Pleased with the product and the price is great in comparison to other sites.

Good speakers

Bought these to drive off HU and was not happy. Decided to put in rear and put CDT coax in front and drive with Kenwood 4 ch. amp. Well once I drove them with amp I discovered why I did not like running off HU. They are power hungry and once I had enough power to them combined with CDT's in front they sound unreal! I have always liked JBL and continue to like them. Just make sure you drive these with amp and give them the juice they need. If you do this they will perform.

awesome

These speakers are very clear with great highs. Don't think twice about it buy these if your on a budget

good 2ohm speaker

I needed a 2ohm for my OEM amp.
This is a good 2ohm at a good price

Nice Speaker, Just feed it some power to be happy.

I got this speaker to replace the cheap 2ohm rear speakers in my 2014 Nissan Frontier. Install was very easy, but had to cut factory wiring to connect. Make sure you get the polarity right so you do not have to remove the door panel again. Sound it very nice with factory radio, But add a amp like i did and you will be much happier.

Best Buy EVER!!

These are high end speakers,worth much more! Thank you Sonic Electronix for making them affordable for me I love mine they sound amazing and I also have the tree way 6X9's in the rear deck! It's a win win.

awesome

Great product very clear and loud will definitely recommend to others

JBL GTO638..great value

The sound is very clear. The speakers make my radio sound so much better. I would recommend this product

Great Upgrade

I bought 2 pair of these to go in my 2010 Chevy Avalanche to replace the "premium" Bose speakers in the doors. I was told I needed 2ohm speakers if I panned on using the factory head unit because that's what the factory speakers were. So I tried them and they sound amazing. Much better than those Bose speakers. I will eventually put an amp to them in the future but for now the head unit is doing a good job and these speakers really made the music come alive.

Jbl gto638 crystal clear

Very easy install. Running them at 50 rms they play extremely loud and I love them. JBL-enough said

Great sound

Great sounding speakers. Blows away the factory garbage. Factory speakers would distort at just over 3/4 volume. Needed more sound to compete with the pipes. Now I can hear the stereo over the pipes clearly. Don't forget the adapter rings when buying.

Great Value

Great Value Product Works As Stated Thank You Much

Great replacement for OE speakers

I bought the GTO 638 to replace rear door speakers in my 2006 Hyundai Tucson. I'm still using the factory head unit. These are a big improvement over the factory originals. Sound quality is much better. If and when I need a new head unit, I know I can depend on these speakers to handle it. I highly recommend these speakers and their price was reasonable.
Pros: good sound quality
Cons: None

Get ready to rock

I have owned these speakers for about a month now. I received them from my wife as a xmas present. Found a youtube video on how to install them in my Chevy Impala. The speakers sound great. Tremendous high end. The only downside that I have found so far is that these speakers do tend to draw some power to drive them. I am driving them with the stock Chevy radio and they need more power. I can't wait to buy some JBL 6x9 inch speakers for the rear deck and a new radio to drive them. Then my system will really ROCK!

JBL!

these speakers when not amplified sounded really the same as my 40 dollar sony xplodes. i wasnt really impressed... UNTIL i got an amplifier to amp them up. OH MY GOD. these speakers are crystal clear!! really good bass response also! make sure you give these bad boys the juice they deserve! ;) they will treat you good

Horrible

Have already replaced these speakers as they blew shortly after being installed. They were professionally installed and were not hooked up to too much power. I don't believe these speakers are not rated properly as far as the power they can handle.

great price awesome quality

Fully recommend these are great speakers for your back doors.

Rockn!

I would recommend these speakers for 2 reasons. I bought them without ever hearing them and they are a JBL product pretty much the only speakers I would ever own. If only Yamaha would now make car stereos the world would be a better place lol.

Love these.

Great speakers for the inside of my boat. No problems installing or listening to them.

Great Value

Great Product Was shipped Fast and Works Great Thank You

Jbl

I like it I'm happy thank u I will order from u guys again

Replacement Speakers

I purchased these as replacement door speakers in a 2001 Silverado. Perfect fit. With just the factory HU they sound great. The more power the better they sound. You will not be disappointed with these.

very clean

nice product the plus one technology makes the bass even better the highs are super clean. and adjustable

Just ok

Kind of tinny sounding and highs tend to squeal off pitch. The mounting rings didnt work and they provided no cables in the package. Not worth the money in my opinion.

Great value!

These are exactly what I expected from JBL with a very low price. At $55 the performance far exceeded the price. These were used as factory replacement front door speakers in a 2006 Impala and with the factory stereo, a JBL amp, and 2 6x9 JBL rear speakers. The system is amazing and the buying experience from sonic elec was awesome!! I will purchase from them again!

Great tweeters

The sound from these are amazing ....I had these with a 10w amp and a 60w rms amp ...it sounds good with 10 but 60 is fantastic ....soloooo clear ...you will not b disappointed!!!

very nice speaker, at a great price

these speakers are easy to install, with all hardware provided. They sound so much better than the stock speakers in my honda accord. The bass is pretty good for this size speaker but the highs are great!. Love them

JBL GTO638 vs polk audio dxi6500

I bought 2 pairs of these bad boys for my car. They sound awesome, great highs, enough of mids and you can get some low's but not too much. I have all 4 speakers hooked up to a 4 channel 1000 Watt amp at 125 rms for each channel. They are pretty loud when i set my volume at 15 when the radio can hold up to 50 on the radio. After 30 i get distortion. I'm really happy with my product and i do recommend these speakers and it will sound even sweeter with an amp. By the way i also own 2 pairs of the polk audio dxi6500 and i was disappointed how i spent more $$$ on them and they dont sound as good as these JBL. 2 tweeters went out on my polk audio's and i was stuck with only mids and horrible low's. they couldn't handle the power of the amp and it sounded lower than the JBL's.

