Customer Ratings & Reviews

Everybit as good as the more well known products

This came free with a bundled purchase,.. and I also purchased some Rattletrap Extreme as this wasn't enough for the car. I was expecting this to be mostly unusable due to the Name.

I was wrong.. it was every bit as good in thickness and adhesion as the more expensive brand I had bought. So if you can get this cheaper than other Sound material,.. go for it.

NVX SDVK4

Works great at a great price. I have it under my trunk lid and it keeps it from rattling too bad.

Good product, not the easiest

Used a few sqft of this material, along with the equivalent from Streetwires (PartsExpress) and a ton of Peal 'n Seal (Lowe's) for the rest.

I would say that Peal 'n Seal was the easiest to apply, but also the thinnest (an cheapest). So if you are doing some serious job you may want to double or triple the layers.

The NVX material was the thicker of the three I used, and once it's glued it stays soft which is very good. But beware, you will never get it off again. The only thing I would reproach is that the aluminum is quite thick, which makes it hard sometimes to comply with shapes. But it is good to fill in big gaps or openings and add some rigidity.

My preferred material is the Streetwire stuff, which is a bit cheaper. It was thick enough and compliant enough to make it really easy to install and it sticks like crazy while being forgivable if you make a mistake.

Have fun!!!

awesome

simply amazing before i installed it i could not hear a clean bass at all by trunk was rattling so much but now my trunk is solid and i'm enjoying the bass it's cheap and awesome NVX for the win

NVX better than the Rest

Great price, great quality. Plus delievery came fast. Will buy again for rear door.

NVX SDVK4

I USED THIS PRODUCT TO INSULATE THE SHEETMENT AT THE KICKPANELS AND THE FLOOR AREA BEHIND MY REAR SEAT IN MY1972 VW SUPER BEETLE. THIS PRODUCT WORKED OUT GREAT FOR ME, NO VIBRATION, REALLY QUIETED THE ROAD NOISE ALSO. OVERALL A GREAT PRODUCT.

Great product!

This is the first sound dampening material that I've used so far and I have to say that I am quite impressed with the product. I used it to reduce the vibrations generated from my sub at the back of my car. Since then, sound quality has improved considerably. For the price, I strongly recommend this product.

awesome

this is the best stuff for the best price now

works great

Less weight than other sound proofing I have used, cuts easy and with a hair dryer it will mold to any contour .

Perfect kit foe speaker installs or a single door.

This deadener works wonders for vibration and outside noise. It is thicker than Dynamat and will eliminate that horrible resonance caused by lower frequency notes transferred through sheet metal and rattles in plastic. It also improves sound quality and SPL.

Didn't see a difference for my car.

I'm sure this may have different results for different cars. I simply bought this dampening kit to fix the rattle and keep in the sound. I'll give my list of pros and cons. I own a 2000 Honda Civic.
Pros: Installation is very easy. Simply peel and apply. It's recommended to have a roller to get in the cracks (which this kit does not come with). This kit does keep in sound. Outside the car you can barely hear the audio (in terms of actual music, not bass).
Cons: This con is pretty much based on the vehicle I have. The mat did not fix my rattling problem. I placed it everywhere possible in my trunk and I still had constant rattling. Really a disappointment when that's the main reason I bought the mat for.

Good stuff

This dampener does what it's supposed to do. Didn't get to use it how I wanted to, but that's nobody's fault but mine.

NVX sound dampener

This product is easy to work with. You just need to peel it off and apply. I suggest you use a rubber roller with it.

Excellent

Great stuff. And I mean GREAAT. Gets rid of unwanted flex and looks appealing. Can't beat the price either

bon produit

je ne connaissais pas mais pour le coup,il est formidable mais toujours le problème de facilite d' utilisation.

NVX SDVK4

The material looks and feels like a good quality product. It's heavy and got a thick aluminium backing. Additionally it's easy to work with and forms nicely to the contours of any surface.

I recommend this product.

Quiet Performance

If you are looking to improve the response of your speakers, look no further. This material helps dampen the area in which it is installed. I placed this material in the doors of my truck which improved the sound quality in the vehicle. I would never install any speakers without this material. Install, you'll be glad you did!

Great Stuff!!

I bought a small amount of this stuff wondering how well it would work to just eliminate the rattle in my trunk lid. I drive an E30 so the trunk lid is really light and rattled a lot.

