities in the front of my cars, and despite their beautiful sound, I thought they were a little bit too bright; so I've got these Kickers for the back and I'm very happy with their bass response; creating a pretty well balanced sound system in my car

Pros: They sound really good.

Cons: They need a little more voltage than my infinities; so I went for an Alpine 4 channels amp to drive my sub and these two kickers. Now the overall sound quality improved noticeably.

Great

Great product for the price! I added a 5 channel amp and 2 10" subwoofers to complete the package.

Pros: Great value.

Cons: None.

Good value

Written By Bcbowlan, Shawnee, OK on Wednesday, August 21, 2013

Crutchfield Customer Review (What's this?)

Good sounding speaker for the price. These would compliment a sub very well. The reason I give 3 stars is the fact that one was blown from the factory and I had to replace it. However, Crutchfield handled the situation and exceeded my expectations in customer service by sending new ones right away.

Pros: Great value

Cons: Not much bass with stock stereo.

Great Speakers for Jeep Wrangler Roll Bar

Written By Josh, Vail, AZ on Monday, June 17, 2013

Crutchfield Customer Review (What's this?)

These speakers are the heart of my sound system. They fit perfectly in a 1997 Jeep Wrangler and sound great. I installed with bass blockers to send the bass to my powered subwoofer (Kicker 11PT8) in the trunk.

Pros: Great sound Easy install

Cons: None

Beautiful Sound!!!

Written By Walker S., Blountstown, FL on Sunday, February 10, 2013

I installed a pair of these in the front doors of my 2002 Isuzu Rodeo a month ago and honey, they are incredible! Crisp, strong, BEAUTIFUL sound from these babies no matter what you listen to! The highs are sharp and sweet. The mids full and strong, and the bass surprisingly powerful, especially at slightly high volumes. Paired with my Polk Audio db651s set in the back doors and Power Acoustic 4" in the rear roof, I have the best full range of the entire high school! Definite recommending these!

Pros: Strong, full sound. Clarity even when turned up loud. Great price

Cons: Absolutely none!

Kicker KS525 - Crisp Responsive Sound

Written By RLK, Michigan on Tuesday, January 01, 2013

Crutchfield Customer Review (What's this?)

Crisp sound, very responsive. Easy installation using the Crutchfield Master Sheet, the Kicker provided speed clips and Chrysler wiring harness leads. Purchased these Kickers to replace the OEM rear speakers in 2000 Jeep Cherokee and plan to purchase a second set to upgrage the OEM door speakers too.

Pros: Crisp and responsive speakers

Cons: Light on bass tones

Love these speakers

Written By RickS, Louisville, KY on Saturday, December 15, 2012

Crutchfield Customer Review (What's this?)

I bought these to install in the doors of a 2004 Dodge Stratus. I installed them with 6.25" Kickers for the rear deck and a JBL amplified sub. These speakers are amazing. I got them for the vocals and highs as the sub handles the lows and the sound is extremely crisp and clear. Sounds like a concert hall! If you are looking for a great sounding speaker at a good price then get these. You won't be disappointed!!!

Pros: Awesome sound, great price

Cons: None

Speakers for my door...

Written By Anonymous, Hawaii on Thursday, November 01, 2012

Crutchfield Customer Review (What's this?)

Nice set of speakers, just what I needed at a great price... Came with everything to install but it didn't have a template to cut the holes... Wasn't to hard to work around that but it would have come in handy if they would have supplied one.

Pros: Nice up to date looking speakers at a great price.

Cons: No template to cut speakers holes

Pros: listening 2 my friends in his 99 buick regal sound damn good so I know my 98 regal will sound good also...these kickers are built tuff

Cons: none

Great Sound

Written By VABEACH01XJ, Virginia Beach on Thursday, September 27, 2012

Crutchfield Customer Review (What's this?)

These little speakers sound great for their size. I installed them in my daughters jeep to replace a much lower brand of speaker that sounded terrible. The difference is impressive. A sony head unit drives all 4 of them, front and rear. I would suggest adding a sub, as I have done to add to the highs. The bass boost will drive a little bass out of the 5 1/4, but it is not too good. These speakers combined with the sound ordinance powered sub enclosure add just enough high and low to create a well balanced sound stage. My daughter loves the sound of her new ride. Thanks for the continued support Crutchfield!

Pros: Great highs and mid-range. Sound quality is excellent.

Cons: Not really a con, but the bass is a little distorted, but that is normal with a 5 1/4.

Kicker

I bought some 4 inch kicker speakers for my 325i and they were great. I decided to purchase some 5 1/4 inch speakers for the kick panels and now I will be a kicker customer. I love them!!!

