This is the first set of component speakers I have ever purchased, and I must say, the sound quality from these Polk component speakers is absolutely incredible. The Polk 6.5 component speakers replaced a set of aftermarket 6.5 coaxial speakers, and the Polk speakers are just so much better sounding. The power handling is pretty impressive, and I have yet to be able to make these speakers distort. The bass response is just so much better than you get with coaxial speakers. I know they are a little pricey, but I have found the sound quality to make them well worth the extra money. I would buy these again in a heartbeat if I had room for them...

Put these in a friends car and the first day they dont sound very good. No speaker does right out of the box. They take a little breaking in. The next day BOOM! The car is shaking! Especially paired with some sound dampening material these speakers along with the db651 coaxial is just amazing! Really rich highs and very surprising that with just a head unit giving out 52 wats per channel and with no amp the amount of bass is crazy! HIGHLY RECOMMENDED!

Awesome speakers, but they need to be amped! Head unit power will not be enough to show what these speakers can really do. In fact, it will make you not like them at all! Amp them and you'll love em! I installed them in my F150. Needed adapter plates and with a little dremmel work, they ended up fitting fine. I ended up installing the crossovers inside the panel under the window switches which worked out great. Polk is very good quality for the price. Just don't forget to feed these speakers power or you will not like!

I purchased these a week ago, and put them in my car yesterday. I ran the factory amp to both, the 6 1/2"s and the tweeters, not even using the crossover assembly. There is a lot of high frequency and mids now with these speakers. I had to turn down the treble and mid range on my radio to half way. WOW! As far as the sound, they blow my stock Clarion speakers out of the water. Yes, I'll stick with Polk Audio. :D

I bought these speakers for a 2003 Avalanche.
I replaced the factory with these using a decent 4 ch. kennwood amp. I mounted the tweeters flush with the supplied housings. When I was done I was a little disappointed with the sound. When I raised the volume I got distortion. I was sure I just needed more power. The kennwood was probably putting out about 100watts per ch. (it was given to me & wasn't in great condition)
The peak on the 6501's is 300 so I swapped the amp with a pioneer 760 watt 2 ch. I left the gain all the way down and tried it. The sound was incredibly loud! No distortion and I couldn't stand being in the truck with the volume all the way up! I wanted to close my eyes and cover my ears. I read someone's review saying they can't handle power. It's a lie! They can handle it! If you want the most bang for your buck a head unit by its self won't do it. My stereo does 80 x 4 and didn't do the speakers half the justice they deserve.
Keep in mind the location of your tweeters makes a difference. Drill your holes big enough so they are free enough to swivel. If you have to fight them in your holes too small.

I bought these speakers and installed them in an 03 avalanche.
I spent all night installing them with a decent 4 ch. kenwood amp pushing them. When I finished they sounded decent but I still heard distortion when I raised the volume to max. The next day I pulled the kenwood and put a pioneer 700 watt 2 ch. amp on them. I kranked the volume all the way up and the sound was incredible. No more distortion and and it is so loud now I want to close my eyes when I turn it all the way up. I won't be turning the volume more than 2/3 of the way up anymore unless I just want to show someone what they can do!

I had the Polk's installed in a 2001 Cadillac DeVille. The front door has the 61/2, but the rear doors will only fit the 51/4. Once I installed the 500watt 4ch amp to them and now they sound AMAZING. Thanks Sonic.

These are the most "natural" sounding speakers I've ever owned. The install in my 96 OBW was super easy and all required hardware was included. I left the crossovers in the small door "pockets" up front so I could adjust the treble +3/nom/-3db, but I found that the nominal setting was fine where it was. I am feeding them 75watts RMS @ 4 ohms via a 4 channel Alpine Amplifier. They are very clear, and very accurate. If you want these speakers to sing, use an outside amplifier as IMO the head unit amp just doesn't have the wattage that these speakers desire. They crank. Totally satisfied with my purchase.

I truly enjoy these speakers. Even without an additional amp they sound great. I also enjoy the fact that they are water resistant, as this should help them last longer and maintain the great sound they produce.

i have had these for about a year and they worked great. they sound good but require an amp. they worked great until one of the tinsel leads broke. the tinsel leads go through the spider so not easy to repair. just replaced them with some cheap autotek atx6.5cx that sound just as good but need less power and cost less.

