Our take on the Pioneer Stage 4 DEX-P99RS

The DEX-P99RS houses its electronics in a copper-plated chassis that eliminates RF and magnetic signals that can introduce unwanted noise into even the finest audio components. Pioneer designed the circuit paths to be as short and symmetrical as possible, while all internal components are carefully arranged and shielded. All of these steps reduce interference that can diminish sound quality.

Pioneer's Stage 4 flagship receiver

Why run with the herd when you can be leader of the pack? Pioneer's Stage 4 DEX-P99RS isn't just another car CD receiver — it's an audiophile platform of the highest quality, built from the ground up for audio enthusiasts who won't settle for second best. There's no internal amp in the DEX-P99RS — connect the pristine output to external amplifiers when you build your system.


The DEX-P99R is at the heart of Pioneer's Stage 4 lineup

Custom components and uncompromising construction

A copper clad chassis

The DEX-P99RS houses its electronics in a copper-plated chassis that eliminates RF and magnetic signals that can introduce unwanted noise into even the finest audio components. Pioneer designed the circuit paths to be as short and symmetrical as possible, while all internal components are carefully arranged and shielded. All of these steps reduce interference that can diminish sound quality.

Top-of-the-line components

The engineers at Pioneer realize that standard "off-the-shelf" parts just won't cut it when you're shooting for reference standard performance. They use custom-designed audiophile-grade capacitors built specifically for the DEX-P99RS, ensuring the highest quality parts and cleanest performance. The receiver's preamp section, which uses the same Linear Technology technology found in high-end home audio systems, receives ample supplies of current from the receiver's dual power supplies, a rarity in car stereo construction.

Cutting-edge digital technology

If digital data isn't translated into the analog domain accurately, your sound will be subtly out of phase, resulting in a loss of precision and the addition of distortion. The DEX-P99RS employs Sound Master Clock Circuitry that guarantees ultra-precise digital-to-analog conversion.

The receiver also uses four digital-to-analog converters (DACs), one each for the preamp outputs, to convert your digital media with the highest possible signal-to-noise ratio and outstanding dynamic range. The 32-bit binary floating-bit digital signal processor provides high-speed sound processing for greater realism than the processing found in other car receivers.

Outstanding tools for sound adjustment

Rear panel connections

The 31-band equalizer offers independent control over the right and left channels for unparalleled shaping of the acoustic output. You can even set up five different custom memories to handle different types of music or listening situations.

The Auto EQ's supplied microphone samples the sound in your car, then tunes the 31 separate frequency bands to your interior, while balancing the output of all of your speakers independently. It also adjusts the time alignment of your system automatically to compensate for the differences in speaker distance from the driver — all the sound will reach your ears in perfect synchronization.

Want to keep your car's steering wheel audio controls?
In most vehicles, you can use an adapter (not included) to connect your vehicle's steering wheel controls to this Pioneer stereo. Connect a few wires, then program the adapter for your particular car and the receiver, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.

iPod note: If you're going to use your iPod with this receiver, be sure to check Product Research for specific iPod model compatibility with this receiver or its optional iPod adapter.

    Pioneer Stage 4 DEX-P99RS

    Guest from Palmdale, CA on 10/4/2018

    It's a pretty good head unit but way overpriced and over rated ! That's why I give it 3 stars



    Audiophile Sound Quality. Uncompromised.

    Dominique from Melbourne, Australia on 3/26/2018

    I am the proud owner of the Pioneer DEX-P99RS and I have loved every moment of ownership! This reference grade instrument really gives you insight to your music and really pushes the boundaries of what you can achieve sonically. "SOUND" The way the DEX-P99RS accurately produces even the subtle details of music is truly special, I especially adore the way it crafts such an effortless sense of realism when it comes to all the minute details such as superior dynamics, timing, rhythm & pace as to paint such a vivid soundstage with true scale. In regards to the DEX-P99RS tonality, it has an incredible sound signature that is worthy of "Reference Status" and delivers that admirable "Analog Warmth" with such a high degree of control & breathtaking realism. The sound reproduction of the DEX-P99RS on all facets is truly flawless. "CONTROL"The DEX-P99RS possesses all the control you require to set up even the most complex of systems. Aside from the impressive 31 band EQ (separate L/R), it also gives full flexibility in regards to X-overs, slopes, phase and level adjustment. It also has full time alignment with small increment adjustability to fine tune to perfection. I use the DEX-P99RS in my competition vehicle along with 4 X Pioneer PRS-D800 amplifiers which drives the fully active Focal Utopia Be 3 way front stage kit. The feedback I receive from demonstrations and the judges is always positive and is a true testament to the extraordinary capabilitie

    Pros: Reference Grade Sound Quality. Flexibility in Configuration. No Compromise Design.

