Our take on the Polk Audio db651

by Leigh Schoettinger
Polk Audio

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.

Good music becomes great when you hear it through Polk's db Series car speakers. Polk engineers use laser imaging to determine the ideal combination of speaker materials and design to eliminate distortion. The resulting technology produces speakers with smooth frequency response, sharp detail, and the ability to play music at high volumes without strain.

Polk's db651 speakers feature 6-1/2" woofers made from a polymer/mica composite and durable rubber surrounds that won't fall apart under stress from heat, moisture, or time. Liquid-cooled 3/4" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction, enveloping you in bright musical detail. And you can even pivot the tweeters, aiming them at your ears for improved stereo imaging. The built-in two-way crossovers keep the high and low frequencies flowing to the proper drivers for seamless, efficient audio.

These speakers feature stainless steel mounting hardware and muscular ABS grilles that will add a stylish touch to your car's interior.

The supplied adapter rings enable the db651 speakers to fit into both 6-1/2" and 6-3/4" openings, ensuring an easy fit into VWs, Audis, BMWs, and other European imports.

Highlights:

  • 6-1/2" 2-way car speakers (pair)
  • supplied adapter rings allow for fit into 6-3/4" locations
  • Dynamic Balance polymer/mica composite woofer with butyl rubber surround
  • 3/4" pivoting liquid-cooled silk/polymer composite dome tweeter

Features

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Woofer Cones: Each speaker features a Dynamic Balance polymer/mica composite mineral-filled cone. The cones are stiff and lightweight for big sound and low distortion.

Butyl Rubber Surrounds:For a smoother response and improved durability, the woofers use butyl rubber surrounds.

Kapton Voice Coil Former: The low-mass Kapton Voice Coil former is lightweight for high sound output. Kapton's high melting temperature (725°F) ensures high power handling and longer reliability.

Silk/Polymer Composite Tweeters: The 3/4" liquid-cooled, silk/polymer composite tweeters provide clear, detailed highs. The tweeters use neodymium magnets.

Pivoting Tweeter: The tweeter pivots, allowing you to to aim it toward your listening position for better imaging.

2-way Crossover Network: The built-in 2-way crossover network sends the appropriate frequencies to each driver for cleaner sound and better imaging.

Mounting Ring: The supplied mounting ring has mounting holes for both 6-1/2" and 6-3/4" applications, allowing the speaker to fit more vehicles. In most cases, the ring should be used to mount the speaker.

Grilles: Strong ABS plastic grilles are included. These computer optimized grilles are based on exclusive MOMO designs.

Super Loud and Clean

Written By JJones, South Carolina on Monday, March 17, 2014
Crutchfield Customer Review (What's this?)
 
I installed these speakers in the front doors of my 2010 chevy silverado extended cab and they were perfect. They are super loud and very clean and crisp sounding. You can hear clearly from about 10 feet outside of the truck when my stock radio is turned up all the way. They don't have great bass, but it certainly isn't bad.
Pros:
loud, clean
Cons:
distort at high bass

Polk Db651

Written By Engguy, Georgia on Thursday, December 26, 2013
Crutchfield Customer Review (What's this?)
 
2nd time I have bought from Crutchfield. Installed in rear door of 2005 Nissan Frontier. Pretty straight forward, did have to drill out the mounting plate holes as they were way to small to get the speaker screws started straight. Also had to extend the bottom mounting whole a quarter of inch to match factory door mount. Any way speakers sound great! Bass for classic rock hits pretty hard. Powered by a 25watt JVC head unit I bought last year. Was going to get amp and sub next year but might not have too. Can hardly wait to hear speakers once they are broken in, since I have heard they sound better after a several hour breakin.
Pros:
Sound is great for classic rock. Bass was much better them expected when I listened to Boston's More Than A Feeling. Also sounds great when playing the 1812 Overture.
Cons:
Mounting bracket had to be drilled, speed clips provided by Polk had to be removed in order to fit in factory mount.

Factory speaker upgrade

Written By Gary, Los Angeles, CA on Thursday, December 05, 2013
Crutchfield Customer Review (What's this?)
 