Once this stuff was on, about 90% of the rattle was gone and this was just enough to put on the underside of my trunk lid. My bass inside the cabin also seems to sound a lot more clearer too. This won me over for sure.

Can't go wrong with some NVX!

I installed it with a small floor seam roller I picked up at Sherwin Williams and a hair dryer to heat up the material a little bit to make it more malleable to fit the curves of the bracing. Super easy to install. Took me all of maybe half an hour. Just make sure to clean off your surface before installing.

NVX SDVK4

Good product at half the price of other brands.Will be ordering more.

Great Sound

I would recomend this set, they sound crystal clear and worth every penny...

Good Speakers

I would recommend this set, they sound crystal clear and worth every penny. I have used them before and they sound great in both vehicles.

2004-2007 sequoia JBL replacement

Replaced the rear door speakers in my 2005 Sequoia. Wow EXCELLENT. WORTH the trouble. Too small for the front door IF you have JBL 10 speaker system. An 8" woofer works it already has a mid and tweeter in the front. (FACTORY AMP)

Great quality for Infinity Kappa

This is a great company!!! Service was fast and the price was very good for the quality!! I do recommend

Great speakers

These sound amazing when you give them more power with an Amp, they sound great without being amped, but really bring the music to life with more power! Get these speakers and you won't be dissappointed!!!

Infinity Kappa 62.9I

Its fine

Great sound

Great value for all the accessories that came in package

Some of The Best Speakers You Could Get

I just bought these speakers about a month ago, I got em to replace my old Kenwoods that just didnt give me the quality I wanted and from the first moment that I turned on my radio I noticed a huge improvement every note is clear and crisp and they get pretty loud. Im planning to amp em up soon with a MTX Thunder Elite amp cant wait to hear em then.

Infiniti kappa 62.9i

I bought these speakers 6 months ago. Great speakers at a great price.fast shipping. Would definitely recommend!

What is This Stuff?

When I ordered this stuff I really did not know what it was or how to use it but it became very apparent. I cut this sheet larger than the hole for the speakers and pulled the adhesive off and stuck it over the hole then cut slices from the middle of the hole and folded it under so all edges were smooth. Installed speakers on top of this and there you have an airtight cushion that the speaker sets on top.

Better then dynamat

This product work better then dynamat and its way cheaper! I would reccomend this to everyone I used it in my door panels and there is no rattle what so ever!!! Thanks sonic!!!

good speaker

That was a good buy and sound good and like design and i will buy more

Good value, thick material

Much better than some alternatives I've used on Ebay. Thick material dampens vibration and road noise quite well.

By andrew on July 13, 2015 Verified purchase

infinity Kappa 62.9I

I have had alot of speakers and i think i like these the most there not as sharp as my old memphis but they are sharp and verry loud and if you put them on an amp they will blow you away and can keep up with a audioque HDC3 18" sub ...I am going to put them in my other cars...build quality is better then you think your going to pull them out of the box and say wow!!..

Quality product

Easy to install,works great for the purpose. May want to buy larger amount of product if doing more than 2 doors!

great speaker and great seller

Speaker is great with good sound and solidly built. this is my second pair cause the first were defective, but let me mention that sonicelectronix is a great seller to deal with. they worked with me despite of my return being damaged during shipment. they still sent me a replacement with no problem.

Amazing High and Mids

I have two sets of these speakers and i love them. I have them running at 100 watts RMS off of a 4 channel amp with a Kenwood head unit. I haven't been able to get the bass I am looking for out of them but running them with a sub woofer is an all around amazing system. If you want a reasonably priced speaker with amazing highs and mids then these are your speaker.

Clear Great Sound !

High quality sound, easy to install, fair price, I would recommend them.

Sounds Amazing

Really happy with the speakers I bought! Really loud, clear and plently of bass if needed! Owned it for 6 months still blasts strong. Broke my other kind due to off-roading but that's my fault! Lol
Just buy them and you'll be happy!

Easy installation

Was buying home depot junk than got a roll of NVX. Lays down great and stays in place! Made a world of difference in my 500 hp trans am with exhaust you can hear a mile away. Could actually talk inside the car after laying it down on the rear of the floor and hatch area. Have bought more since and will continue to!

By Richard on March 24, 2017 Verified purchase

Works very well.

