Our take on the Kicker 40CSS654

by John Pollard
Kicker

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

It's time for an upgrade

Upgrading the old factory speakers in your car will give you a huge bump in sound quality, and Kicker designed CS Series speakers to get your sound system rockin' without breaking the bank. You'll enjoy your music even more when you hear all the details that your muddy-sounding factory speakers couldn't begin to reproduce.  

Bring on the treble and the bass

Kicker's 40CSS654 component speaker set provides low end from a tough 6-1/2" polypropylene woofer, with a polyester foam surround that will stay strong for years to come. The separate 3/4" titanium dome tweeter takes care of the vocal and instrumental details that'll really bring your music to life. The outboard crossover network allows you to pick from three different tweeter level settings so you'll get balanced sound wherever you're sitting. Grilles are included.

Features

Polypropylene Woofer Cones: The Kicker CS-series speakers feature durable polypropylene woofer cones, resistant to the moisture and temperature extremes found in automotive applications.

Ribbed Polyester Foam Surrounds: The ribbed polyester foam surrounds allow extended cone excursion for additional bass output and higher SPL.

Tweeter Mounting Options: The tweeters come with brackets to allow multiple mounting configurations: flush-mounted, angled flush-mounted (approximately 10°), and angled surface-mounted (approximately 15°).

Tweeter Dimensions:

  Flush Mount Angled Flush Mount Angled Surface Mount
Mounting Height 0.238" 0.563" 1.272"
Depth 0.532" 0.612" 0.554" (screw depth)
Frame Diameter 1.976" 1.976" N/A
Cutout Diameter 1.57" 1.587" N/A
Frame Width N/A N/A 1.688"
Frame Length N/A N/A 1.897"

Crossovers: The component system includes passive 2-way crossover networks for a seamless transition between the woofers and tweeters. The slope is 12dB per octave (both high pass and low pass) and the crossover point is 4000 Hz. A switch on each crossover allows you to set the tweeter output; 0 dB, +3 dB, or +6 dB. The crossovers' input and output wires are attached; the woofer output has quick slide terminals that connect directly to the woofer and the tweeter output has bullet terminals that mate to the terminals on the tweeter wires. The crossovers' dimensions are:

  • Length: 4.595"
  • Width: 2.463"
  • Height: 1.004"

Woofer Mounting: In addition to fitting standard 6-1/2 and 4-hole 6-1/2 applications, the woofer also has a standard 6-3/4 bolt pattern. However, if mounted in a 6-3/4 location the holes for the smaller pattern create an air leak, which must be sealed using a speaker baffle, or something similar.

Great Sound, easy to install
Pros:
Installation was a breeze. I am very happy with the speakers.
Cons:
My Truck already had a high end stereo with tweeters installed in the doors so I didn't need the crossovers so they sit in the box and I don't know what to do with them.

Had standard Kicker speakers in all 4 doors of my truck but sound wasnt quite right. I upgraded to the components after an easy installation thanks to Crutchfield's kit. The sound quality has improved greatly. At higher volume there is no distortion. I am very happy with the crisp sound.

Great sound, easy installation

Better than stock

Written By Laura, Fort Wayne, IN on Thursday, April 24, 2014
Crutchfield Customer Review (What's this?)
 
I just want to confess that I'm giving these speakers 4 stars because I haven't had them long enough to really break them in. I chose them for several reasons: Sensitivity rating, frequency response range and customer rating. Definitely notice the higher sensitivity rating. They overpower my rear speakers. They have nice highs. I can't say that I find them to be super clear like some reviewers have mentioned. I do appreciate great speakers (my last vehicle had Infinity Kappas), Can't say that these match that quality, but I'm not disappointed. As far as other ratings, people like what they like. These are good for the money and were fairly simple to install. I was able to fit the tweeters in the door using the old bracket but I'm hearing a little vibration so i will have to cut out holes and use the parts included in the box. The woofers actually will fit using the bracket for the stock speakers, you just have to be a bit creative. I left the bracket riveted in and used my dremel to cut out the old speaker. These woofers fit right in and you just need to pre-drill some small holes to screw into the plastic edge. Since we're talking about woofers, I'll add that the low frequencies aren't that impressive. I can't wait to put my sub in. I don't set my amp/subwoofer up to a ridiculous level - just enough to totally round out the low end. It's definitely needed with these speakers.
Pros:
Great price. Frequency response is pretty good for this class of speaker and is noticeable. Nice looking.
Cons:
Weak low end. Nothing else, really.