My 2011 Silverado 2500HD came with a Bose Audio System. You would think that if Bose was going to put their name on something and maybe introduce someone that has never heard any of their product before, they would want to do a lot better than this. After upgrading the front speakers to the Polks there was definitely an improvement. Brighter and smoother top end and a little less distortion at louder levels. But not a significant change.
Pros:
Better high frequency response than the factory speaker. Less distortion.
Cons:
Not worth the cost and labor. Looks like to get the improvement I expected I'll have to revamp the whole system.

Let the music flow.

Crutchfield Customer Review (What's this?)
 
Both the Polk Audio db651 & db651s sound great with my stock 2006 GMC Sierra Crew Cab truck radio. As expected the radio volume is turned up just a bit as the speakers use more amps. My design criteria was to replace speakers and have a clearer sound. The base is adequate for my ears that are north of age 50. Now I'm back to cleaning & detailing the truck.
Pros:
The speakers preform and sound better than the factory speakers.

Okay

Written By Mike F., Temecula, California on Wednesday, November 06, 2013
Crutchfield Customer Review (What's this?)
 
These sound okay but could be better. Maybe because it's only 6.5"? I got these to replace my 6x9's because the tech guys at Crutchfield told me that aftermarket 6x9's will not fit. I would have to get 6.5" with adapter plate. Well, I tried that and they fit but the sound size is very small compared to my stock 6x9's, so I returned these speakers back to Crutchfield. I did some sizing up and had bought some Polk 6x9 speakers. The tech was right that they didn't fit but, all I needed is an adapter ring for the 6x9. And guess where I found one? I used my stock Toyota 6x9 speakers and removed the cone and installed the new aftermarket 6x9 into the Toyota adapter. WaLa! It fit perfectly! And it sounds great too! I don't know why I haven't seen any tech forums suggesting this. It was so easy! Plus, I didn't need a wiring harness; I just soldered some new speaker wires onto the existing Toyota connector. Can you say plug and play?
Pros:
If you have a Toyota Tacoma you can use an aftermarket 6x9's as long as you reuse the Toyota adapter.
Cons:
Too small of sound!

Great speakers

Written By Matt, Ohio on Saturday, October 19, 2013
Crutchfield Customer Review (What's this?)
 
The db651 is a nice speaker. Very smooth highs with no harshness and ample bass--it really moves some air. Sound MUCH better than VW Jetta MKVI factory speakers. I had the Polk DXi series installed in a different car with a different head unit. They were nice too, but I like the db series better. The DXi series seemed too sharp on the high end. Not the case with these.
Pros:
Smooth highs. You can adjust the tweeter.
Cons:
None with the speakers themselves. If you are installing in a VW Jetta Mk VI, the speakers will be a good 1.5" away from the door panel--Crutchfield doesn't supply a spacer like the factory speakers have, so some of your sound will get lost behind the door panel. Crutchfield has no installation instructions for the Jetta MKVI either. Really? The top selling VW car? Come on, Crutchfield.

On Crutchfield, 2012 Jeep JKU says db651s fits sound bar and 651 does not. This is incorrect. The DB651 does indeed fit, but you have get rid of the stock grill cover and use the polk ones. I did this, and painted it matte black, and it looked stock

Simply Amazing!

Written By Tracy, Twin Cities area, MN on Saturday, September 21, 2013
Crutchfield Customer Review (What's this?)
 
Finished installing these earlier today, and I already love them! They replaced an older set of Polk's that had been driven hard for eight years and finally wore out, (model db650, bought here from Crutchfield back in 2005). These newer db651's are everything I hoped they would be. I have a 12-inch subwoofer, so I was unconcerned from the start about whether these Polks had good bass or not. Using the head unit's high-pass filter, I cut off frequencies below 80Hz to these Polks. Just love the warm tweeters! Marvelous! I absolutely love these Polks! The warmth of the tweeters is the very reason I bought db's a second time.
Pros:
Clear and warm sound quality. Absolutely delightful!
Cons:
Crutchfield's fit guide does not appear to be entirely accurate for my vehicle. I installed these in a 2003 Dodge Dakota club-cab. Fit-guide says these don't fit in the front door location. I think this might be true if attempting to re-use the Dodge factory bracket, which make the speakers protrude out approx. ¾-inch from the door's sheet metal, but it is not necessary to use the Dodge bracket. You can use the included Polk bracket or the Crutchfield supplied Scoche bracket and mount direct

Distinct improvement over stock

Written By Girish V, Hinsdale, IL on Saturday, September 07, 2013
Crutchfield Customer Review (What's this?)
 