This is the first time using sound deadening material. But i can tell you this is worth it.
Makes a plastic factory sub box more solid.
Great product.

Good buy

The infinity kappa 62.9I are good speakers for the money they have rich sound and ample bass from a 6 1/2 inch speaker. I would recommend them.

great sound

I currently have this set connected to my head unit and with bass and volume all the way up doesn't push them to the max they need a separate amp relly good value for the price ima order another set

Sounds great

I actually put these in my boat. They are sounding great. I replaced the stock Fosgate speakers with these infinity and you can tell the difference in sound quality. Deeper, more rich, warm sound. Great price too!

Best speakers I've ever installed

Paired with a 75 watt X4 amp, simply amazing the power and clarity I'm getting. Didn't even need to install the subwoofer...you can barely hear/feel it. If you want a sub to keep up, make sure you get a 10" or 12". (A single 8 is what I'm using)

Better than I Expected

These are very clear and bright-sounding speakers. I did not think the bass would be all that adequate, but it is definitely adequate for classic rock. Probably not for rap, though.

Great sound at a great price

Bought for a 1997 Cherokee. Fit in with a few simple modifications. They are a little too deep for the doors but no cutting was required. Sound great and will be buying a second pair for the back. Would recommended to anyone looking for great mid low and highs all around. Sound fine just off the head unit as well

great clarity

Running these off a kicker DX 4004 amp. Very impressive for a non-component 6.5

Great Value

I put two sets of these speakers along with a JVC KW-XR810 stereo in my son's '03 Celica GTS. We were on a budget so we did not go with component speakers. I was amazed at how much better this system sounds than the factory stereo with the JBL speakers. The bass that comes from these 6 1/2" speakers is unbelievable. I was leaning towards staying with a JBL speaker but after I did my research and compared the performance specifications these Infinity Kappas were clearly the best bang for the buck.

Personal Opinion

I was trying 62.9l The Infinity Kappa rear door of a Peugeot 307. The doors were soundproof, but ue into the car door is ue boring, because they originally come factory coaxial cable bolted to the panel, so we had to supplement a wooden ring to fit.
Went with a Kenwood stereo and X994 volume of 24 sound great and have very good shot, a sound very linear, more than 26 distorted, but is normal in non-amplified speakers.

Infinity Kappa 92.9I

Since I have installed these speakers in my jeep's sound bar, the clarity has been amazing. They totally blew the factory sound out of the water. They would probably sound better if I were pushing them with an amp, but even without one they still rock.

worked perfect

very easy to use. careful tho. only 4 sq ft not the 4 cu ft i thought. misread and assumed. my mistake. covered trunklid and works like a charm

NVX SDVK4 - 90mil 2.3mm THICK

Works great. It’s perfect for every application and completely eliminated the annoying rattle from the trunk.

Awesome stuff

Previously bought the NVX door kit and was highly impressed, its just as good as all the name brands . Purchased this to finish my build ..even have NVX amp and speaker wire kit , NVX hands down is the real deal .

By Chris on September 28, 2017 Verified purchase

Works Great!!

This is the 2nd time ive used NVX dynamat for my vehicle and it makes a difference everytime. Ive acually used on the exterior of my vehicle under the body panels of my cadillac fleetwood which has a bunch of chrome panels and it does the job! Would definitely recommend to stop rattling on your vehicle!

Looks good

Didn't get a chance to use it yet but seems pretty good

Great product

Great product at an outstanding price. Easy to install and definitely helps with the sound.

Great Speakers

I used these to replace front door speakers in a Saab 9-5. They looked excellent, had no issues with the install and they sound wonderful. \\they went in a very good HK factory system. A big improvement but are of the quality that with upgraded amps they would really shine. A great deal at this price point as well

infinity 62.9i car speakers

I did the self install on these speakers. The job was not difficult. You just have to take your time, no one is going to do a better job then you.!! The TWO most important thins you must watch out for on the install: The depth of the speakers with your glass windows and the wire dongle from the speaker. Not a BIG Problem.!! I just drilled two holes on the side. Slid a plastic Cable Tie in one hole around the dongle into the other hole, then tie off.!! Held secured, no rattle.!!! These Speakers are Wonderful, it is worth the investment of your time.

Crazy loud speakers

Loud speakers with great bass. Clear and crisp good price for the quality

Very clear sound....

