Alpine CDA-9831R is a very good choice to increase the quality of your car audio. In my opinion it looks quite good, and what even better is you can match the illumination to your car's dashboard lighting through a range of 512 colors. But what i like the most isn't the looks, but more to its features. The 3-Position HP/LP Digital Crossover and 4-band parametric EQ features is very useful for upgrading the quality of your car audio. Those features can make your car audio producing more focus and better sound quality. What even better is the 4-Channel Digital Time Correction feature can make the sound produced by your car audio feels like coming from the center of your car's windshields. So it feels like you're watching a live concert. Overall i think Alpine CDA-9831R is very good in producing a good sound quality in your car. But i suggest you also use aftermarket speakers, subwoofer and amplifier also get help from a good car audio installer so u can draw this Alpine CDA-9831R's potential to the max.
My VW is now fully wired up to an Alpine CDA - 9831R - which I love!
My favourite thing about this stereo is the fact it is great looking, very modern and looks great in my car. The front of the stereo can be place at and angle, of different settings which means not only is it much easier to see and use for your own personal preference, it will fit and look great in many different dashboards. The screen is a great size, not too small. You can adjust the visual settings too to show different colours, text etc. I have matched mine to the rest of the interior lights in my car - blue and red!
The stereo comes with a manual, however it is very easy to use and once you have a look at the options it is very easy to change the settings too.
The performance of the stereo is fantastic too, much better than stereos that I have had previously. The stereo has a built in 50watt x 4 channel amp you also have options of connecting yout own sub at the rear of the stereo - I have not choosen to do this. To improve your sound and listening pleasure even more you can attach your Ipod, MP3 player or connect to a bluetooth headset.
Overall I give this stereo a 9/10 - It looses one mark as it is not the cheapest stereo on the market, however I believe you get what you pay for!
This is a great stereo that has a lot of capabilities. You can choose from various angle for the face plate at the touch of a button, Built in mp3 so you can have a lot of music on one disc, and my personal favourite i added an ipod adapter from apline which allows me to control the ipod from the stereo and puts a nice alpine logo on my ipod too.the colour range for the buttons is good too, a negative is that the materials the face plate is made from will cause vibration when titled out this is especially noticed on a car that vibrates a lot with engine running. My brother purchased the lower down version of this stereo and the face plate plastic was much better with no vibration at all.
The Alpine CDA - 9831R is a great looking, great performing piece of car audio which brings some seriously great audio features inside your vehicle.
The faceplate is able to be 'angled' to a number of settings allowing it to fit perfectly into dashboards which may be sat on an angle or where the head unit is mounted lower down. The colours on the main 4 buttons can be selected from 512 different variants allowing the illumination to blend in with that of any dashboard perfectly.
The screen is large and very clear, which makes adjusting the settings both easy and a pleasure.
Sound is provided via a built in 50watt x 4 channel amp and there are 3 different pre-outs allowing different amps to be connected for front, rear and sub applications. Filters are available to send the correct bands to the correct amps & speakers and a 4 channel parametric equaliser is included allowing fine tuning of the sound. One of the best features is the 'sound-delay' which allows you to put a tiny delay on each seperate speaker meaning the sound from each arrives at your ears at precisely the correct time providing crystal clear audio.
I-Pods can be connected via an adaptor and bluetooth hands free is also available with the correct bit of kit.
This sterio is superb! Ive had it for a while now and im really pleased i decided to go with this one. I had looked at the sony range, but they sounded very 'tinny' in comparison in my opinion. The alpine gives excellent output wattage and has a good range of connectivity with it allowing you to conenct a whole range of other audio equipment to it. The built in MP3 player is obviously an added bonus, and allows you to have hundreds of tracks at once rather than having to find somewhere in the car to store all your cd's! also stops them getting nicked if the car gets broken into! but thats beside the point. The only downside i would say is the slightly dated screen which doesnt look as good as some other devices out there which have some nice displays on while your favourite tracks are playing!