I replaced the last two of the rear stock speakers with these and the sound stage definitely sounded so much more improved. Vocal sound really nice and I can hear words I had never heard with the stock. String instruments definitely sound much better. Bass is not the best, but I do not expect much since I need to add a subwoofer for that.
Pros:
Better vocals, string instruments; great price and look very sturdy and well made.
Cons:
Not the best bass,

Crutchfield Customer Review (What's this?)
 
I was a little hesitant on buying these as I figured crutchfield was just trying to sell polk and I was looking at another name brand but went ahead and ordered these. They came several days later and I installed them in my denali which was super easy. The music that came out was nice, crisp and clear so I am happy to have them. I have a factory amp and these speakers come alive. As everyone else has said if you want bass then add subs which I did and the polks complement the entire sound system. If you want great highs mixed with mids then buy these polk speakers you cant go wrong.
Pros:
price, ease of install, and sound quality.
Cons:
none

Excellent Speakers

Crutchfield Customer Review (What's this?)
 
Recently I purchased a 2011 GMC Sierra truck. Unfortunately the stock speakers were so poor all music was muted and muddy. I knew Crutchfield could solve my problem and did so with the Polk db651 pair of 6 1/2 inch speakers that I installed in both doors. Highs are beautiful, mids are clear so the song words can be understood and the bass is nice and tight.
Pros:
Installation instructions and all necessary hardware to install the speakers included. Nothing was left to guess at!
Cons:
Nothing

Outstanding Speakers

Written By Derrick, NJ on Wednesday, June 19, 2013
 
Great sounding speakers for the money! At first i didnt like the amount of bass that they produced and was a little worried about it. Then roughly 1 month later they completely blow me away!! Alot of people seem to not know about a speakers break in time to really shine you need at least 80 to 100 hours of break in time and within that period do not turn them up past 3/4 of the volume if it is connected to a head unit and 1/2 way if connected to an amplifier. Trust me it is well worth the wait!!!!
Pros:
Best 6.5 speakers for the money!!! Deep satisfying bass around 50hz and the mids are clean and highs are on the flat note (unlike infinity) which is the kind of sound i prefer!
Cons:
The fact that we have to break the speakers in!!!

Great speaker and a significant upgrade to the sound. Did not fit the door, or the supplied adaptor kit. I would have had to use the speaker adapter to mount it on the separate adapter kit and that would have had to be modified to fit the car door I wound up modifying the original speaker/mount and attaching the speakers directly to that
Pros:
Great sound. Decent price
Cons:
Did not fit, supplied mount adapters did not fit. Took some energy to adapt original speaker/mount

I installed these in my 2011 Chevy Silverado 2500HD Crew Cab. The speaker adapters and speaker wire harness connectors Crutchfield provides makes the job so incredibly easy! The master instruction guide from Crutchfield is awesome. Took me longer to take the door panels off then it did to install the speakers. The difference between stock speakers and these polks cannot even be compared. So much better! Also, I have a Alpine amp pushing these and they can handle every bit of power you feed them.

One of my factory installed speakers died in my almost 9 year old truck. So I had them all replaced & professionally installed with these speakers. They sound great. I am not an audiophile but they sound 100x better than my original truck factory speakers...They fact that they are paired up with my none factory Sony explod head unit makes a huge difference..

Polk Audio db651

Written By W.L. Buntin, Danville, VA on Thursday, February 07, 2013
Crutchfield Customer Review (What's this?)
 
I recently purchased a 2005 GMC Serria 1500 Crew Cab and the door speakers were shot. I decided to replace them with the Polk Audio db651 speakers and I couldn't be happier with my choice. The installation was fairly easy and the adaptors included made the speaker wire connections a snap. Just be sure to watch the video on YouTube first to make getting the door panels off eaiser. If you're not handy with a drill and figuring out how to adapt the front speakers to fit, you might want to get a friend to help. The speakers sounded a little flat at first but after a few days they sounded great. Good bass, midrange and treble. If the CD player in my stock radio wasn't broken I wouldn't change it. That will be my next project and I'll probably come back to Crutchfield for that.
Pros:
Great sound
Cons:
None so far.