Hi, i bought two pairs about six months ago and I'm very satisfied, they are connected to a Phoenix gold 4 channels and let me tell you that they can take A LOT of power....the limit is my ears....:)

Easy and effective

Easy install for the trunk, Would need more for doors in the future

A nice solid piece of sound dampening. Works as needed and isn't hard to install even without the right tools.

Better than the others

Stuff is as thick if not more than a lot of other more expensive brands.. I have never heard of nvx but with this type of quality I kinda want to try their subs out now..

By Kelvin on March 13, 2016 Verified purchase

Good speakers and value.

I have installed these is both of my teenage kids cars and they have held up very well. Good sound and very durable.

amazing durability and sound quality

5 out of 5 all the way. Crystal clear highs and great lows for the price. Definitely my kind of speaker because they are extremely durable as well.

Great Sound Dampening Material

I used this to line the front doors of my car. It is very easy to cut with a utility knife and the adhesive is very tacky. I applied with the handle of a screwdriver which worked great. Applied around the speaker mount and inside of the door panel. Door skin is now very solid sounding and midbass also has a more solid sound. I will be purchasing a bulk pack in the future to apply to my entire vehicle.

Take note that there are other things that rattle than the metal before stating this product does not fix rattles. One, it could be that you did not apply to the area that is actually rattling. Second, be sure to wrap all wire, cables, and some mounting clips with fleece TESA tape, which is sold on this site.

Great Speakers

These speakers are amazing for the price. I've had them for a year in a Toyota Celica with two Memphis 15's and I've only blown one speaker so far. They are extremly loud and fairly cheap, they are definatly worth the money

Great product for the price

I bought four of these speakers about a year ago for my tacoma and noticed a great improvement over stock speakers. Installation was fairly easy. Adjustable tweeters are a plus on these speakers and produce great highs as well as bumbling lows. for 6.5" speakers these are a great value.

Amazing

I am not sure if its just because I have been listening to the stock speakers for so long but these speakers pump hard. I have my amp tuned to only play the high pass through these speakers and they still hit pretty hard with a decent amount of bass. I would definitely recommend these speakers to anyone.

Exceptional Speakers - Exceeded My Expectations

Every pair of 6 1/2 speakers that I have purchased throughout the years has been a disappointment, mainly due to the weak bass and poor imaging. These beauties were definitely an exception!!! Installed in an 07 Accord Sedan, these babies produce resounding highs, balanced mids and SURPRISINGLY low lows. They are a fantastic complement to my 693.9i speakers. And the kicker is that they are only powered by the stock stereo. I'm satisfied as-is and can't wait to see what they sound like with an amplifier. The only down side that I can think of is that the base is lacking at low volumes, but an amp would cure that. If you're installing them in an Accord use the Metra adapter #82-7803 and some self tapping screws and your in business without cutting or fussing. HIGHLY RECOMMENDED.

simply AMAZING!!!!!

ok so i have a 2001 ranger edge that i am installing my stereo system in. first off my stock speakers are 6x8's and i prefer round speakers, so i purchased a 2 sets of scooche speaker 6 1/2 mounting brackets for the 6x8 speaker openings, these infinity kappa's fit perfect. so i wanted to get something that i could afford but still sound AMAZING!! these are by FAR the speakers to get. i bought 2 sets and i dont even have my aftermarket deck and amps in yet and they sound AMAZING!! i am buying a Kenwood eXcelon KDC-X792 deck and then i am buying a decent 4 channel amp to power these. i have an ascendant audio arsenal 15" subwoofer thats going behind the seats so i definitely need a set of speakers that can get loud sound great and be able to overpower that sub if needed. these are them! i love the look of these speakers with the woven fiber cones and the ability to aim the tweeter at the listener really makes a difference. the external crossover is a MUST with any good audio system. i used to have a set of polk audio momo championship speakers i loved them, actually the two are very similar to eachother!!! but they dont make them anymore so, needless to say i have these bad boys. if your looking for a great set of speakers but dont have all that much money, jsut save up an exra bit of money and get these, dont be in a hurry, you'll regret it. i mean these speakers compare to sets for 3 times as much. cant wait till i get the deck and new amps. i'll get back to you when i do!!!!

Super sticky, super sound proofed, super oh ya

The youtube video definitely helped me get the strategy to roll this stuff on correctly. Thank you to Allyn for all the videos. I have now mastered my DIY skills in car audio.

