The Alpine CDA-9830 CD/MP3/WMA receiver's motorized fold-down face has a clean, stylish look that really makes the multicolor display stand out! Likewise, your MP3 and WMA song titles will look good and be easy to read. The CD slot is concealed behind the faceplate, keeping the internal mechanisms safe from intrusive dirt and grit.

Bass Engine® Plus equips you with some serious sound control tools. Use the 4-channel time correction and 4-band parametric equalizer to create the perfect soundfield for your car's acoustics. Tune the high-and low-pass crossovers, subwoofer level, and phase controls to optimize your system's performance.

Digital media (MP3 and WMA) playback ensures that you'll have lots of musical variety available without burying the passenger seat under a pile of CDs. Instead, you can store a couple of MP3 discs in the glove box. Alpine's MediaXpander™ restores sparkle to music that's been broadcast or compressed — it does wonders for your MP3 and WMA files.

Add an XM tuner and an antenna and you'll be able to subscribe to XM Satellite Radio's 100 channels of music, news, sports, and entertainment. A wireless remote helps you make changes while you keep your eyes on the road. The CDA-9830 will also play SIRIUS Satellite Radio.

Why replace your factory radio?

Two good reasons - sound quality and cool features. A new car stereo offers power that's superior to most factory radios, along with more sophisticated tone controls. And most car stereos offer built-in or optional features that add safety and fun to life in your car, including inputs for your iPod or MP3 player, Bluetooth connectivity for hands-free cell phone calls, satellite radio or HD Radio reception, and connections for building an audio system in your car.

Awesome HU

Written by: Alex from Tacoma, WA on July 5, 2005

Crutchfield Customer Review (What's this?)

Alpine is the best! The sound this HU puts out is great! There are lots of sound customizations, everything you could ask for. The display is dim, but if you move your head to a different angle, or use your hand to shade it in really bright sun it's not so bad. I really don't find myself that annoyed with the display. I mean, I'm driving; I want to listen to great sound, not watch a flashy display. Burning six to ten CD's onto one (I use 192k WMA's, they sound just like a normal CD) is a big plus. All in all a really great deal on a nice HU. I'd give it five stars if it had a brighter display.

Crutchfield Customer Review (What's this?)

Okay, so you might be like Ray Charles when it comes to the display... heck the stock Focus display was hard to read, too. The display thing is the only mark down about this unit; if it sat lower on the dash, that would probably make the difference. This head unit with the stock toilet paper speakers was just incredible. Hmmm, why did I get the Polks? Well, now I know. The level of customization is just incredible on this unit. I just finished the install and have tweaked very little and am sooo impressed. This unit allows for pre-set eq and a couple custom. Also, what I look forward to is setting the time delay feature to enhance the soundstage imaging. This head unit is very user friendly, installed w/o difficulty (Thank you, Marie!) and looks very clean in the dash. The power face feels tough and solid and the layout is logical. Great buy!



Great Price, Excellent Sound!

Crutchfield Customer Review (What's this?)

Alpine says it all to me. When I bought this unit I was looking for something with great power and the ability to intigrate XM into the Head Unit. After reciving this it has been one of the best Head Units I have ever bought. Great basic look and feel but very indepth sound customisation. I would recommend this very highly to anyone with a low budget but one who wants great sound.

Crutchfield Customer Review (What's this?)

OK... so this will resemble the last few reviews... The sound quality is great, buttons are easy to find/use, setup (if you use ipersonalize through alpine) is fairly easy, hooking it up with the wiring harness and kit was a snap (2005 Altima), IPOD interface is excellent (setup and quality), and it has more features than much of the new 05 lineup.


The display is brutal in the daytime. Not just the sun, but in daylight in general (which i get a bit of in Tucson). I was going to have a custom housing built, but I dont think that will even make a difference. If you have really dark tint or if your radio is mounted low on the dash and at a declined angle it will probably be OK.
I dont fit into any of those categories, so I might have to search for another model (but I really dont want to shell out 100 more for it).

The choice is yours but you cant say you werent warned about the display.



Excellent sound and flexibility

Written by: Jacobo from Miami, FL on June 22, 2005

Crutchfield Customer Review (What's this?)