Great Speakers

Written By JohnD, Kansas City, MO on Saturday, September 29, 2012
Crutchfield Customer Review (What's this?)
 
I got these to go with my JVC head unit in my truck and they sound great. I've had a lot of good experience with Polk DB speakers in the past and these were even better than I thought. I was expecting the bass to be non-existent or very weak, but they are very well rounded and actually thump a little depending on the music. (Your results may vary...it may just be my truck door cavity carries the low notes better than other car doors.) Of course the highs and mids are very good, which is pretty much a given for most Polk speakers and why I chose these in the first place. I bought some pioneer 6.5" speakers for half the price of the Polks to put in the rear just for fill and they sound crappy compared with the Polks. If I had to do it again I would probably get another pair of Polks for the rear, but oh well. That's what you get for trying to save money. Overall they are a great sounding co-axial speaker and worth the price. They are probably about as good as it gets for this configuration unless you step up to component speakerI would highly recommend them to anyone looking for a well performing speaker in this price range.
Pros:
Great sound, well rounded, good value for the price
Cons:
Don't like the grille cover design, but I didn't need them as they are behind the factory door panel screens anyway

Excellent Value

Written By Derek, Lehigh Valley, PA on Monday, September 17, 2012
Crutchfield Customer Review (What's this?)
 
This past weekend I replaced all 4 door speakers in our 2013 Kia Sportage with these units, and the improvement was definitely more than I anticipated. My wife is no audiophile, but she immediately noted the brighter and crisper treble, as well as the tighter, deeper, and more accurate bass response. With the 2013 Sportage, you do NOT have to use the "slim" versions of these speakers, and the factory head unit has more than enough power to drive them.
Pros:
Excellent performance for the money
Cons:
None whatsoever

Polk Audio db651

Written By RLH, Omaha, Nebraska on Sunday, September 09, 2012
Crutchfield Customer Review (What's this?)
 
Clear precise sound is my opinion of this product. A driver of this size is not capable of delivering a lot of bass, but neither is any other driver of this size. If you want bass you need to buy an apropriate subwoofer. As to the value, I cite the law of diminishing returns. You would have to spend a lot more for an incremental inrease in quality.
Pros:
Accurate and a good value
Cons:
None at this time.

Improvement over OEM

Crutchfield Customer Review (What's this?)
 
Installed these in a 2008 GMC Sierra. They play louder with less distortion than stock speakers and the musical details are more pronounced. Cleaner sound with tighter bass response. Not more bass than stock but better bass than stock. Overall I'm pleased with the speakers. This was step one. Next will be the head unit and a JL Audio Stealthbox to complete the audio overhaul.
Pros:
Clean, loud with tighter bass
Cons:
None

I placed the speakers in my Harley Davidson motorcycle to replace the stock ones, and what a big difference. I thought I would need an amp but I didn't. The factory speakers were the problem, my radio just had to be unleased.

I replaced my stock speakers in my 2010 GMC Sierra with these POLK's and I am very happy with the purchase. I also bought a pair of the shallow mount for the front. They are exactly what I wanted and I will add a sub later for more bass. I would recommend these to anyone.

Actually was quite impressed...Bought baffles but didnt realize when ordering that they were are marine speaker so didnt use baffles and was glad since we stuck with factory radio they actually sound pretty good and the baffles would have taken from alot of the sound since it was an OEM radio and not much power output but very please with the bass and it still sits on 0 while treble is about 4 and this is was in a 07 New style Silverado and they dropped right into place
Pros:
Sound great even on OEM radio and installed very easy

Polk Audio db651or Polk Audio db651S?

Written By Sasha, Brooklyn, New York on Sunday, March 18, 2012
 
I am going to share my experience with these speakers in my Nissan Versa 2010 SL. Like a many of us I had a question: Polk Audio db651or Polk Audio db651S? Ok I got them one of each pair. After 2 month of use them and switch them from front doors to back doors few times I can tell you that. Polk Audio db651 has a little more BASS but less MIDS and HIS and sounds great. I left them in the rear doors. Polk Audio db651S in the front doors has less BASS but excellent MIDS and excellent HIS. And compare sound to you old factory speakers you will start missing worm BASS you have from cheap paper speakers but now you have good clear sound. I call Crutchfield and after good advice I ordered and install small SUB under my seat Sound OrdnanceT B-8PT. It was my best investment for my car audio. Never wanted SUB in my car before, will never drive my cars without it. Very impressed and very happy. Thank you Crutchfield for recommend me that!