    Cons: For what this was designed to for.. None!

    Best car stereo ever owned

    Pros: Quality, very classy looking, very clean sound

    Cons: Price

    Buy this HU if you have a complicated setup

    Randy from Tolleson, AZ on 11/1/2017

    2015 Subaru WRX STI
    Crutchfield Customer Review (What's this?)

    I replaced a Pioneer 4100 AVH NEX model (didn't sound good and it's features are glitchy) with this HU. Difference in sound quality and adjustability justifies the price. 31 bands of EQ adjustment goes a long way to taming potentially harsh sounding, high resolution speakers. You will need something of this caliber to extract the most out of expensive gear. My system finally up to it's full potential.

    Pros: Will tame the harshest system, unrivaled SQ.

    Cons: Expensive, you will forego features like Carplay (who cares?)

    Just grab the keys and let the concert begin!

    Anthony from San Diego, CA on 2/10/2017

    I have this installed in a 2013 Hyundai with a dual battery system install. My front stage consist of a Focal Audio Elite 165KX3 component system. My front stage is bi-amplified and a drive anywhere is an excellent excuse to get lost within sonic nirvana. If you like listening to CD's this is an excellent piece of sonic gear. I added a Pioneer Premier 6 disc changer for swapping convenience.

    Pros: Phenomenal build quality, exquisite and sexy. This has an insane learning curve and is a dream to own. I get this RTA'd on the dailies!

    Cons: Egg shaped remote could have been designed a little better, my hands are small.

    Crutchfield Customer Review (What's this?)

    This has got to be the cleanest sounding head unit I've ever owned as soon as I hooked it up the bass hit harder and lower and the highs became sharp clear and loud it took me about a day to figure out how to tune it in and I still have to refer to the manual for some of the other settings.. If you want the best pre amp signal get this unit

    Pros: The network out puts with active hpf and lpf and the equalizer

    Cons: Wish this unit was touch screen and had Bluetooth and also it would be nice to be able to change the crossover type

    Crutchfield Customer Review (What's this?)

    Phenomenal car stereo for the true fan of music! It is everything I could have asked for and so much more capability than most of the receivers in its catagory. I am very satisfied with this product!

    Pros: Great sound and build quality with infinite sound shaping possibilities.

    Cons: You must read the manual (lots of homework) in order to correctly operate the stereo.

    Great SQ head unit

    cmusic from Staffordsville, KY on 5/17/2016

    2006 Lexus IS250
    Crutchfield Customer Review (What's this?)

    The DEH-P99RS is an excellent top quality CD Tuner with an added 4 way digital crossover with time alignment and dual 31 band equalizers. For those that know how to use its processing features, it is a great unit. If you are not an experienced tuner, either let someone that knows how to tune adjust this deck or buy something else.

    Pros: Everything an experienced tuner and sound quality expert needs in one unit.

    Cons: The two knobs on the front are somewhat flimsy as compared to the rest of the deck's solid build quality.

    Great head unit

    Love this product. Best I have ever owned!!! Nothing out there compares to it...

    Pros: Love all about it!! Totally Awesome....

    Cons: None..

    It's so good I bought 2 of them.

    ForrestD from North Carolina on 8/4/2015

    Crutchfield Customer Review (What's this?)

