Excellent Value

Very surprised at how these 6.75" components sound with only 50 watts RMS to each speaker. Excellent value for what they cost.

Kicker KSS670

When installing this in a 2024 Toyota Corolla you need to purchase the adapter for the tweeters and modify it. There are four wires. Two come from the stereo, two go to the door speakers. I had to modify the harness to accommodate the crossover. Ideally this adapter should be shipped or offered as an option. To make it more complex, the wire colors from to the door do not match color schemes.

Great solid sound. I power it with Infinity 475a amp. 75w per channel. The crossover was small enough to fit in the kick panel.

Good set overall. Didn't produce as much bass as I had hoped, but still good. I'm driving them with a kicker key 200.4 in the front doors of a 2024 Honda Accord EX-L.

Real deal

Love the silk dome tweeter. Works as a great multi-step upgrade from factory. Would have loved to add just a little more power but the sensitivity is excellent and really efficient. Plus, I wanted a cost-conscious DSP/amp combo so Kicker Key paired great and feeds them 50 clean watts RMS. Works well in '22 Ford Explorer no B&O. Plus the install info is indispensable! Can't beat Crutchfield's directions and harnesses for DIY and even custom installs. And their service answered all of my questions along the way, including other areas of my system. Best service in the business IMHO.

Excellent Sound and Low Range

I had previously installed a great set of 6-3/4 inch speakers but wanted more bass. These fit perfectly in the door on my 2015 VW EOS Final Edition using the Metra 82-9010 speaker brackets and provide all the bass I was looking for. The tweeters are clear as can be without being harsh. Installation was a challenge as I wanted to use the existing sail panels for the tweeters to maintain a factory look and not block the defrost vents or drill through the A pillars.

Clear highs, great bass!

Don't let anyone tell you that a 6.75 doesn't fit where a 5.25 came stock. I got these in the front doors of my 2006 CRV and all I've got to say is They fit! & these definitely sound good. I've got them hooked up to a JVC 660BT and they just get clearer and louder when played loudly, they want more power. I matched them with the 6.75 2-ways in the back doors and this is a great setup. It's a shame Crutchfield doesn't sell them anymore. I didn't need the extra speaker mounts and utilized the mounts that came in the box. A little word to the wise, install some sound deadening in your doors and door panels while installing aftermarket speakers. Take your time and find everything that might rattle in your doors. Tighten all the bolts and screws your find along the way. Hit up Harbor F or add on a set of panel removal tools to your purchase to make the install easier, trust me that you'll use these tools again somewhere else.

Best speakers for the money!

This is my 6th set of kicker KS series speakers and they never disappoint!! The tweeters are not overly bright (which I prefer) but yet they are super smooth!!! In my opinion, they are on par with AudioFrog for a third of the price!! Buy them you won't regret it!!

sound decent. lots of options to make them work

I have these in front and back of my SLK32. The tweeters don't fit in the stock housing but I think I will move to a trim piece by rearview mirror. the mounting brackets included rock. they are beefy and can handle some dynamic stress for installs with fabrication. The schoshe will work but dont have the meat to suffer the pressure of some installs

These were supposed to fit into my Honda civic but the trim rings for the tweeters are not wide enough to cover the holes completely. Aesthetically note pleasing but they have good mid and high sound. You definitely need an Amp to get bass out of them

Kicker KSS670

These are great speaker and upon installation they definitely sound clearer and in my case a little bit louder. The only thing is that I know they would sound better with an aftermarket amp. Also the bass is good but lacking for my taste. Other than that no complaints. The install simple and easy. The customer service from Crutchfield is great and my experience with them has now given me the confidence to install amp and subwoofer.

These sound great in my Honda Ridgeline. The tweeters fit in the existing housing but needed to be stabilized with adhesive. The crossovers for the tweeters were a bear to get into the pillars. If I did this again, I'd get tweeters with built-in filtering to avoid having to place the crossover box.