The CDA9830 its a great unit with more features than the one that replaced it for 2005, the CDA9851. Yes, the display could be better if you are into flashy displays, but if what you are looking for is good sound and features to customize it, the CDA 9830 is superb, more so if you consider its price now that the 2005s are out.
The CD9830 has BassEngine Plus, a feature that Alpine removed from the 2005 lineup because (I guess) it was to close to its BassEngine PRO offered in its top of the line units, it also has MediaXpander instead of BBE, a feature only offered in its three top of the line units 9853, 9855 and 9865 for 2005.

With the CDA9830 you get 4 band parametric EQ, factory set EQ curves (Pop, Rock, etc),LP/HP crossover, 4 channel time correction (delay) for the speakers,subwoffer level and subwoofer phase control. On the power side, this unit has the same power ratings as the top of the line 2005 models 50W max/18W rms.
The sound from this unit is great and I like the fact that it is a HU that will allow you to grow your system.
The I-personalize feature in this unit is not very functional because it doesn't allow you to download the settings from a Cd-r to the unit, but then again you have to be in the car to tune your system and a few key punches aren't that difficult. How can you set it up sitting in front of your computer!

Other nice feature is that it has a motorized face with different agle settings that you can control with the remote (you can't do that with the 2005s)

Well, as mentioned in the begining, if you are looking for sound and not for a fancy display the CDA9830 is a loaded and affordable option.



Great sound, poor display

Written by: Philip from Santa Clara, CA on June 10, 2005

The 9830 produces excellent sound quality which can be finely adjusted through the Bass Engine Plus. The 4-band parametric EQ, variable crossover, and MediaXpander are nice features and allow fine tuning of the audio signal. The 4-volt preamp outputs are a huge plus if you plan on using RCA cables.

The display is fairly stylish, but only when you can see it! This was one of my concerns when purchasing this product. It is not completely invisible to read in sunlight, however I must agree it is difficult to recognize. It lights up nicely in darker environments, however this remains an issue whose severity depends on the unit's mouting angle within your vehicle. I wouldn't say it is impossible to see in sunlight, but Alpine definitely could have improved their display design.

I am going to keep this unit because Alpine's sound processor is fully customizable and produces amazing sound. The point of this product is for sound processing and not video, so if you are searching for something nice to look at, then I suggest Alpine's 7" DVD player. Otherwise, if you are driving and focusing on the road while listening to music, I would suggest this product for the advertised sale price.



Alpine goofed on the 9830

Written by: Excelerater from Memphis on May 29, 2005

The display is all but invisable in daylight - I had to send mine back for a credit.
Avoid,unless you only drive at night .

I also own a 9833,which does not have this problem



Display Problem in my car

Written by: MJ from Washington, DC on May 29, 2005

Crutchfield Customer Review (What's this?)

My dashboard slopes upward so the face of the unit slopes upward too which makes it impossible to read the display on this unit during the day. Otherwise I like the unit. Don't expect a problem if you don't have an upward sloping dashboard, it just seems to be a viewing angle problem. I would have expected someone to have known this in advance before buying one though. I had to return this unit and will see if the one for $100 more will fix the problem. Why doesn't someone check these things and include it in the comments for will this unit fit in my car?

Hot stuff, buy this!!!

Written by: ddcyr3 from Maine on May 7, 2005

I was in the market for a new cd player and I have an Infinity sub with alpine amp, so I have heard much praise of Alpine, so I decided to go with them. I was trying to decide if this was worth the extra $50 over the 9847. IT IS! This is worth so much more than 50 extra. I have a 40x4 amp running to my speakers also, and the signal put out is sooo clear, and powerful. It goes up to 35, and at 10, it is LOUD. Sub adjustment is perfect on headunit. 4 band eq is awesome. Spend the extra 50$, or you will be regretting it greatfully.



Thumbs up for quality!

2001 Ford Taurus SE
Crutchfield Customer Review (What's this?)

This is a great unit for an audio enthusiast. Sound quality is unmatched and one strength is effortless delivery of clean, rich sound. CD playback is an acoustic pleasure with accurate and distinct rendering of vocals and instruments.

The MP3/WMA playback needs some getting used to but once you get it, accessing your files is a breeze with the smart folder system. I find that burning MP3 CD's using the Windows Explorer file/directory system is most efficient and is compatible with the unit's folder system.