This set of speakers rocks! They sound really good. They cover the highs and the mids great. Sounds like I have a really expensive set of speakers in my Yucon.

Great product. Great Price. Even with the shipping, duties and taxes it was way cheaper than buying it in Canada. Arrived exactly when they said it would. For sure will be ordering from Sonic again.

These speakers pack a punch and don't give up. They handle high amplified volume with ease. I purchased 4 2 front and 2 rear, I've had them for 4 months now and sound better than when I first installed them. Great adjustable highs and the woofers pack a punch. I have already recommended to friends, and they purchased them also and love them. Also Sonic Electronics has a friendly and knowledgeable people that will help you with your needs.

Great buy for the money. I installed the Polk speakers in my 2001 cadillac DeVille,the 61/2 will fit in the front door but not the rear, had to go with 51/4 and they sound amazing when hook up a 500watt 4ch amp.

Bought the pair after comparing several other brands like kicker, infinity, alpine and other well known brands. Well this speaker set has smooth highs, not harsh like other ones. The speaker looks well built and comes with alot of extras for mounting the tweeters. The mid bass is not as strong , but thats why you get good 6x9s in the back. I have 90 watts RMS running on each speaker. YOU REALLY NEED AN AMP to run these to there full potential. If not they just sound like any other speaker set. Polk Audio has been doing home and car audio for a LONG TIME. So don't hesitate and buy these speakers.

I purchased these to replace my factory ones and let me tell you the price is right and and they sound awesome!

These were the first real set of component speakers i have ever owned. They are good overall speakers for a normal cheap upgrade and please run them off an amp. Any amp would do. So if you are on a budget or just looking for a cheap upgrade over stock i would say get these speakers. If you can spend a bit more look at their MM line they sound pretty good.

Installed these in the rear doors of my 2011 Maxima together with 3 way matching units in the front (db651). Very dramatic improvement in both bass and high frequencies and the overall "open" and clear sound typical of Polk speakers. Very pleased with the improvement for the relatively low cost. Installation took me a morning due to havng to drill the door panel with a holes saw for the tweeters and needing to install the crossover. There are no harness plugs for this vehicel.

Great sound quality good price and accompany my subs very nicely.

Pros: Sounds and looks great! The accessories are great and very strong

Cons: 1. One speaker's surround is messed up... It looks like the seal on the frame didn't completely seal. So the surround was dented a little. It still works, but I'll be keeping everything in case it rips or something. I don't know who to blame for that, but since shipping took way too long I'm not going to return it til it breaks.
2. OEM install of the tweeter is impossible in a Scion xA... but what can ya do?

Other: If you get a perfect pair of these, you can't go wrong. They are great for the price. I have them on 45RMS each and they get loud and have great bass! Definitely would recommend them.

I'm not an audiophile but this system was a lot better than the stock system that came with the car. Many people recommended these speakers for use with Honda CRV's (which I have), had no drama with the install and cannot fault it.

Good for those wanting a bit of bass without requiring a subwoofer. I can't remember what I paid, but I'm usually on the lookout for a bargain, or at least top value.

I currently own both the DB6501 and MM6501. I had the DB first set up in the front of my '07 Pathfinder, then I ordered the MM's and replaced the DB's (the MM's went in the front and the DB's were moved to the rear). All I can say is that the difference was night and day. I was very happy with the DB's so if you are on a limited budget then don't shy away from them, but I will wholeheartedly say that if you are on the fence between the two series that you should definately spring for the MM's. The difference from DB to MM is 'almost' as big as going from factory to the DB's! In the end, VERY happy with my 100% Polk set up, all being driven by a Rockford 551x 4 channel amp.

Sound Really great for Power handling and price range.

I bought these speakers to put in the rear of my Honda Del Sol. The woofers fir in the OEM brackets though I had to drill a matching hole pattern. No biggie there. Figuring out where to put the tweeters were another issue. I am always hesitant to put holes where there were none before. To that end, I ended up buying a used set of panels that hold the OEM trim and drilled holes in them for the flush mount option. This put them pointed at about the shoulder.

Actually installing the tweeters was a bit challenging. Popping the tweeters into the flush mount housing required an extraordinary amount of force and I slightly dented the grill on both units. Once they are in, good luck on trying to utilize the swivel feature to aim them, They aren't moving.

