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 Was this review helpful?

The site said that they would only fit up front. I took a chance and got the shallows for the back doors and was also able to get the adapters and wire kits. Sound is an upgrade.

Written By Rich, USA on Monday, March 11, 2013 Crutchfield Customer Review (What's this?) 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. Pros: Great sound.

They are very loud and crisp. Was this review helpful? Yes | No 5 out of 5 Good Speakers at a decent price Written By Ed, Boston, MA on Monday, February 18, 2013 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.. Pros: Great sound. Cons: Too hard to install them yourself Was this review helpful?

Pros: great sounding speaker. if you can follow instructions and have basic tools its easy. Cons: rear speaker bracket did'nt work with these speakers, mounting holes exceeded the diameter of the bracket. Was this review helpful? Yes | No 5 out of 5 Polk Audio db651 Written By W.L. Buntin, Danville, VA on Thursday, February 07, 2013 Installed in a 2005 GMC Sierra 1500 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. Was this review helpful? Yes | No 4 out of 5 Awesome Speaker Written By RonF, Lake Charles, LA on Thursday, January 31, 2013 Installed in a 2007 GMC Sierra Crutchfield Customer Review (What's this?) For the money, the speakers sound so much better than originals! Crutchfield Team made this installation as simple as it can get! Very happy with the advice received on the whole audio setup! Pros: Clean sound, all connections worked as advertised Cons: Directions supplied were mostly helpful except the disconnecting of the door release cable bracket and electronic connectors for door locks and windows.

Pros: The Best Cons: NONE Was this review helpful? Yes | No 5 out of 5 Great Speakers Written By JohnD, Kansas City, MO on Saturday, September 29, 2012 Installed in a 2005 Chevrolet Silverado 2500/3500 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 Was this review helpful? Yes | No 5 out of 5 Excellent Value Written By Derek, Lehigh Valley, PA on Monday, September 17, 2012 Installed in a 2012 KIA Sportage 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 2 out of 2 people found this helpful Was this review helpful? Yes | No 5 out of 5 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. Was this review helpful? Yes | No 4 out of 5 Improvement over OEM Written By JayK, Fort Wayne, IN on Wednesday, June 20, 2012 Installed in a 2008 GMC Sierra 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 1 out of 1 people found this helpful Was this review helpful?

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.

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 Was this review helpful? Yes | No
5 out of 5 Big Improvement Written By Paul, New Jersey on Saturday, May 25, 2013 Installed in a 2011 Volkswagen Jetta Crutchfield Customer Review (What's this?)

Pros: Reasonable Price Excellent Sound Cons: No real issues Was this review helpful? Yes | No

4 out of 5 like em Written By Abe, Texas on Monday, March 18, 2013 Installed in a 2011 Toyota Tundra Crutchfield Customer Review (What's this?) I got these along with the shallows. The site said that they would only fit up front. I took a chance and got the shallows for the back doors and was also able to get the adapters and wire kits. Sound is an upgrade. If u want bass get sub to go along. Not bad set of speakers though. Pros: Clear sound Cons: Not much bass Was this review helpful? Yes | No

5 out of 5 Fantastic!! Written By Rich, USA on Monday, March 11, 2013 Crutchfield Customer Review (What's this?) 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. Pros: Great sound. Great quality Great Mid range Cons: Wish had a bit more low end Was this review helpful? Yes | No

4 out of 5 Polk Audio db651 Written By Anonymous, Baton rouge, LA on Monday, February 25, 2013 Crutchfield Customer Review (What's this?) Great. Even marine grade. they have built in tweeters so if you looking for bass this isn't them. If you want to upgrade to a nice stereo these are great mids and high speakers. They are very loud and crisp. Was this review helpful? Yes | No
5 out of 5 Good Speakers at a decent price Written By Ed, Boston, MA on Monday, February 18, 2013 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.. Pros: Great sound. Cons: Too hard to install them yourself Was this review helpful? Yes | No
5 out of 5 Polk Audio db651 Written By legin, Hilo,HI on Friday, February 15, 2013 Installed in a 2013 KIA Soul Crutchfield Customer Review (What's this?) bought these polks to replace the factory speakers in my new kia soul. the difference is night and day, the polks handle everything the factory stereo can dish out. they sound great, good bass response clean highs, nice speakers. Pros: great sounding speaker. if you can follow instructions and have basic tools its easy. Cons: rear speaker bracket did'nt work with these speakers, mounting holes exceeded the diameter of the bracket. Was this review helpful? Yes | No
5 out of 5 Polk Audio db651 Written By W.L. Buntin, Danville, VA on Thursday, February 07, 2013 Installed in a 2005 GMC Sierra 1500 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. Was this review helpful? Yes | No
4 out of 5 Awesome Speaker Written By RonF, Lake Charles, LA on Thursday, January 31, 2013 Installed in a 2007 GMC Sierra Crutchfield Customer Review (What's this?) For the money, the speakers sound so much better than originals! Crutchfield Team made this installation as simple as it can get! Very happy with the advice received on the whole audio setup! Pros: Clean sound, all connections worked as advertised Cons: Directions supplied were mostly helpful except the disconnecting of the door release cable bracket and electronic connectors for door locks and windows.

5 out of 5 Great Speakers Written By JohnD, Kansas City, MO on Saturday, September 29, 2012 Installed in a 2005 Chevrolet Silverado 2500/3500 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 Was this review helpful? Yes | No
5 out of 5 Excellent Value Written By Derek, Lehigh Valley, PA on Monday, September 17, 2012 Installed in a 2012 KIA Sportage 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 2 out of 2 people found this helpful Was this review helpful? Yes | No
5 out of 5 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.

4 out of 5 Improvement over OEM Written By JayK, Fort Wayne, IN on Wednesday, June 20, 2012 Installed in a 2008 GMC Sierra 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 1 out of 1 people found this helpful Was this review helpful? Yes | No
5 out of 5 harley davidson ultra classic Written By Chuck, Fort Washington on Monday, June 18, 2012 Crutchfield Customer Review (What's this?) 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.