Great mids and highs

Written By BenW, Rio Rancho, NM on Thursday, April 17, 2014
Crutchfield Customer Review (What's this?)
 
Great product, but needs to be complimented with some subs. Mids are clear, and the tweeter is almost too good. Without any subs, don't expect to get any of the lows from these.
Pros:
Great mids and highs
Cons:
No lows

Excellent Sound!

Written By MaxW, West Chester, PA on Friday, March 21, 2014
Crutchfield Customer Review (What's this?)
 
These speakers sound excellent! I drive a 2010 Civic Sedan and have the coaxial version of these in the back and the sound is great, but somewhat limited since I do not have an amp. I will be getting an amp to reach the high RMS rating of these. Bass is more than sufficient with a compact car. Installation was difficult for me... But if you have some electrical experience, it should be no problem.
Pros:
Great sound, great price, high RMS.
Cons:
Had to make my own mount for the tweeter. Complicated install for a novice, even with help from Crutchfield.

Ordered 2 pairs of these for my 2012 JEEP Wrangler JKU. I got them for the dash and roll bar i wanted them as an upgrade for my factory system but soon i found out that these are just way too much for my little factory HU which i knew when i ordered them. So i must either upgrade my HU or simply get a Line Output Converter which what i plan on doing.
Pros:
Great quality, crisp sound, easy install.
Cons:
none

Kicker win

Written By Anonymous, California on Saturday, March 01, 2014
Crutchfield Customer Review (What's this?)
 
Installed 2 sets of these in my '01 Jaguar XJ8 with an Alpine deck and 45wX4 amp and I'm very pleased. Good clean sound. These speakers have a very nice frequency response range. You don't really need a subwoofer unless you're a bass-head.
Pros:
Good sounding speakers for the price. Great frequency response. Good quality.
Cons:
Can't think of any cons other than the high level signal boost function on the cross-overs is excessive... Just switch it to the off position.

Great buy!!!!

Written By Terry, Albany, Ga on Friday, February 21, 2014
Crutchfield Customer Review (What's this?)
 
Just finished putting these in my 03 4runner today and man at the sound quality difference. You have to improvise a little when installing the tweeters but that is half the fun! They are running off of a pionner avh-x5500bhs head unit and they compliment each other nicely. They dont really handle the low end bass to well at high volumes but that can probably be fixed by adding an amp wich i will be doing later. My factory speakers, i thought they sounded ok, were really muddy sounding compared to these speakers. i also have the two way kickers installed in the back doors and they arent as loud but compliment one another pretty nicely. It is a highly recommended purchase!!!!
Pros:
Good quality, superb sound, straight forward install
Cons:
alot of wires that you have to tuck away and secure :)

Kicker speakers

Written By Steve M, Myrtle Beach SC on Sunday, December 29, 2013
Crutchfield Customer Review (What's this?)
 
I installed the Kicker speakers in my sons Honda S2000. I had to drill holes for the tweeter which I also installed in the doors. The installation went very easy and the sound they components produced was amazing. We had all ready install some pioneer coaxial speakers prior but we're never happy with the sound. I recommend theses speakers highly. I will be installing a set in my GTO next.
Pros:
High quality sound
Cons:
None they put a great package together with this speaker system.

I love Kicker.

Written By AlexW, Dover, DE on Tuesday, November 19, 2013
Crutchfield Customer Review (What's this?)
 
