Blaupunkt's GTx 663 DE 6-3/4” speakers offer the sonic clarity you want for your music at a budget-friendly price. They're a great option for replacing factory speakers that have lost their "stage presence."
Each GTx 663 DE speaker features an injected polypropylene (IPP) woofer for a lively response from your mids and lows. The 3-way speaker design also includes a 1" Mylar dome tweeter and 1/2" super tweeter which deliver all the details and ambience in your music. The speakers' low profile enables you to install them behind the factory grilles in many vehicles, but they also include stylish protective grilles for custom installations.
The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.
Great economical replacement for OE speakers. Excellent sound quality, even at loud volume levels.
This speakers sound horrible. One of the speakers start making buzzing sound after a few songs, like something was loose. I disassemble panel to check if some screws was loose but it was not the case.

Seem like nice speakers, they pump out the bass with little rattle. Easy to install.
Pros: Good quality, nice bass.
Cons: Nothing I can think of yet.
Bought these to replace my factory door speakers in my 05 corolla. I must say these do pretty well for the price,,, But after having them for some time now I have noticed that they are really lacking in the Bass department. I now these are only $70 and I know not to expect to be blown away but sound quality but the Bass is really lacking and at least to my ears its the same if not a tiny bit better than the factory paper one I took out...... I will be swapping these out very soon for some Kicker 40CS674 6-3/4" speakers. A friend of mine has these and they hit a lot harder than these Blaupunkt GTx 663 DE's .... But if bass in not to high on the list for you and you want a good speaker than does mid's and high's very well with okay bass then I would really recommend these. Turn the music up and PLAY ON!
Pros: Very good mids and highs. Solid well designed housing and construction. Price is really good
Cons: Really lacking in the bass department.
Install was very easy and they sound great in my Rav4
Good speakers. Highs and miss are good. Bass response is weak. I suppose that for the size, the speakers are a good buy. Well made and easy to install.
I installed these in my mom's chevy sonic (which didn't come with rear speakers). The speakers sound great with the stock head unit. My mom is very happy.
Pros: Good sound when paired with the stock head unit.
Installed 4 in an 03 Vibe. Installation quick and easy with mounting bracket and harness. Speakers not as 'bassy' as OEM, but sound great with original stereo and amp. Mids and Hi freq sound clearer, will be trying a Pioneer HU in next. Would definitely recommend for the price.
Pros: Installation ease Price Sound
Cons: Too bad the door panel covers these great looking speakers Light on bass response
Installed in an 05 Sentra, Had to open up the mounting holes slightly - used a step bit. Installation sheet helped IMMENSELY, spot on instructions. I never knew I had fold- down rear seats until today ! The included wiring adapters made life a whole lot easier.
Pros: very good form fit and function
Cons: mounting holes askew
Once again I have trusted my choice to Crutchfield and one again, they have come through. I had them professionally installed on my 99 Jag. With prior experience of Blaupunkt I knew I had a relatively inexpensive but good buy. I knew these would be good for my Jag, and I wasn't wrong. It seems the sound is better with the volume set at 14 or 15, rather than cranking them up past 20. I tried all three forms of music that is installed on the Jag. Radio, cd, and yes, even a cassette. The sound level was the same for all three Even with the HK installed system, I was literally amazed at the clearness of the cassette tape and gave it two thumbs up. I then picked out a good ol rock and roll station and set the bass a little heavier, The speakers thumped right along and I could feel the air moving around down by my left leg. I jacked the volume up two, and let it roll. I then faded the speakers to the back ones and cranked it up more. I was not unhappy with the results. Having passed that test, I then moved on to a cd. AC/DC and "Thunderstruck" My favorite foot stomping and head noggin music. I cranked up the volume and bass and once again I was not disappointed as to the sound. I was raised on rear deck speakers and have to admit that the speakers in the doors also provide good sound throughout the car. All in all, I rate these 3 ways as a good buy
Pros: good sound, good quality
Cons: none at this time
Sounds ok highs and mids sound great not to much
Cons: Not to much bass
Crisp highs and tight bass make these a good buy for the money.
Pros: Good tight bass Accurate bright highs
I bought the Blaupunkt GTx 663 DE speaker to replace the blown out woofer in the driver's side door on my '05 Prius with Navigation and JBL package. The speaker is the correct size, but the screw holes do not line up. The existing speaker had four ears to mount to the existing bracket, the Blaupunkt speaker does not. I'm disappointed with Crutchfield because the web says says this will fit using the existing brackets, but it does not. I will now have to search for an adapter bracket.

Nice quality, fit well and sound great in my `06 Express van front doors.
I bought these speakers to replace the front speakers in my Camry. They are good looking speakers and seem to be well built. The install was pretty easy (about an hour). The only complaint I have is that these speakers distort when turned up above half way when the speakers are rated a lot higher than my head unit is. Other than that they sound pretty good at lower volumes.
Pros: Sturdy, Good looking,good highs
Cons: Distortion, Lows

Size Classification Note: Some manufacturers, including Blaupunkt, call this size speaker a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size woofer as a 6-3/4".