I give this unit a 4 only because of the lack of bass/treble controls, making sound tailoring too involved while driving, although the units quality does a very good job without any EQ settings. To access the EQ tailor menu requires a complicated sequence of pressing and holding buttons...a strange operational requirement for a unit of such class.

I decided to use only three preset settings which work really good, "Flat", for all CD/MP3/WMA, "Rock" for FM radio "Talk" for AM. Playback of CD's requires no processing because of the quality of this unit. I do use the MediaXpander when necessary for the irregular audio properties of MP3/WMA audio compression though. I did think about returning the unit but the more you play it the more you love it.

A definite vote for quality here and I am keeping it...and "that's my final answer"

Crutchfield Customer Review (What's this?)

this unit has great sound. the display is OK, direct sunlight makes it impossible to see, with less intense light on it its OK, at night it looks really good. sound controls are good but the menus are a little confusing at first, with some practice it should be alright. for the price I dont think anything else will have this good of sound.



Alpine = Amazing Clarity

Written by: ChevyTruckMonkey from Huntington Beach, CA on April 16, 2005

Crutchfield Customer Review (What's this?)

I recently installed this cd player. I have owned kenwood and clarion cd players, but so far Alpine is by far my favorite. I gave this model a rating of 4/5 because the display is hard to see during the day and thus makes it a bit more of an anoyance while driving. Besides that I still have my stock speakers in and the music rocks! Menu's take a bit of time to get used to, but this cd player is awesome. Although you could save some $$$ and get another alpine with just a few less bells and whistles.



Good product

Written by: cs_joe_cs from WA on April 8, 2005

Easy to read display. This thing has quite a bit of features, so far I haven't had any problems. It was a bit tricky getting used to how to control the MP3 discs, because you would think that you use the skip and back buttons, but it works better if you use the volume knob. Once you get used to it though, it is pretty easy to use.

I got the AUX input installed, and so I can plug in my iRiver h320, my only complaint is that there is a little bit of noise when you use the AUX input, not sure if it is my mp3 player or the deck, but I find it I turn the volume all the way up on my mp3 player it gets rid of the noise.

My friend has the 9831, and the only differences are that you can change the button colors on the 31, it has a bigger screen, and some other small stuff, but are far as sound quality they are EXACTLY the same.

Great deck, especially for the money.



Great sound, POOR visibility

Written by: Matt from Trinity, FL on April 2, 2005

I have mixed feelings about this head unit. It is your normal Alpine unit which is to say it has world class features and sound. However, you can barely see the display from anywhere in your vehicle. There is no dimmer to make it brighter and if you are in any amount of sunlight you can't see anything. This deck would be fine as a podium deck at an SPL soundoff when all you need to see is the play button, but not in a car dash where lighting is never ideal. Dish out the extra money for the CDA-9831 and save yourself the squinting. There are going to be reviews after this that will say I'm crazy, but go check the deck out at a car audio shop and you'll thank me for saving you the hassle of exchanging it.

this is a very nice head unit at an even nicer price. alpine name and quality. all the features you really need and then some. simple, clean design. simple functionality. sounds simply amazing. easy install. would look great with any interior. compare this units specs with any other at the same price--you will find it almost impossible to beat. unless you feel like you can't live without little swimming dolphins, this is the head unit for you.



Alpine Quality

Written by: Mark from Petersburg, VA on March 31, 2005

What is there to say but this is a great unit. It doesn't have all the flashy display features, but this is no out-of-date unit!

This unit is all about reproducing great sound with quality. It will play MP3, WMA, CDs, Radio and SAT-Radio, and an external Aux device. It's got 4v pre-amps for all channels for your amps. It's got digital time correction and the media expander to really make your music come back to life. It's got a bunch of EQ settings and the ability to customize your own EQ settings.

One feature I love the most is the built-in low and high pass crossovers. With the crossovers on, the car speakers always have plenty of power and don't distort to bass while the sub woofer gets nothing but the low frequencies.



