I got the Polk Audio db651 6.5 in speakers. I have a Dodge Dakota Extended Cab and got 2 pairs. I am VERY impressed with the sound clarity and just sheer power of these speakers. Granted it is in a truck cab but these things are extremely loud. They have great clarity at all volume levels and are able to play loud enough to make me yell at my passengers to be heard and they still didn't have any distortion. For $65 a pair they are a steal. I'm only running 22 rms thru my head unit and they can take 60 rms I believe. I highly recommend these speakers to anyone.

Good speakers, great price. A great mid line speaker that really comes alive with clean power. I have db series front and rear in my Toyota 4 runner on a jl 500/5

These sound great as long as you give them the power they need. They wont come alive unless you amp them. Good quality and easy to mount. I'v been running them for a few months now and sound great.

My set up is a simple consisting of a pioneer head unit, jbl gto 1004 amp, and polk momo (mm1240) subwoofer. The excel in both the department i.e. sound quality and sound pressure level.
I was surprise to see that this speaker sounds great without any distortion, secondly the build quality is upto the mark. The sound quality was good not on par with the momo series.
Cons: As compare to the polk momo subwoofer I found that this speaker were not keeping up to my expectation.

I put the Polk Audio DB651 Speakers in to replace some 8 year old speakers. They sit exposed, but under shade on the center console of my boat in the Florida sun. They sounded great day 1 with nice tight bass, clear mid-range, and bright highs. I listen to a wide range of music and I'm pleased with the sound. If you are looking for head banging bass, you'll need to add a subwoofer. For me, they were reasonably priced, durable, and sound great.

Good speakers have had them for over a year now and they still play great, clear sound and they were reviewed on one site as being one of the top notch 6" speakers and they were right.

Speakers sound great.

For whatever reason I did not have any bass with these speakers in the doors of my 2005 Hyundai Elantra. The factory junkers had better bass. However, if you are using a subwoofer they will sound nice.

These speaker rock. I have them on a four channel hifonics amp giving them 110 rms a piece and they are loud and clear. Buy them, you wont be disappointed. Just ordered the db691 to match today and cant wait to see how it all comes together. Got 2 12 inch L7's and a kicker 1000.1 and it sounds like a concert! Thx sonic!

Got these speakers to replace stock Kia speakers. Ended up keeping the stock speakers because these ones have terrible bass output. They were great for full range, almost making music sound 'live' - everything was good but the bass, so they had to go.

I have them in a 08 scion xb and they are great for highs and mids they do great with my pioneer 3200 bt along with a alpine type r 12 I would recommend to any who want better door speaker than factory at low price.

I have never been disappointed with any speakers I've bought from Polk. These 6-3/4" went in the doors of my firebird and fit great. They are powered by 50w pioneer head unit and seem to be getting enough power for my purposes, but more never hurts!

In the hatch I have 2 RF 6x9's in ported boxes and amped 100w to each. This has a good stage for music; clean mids and sharp highs up front from the smaller polks, and more low end presence from the back 6x9s.

These are awesome for the price and they're marine certified so they should hold up fine to being swung around inside the doors, exposed to weather.
Low end Hz are somewhat disappointing, at least in my setup, but match these with subs and it would have awesome range.

Good speakers for the price. Using a Nak amp to power them. Speakers would be good for any normal application.

Now in my car the side door speakers are just mid bass but i went ahead and got coaxial because components wouldn't have fit. Anyways the are loud, decent mid bass, great tweets, cant wait to hook up a amplifier.

WARNING: when i was installing the 3/4 bracket didn't fit, and it was made for my car. i made some adjustments and got the speakers to go in without the bracket but do note it will not fit dodge neon !

Purchased these Polk db651's to replace the stock Clarion speakers on my boat and am very happy with them. They sound good and play very loud. I would definitely recommend them to anyone looking for a budget speaker. I will probably replace with the MM series at the end of the summer, as have added an amp and have Polk MM650UM's in speaker cans. Overall very happy with these speakers and all of my Polk products.

These speakers sound very good. I put them in the doors and they sound great. good balance between bass and treble.

These speakers are crystal clear without sacrificing bass. Replaced stock speakers in our boat and added a 10" sub. This thing rocks on the water.

I have purchased these to upgrade the audio in my 1982 Dodge, and am very pleased with the result. I am driving them directly from the head unit, and also have a pair of Kicker 6x9s that I drive from an amp. The two seem to work together quite well. The Polk has a slightly more refined sound while the Kicker has a little bit of an edge, but together they sound great.

Highly recommended.

Bought these speakers to replace the 4 OEM speakers in my 1999 Toyota Tacoma xtra cab. Fitting in the factory location requires the scoshe adapter plates #SAC-656, and a bit of work, but they will go into place behind the OEM grills. Compared to my OEM speakers, they sound great for a 2 way speaker. Thanks for the excellent customer service SE!!

I am running only 45 x 4 amp, so at lower volume levels there's not much mid and bass. For someone looking to replace stock speakers and keep original headunit, keep this in mind. At higher volumes, they sound great and apparently can handle plenty of power. With my system I can't listen to music loud enough to get them to distort.

I really likes these speakers, I put them in a golf cart, speakers were exposed to the elements and held up fine. Sounded great and looked great!

I payed damn near twice this price, mostly becuase it was near 3 years ago, and from a retail store. but none the less, the speakers perform as though they $150+ speakers, like noted before they only can truly be appreciated with an amp, I have them powered by an eclipse EA4000, 75 watts a speakers rms, EXCEPTIONALLY sharp highs, and i mean SHARP,and not to bright. once they are tuned right, they sound amazing, I have 4 of them, and 2 in the door and 2 on the back behind my seat's that use the trunk as a bass tube to give it a little more thump, with the bass turned up, and the low's turned right, they hit so nice you'd swear their was an 8" sub back their.

These are a nice upgrade from the one-way speakers that were in the sound bar in my '08 Jeep. They fill out the spectrum well and, with a sub-woofer, you get a nice, full range. Excellent bang for your buck. The adapter ring (included) is needed so be prepared for a little drilling.

As all the Polk coaxial's, these have a nice clear sound from the silk dome tweeter and plenty of bass. But putting the amp on them is the only way to fully appreciate their sound.