I installed these in my boat.

Written By Bob C., Sag Harbor, NY on Tuesday, March 13, 2012
Crutchfield Customer Review (What's this?)
 
I spoke with a Crutchfield adviser and after I told him axactly what I had for a head unit, he reccomended the Polks. I was looking at marine speakers which were more money. Well I got them and installed them right away. Holy cow!!! The sound was great. I didn't even need an amp. This was last year I installed them on my open boat and they still sound great. I hose them down lightly when I wash the boat and it doesn't seem to bother them. Well, This new season I decided to change the head unit and also add a third set of speakers so I ordered the Polks again. I received them a few days ago and can't wait to install them in the boat. The four sound great with the new head unit so I know that adding two more is only going to make it sound even better. I trust Crutchfield with all of my car and marine audio.
Pros:
Less expensive then marine speakers, Great sound without the need for an amp.
Cons:
I don't have any!

Really happy

Written By anonymous, Columbia, MO on Wednesday, February 08, 2012
 
I am a cheapskate with an Impreza, and I replaced the stock front speakers Polk mm651's and rear with Infinity 6032cf's. I am still using he stock head unit with no aftermarket amp or a sub. The Infinitys were clear in the high end, but had no bass whatsoever. Replaced them with db651's (I've had polks before in home systems and vehicles) and I couldn't be happier. Very full sound, even at the bottom end. I listen to rock (the who, zeppelin, kyuss, local h, blue oyster cult) and these handle that type of music well. If you're into rap, get a sub and the infinitys would be fine. If you're cheap and still wanna rock, these are great
Pros:
good sound through full range
Cons:
not quite the mm651's

Put these in my 2003 Maxima and they sound pretty good. The extra brackets Crutchfield sent me weren't even needed with my Maxima. It took me about an hour to finally figure out I don't need them, but after I realized I could use the ones Polk sent it only took about a 25 minutes per door (wire splicing). Would be nice if they could include a wiring harness that would fit the Nissan's, but it wasn't too big of a deal. Overall pretty happy with the quality of sound and all the stuff Cruthfield sent me. Thanks Keith for the advice! Next step is head unit!
Pros:
Quality of sound.
Cons:
Extra brackets Crutchfield sent weren't needed. Had to splice the wires in order to connect.

Awesome Speakers

Written By David, Camillus NY on Sunday, September 25, 2011
Crutchfield Customer Review (What's this?)
 
These are really sweet speakers. They replaced the stock speakers in my 2003 Maxima. The difference was nothing short of amazing. These speakers sparkle in the high range and have really tight bass. The stereo imaging is killer. They are mounted in the doors on my Maxima and are just awesome in that location.

I had a set of three way Kenwoods in my 1998 Maxima. Those were great speakers, but these Polks are way better.

No problem with the fit except that the holes in the mounting ring need to be enlarged slightly to match up with the factory holes in the doors. This is in the instructions.

I wish that the Crutchfield kit came with a wiring adapter. It takes some time to cut out the factory plug and splice the wires. Make sure that you have some wiring connections or solder if that's your thing.

Polk Speakers

I installed these speakers on my Goldwing 1800 Trike. db501 in the rear are crisp, great clarity, and enormous treble. db651 in the front are not what I had expected. Even with the treble control turned off, they are still extremely tinny. The are unable to handle bass control at any decent level. They distort immediately when any reasonable amount of bass is used. For the price of the db651s, I would expect a better quality speaker.

after installing these in a 2003 four winns, I had pretty low expectations as far as what the stock speakers put out. I finally had a day on the lake and to say I was impressed is an understatement. The speakers added a nice bass punch without thumping like some of the big systems. The speakers installed easily and have delivered everything I had hoped for a marine speaker. I highly recommend for fellow boaters.

Polk DB Series Speakers

Written By VinM, Peoria, AZ on Monday, May 23, 2011
Crutchfield Customer Review (What's this?)
 