Fits my Jeep 95 orvis

I originally got the jbl gto 529's and they were to small... No where near the stock sound I had so I sent the 529's back for the GTO 638's!!! Some lucky person is getting an open box discount on a set of gto529's. The 638's are more than what I need to replace and exceed the oem premium infinity's.

Do yourself a favor if you are a novice. Make sure to call them to make sure there are adapter mounts and quick connector/adapters for the wiring. It makes the job way easier. I found that out when testing the 529's to see if they were going to be lound enough. Happy shopping

Easy fit

I have a 2000 Chrysler 300M (LX body) with Infinity II sound. This requires front door speakers that are 6 3/4", with 2 ohm resistance, and are expensive and hard to find. I used these JBL's and they bolted in with no hassles whatsoever. Sonic's pricing was very competitive, and delivery was fast, as promised.

great value, great sound

The more power for these the better you will like them. Can't go wrong with these.

Pretty good on factory amp

I have a 2010 Chevy Avalanche with the "premium" Bose factory system which is not so premium. I needed a 2 ohm 6 1/2 or 6 3/4 speaker to replace my door speakers cause that's what came factory so I went with these. Bought 4 (2 pair) for all my doors. Man they sound loud and clear for being run only on the factory amp and head unit. I don't see a need to add an aftermarket amp at this point.

WOW

recently bought these mated them to the same 5.25"'s and put them on a gto1004 from JBL... these sound (to me) better .. cleaner, deeper, all around than the 750$ focal's i was going to use. running them on 150W rms and they love it. for the money i couldn't ask for a better sounding speaker, keep up with the JBL 1224's i have running 1100 watts each! makes the BOSE system i had in my avalanche sound like childs play. thanks sonic for stocking a great product... huge jbl fan now

GOOD SOUND

Sound good, the best you can buy. 5 all the way.

Good speakers.

I would recommend these speakers to anyone who needs to replace there factory 6 1/2's. Great midrange and tweeters.
Bass is pretty good also.

workin good for me

I put them in my 2001 chevy silverado 1500. No problems at all. Easy to install. Very good speakers.

Decent

Old tundra speakers went out put these in to replace stock speakers and they are good. Just hard to screw in the stock housing and needs to be tight seal against the housing but not bad heard worse heard better.

Yo

Bro, I heard these in my boys whip and man did they slam all by themselves. of course, they can't hit lows very well because well they're not supposed to but 4 of these lit up our ear cavities like it was the forth of july. Slammin back some nattys, + these speakers... Our life is bro.

JBL is the best

I have had several JBL speakers but these are the first for a car. I counted on them to be good and they are. For the cost, the sound is wonderful. The base- which all important- is superb. These would be a great upgrade for any car.

Yes- but these

Dropped these in for the rear speakers in my Honda Element. I had to modify the brackets with a sawzall, but it's part of being a man.
You won't regret buying these speakers in the 60 dollar range.
I have it hooked up to a pioneer 5800 series.
Should have used in my fronts but I opted for components instead.

Great vocals, mid bass and build quality

Installed a set of these in the front doors of a 2006 Impala LT, powered by 2channels of a 4-channel amplifier. Very clean, clear and LOUD vocals. Mid bass was tight and solid. After mounting the included bracket to the speaker, had to drill (2) holes in the door. The top screw and location is reusable.

Awesome speakers!

Replace the OEM speakers in my sons Rav4 with the JBL GTO638's. What a transformation in sound and clarity. Don't need to waste money on subwoofers. The speakers are the best value with fast shipping from this vendor!

AWESOME SOUND

I NEEDED SPEAKERS THAT WILL TAKE MY AMP WITHOUT ANY DISTORTION. CLEAR SOUND AND BASS. THEY ARE BETTER THAN THE KICKER AND BOSE FACTORY SPEAKERS I HAD IN THERE SINCE I BOUGHT MY TRUCK 14 YEARS AGO AND SO FAR THESE ARE PERFECT FOR THE SYSTEM I RUN..

Middle of the road

I purchased these speakers with high hopes. I at least expected them to sound better than my stock speakers as they are only two-way. I must say that I was disappointed. the sound quality was not as good as my stock speakers with the exception that they could handle the wattage better. They don't have much of a low end response either. All in all - I would no recommend these speakers.

Good product for the price

These are ok speakers but I did have some issues with the first set I bought cause one speaker was already blown straight out the box so I ordered another pair and there ok for the cost on just a head unit but I recommend running them at 2 ohms on a power amplifier to get the extra kick

loud and clear

i got 2 sets of these jbl 2 ohm speakers and matched them up with the new sony mex-xb100bt. it gets loud, has pretty good mid bass and takes every bit of the decks power. sonic did a smd amp dyno on the deck. the deck made over 60watts rms at 2ohm. the jbl also came with things such as adpaters, covers, screws and everything else needed. great speakers for a great price

Perfect Speaker!

So I bought these after months of searching and reading over reviews before I finally pulled the trigger on these and their 6x9 counterpart the 938s. I did get these for a 03 Ford Taurus however my doors only fit 6x8s which led me to purchase adapters for the front two speakers. After hours of fabricating the plates to fit these speakers. Not the speakers fault tho but these were exactly the sound I was looking for. DO NOT HESITATE TO BUY THESE. I was extremely happy with these!
