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!

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.

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.

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!

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.

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.

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.

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!

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

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.

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.

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.

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.

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.

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.

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.

Worked awesome to replace stock tweeter location and fit perfect.

One word....Perfect that's the only way to describe these speakers.

i have this speaker on my s2k and they fit just perfect even the tweeters fit excellent. the sound is amazing especially with the top down.

Excellent products...