Best

These are really good got these on a tahoe on all four doors and it souds amazing i had kickers and these are way better

Great speakers!

I would recommend these speakers to anyone wanting to upgrade a factory sound system . I installed these in my 2006 GMC with bose system . Definite improvement from factory speakers. Durable and have great sound . Very hard to find 2 OHM speakers but Sonic Electronics had them at a great price. These speakers play crystal clear at full volume.

AMAZING SPEAKERS

I have these speakers in the back with the component infinity 6030cs' in the front and theyre running off of the infinity 475a 4 channel amp. the highs get REALLY loud and the sound is powerful and clean and they compliment my 12 inch l7's nicely!

Great quality

These sound great in my car! The quality of sound that comes though the speaking is top notch.

Superb sound at a fair price!

Ive been using Infinity Kappa series speakers for YEARS in several different cars and trucks. The 62.9i Kappa’s are incredible! I installed 4 of them in my old 2000 Rav4 but have used this same speaker in my Tacoma 4x4 and in the doors of my 2000 Mazda MX5 Miata. I must say that they come alive with a proper amplifier or high quality head unit. Do yourself a favor, set the bass at 0 and begin turning the mid and high end up. ONLY after feeding them some power!! Im feeding my Kappas with about 20 wats RMS all the time, my Bass is set at -1, mid at +4 and high at +5 and it sounds incredible! Im running them in foam baffles with the bottoms cut out too. I only drop the ease of use category because of the factory installed outboard cross over, it makes installing them in certain locations a pain...

great little speakers

Very good sounding speaker that handles a good amount of power. I run 75watts rms to them and they sound good. I recommend using hushmat or dynamat when placing them in the doors of your vehicle. Also get some tie wraps or aka zipties for the little crossover.

The reason you should buy name brand speakers

I have these in my 94 camaro and after owning sony, pioneer, jbl and kenwood I can honestly say these are the best. No other speaker this size gives this much bass for being so small.very loud and clear but to really get the best sound you need to amp them and have a good head unit with a good level of adjustment. They will still sound good just off the head unit but not once you turn the volume to the max. my kenwood plays them good just a few ticks under its max. You can adjust the angle of the tweeter buy only twisting it so DO NOT PULL ON IT TRYING TO MAKE IT PIVOT cause it doesn't. I thought i would adjust the crossover and turn the tweeter down but it gives you perfect detail without hurting your ears. I mostly listen to hip hop which can some times be bass heavy and blow most speakers so the built in crossover is nice

Brilliant!

Easily best bang for you buck. Have these installed in a 2001 civic sedan in the front kicks and back panels. These speakers were a super easy install. Ran them originally off the head unit (Sony CDX-GT930UI) and off the head unit they sounded beautiful. Then amped them off a cheap 4ch amp i had lying around and sounded gorgeous. The bass response off these is amazing for a 6" coax. They were a little bright for my tastes at first but if you hit the tweet button it will throttle it back -3db and it sounds absolutely perfect. Oh yeah and these are much cheaper than a lot of other coaxes ive dealt with in the past but sound just as good if not better than their more expensive counterparts. Worth every penny and versatile for running off head unit or amped. I highly recommend these.

So how do they sound?

What can I say, choosing speakers isn't easy. There is no way to listen to them all before your purchase a pair. You can go to Worst Buy and play around with them but you can't get a good listen in before a store goon comes up to bother you. Honestly, what are you to do? In my car I have an Alpine 9885 head unit, stock speakers, Kappa Perfect Sub hooked to a Kappa One Amplifier. I was between getting these infinity speakers to go along with my infinity Sub or getting Alpine Type-R speakers to go with my head unit. Long story short I bought the Infinities for two reasons; a) Type R speakers were sold out on this site and b) the Infinity's were 2 ohm which is a plus because I am running them off the head unit. So how do they sound? Well, they sound awesome, these things really sing. Running off the head unit they still get plenty of power and get way to loud for me before they distort. The sound is clear and the lows are complemented very well with my sub. I am glad I bought these speakers. I have no idea how the Type r's would have sounded but I don't care because the infinity's are great speakers and I am happy and that's all that matters. Also, if you read this entire review than you are probably an audio freak like me that spends way too much time scrolling the products on Sonic Electronix and I just thought you should be aware of that. Keep your volume up and your windows down, You'll hear me before you see me.