Nice quality and performance for the price point. Along with the promotional discount offer for a second set at half price the total price per speaker came out to about 37$ per speaker.

A musical instrument produces a characteristic sound because of the combination of the fundamental and harmonic frequencies. The detail and texture added to the mid and low range after upgrading to Polk DB651 is nothing less than awesome. I can hear every single note as though it were live. My Factory Monsoon sound system always sounded a little "tinny" to me. Now it's richer and the bass kicks every detail.

Speaker sensitivity is a measurement of the amount of sound output derived from a speaker with one watt of power input from an amplifier. The DB651 is very efficient at 92db and will maximize the performance of a stock car radio/amplifier. My Jetta Monsoon has gone from "okay" to driving you out of the car at half volume.

Awesome result for a simple speaker refresh. Crutchfield Rocks!

Great mid-bass and mids, but highs are overwhelming

Written By afish01, Minneapolis on Monday, April 25, 2011
 
I got these for the front doors in my 2002 Civic sedan (yes, they do fit as long as
you get the right adapter ring). I have them hooked up to an Alpine 4-channel
amp, so each speaker gets 50 watts RMS. They can really pump out the mid-
bass and the mid range is very good--vocals sound very clear and clean.
However, I am disappointed with the tweeters, as they are very overpowering,
so much that at normal listening levels they were really hurting my ears. I had to
use my head unit's equalizer to turn down all frequencies above 5KHz by about
3dB. However, after this tweak, the tweeters do sound good and provide
excellent detail to the music. Just be warned that if you do not have a way of
turning down treble frequencies on your source unit, you may find these
speakers way too "bright."

ATTN: JEEP WRANGLER OWNERS

Written By Holtz, Cincinnati, OH on Monday, March 14, 2011
 
After intense browsing for weeks and weeks I decided to go with the polk db651 for a few simple reasons.
1.) Decibel sensitivity is 92dB (no amplifier required)
2.) Marine Certified (extremely important in a Jeep) and...
3.) Price!$! (with FREE installation gear you can't beat the price.)

I read countless reviews and spec sheets and received mixed signals as to whether 6.5" speakers would actually fit into a soundbar w/out cutting or drilling. With the spacer/adapter bracket provided all you have to do is cut a bit of the cloth covering to make room for the adapter ring. Once this is done you can take the bracket and line up the holes on the inside with the holes already drilled into the soundbar that were used to secure the stock 5.25" speakers. Once you have secured the bracket to the soundbar all you have to do is connect the female and males ends from the speaker to the housing in the soundbar then screw the speaker into the bracket and you're finished!

I awarded this speaker with 4 stars for sound quality with an additional star for make, look and features. When compared to the stock speakers the Polk blew them out of the water. I can't speak for all 6.5" speakers but I can say that these trump big names such as MTX, Sony Xplode, Kenwood and Pioneer. Keep in mind that there are indeed speakers that top these Polks any day but not if your spending less than $150 for a pair of mid-range speakers.

Great Speakers...Little disapointed with Crutchfield

Written By TheBigT, Birmingham, AL on Thursday, February 10, 2011
Crutchfield Customer Review (What's this?)
 
I installed these speakers in my 2006 VW Passat with the factory head. They sound great! I have had them installed for about 2 weeks now so I can't give a review on how long they will last.

I don't need a lot of bass and these give me plenty. I am sure when I get around to replacing the factory head (with more power) they will sound even better.

I was a little disappointed with crutchfield's instructions. I would only give them 3.5 out of 5. I have purchased from them in the past and the installation instructions have always been top notch. The instructions got my door panels off but they neglected to include instructions for disconnecting several of the door controller connectors. Also the pictures were not as detailed as in the past.

They told me these speakers would not fit in my rear doors. They fit better in the rear doors than they did in the front doors. The front doors required a bit a custom mounting (which I was aware of). These simply fit right into place in the rear doors. I'm glad I took the gamble.