    I bought my first DEX-P99RS used from a giant online auction site last year. It was to spend it's life in a garage-queen SQ car that I occasionally show. I run a 2-way active Focal KRX2 set up-front in that car with Rockford Fosgate T1692 6x9's in the rear. I have 2 x JL Audio 13w6v2's for subs. I have Mosconi AS200.4 amps for the fronts / subs and a Mosconi Gladen One 240.2 for the rears. The DEX-P99RS is the primary source unit / DSP. I have a second head unit (Pioneer AVH-X7500BT) that I use for bluetooth/backup camera/etc. that passes through the DEX-P99RS via an Aux. input. I was so impressed with the DEX-P99RS in that car that I bought another DEX-P99RS from Crutchfield to install in my daily driver. It is the same system completely except that my daily does not have any rear speakers or the Mosconi Gladen One 240.2. After tuning with the DEX-P99RS (both manual tuning and AutoEQ/AutoTA), I am just enamored with the DEX-P99RS. It has a near-full tuning suite, and it is completely available to the tuner without need of any external devices (like laptops, pc's, tablets, etc). Everything you need to tune (minus your tuning music or tones) is available via the handheld remote control and display on the unit. The only thing I can think of that would make it better (and this really would only take it from 100% to 105% awesome to me) would be adding some ability to change crossover filter type (Butterworth, Chebyshev, etc.). The DEX-P99RS is just awesome.

    Pros: Left & Right 31 band EQ's. Full Time Alignment (all 8 channels). Good AutoEQ results. Good AutoTA function. Great CD mechanism. Great iPod interface. Highly customizeable (display, colors, sound, etc). Very classy design.

    Cons: It's more expensive than a decent double din + external DSP. You can get a similar experience in AutoEQ and AutoTA with one of Pioneer's lower line double din units (AVH-X1700 - AVH-X5700BHS units). I had an AVH-X5700BHS prior.

    Spend the money!

    1985 Cadillac Eldorado
    Crutchfield Customer Review (What's this?)

    I've been building systems since 1988 and this deck is the best I've ever owned! I started out looking for an 8 channel crossover to go with a new head unit when I came across this one. When I looked at the price of the deck I wanted and the crossover separately, it made more since to spend about $100 more to get both pieces in one unit. Best decision I could have ever made! After tweaking the EQ for about a week, I found myself in audio heaven. I will be in Nirvana when I swap out the JL Audio speakers for Focal components. EVERYONE who sits in my car tells me that I have the cleanest sounding stereo they've ever heard. Having control over directing the right frequencies to the correct speakers in the same unit is priceless!

    Pros: 31 channels to tweak the way different genres of music sound. Audio setting that shapes sound for just the people in the front seats. Removable head unit for security.

    Cons: Doesn't have Bluetooth. Learning curve for tweaking.

    best deck ever

    lew from New York on 4/1/2015

    Crutchfield Customer Review (What's this?)

    this deck is by far the best deck i ever used . it takes a while to figure out the set up areas but customer service is a big help . this replaced my eclipse 8053 and it made my old deck seem lke it was a factory head unit . I didnt want to spend this much money but it was worth it , im so happy I took the plung . Had to buy the extra remote from Crutchfield because the one that came with it is so darn small ,

    Pros: best deck ever , one crossovers were set the cds took on a new life even before setting the eq and time delay

    Cons: set up takes a learning curve and remote is hard to use if you have large hands . price

    A tad expensive but wort it!

    Pioneer Stage 4 Head Unit

    John from NJ on 3/18/2015

    Crutchfield Customer Review (What's this?)

    It's getting harder to find pre amp only head units these day. That's what brought me to the Pioneer. I was impressed with the build quality and the sound quality was top shelf. You get a ton of customizable settings. If you're concerned only with sound quality this might be the best deck on the market right now.

    Pros: Sound quality Solid construction Plenty of custom settings and flexibility

    Cons: It would be nice if the head unit had a digital input and balanced line outputs.

    The best since my old Sony CDX-C90 ES from 1999

    Shanes from NJ on 11/26/2014

    I thought the last 10 + years of of high end head units were pretty much a lost cause since everything has become tailored for iPod quality sound, which as we know isn't nearly as good as complacent disc. This prs 99 is an outstanding piece of engineering and for me to say that means a lot. This is the first time be been this excited about a head unit since the previous Sony CDX-C90 that had its quad Burr Brown 20 bit DAC's. I've installed this unit I my 2011 Honda Element and I'm looking to upgrade the speakers really soon to Focal components. This unit is top notch and will sure be another ledgend in car audio.

    Pros: Old school quality with faculty for modern day tech like iPhones and such.

    Cons: Would like it to be able to play high resolution audio such as FLAC or ALAC 24/192 kHz files burned to a dvd or play sacd discs.