2017 Tundra - Kicker 6 1/2" speaker installationss

These speakers appear well built and installed relatively straightforward. Biggest challenge is finding a location to install the 4ea. crossover units tied to each speaker. I installed 4ea. of these speakers on my 2017 Tundra Limited Double Cab at each door. Drilling into the door in necessary to attach each crossover unit and suggest making a hole template beforehand to mark the drill holes is highly recommended. Only main issue is that I needed to install spacers for the front door speakers/adaptor plate so the back of the speakers don't rub on the door window steel channel assembly as these speakers are deeper than the stock (non-JBL) OEM speakers (see attached pictures). [Note: I also installed Kicker speakers in the Front Center (3 1/2" - no picture/Corners (Tweeter pictures shown)] Crutchfield did forget to provide the rear speaker adaptors that are required, but they promptly are sending this at no cost. And their online tech support is excellent - as always! Much appreciated.

Sound great, definitely more low end than thr stock speakers. But, seeing the size of the stock magnets compared to these it's obvious. Tweeter install was a bit more involved than I was used to but sometimes you habe to pay to play.

Great if an easy install is a priority

These are really good, very loud speakers however I found the mids needed the high pass set around 150-200HZ. Also they loose some detail when there's lots of competing high frequencies - sounds great if there is not an over representation in the high frequency range. They sound better then the "compare the sound" feature but you can hear the loss of high frequency details on some of the sample tracks. I've say these are 4 star speakers however they get an extra star for being a really easy install: the crossover is small and light so one can plug stock wiring into the crossover and then be velcroed (with industrial strength verlcro) to the door. Also the the crossover comes pre-wired with connectors that plug right into the speakers so extra crimping or cutting of terminal required on these which is a huge bonus. I'd say a sub-woffer is pretty much mandatory, sounded really good with a kicker sub-box.

Clean and Powerful

I installed 2 pairs of the Kicker 47KSS6704 speakers in my Honda CRV as part of a complete sound system replacement. These deliver smooth, clean highs and tight, punchy mids & mid-bass. I can push them hard in terms of SPL, and the sound does not degrade. The passive crossovers can be a bit tricky to install in the doors, but I was able to find an acceptable placement without much modification. Overall, I'm thoroughly satisfied with this purchase.

Great buy - very crisp and clear

Great set of speakers. Bought both the 6 3/4 components for front and 6 1/2 coaxials for the rear for my 2020 Subaru WRX STI. The brackets were frustrating at first since it was advertised "no drilling required", but once committed to modifying the brackets and drill into the door, it was much smoother. Have a 75w RMS 4-channel running this set and it's plenty loud. Very crisp and clear. I used sound deadening behind the speakers, speaker gasket between door/bracket and bracket/speaker, and used roadkill surround to keep waves from getting trapped in between door panel and door. The K-Series speakers are above average in the "mid class" speakers (between c- and q- series). Very happy with the set up and would highly recommend - and take the extra time to run new door speakers from the amp and add sound deadening. Both are a must if you want a true upgraded mids/highs system!

Save your pennies.

First, I'm not a "Audio File" but the sound of these are just ok. My .02 cents is get the best speakers you can afford, I think speakers biggest difference? Second, I care more about the sound coming from under hood & out the tailpipe/s. I purchased a mint condition older Tacoma Reg. cab & a friend is a GM for a Toyota performance shop. I told him what I found & sent photos! His first words were "I want it!" The shop is working w/ a supercharger co. on a new system. The supercharger ended up in the truck. So now I was able to upgrade many other things to make a little sleeper. My stereo installer wanted to add deader/weight to the doors, no way! The stereo system goes in w/ a small amp, small self powered sub mounted solid to the back of the cab & these in the doors. Sounds a lot better than stock but my installer KEEPS insisting we need to add sound deader. So I cave in, the sound is better after adding the weight/sound deadening to the doors. He then sends photos and the promo videos the performance shop made of the Tacoma to a speaker manufacturer & asks for a little sponsorship. He gets a sweet deal on some really GREAT speakers. Then changes the speakers. OH MY GOD what a difference I could NOT believe the difference? Can't see the speakers behind the door panels but here's a interior photo.