I am running a Kenwood KDC-HD545U CD Receiver which provides a fair amount of options for sound levels. Sitting still, I can make the system sound real nice. With the top off and windows down, I start losing the bass and if I crank too hard to get it back, the highs start getting tinny. A small sub might help the issue but if you are familiar with this car, there just isn't a lot of room to work with.

For a typical installation, I figure they would be real nice, providing a lot of sound without a lot of power. The Kenwood unit is rated at 22 watts nom and will seems to do ok as long as you don't crank it up incredibly high. At lower volumes, you can tweak the controls to provide a good range of sound without losing clarity.

I would consider these for a regular hard top car but would steer somewhere else if I had to upgrade a convertible or targa again.

I bought these hoping to get the same kind of sound as my Polk monitor 70's I have at home. This did not happen. These are the first Polk speakers for car audio I have ever owned I and I am a little disappointed. It is more my style of listening that make these speakers not work, I like it loud! My problem with the polks is the tweeters get over saturated quick at high volumes and cut off. That really bothers me on a good song.
Long story short, they won't work for me.

These speakers are my latest puchase from Polk. I've had four other occasions to buy speakers from Polk and have come to believe they represent excellent value for the price paid.

Two sets of these particular speakers were installed in my boat with an amp and sub-woofer. Even the installation guys were impressed with the audio quality (I think they are tough to impress). In any case, they sound great to me and I'd recommend them to a friend.

Reasonably priced and sound really good, even at loud volume. Clear highs and mids, decent lows. Also was able to fit these in the stock locations which previously had 5.25 set. Would buy again.

Lets me start by stating these are my first set of Polk's. I was debating between these and some Infinity Reference component or Kappa Coax. I have them in a 98 Accord being pushed with 75 watts RMS. Overall they sound good but not as expected. Mid bass is ok. Maybe I am dreaming but I really thought they would sound better. The amp also pushes a set of Kenwood 5 way 6x9's on the rear deck. The Kenwoods totally blow these away...maybe because they are 95 db vs 91 or 92 on the Polk's. Basically the Kenwoods are twice as loud. I have to compensate by turning gain all the way up on the Polks and to about half on the Kenwood's, then set the fader to F 3 or 4 to get a decent soundstage. Problem is then my Kenwoods are way under utilized. I dont have a sub yet so the 6x9's provide the bass in my setup, hard to do when you cant push the speaker or all you hear is sound coming from behind you...This is not something I expected when I was shopping. All things equal I bet the Infiniti's would be louder as they are 2 ohm so they would be sucking 100 watts RMS out of my amp. Just some food for thought...I probably should have thought of this when shopping but, oh well, I didn't. Once I get a sub I hope to tune to a sound that makes me completely happy. Till then...

I heard these speakers from a retail store and really liked the way it produces bass, mids and highs. After ordering it sounded a bit flat but after 2 months of use, it is almost broken in and sounds great. Good speakers for a decent price!.

I have owned these for a few months now and I couldn't be more pleased with them. Very sweet crisp highs not harsh tin like highs, must be the silk tweeters!

I bought this set of speakers and the clarity is superb. I put it in a Nissan Pathfinder with the matching db6501 in the rear. Powered off an Alpine MRP-F600 provide more than enough power to drive these speakers. They get loud enough without hurting your ears as long as you set the crossover on -3db. Easy install as well. The only thing I would say is I wasn't too fond of the options of tweeting mounting. I prefer if the tweeter didn't have a housing on it so that I could put just the tweeter in the stock location. Overall DEFINETLY RECOMMEND THESE!

These speakers are awsome...stand alone...and I have used these next to MB and Diamond...they are way better

I had recently put a pair of db521's in my overhead soundbar, but they just weren't loud enough while driving down the road with the top down. Then I read that the sub portion of the db6501 would fit within the hole in the soundbar that was originally made for a 5-1/4" speaker. The 6-1/2" sub fits perfectly without any cutting. Then I was able to easily install the tweeter and crossover on the surface of the soundbar. I only had to drill a couple of small holes for the wires and screws. I then moved the db521's up to the dash location, although this required some cutting and a new metal mounting bracket. I also added an Alpine MRP-M500 amp to power the whole thing. It all sounds great, but it's still a Jeep. It's hard to find something that will sound awesome at 70 mph with the top down. But this is the best I've found so far. Especially for the price.