Alpine CDA-9830 Review

Written by: Hotrodguru from Houston, TX on March 26, 2005

Well trying to decide whether to give it 4 or 5 stars was the hardest part. I received the unit yesterday and installed it. Didn't want to write a review yesterday because I still had quit a bit to learn about the unit. I've decided to give it 5 stars, this is based on the fact that right now I'm VERY pleased with it and still haven't learned all the features. It did take awhile to learn how to navigate the folders and sub folders on my MP3 CD's but now that I've figured it out I must say it is very ingenious and clever. By far one of the best features. As for the sound, incredible. Gonna go sit at a coffee shop tonight and learn all about the crossover and custom features. One thing I kind of don't like and maybe I just haven't found is a simple way to adjust Bass and Treble. I'm sure this is due to the fact the tuning is so precise and uses User EQ settings. The 7 factor EQ settings are quite nice though.

I would also like to say that this was my first head unit install and way too simple. Crutchfield Technical support made it very easy and explained in depth a few questions I had. I actually called twice, the 2nd time was to make sure I wasn't leaving out any steps. I just couldn't believe that it only took 45 minutes from start to finish.

Thanx Crutchfield, Guru

Crutchfield Customer Review (What's this?)

I just installed this in my '01 Ford Ranger, and it is great!! It takes a little time to figure out all of the options, but after getting them set up, it is a super product. The instructions for installing it are clear and easy to follow. I like the ability to play MP3s, putting 200+ songs on one cd beats playing 10 separate cds. I was most impressed with the sound. I used the stock speakers, but the sound was so much clearer, and delivered a true stereo effect. Until I installed and used it, I couldn't imagine the difference, but once I did, it was evident. I can't recommend this product enough, it is a quality base unit. And if someone as electronically challenged as I can figure out the wiring harness set up, anyone can. I kept the old unit, 'cause when my Ranger goes, this unit stays...

Changer Controls
Clock Display Note


Selectable Faceplate Angle: In addition to the standard faceplate position, there are three preset faceplate angles for you to choose from.

Blackout Display Mode: When the Blackout mode is activated, the display turns off to reduce power consumption. The additional power made available by turning off the display helps enhance sound quality.

Bass Engine Plus: Bass Engine functions provide control over your system, so you can tailor the sound to your personal tastes. Bass Engine Plus includes the following functions:

  • 4-Channel Digital Time Correction: The time correction feature allows you to create virtual speaker positions by delaying the signals being sent to the speakers closest to you. When the correct delay times have been entered for the front right, front left, rear right and rear left speakers, all sounds reach your ears at the same time, providing optimized imaging and frequency response.
  • 4-band Digital Parametric EQ: The 4-band parametric EQ lets you select a center frequency, then adjust its output level and even the "width" of the boost or cut for precise system tuning. The parametric EQ offers a selection of 4 frequencies and 15 center frequencies: Band 1 (40Hz, 60Hz, or 90Hz), Band 2 (100Hz, 150Hz, or 200Hz), Band 3 (500Hz, 700Hz, 1kHz, 2kHz, 4kHz, or 6kHz), and Band 4 (10kHz, 12.5kHz, or 15kHz). Once a frequency is selected, you can adjust its level from -12dB to +12dB in 1dB increments. The Q for each band can be adjusted independently: Band 1 (1, 2, or 3), Band 2 (1, 1.5, or 2), Band 3 (1, 2, or 3), and Band 4 (fixed bandwidth). In addition to the user-adjustable EQ (Users 1 or Users 2), tone presets are stored into memory, allowing you to recall the best setting for different types of music. You may choose from the following tone presets: Rock, Pops, Jazz & Blues, Electrical, Hip Hop & Rap, Easy Listen, Country, Classical, News, or Flat.
  • 3-Position 12dB/Octave Crossover: An 80Hz/120Hz/160Hz low-pass filter is available for the subwoofer outputs, and an 80Hz/120Hz/160Hz high-pass filter is available for the front right, front left, rear right and rear left preamp outputs. Either, or both, filters may be turned off.
  • Subwoofer Level Control: The level of the subwoofer preamp outputs can be adjusted to balance the output of your subwoofer with that of your other speakers.
  • Subwoofer Phase Selector: The phase of the subwoofer outputs may be set to normal (0 degrees) or reverse (180 degrees); this function allows you to minimize phase cancellation of bass frequencies, for stronger bass response.