This is my second pair in a 2001 Chevy Silverado Extended Cab 4 door. They say that
you have to purchase the short db651S for the front, do not believe it. The db651 fit
perfectly. They are incredible! I absolutely love Polk's sound as well. Had the front
rocking with the factory head unit for a couple of years. I recently just bought a second
pair for the rear. The rear doors call for 4x6, plate, or 4" with adapter. It was SO easy to
cut a small amout of 18ga. steel from the top and bottom of the hole (these require a 5"
hole, the rest is overlap), drilled my own holes and used steel threading screws AND
the little nut clips. They sound INCREDIBLE! My truck blows me away now! I also added
the Kenwood KDC-HD545U! Also HIGHLY recommend. Plenty of crystal clear MOSFET
power to pump all 4 and blow you away! I probably won't even add a subwoofer under
the rear seat now. No need to. They push rock, metal, ska, techno, everything I can throw
at them from my iPhone, iPod, thumb drive, CD, or the built in HD tuner. Get these bad
boys!

Wow! I bought these to replace my stock speakers in my 2009 Chevy Silverado 2500HD

speakers without changing the stereo. I got what I was looking for. I have not used Polk
speakers before but they sound great without adding any other equipment. I also bought
the matching Polk 4x6 for behind the seat and now the truck sounds great. Installation
was really easy and only took about 30 minutes with the included install items and

Crutchfield Customer Review (What's this?)
 
First, appreciated that the second pair was half price. The instructions that were sent
for son's 2003 Toyota Matrix were very helpful. The wire harnesses that also were sent
made it much easier. Had to improvise on a couple of minor things but not really an
issue. Took some time on the first speaker but after that the whole process went pretty
fast. As for the speakers, they were a huge improvement over the factory speakers.
They sound much better with great clarity and depth. I read some reviews about bass
not being that great but in my son's car its more than enough. We really see no reason
to have an amplifier for these as the Kenwood stereo unit my son got seems to do the
job just fine. He's very happy with these Polks!

Polk Audio db 651

Written By AJ, South Plainfield NJ on Monday, January 17, 2011
Crutchfield Customer Review (What's this?)
 
I purchased the Polk Audio for my rear parcel tray of my vw sedan to supplement the
other great Polk Audio ccmponent speakers I purhased for my wagon from Chrutchfield
about 3 years ago.. Because the wagon had limited space for speakers with out
modification and the sedan can accommodate a bigger speaker these speakers added
a tremendous amount of depth to an already quality sound.

My experiences with Crutchfield has always been good because the representatives are
knowlegdeable and 90 percent of the purchases are shipped free and arrive with in a
day or two.

Crisp sound, Nice look

Written By Marek, minnesota on Saturday, November 27, 2010
 
Bought a set of db651's and hooked them up to rockford punch 400.4 amp. These
speakers deliver clear sound even at max levels. The grill gives these speakers
a nice look, which I think is why people always comment on them when they get in
my car. The db651's are a good addition to my sound system, delivering loud,
crystal clear highs and mids that blow my mind every time and keep the smile on
my face.

I love these speakers.

The first time I heard these speakers years ago I was impressed. Today, I still buy these
same ones and they really sound good. I have Polk Audio DB series speakers in all of my
cars. The clarity, the lows and highs just sound so good and clear. I have not considered
any other I highly recommend these speakers you will be happy.

2000 Jeep Cherokee

Written By Mike, Massachusetts on Thursday, November 04, 2010
 
I bought these speakers for my Jeep. Perfect fit for my car. Didn't even have to re-drill mounting holes! I am very pleased with the sound quality. For everyone who says they don't have good bass, DON"T LISTEN, they are comparing the speakers to Subs and of course they don't have as deep lows. Comparing to other speakers they have great bass. I have them hooked up to my factory receiver, so they are very limited. I bet they would sound amazing with a amp but thats just too much money and work.

polk db651

Crutchfield Customer Review (What's this?)
 
I bought these per the recommendation of the Crutchfield salesman. They had a real low
bass frequency spec and they really do put out the bass. I replaced all four factory drivers
in a 2000 Volkswagen Passat (w/ monsoon), leaving the factory tweeters in tact. They are
a great replacement speaker that sound much better than factory. Installation took some
cutting of the metal speaker openings in order for the spring clip to fit. The plastic
mounting ring that comes with the kit for this car doesn't work that well. I hope nothing
loosens up and starts to rattle. The Polk adaptor ring saved the day. Lastly, I am very
disappointed with the size of the speaker itself. The actual speaker is closer to 5 1/4" than
6.5"...but the sound is very good and still worth it.