These match my rear 6x9's perfectly. Just enough punch. No distortion until higher levels (OEM HU). The Crossovers have enough amplification that 6db is too much and 3 might be a bit much. I set mine at 3db. The tweeters are mounted in my doors, in fact, that was the most difficult part of the install. The crossovers come with zipties, I wish they'd come with 3m double sided to stick under the panel, or the door. something. I ziptied jt to a harness for the time being. The woofer fit EXACTLY inside my OEM bracket, no cutting required( so no rattle).

As for the Sound

It hits every note from even a low range, stuff that a dedicated sub should be taking care of. I'll be using the HPF and LPF in a new HU later to isolate it. Running off a low power OEM HU they take care of everything AND more. I'll be doing a speaker amp later. Might take care of the high end distortion.

Would I buy them again?

Yes.
Pros:
OEM install, Price, Distortion free
Cons:
Lack of undersurface mount for tweeter, weatherproofing could be improved on tweeter/crossover connection.

Crutchfield Customer Review (What's this?)
 
I have the Kicker 40CSS684 and the Kicker 40CSS654 in my car. I cant hear the difference between them so this review stands for both.
Pros:
Easy to install. The wires from the crossover to the speakers have different connections so there is no way to mix them up. They put out a surprising amount of bass for their size. I still will put in subs anyway because im sure heavy bass through these will decrease their life. I listen to metal, rock, country, rap and electronic or dubstep and these speakers perform flawlessly in my opinion.
Cons:
The tweeters are a little loud even on the +0 setting on the crossover. There is no need for the other settings. Buy other crimp connections to connect to the input wire, the ones they give are useless. Needed to adjust the higher frequencies down in my equalizer because they were too high. That may just be my specific application though.

99 Civic Install

Written By Albus, Smithfield, VA on Tuesday, November 05, 2013
Crutchfield Customer Review (What's this?)
 
Front door panel install. The speakers installed right into the existing speaker locations with no adjustments required including the tweeters. I originally set the tweeter level too high but once I lowered it, it sounded fantastic. Not real low bass response but I have these paired with the Kicker KS69 speakers and they more than take care of bass response. Paired together is fabulous. Couldn't be happier.
Pros:
Fantastic sound, easy install.
Cons:
Unfortunately Crutchfield did not send the bracket that was supposed to be needed for the install. Turns out that I didn't need it but would have been disappointed if I had.

This component setup didnt sound good to me in my 13 Wrangler. I guess because the woofer is pointed down and also to far from the tweeter so I ended up putting my kicker 3 ways back in the dash however I'm still using these tweeters as they don't sound to bad. Also the adapter plates didn't work for me so I just drilled new holes and mounted them.

Crutchfield Customer Review (What's this?)
 
These speakers are excellent. They have very good mid and low mid. I used them as the rear speakers in my expedition. They fill the gap in sound between my higher frequencies and the low bass beautifully. They also handle high sound levels with ease. Great speakers for the money. Go well with the qs line in the front.
Pros:
Value for the money. Great low mid sound. easy install.
Cons:

What a difference these speakers make. Dropped them in a two-seat convertible and can feel the air being pushed out. Makes buying a sub, for me, obsolete. they have more power than I will ever need. Great sound without distortion.

Love it

Crutchfield Customer Review (What's this?)
 
Great upgrade to factory speakers in 2013 Jeep Wrangler Unlimited Freedom Edition (really, cheap speakers in a $35k car?!). Sound better even than the matching 2 way 6.5" Kickers from the same CS series but which are half the price. Paired it with a small Alpine 45 x4 watt RMS amp so can't hear how loud they can go but no complaints here. Seem to have a little better low end that Polks which I have used in the past, which seem to have a high bias. The Crutchfield speaker adapter brackets are exactly what I needed, and the Mastersheets are SO useful!
Pros:
worth it unless you're willing to spend the money for competition level gear, like I once did back in 1996
Cons:
the only con I had was how relatively hard it is to get to the front dash speakers in my Jeep compared to most cars I've worked on; I'm not a super fan of tweeters up high as I don't like too much treble but that's the factory location - but the Kickers have a 3 position gain for the tweeters right on the crossover module!