great stuff. I have used stinger before this one as they really are a must have on 85% of the cars out here if you want good sound. I would say its a very fair price as i think there is only 1 other sound damper that is cheaper but it also is .02 mill smaller. so all and all it was a must have as my Infinity Kappa 60.11cs speakers sounded like crap until i put this in and now the are the best sounding speakers i have ever had

I put this on my Tacoma since the box of my speakers were hitting metal, once I installed this nothing but fire from the base then before when it was all metal hitting

good sellers

I recommend Sonic Electronixbecause I like the way ideal with them and they're fast shipping specific and details on their descriptions of the item

Thumping speakers

I put these speakers in my 2003 dodge Dakota with the infinity system because my old speakers were blown due to them being 11 years old and some very heavy bass. I replaced them with the 62.9i's and they are great replacement speakers for a factory system with an amp, wonderful bass and great sharpness. I'm highly satisfied with them, they ROCK!

Infinity Kappa 62.9I

Great speaker, excellant sound, watch mounting depth. Pig tail is awkward when mounting as front speaker.

infinity kappa 62.9i

These speaker rock!! They support surround sound and they sound very clear even at high volume. I recommend them very highly to anyone.

sounds great

For the money these speakers sound great.

Great Sound

These 2 ways have a great sound once amplified, but were lacking without the amp. I would recommend them to anyone planning on amplifying them.

Great buy

For the money you can't go wrong with these speakers exactly what I was looking for , have to replace one more on the dash board & I will go with infinity

Great sounding detailed speaker

Infinity has been my standard for over 15 years now with infinity Kappa's as my go to speaker. These speakers are replacing the former set due to one of the door speakers developing a rattle in the speaker after a few years of daily hard use. This version of the Kappas excels the earlier version that I had installed as far as build quality and slightly better in term of sound quality. I appreciate the built in crossovers and rotating tweeters that other manufacters do not offer. I actually purchased another manufacturers speaker but returned them since they did not match the sound I had grown accustomed too with the Kappas.

Great speakers

These are great speakers everything about them great sound clear and u can't beat the price

awesome speakers for the price

I put this on a 95 honda paired with 2 6.9 in the back and the sound is amazing crisp clear sound.I would definitely recommend this speakers they are solid

LOVE LOVE LOVE my Kappa's!!!

Great sound, full range, and can handle some POWER, so please, GET A AMP!!!!

Awesome sound

These speakers are clear with an awesome sound. They handle a wide range of music. Great value. I would rank the sound quality alongside of speakers priced twice as high.

great value

Great Bike Speakers on 2014HD

Got these to replace the oem speakers in the front fairing on my 2014 street glide. The originals were 2 ohm, so I chose these as a direct replacement. HUGE improvement! much more clarity, punchier bass, crisper highs, and a good bit more volume. I ended up added a Fosgate PBR300x2 amp and the Infinitys really came to life. Bike sounds better than most cars now. Only MINOR complaint is the crossover/connection point hangs off the speaker so you have to add extra steps for mounting it.

Awesome Deal

These are some good speakers! I would recommend them to anybody! The sound is amazing, you want these in your car! Quit stalling and buy them already!

Awesome

GREAT SPEAKER , WORKS BETTER FOR ME ON A AMP BUT GREAT UPGRADE FOR STOCK SPEAKERS.

Pure Sonic Bliss in small ride!

These are installed in a old school Toyota that could only fit 6" speakers in the doors.. powered by a Kenwood Excelon XR-4S. WOW! Nice quality sound that won't break the budget. Get these Kappas .. you will love them. They are crisp, full and dynamic! Nice SQ speakers. Good job Infinity!

FANTASTIC COAXIALS!

Absolutely LOVE these coaxials. These are 2 (ok 2ish) ohm speakers so they get the perfect amount of power from your amplifier or even from your radio's built in amp. The tweeters are not overly metallic and have a pure natural sound. Very reminiscent of the Emit-R tweeters in my home speakers. PLUS they are directional and have the ability to attenuate their output to easily match your stereo and personal preferences. Lots of midbass from the oversized woofer cones and all nice and tidy in a great 6.5/6.75 package. These went right into the rear doors of my Traverse and match the 3.5" kappas that I installed in the 3rd row factory holes. Beautiful speakers, beautiful sound.