Pros: good base and mid power.

Cons: i do not see any cons at the moment!!

Factory replacement

Written By CJ, Ellenton, FL on Sunday, August 26, 2012

Crutchfield Customer Review (What's this?)

The speakers sound great and I can turn up the bass and they do not bottom out. They were easy to replace in the front doors of my Corolla.

Not What I Thought

Written By youbet211, Lynnwood, WA on Tuesday, August 07, 2012

Crutchfield Customer Review (What's this?)

Looking at previous reviews I thought these speakers would have a great sound, which they did in the upper voices, but there is no mid or bass at all. If you can, look at upgrading to mid-range speakers that have some bass with them.

Pros: Great highs

Cons: Ok mids, terrible bass. But nothing to expect much from 5 1/4 speakers.

Great Speakers

Written By Anonymous, Buffalo, NY on Wednesday, April 11, 2012

I have 2 pairs of these in my 2000 Jeep Cherokee. Much greater sound than the stock speakers. They produce great mid's and treble but the bass is only alright. All-in-all these are a great pair of speakers that give a great sound.

Pros: Great mid's and treble

Cons: The bass produced was OK, took some jury-rigging to fit into my front doors

Great Speakers

Written By WaterDR, WI on Saturday, March 10, 2012

Crutchfield Customer Review (What's this?)

I just upgraded to these speakers in my sound bar from the Kicker DS525's. Why you may ask? Well, I figured out how to move the DS525's to my dash and wanted to try a better speaker in the sound bar on my Wrangler. The KS series is a really nice upgrade from the DS. Mids and high's are lot nicer! The DS speakers were fine, but I would certainly spend the few extra bucks to get these!

Pros: Strong, solid, great natural sound.

Cons: No bass....BUT...I don;'t see that as an issue. This is why they make subs. If you don't want a sub, then get a bigger speaker.

Great Sound

Written By trbonium@gmail.com, Charlotte, NC on Thursday, March 08, 2012

These speakers were easy to install. All the required brackets and special connectors for my Beetle were included. After install, with the doors open, the speakers sounded ok. But once we got in the car and closed the doors you could really hear the sound quality. Highs and lows are great. Only replaced the door speakers and now I'm wondering how great my system would sound if I replaced all my speakers with Kickers. Worth the money.

Pros: Easy install. Great price. Great sound.

Cons: Not gold plated and didn't make the car go faster.

Crutchfield Customer Review (What's this?)

These speakers definately play loud and clear! Don't be fooled by the size! l have them installed in all four doors of my compact SUV and it sounds just great. Just remember you will need a sub if you want to hear and feel any serious bass.

Written By Drew, San Francisco, CA on Monday, May 16, 2011

Gotta agree with the others in saying highs are great, mids are pretty good, but bass is lacking. So great speakers if you get a sub

Great Mids and Highs!

Written By Dr.S, Dalls, TX on Saturday, May 07, 2011

Crutchfield Customer Review (What's this?)

These speakers are AMAZING! I bought them for my classic Mercedes (install was fairly involved). I am running an old aftermarket Pioneer head unit and these babies sound fantastic. The mids are strong. The highs are super clear and crisp. I highly recommend these to anyone looking to add the top end of the sound spectrum. The only negative associated with them (and it's actually not even a negative at all), is that they don't put out very loud bass. They are only 5.25" though, that's not what they are designed for. I'll be adding some 6x9's in a custom box on my back dash for the lower end soon enough, but until I get to it, these speakers make the top half of the frequency spectrum sound so incredible that I'll be happy until then. Bass blockers would also probably be a good idea, as the bass they do put out seems to get in the way of what would otherwise be perfect sound.

Great Speakers!

Written By Josh, Oak Ridge, NC on Tuesday, April 26, 2011

These speakers are great! The only thing is, you will probably want to buy a subwoofer! The bass in these speakers is not strong, however the treble and mids are great!
FYI: If anybody owns a 1993 Dodge Spirit and wants to install these speakers in it, you can! The Crutchfield & other websites say the speakers will not fit, but they do!

Just ok nothing special, if your looking for a better speaker than the cheap factory speakers this will do the trick but if your looking for a better speaker for a high end systme this is NOT the ones you want.

Product reviews from the Crutchfield Labs

Crutchfield writer Jo knew her factory audio system wasn't cutting it...she needed a car audio intervention. So she decided to replace her factory speakers with Kicker, and power them with a Kicker...

What are the Labs?

Get everything you’ll need to enjoy your new Kicker KS525

Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
You may need speaker wire to connect your speakers to your amp or receiver.
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.