Got Speakers? Get Some!

Written By Robert, Estes Park CO on Sunday, October 10, 2010
Crutchfield Customer Review (What's this?)
 
Installed two pair in my 2005 Prius wow what a difference! They get better with use, a little break in period helps one appreciate the full sound that these rascals will produce. These db651's have exceptional depth for such a small speaker offering great clarity and have a smooth not brittle high end. This is sound you can live with for a long time. Installation was moderately easy once I figured out to mount the Polk speakers on top of the existing factory speaker. I just cut out the factory woofer cone, clipped the voice coil wires and the six plastic speaker supports and pulled out the speaker. The Polks then fit perfectly on top of the existing speaker frame. Wiring was a breeze with the Toyota wiring harness. The Crutchfield advisor guide does not recommend this speaker for my model car. It should start as I am truly pleased with my new addition and you will be too!

The speakers sound nice but does not have great bass. The midrange is awesome but the tweets are semi ok. They do have great clarity for the voices in songs.

Polk Audio db651

Written By Jeff, Riverside CA on Thursday, September 16, 2010
 
I upgraded the head unit in my wife's 2002 Sienna minivan so she could use her ipod
and let the kids watch dvds. I decided to upgrade the speakers at the same time. I
chose the db651 speakers for the rear and the db6501 for the front. Although Crutchfield
had noted these speakers as not fitting, I took a chance and purchased them anyway.
Install was a breeze. No need for the adapter bracket. The holes were off just by a tiny bit
from the oem. Lots of room on top and below the speaker. The sound is crisp and
clean. I can here so much more detail in my music. Although the sound is good from the
head unit at 14 watts RMS, Be sure to amp these to make them really come alive. I
added Pioneer's 50 watt RMS amp and the traformation is fantastic. The bass is fine
without a sub in my opinion.

Did a lot of research to find something that fits in my son's Chevy Colorado front doors and could handle his type of music. Read about these speakers...went to a local store to hear them...and we decided to order from Crutchfield. Very surprised how clear they sound and also surprised about the bass they put out; which seems to be a challenge for most speakers these days. I should also add that the free instructions wiring harnesses made installation much easier. We used the Dynamat speaker kit and I would suggest spending the extra money to add this to your installation project.

Added Amp Update

Written By richp5, Anaheim Hills on Wednesday, June 16, 2010
 
After a couple of years of use I added a JBL MA6004 Marine Amp (60 w x 4) to the JBL MR17 receiver and what a difference. Chose this amp as it matched the receiver and it was the 60 w rating of the speakers. Volume is the same now at setting 9 as it was at 30 with no distortion and better bass. Very pleased and would highly recommend adding an amp. Running them in a boat BTW. Upgraded rating to a five based on the improved sound with the amp. Seems durable as I've had them for two years in the elements and pounding of a boat.

Good sound, little bass, keeping them anyway.

Written By Riley, Phoenix, AZ on Tuesday, May 25, 2010
Crutchfield Customer Review (What's this?)
 
I bought these speakers for my Toyota Solara convertible which had the factory stereo with the JBLs. The front doors have JBL 6.75"speakers and a 1" tweeters, and the rear side panels have a JBL 3.5" speaker (midrange). I planned on replacing them all with these Polk db651 speakers. After taking out the little rear speakers and installing the Polks, I thought there was a huge improvement over the 3.5" speakers, but there was not much bass even when turning up the bass and volume. The front JBL speakers had an incredible amount of bass when compared to the Polks. Since the JBLs are only 6.75", which are not much bigger than the Polks, there must be some reason why the Polks don't produce much bass. I thought it was because the actual cone size of the Polks is closer to 5" from edge to edge. I decided not to replace the front JBLs but to leave them in since they sounded so much better bass-wise than the Polks. The Polks do have a better midrange than the JBLs, and do seem to need more power to get them to produce the same level of sound than the front JBLs.

They don't produce much bass at all, and not because of the Solara body enclosure It is probably because of the polymer/mylar type material that does not resonate bass frequencies as good as paper does. JBL uses paper. I have some old JBL L36s and they have 10" paper cone woofers and they sound incredible! In the case of speakers and paper vs. plastic, paper wins!