I was looking for a decent set of 6.5 components for my trusty 2002 Subaru WRX. The problem with my Subie is very shallow doors. I chose the Polks as the best speakers that would actually fit in my doors. Mostly I listen to classic rock, and the Polks are great for that. They have a balanced, smooth sound that is good for most music. They do produce good (but not great) bass, much more than my doors can handle. The only music I find they can't handle is very mid-bass heavy groups, such as MGMT. On such music the speakers bottom out and end up sounding like crap. This problem can be reduced by drastically altering the EQ, but that has drawbacks, too. These speakers are probably best for most rock, jazz, and even classical. I am not sure they would hold up for hip hop and rap.

I have yet to amp these and am running them off my Pioneer AVIC-X920BT double din HU and I am very pleased with them. Clear sound with a nice wide range of sound. Bass isn't that crazy but with any component a sub is ideal. Highs and mids are great. I would buy again. These are my only speakers in my 370z and the sound is fantastic even without an amp or subs. Two thumbs up.

Picked these up because my stock speakers had gone out. Great replacements, only issue I am having is that my driver side speaker and tweeter have disconnected once already. I'll have to go back in there and solder them so they don't come apart again. Great speakers for the money, don't really need to use the Xover to boost the db's. Especially if you have a stock stereo. I would suggest these with an aftermarket stereo, EQ, and and a couple amps. One for your mids and highs, and an amp for your sub. Will be buying another set soon to set up the rear doors.

As a Canadian, I was looking for the best deal shopping in Canada for these component sets. My first quote was $279 CDN, next quote from C********* for $220 CDN, then went to Ebay and found these through Sonic for $99!! Even with the shipping I was still ahead of the game. Anyhow, so I decided to buy 2 sets of components for my 2000 Jetta. I replaced my existing stock speakers with these, juiced them with a 5 channel Alpine PDX-5 amp at about 120 Watts per channel and they are nothing short of incredible. Sweet, silky highs and great mid range. The fifth channel on the amp is a dedicated mono channel for a 10" nakamichi sub and my HU is an Alpine X001 connected to my ipod.

The only thing during installation, I couldn't use the provided spacers, I had to buy those separately.

The only negative I can say is I have to be so cautious with my hearing. I'm finding, with no distortion at loud levels, and such incredible dynamic range, I'm always cranking my stereo up to dangerous levels.

For this price you simply can't go wrong!

installed these in the front doors of my dakota quad cab with a set of kenwoods in the rear doors. have a 8in sub behind the rear passenger seat. Polks and sub are amp driven and kenwoods are deck driven. Honestly...don't really even need the sub. The polks deliver comparable response imo. Wish I would have put another set of 6501s in the rear and forgot the sub. great speakers!

I have purchased from this company several times, and have yet to have a negative review. A+++

I bought these about 6 months ago and was blown away how good the clarity was when you turned them up on and amp or on an aftermarket cd player. The only draw back I found on it was that I blew one of the tweeters and I know that I didn't exceed the recommended RMS wattage. But hey I play my music loud for long periods of time, and maybe they needed a break lol. Overall I definitely would recommend these.

I put these in my 2002 Subaru WRX. They are powered with the deck and sound good. I'm assuming they'll sound much better when I install my amp. I've heard better component systems, but not for this price. A built in crossover would be the only thing I could ask for. I replaced a pair of 6.5" Pioneers and the OEM factory tweeters. What a difference!

have a set of these in my 2004 350z, front are component and rears are coaxial. they are being powered by a JL 500/4 they sound amazing. they're not too loud, have good midrange and are very clear. sounds like what the bose should have sounded like.

Bought these six months ago and installed in a 2004 Avalanche after my daughter blew the stock ones. Installation wasn't bad. Had to drill a little bigger hole for the tweeters. Also had a make a spacer for the woofers to have them seal tightly against the door panel. Used Velcro to attach the box inside the door frame so I wouldn't have to drill new holes. Was able to use existing covers so you would never know they weren't original equipment. Sounds great. Clearer at louder volumes than the stock speakers and my daughter hasn't blown these!

The speakers will amaze you at how good they are for the price. I am currently running these off an aftermarket deck and they sound phenomenal.

