Sound Quality. Ipod Ready. Sat Ready. EQ. Mp3. Display.

Cd skips on bumps. And u must have knowledge on how to adjust crossovers.

Best deck ive ever owned. seriously the eq is bad ass. i only have one issue with this deck and many people have pointed it out. the cd skips but that can easily be fixed by just adding a ipod adapter. I also love the fact that u can tune your radio online to the exact specs of your speakers, subs, and car. I love this radio. I highly recommend it if your familiar with crossovers and alpine eq's.

Great display, wide choice of colors, tilting face.

WAY too many miniscule fine-tunings but virtually ZERO basic ones. No loudness (Pioneer has 3 levels) no basic bass/treble/midrange controls, poor clarity, sounds like a warped disc at times.

This is quite possibly the most disappointing purchase of my life. Alpine was supposed to be "the best" so I built an entirely new system for my corvette around it. Highest power Punch amps, Power series speakers, component sets up front. I have never messed around with a device longer than this head unit, simply trying to get a decent sound. Way too many x-over controls, eq is a joke and adjusts virtually nothing, no loudness or basic bass & treble control. I took everything but the head unit out, and hooked it up in my winter beater to an $80 Pioneer HU. Guess what? The best sounding system I've ever heard! Re-wired entire vette, made sure everything was correct, everything was. Hooked it all back up...same crap sound. Horrible mid-high separation, bass is overblown...I have to readjust the amp gains for each cd I put in. This is the legendary Alpine sound???Terrible. I have spent countless hours trying to rectify the sound...to no avail. It has now been torn out and I am awaiting the arrival of my new Pioneer Premier deck. What a waste of potential and money.

Why did I ever abandon Pioneer. Lesson learned.

none at all,

Alpine is thier own weakness. I have repeatedly called alpine trying to talk to a manager, to see if they will stand behind thier product, I get put on hold, they take my number, and do not return my calls. $95 to repair a unit that if lucky may work for 6 months.

this H.U. is junk. xmas '04 recieved unit as gift. June '05 first unit defective, cd player skipped, cd player would stick, same time every cd. alpine sent refurb. Jan '06 another six months later. refurb. unit will not take a cd. error. send back to alpine again. I will never purchase another Alpine product again

looks, reliable, sound, xover, time correction, peq, programable presets, tilt, remote, knob, 3 gold 4 volt preouts, night display, 512 colors, easy to use, no b.s. instructions

display is sometimes hard to see during the day

this deck kicks a$$. tones of features. looks killer at night. what deck has 1st, 2nd, 3rd and 4th order xovers, 6 channel time correction, and a 5 band peq for $450 and sounds and looks this good....none!!! i demoed a similar deck but it was sill $550, it was Eclipses #2 deck, i think the 5444 or somethin like that Eclipse decks are nice but the highs sounded horrible.. cymbals sounded cheap and not airy at all.. also the deck is no where near as flexible when it comes to tweaking the sound.. i must say, the E sounds killer when using the DSP feature tho, too bad the 9833 doesnt have DSP some of these other reviews are fools, dont even know what a peq is or dont even know how to use it like ive said many times... still havent found a deck id rather have, any price

the guy down here is really crazy, how he can tell that sony (car audio junk) is better than alpine??, audiophile´s friends he is blasphemy our sound god!!!!. man this head unit has incredible sound if you have a good amp with a good component speaker. parametric eq is the best, fine tuning for all frequency, time correction really help to minimize distortion, you can really fell the difference, 4V, and a lot of specs that can make a big big difference in sound quality. that guy is really crazy when sony has win an audiophile contest???? NEVER MY MANNNN. in all of the car audio contest i went ,always i saw alpine or eclipse head units in the most of the cars

The color adjustment on the display is nice. Media expander is good and enhances MP3 playback nicely. The faceplate tilt is REALLY nice. The display has some decent flexibility.

Bad sound control. period. Bass Engine is a joke. Extremely high trebble default. I can deal with a bad display and nutty controls as long as the sound is awesome, and sound is what it's all about. I had hoped that this units would deliver especially for the price, but sadly, that isn't the case. I wouldn't recommend this unit at all. I'm not sure if I'd recommend Alpine in general since I don't have more exposure to other units, so I'll leave that recommendation open.

Of all the units I have had in my car, this unit has the worst sound curve control and output. I know there are a lot of alpine lovers out there, and I don't know what else they've been exposed to for comparison, however, my experience with this alpine unit has been disappointing to say the least. My main speakers are the same since my first installation and can drive some serious bass and overall sound. This system simply doesn't cut it for bass even after disabling (as best as I can figure) the "active" crossovers. The result was only barely noticeable bass increasy. The default sound curve on this unit seems to be no bass and screeching trebble. After adjusting the high frequencies to minimum, the trebble is still WAY too high. The frequency centers only adjust that specific frequency plus or minus the "Q" level (which at maximum spread doesn't help much). The best sound curve adjustment is a single spline curve along the specified frequency points. This head unit does not do that. I tried compensating with adjusting my amps, and that didn't help enough. Imagine Winamp sounding better. I thought my Kenwood had some complex menus and controls, but the alpine is even more complex. Having complicated controls doesn't bother me as long as the results are good, and they are simply not happening here. Comparing with my other systems, I have to say, unforunately, that this is not a good system at all. It retails for $500+/-, and I'd say it's only worth about $150-200 for such a system. Perhaps Alpine has gone the way of Sony, but I have not had any prior Alpine system to compare, and it's a shame if this performance is the way they have always been.

clear sound, very nice looking, pro head unit

difficult to use at expert level, weak woofer control

its a really nice head unit, dont have a screen savers as panasonics at same price but have a lot of features which w/o manuals u wont find, im a little dissapointed about woofer controls, you can add only 10db at 40hz thats all, in some songs ( most mp3) there is not to good base

Great clarity, and sound. Keeps the sound tight. Great remote control. looks good in my truck. Great MP3 feature--easy to use, just put different artists in different folders and you almost NEVER have to change the CD, once you burn all your favorite songs on the CD.

None so far. I AM the weakness---I am so used to simple units. This is a thinking man's unit.

I relpaced the Dodge factory cd player. Needless to say, this head unit rocks! It is complex, BUT, if i had a headunit I could figure out without reading the manual, I would be bored in a week. This is NOT a boring unit. The more I tweak it, the better it gets, and the options are just plentiful.