Very easy installation. The supplied adaptors worked perfectly although the screws were a little long for my application in a 2007 Jaguar X-Type sedan. Only modification required was cutting a 1 1/4" hole in the door panel to mount the tweeter. Time to rockin' into the night!

Great Sounding Speakers

This component system was installed in a 2018 Jeep Wrangler JL dash, it took the entire day. The sound is fantastic, however, not louder than the factory speakers in the soundbar which are different ohms. The instructions from Crutchfield were easy to follow, just very time consuming since you need to remove just about everything from the front dash. With the larger woofers, I also had to replace the speaker pods. I also used different tweeter holders, than the ones provided by Crutchfield (they did not include any holes for the tweeters). The woofers are solid and product a good amount of bass, the tweeters sound decent, however I encountered issues with the cross-over. The tweeters would not work with the cross-over plugged into the knee panel, but they did work with the cross-over plugged into the dashboard corners. The cross-overs are mounted within each knee panel pod, the wire come down from the speaker dash, to the cross-over, and then back up to the tweeter. The woofers are just plugged directly into the knee panel without a cross-over and still sound great. Note: I did not install any external amps, and the sound still has the capability to be very loud.

Fantastic sound

The speakers sound fantastic so far. I have a 75x4 amp hooked up with 2 channels going to each of these. Being a new set up, I only have the amp turned up about half way, but they sound really good. I should have invested in Dynamat though. I'll have to add that at some point. Even at halfway, the bass is definitely there.

Kicker was not messing around with these!

These speakers are LOUD. I paired them with a Sound Ordinance amp that pushes 110wats RMS and I wish I had a camera to capture the smile on my face when I heard what these suckers could do! I still plan on having a professional check the tuning on my amp but so far everything is clear and incredible. Go ahead and get them, you won't be unsatisfied!

Effiecient power, sloppy accuracy.

These kickers do get loud, they have no problem having a powerful amplifier behind them. But they're not accurate and they need a lot of tuning. If left untuned it leaves a harsh shrill in your ears after every listening session. It's sensitivity is great but not if it's full of peaks and nulls. The accessories come in the box are very helpful. The tweeters fit in many locations and the crossovers are nice and slim. But if you're looking for quality, this is not for you. If you're looking for a minor upgrade over your stock oem speakers without breaking the bank? Yeah, these ones should do alright. Just don't expect anything more and you'll be fine.

Crisp and clear!

I installed this set in my 09 PT Cruiser, replacing some older Alpine SPS610 coaxes. I decided to do a full active front stage, so I wired these to a Kicker Key 180.4, which obviates the need for the crossovers. The crossovers are very compact, so if that's how you're gonna install the set, you'll have no problem fitting them. I also have a Kicker Key 500.1 and a 10" Prime series Rockford Fosgate sub. These are great as the front stage, phenomenal with a subwoofer. My head unit is a Kenwood Excelon KDC-X303. These sound really good no matter the source. GREAT for rock and metal, but sound excellent with jazz and classical as well.

Bought them for my son's Toyota Tundra to fit in lower front doors. Running them active with ~ 90 watts per channel. They sound great, loud and clear. You do need to give them some power.

Great Speaker Set

Great sounding speaker set. A tremendous upgrade from factory. I replaced all of the speakers in the doors of my 2020 Kona (non-Infinity) with these KS Components. It was like someone literally took heavy blankets off of my cars sound. They have incredible bass response and sparkling clear highs. I paired my KS sets with a 12" Q-Class L7 sub being pushed by a Kicker KX 1200 watt amp and they hold their own perfectly while being pushed by only the factory head. They have solid construction and nice heavy magnets. I can't say enough about how much I love these speakers. Well worth the money and I plan on replacing the speakers in my wife's 2019 Tucson with these.