MX (MediaXpander): The CDA-9830 features the MediaXpander function, which is offered on Bass Engine Pro, Bass Engine Plus, and some Bass Engine models. The MediaXpander function makes vocals or instruments sound distinct by restoring sound quality typically lost during recording or transmission; this function helps restore audio information that becomes obscured when audio is compressed. The MX function can be applied to all sources, except AM radio. There are three expansion modes for each internal source (CD, FM, MP3/WMA/XM), and each source can have its own setting. There are only one or two expansion modes available for external sources.

MP3/WMA Playback: This unit can play CD-ROM, CD-R, and CD-RW discs containing MP3/WMA files recorded using the ISO 9660 Level 1 or Level 2 formats. MP3 files with constant and variable bit rates from 8 kbps to 320 kbps and WMA files with constant and variable bit rates from 48 kbps to 192 kbps are supported. Discs recorded using Joliet or other ISSO 9660 compliant formats can be played, but file and folder names will not be displayed correctly. CD-ROM XA, Mixed Mode CD, Enhanced CD (CD-Extra) and multi-session recordings are supported, but recordings made using Track At Once or packet writing cannot be correctly played back. Discs containing both standard CD audio and MP3/WMA data can be played; the unit may be set to play only the CD audio tracks or both types of tracks. ID3 tag v1 and v2 are supported; track title, artist name and album name ID3 tag data can be displayed.

Disc and Station Titling: Titles of up to 8 characters in length may be entered for up to 24 radio stations and 18 CDs.

Satellite Radio Ready: There are several options for connecting an optional XM or Sirius Satellite Radio receiver to the CDA-9851. To receive XM Satellite Radio, you can connect the optional Terk XMD1000 Universal tuner (209XMD1000) and the Terk XM Direct Smart Digital Adapter for Alpine (209XMDALP1). To receive Sirius Satellite Radio, you can connect the optional Sirius tuner for Alpine (item # 607SIRALP1) directly to the head unit. A portable satellite radio receiver, such as the Delphi SkyFi or Sirius Sportster, can be connected to the head unit via an auxiliary input adapter. A compatible antenna and a subscription are also required to receive satellite radio programming from Sirius or XM.

Auxiliary Input Ready: With the addition of the optional KCA-121B Ai-NET/RCA interface cable, the KCA-801B auxiliary input adapter, or the KCA-410C Versatile-Link Terminal, the audio from an auxiliary source can be played through this unit. When the KCA-121B interface cable is used, a CD changer cannot be connected to the head unit; the KCA-801B auxiliary input adapter allows you to connect an auxiliary source and an Ai-NET changer to the head unit. The KCA-410C Versatile-Link Terminal allows you to feed audio from up to two auxiliary sources and two Ai-NET CD changers to the head unit.

MobileHub Link: Using the MobileHub Link, you can connect an optional Junction Box and a Nokia 6310i tri-band GSM cellular phone, allowing you to control the incoming and outgoing calls from the head unit. 

Power Off: When an external amplifier is connected and the built-in amplifier is not used, removing power from the built-in amplifier will improve the sound quality.

Changer Controls

Compatibility: This unit is compatible with 6- and 12-disc Alpine Ai-NET CD changers; also, this unit can control Alpine Ai-NET CD/MP3 changers and DVD changers. Alpine M-Bus CD changers cannot be controlled by this unit. 

Multiple Changer Control: With the addition of an optional adapter, more than one CD changer can be controlled. One KCA-400C adapter will allow you to connect up to 4 CD changers, and two KCA-400C adapters will allow you to connect up to a total of 6 CD changers. The KCA-410C Versatile-Link Terminal can be used to connect up to two CD changers and two auxiliary audio sources.

Text Display: When connected to a text capable changer, this unit can display text data from CD Text encoded CDs and MP3 CDs.

Disc Titling: When connected to a CD changer with disc title memory, CD titles may be entered and displayed for discs played in the changer. The title length and title capacity varies depending on the model of CD changer used; titles cannot be input for MP3 discs.

Clock Display Note

Clock Operation: This unit allows you to choose "keyed" or "unit on" clock operation. When the clock has been given display priority and the unit is turned off, the clock will be displayed whenever the ignition key is in the "on" or "accessory" position. If the clock is not given display priority, the clock is not displayed when the unit is off.