The highs are crisp and not too harsh, and the mids to mid-lows are punchy and full. No regrets at all.

i have 2 pairs of these components hooked up to an SPL Gorilla 1200 watt 4 channel amp. It is the perfect audio combination. The midwoofers hit amazing mids and the tweeters hit amazing highs that balance with the rest of the sound and they don't leave your ears ringing. I would recommend a subwoofer for the lows, but that may just be my obsession with bass speaking.

All the reviews are right about the highs/mids - they are awesome. I have the crossover switched in the middle (not - or +) and the treble on my head unit is set pretty flat. You may want to set the switch at -. My VW supposedly used a 6.5 inch driver but when I took the old one out of the car, they were bigger and I lost lows going with this speaker. When i turn up the bass way up on my head unit to compensate, my head unit distorts sooner than it should and I don't get the volume I'm looking for. Maybe an amp is one solution. I have a subwoofer installed as well so I'm okay with the loss of bass. The drivers seem to take a while to break in as well when it comes to the bass. If you don't have an amp or a subwoofer, you might want to look at a lower wattage component set to get the full range easier with head unit power.

I am a huge Polk fan- always have been! And these speakers live up to my expectations! I have had Kicker speakers before, and I have also had JL speakers too. I have to say- they are right up there with the best. The Highs are smooth and pristine, the mids are just right, and the lows are tight and smooth. I love em!

I settled on this pair of components due to price and quality balance! They sound great, and I love the component features. Great representation of all range of sound, especially bass. Have owned those for around a year and enjoying them so far! I had to make custom brackets to mount those, but that's just was my idea for very solid installation and sound proofing.

Installed these in my fj cruiser front and rear and the sound quality rocks! Clear, crisp highs with some really tight midrange. Can't beat it for the price! Compliments the 2 JL audio 10's I have for bass.

These are worth every penny and more.
Highs are super awesome.
Mids are exceptional.
Bass is ok (do not rely on these for bass- get a sub or pair of 6x9).
These gives so much detail. it is sometimes scary.
Professional grade.
Polk audio does not play around! they are legit.
I get complements all the time about the clarity of my music.
Very good for any type of music (Hip Hop. Rock. Oldies. anything really!!!)

Put these on my Eclipse EA 4200 running only 60 watts RMS per channel and they absolutely scream! It is almost comical how great these sound even at the highest volume levels. I couldn't have asked for better sounding components for the price :o)

made a huge difference from the stock speakers i was running. great mid bass. two sets in a 04 trailblazer and they sound very nice.

I have 5 sets of Polk Audio speakers on my boat, 2 sets of 6x9s, 2 sets of 6.5s and the last set added was the components. And the components are just as good as the 6x9s. In fact by next summer the 6.5s will be replaced with 2 sets of components.

I bought these to replace some worn out Sony components, and I have been very happy ever since! The tweeters are crisp and clear, the woofers almost kick as well as my 6x9's in the back! A very good product that would be helped greatly with an amplifier. I had to use double-sided tape and super glue to hold in my tweeters, and had to drill new holes in my door panels, as the woofers use 4 screws (my door panels had 3). Overall, I am very happy with these!

Love em. Great highs and mids. Get a sub for bass. Marine certified so they will last a long time. Cop a set.

First of all, i received the package on time. The speakers sound great. Great bass/midbass and above. Tweeters aren't harsh at all. Would recommend to anyone.

polk has always produced quality stuff
but not this...
this is BETTER
unbelievable sound
decent lows and the tweeters arent annoyingly sharp

This component set is too true to hear. The highs tweeters are very clear and crisp you won't mess a tone. The midbass 6-1/2 woofers are very nice, they're not deep bass, but they push very nice clean bass that is good for a component system.

these things are the perfect componet systme if you amp them if you dont they will soun d like stock factory speakers. but when you even put a small amp behind them. they are dead on and are so accuarate. just perfect i have two sets of them in a single cab truck, not needed but i just cant get enough of them. you wont be unsatisfied with these things.

I believe that infinity along with a few others are better then these.

sound good on an aftermarket stereo. wanting to get them on my amp and see what they will sound like

More bass would be better, but very nice speakers.

I would not recommend these for listening to spoken word, news or talk radio. Music they sound fine, but otherwise these suck. I will be replacing them.

Worked awesome to replace stock tweeter location and fit perfect.