    Pioneer DEX-P99RS

    Dale.M from Boise, ID. on 6/5/2014

    Crutchfield Customer Review (What's this?)

    I believe that this is a difficult unit to understand. I took over one year to appriecate the built in quality of this CD player. Oneday i thought I finally had it tuned in and not evan close. I didn't understand that adjustments with the engine off only produce 12.5 to 12.8 volts-14.6 volts when engine is on. the sounds produced are different. didn't realize that all cd's are not recorded the same. Bad recordings are bad-not a thing you can do-if you try and adjust for the bad sound you then take and destroy a good recording. You adjust once again and wonder if you will ever find the Utopia sound that you have paid for. I have the Utopia NO7 Active/Two Milbert Bam 235ab's and one Mosconi 200.4. I have them installed in a 78 ford pickup. Believe me when i say that I have been through heck with this system. One day I'm driving down the road and decide to take the tweets down to 1245 hrz, I had them at 3500-the sound opened up and the recording bloomed to a level never heard-but this was by accident. I have given-up on adjustments that are by the book and went with my ear. I'm an old man. Understand what it is you have and the system I have is truly Utopia. This CD player has enough adjustments that whatever your hearing is, it can provide for it. I was headed to the dump with this system-But I didn't give up. Sound proofing, wires, and anything else plays on the other-weakest point is the strongest. Dual batt.- 200 amp alternator and the list just goes on.

    Pros: It can provide the best sound out there. Or it can take and break your spirit.

    Cons: Patience, Time and money.

    Crutchfield Customer Review (What's this?)

    I have been waiting for this type of receiver for ever.The Last time I seen a preamp receiver was in the 80's was a Kenwood cassette receiver it was top of line, Now in the twenty teens we have once again simply the best sound, all I care about is the best sound possible period.

    Pros: The best sound Quality in a CD receiver. no bells and whistles, just pure SQ.

    Cons: none.

    Best stereo money can buy

    mario from albuquerque, nm on 4/18/2014

    2004 Acura 3.2TL
    Crutchfield Customer Review (What's this?)

    Expensive but well worth the money. Once I got my system tuned all I can say is... WOW I am impressed to say the least. There is definately a learning curve in getting in and out of menus but after a few days you'll be able to change your setting with ease. The stereo comes with the capabiity to auto tune itselft to your car but any serious audiophile will opt to set it up manually and for this I would recommend Room Eq RTA software as well as a calibrated mic. There is alot of info at DIYmobieaudio specically for this stereo so pleny of help is availble if you choose to tune your car manually. Also make sure you have decent drivers, amps, wiring and clean power or you will be wasting your money and time with this high end stereo. I currently have Focal KRX2 midrivers, hiquophen tweeters, jl audio12W6 sub and jl audio hd amps, with wiring including an alternator upgrade and sound deadening and this stereo sounds great

    Pros: Clean pure sound with the versatility to tune your stereo exactly how you want to.

    Cons: Price, but hey you're paying for the best in the market.

    If you are serious about QUALITY sound ............

    Audio Buff from Belleville, IL on 12/30/2013

    2002 Cadillac Escalade EXT
    Crutchfield Customer Review (What's this?)

    This is THE BEST car receiver I have EVER owned!! It is a tuner and 31 Band equalizer in ONE!! My speakers literally came to life when I installed this unit. Simplest install ever, but HIGHLY involved in setting up. The setup is definitely not a discouraging point though. Once you learned you don't forget it. I like how you can adjust the time alignment of each speaker and set the levels for each channel (i.e. LF~RF~LR~RR). This unit separates each speaker into Sub, Low, Mid, and High groups. You MUST have an amplifier in order to use this head unit!! I have had this head unit for a month now and after extensive hours of fine tuning the AUTO adjustments I am literally speechless on how GREAT my system sounds. I only changed the head unit (no amplifier tweaks or speaker upgrades or anything) and my speakers seem like they woke-up from their nap of boredom!! If you enjoy listening to music for sound quality then this is DEFINITELY the unit for you!!!

    Pros: Super easy installation; backup battery in case of power loss; beautiful display; classy and professional appearance; steering wheel remote control; auto tuning feature; the list goes on and on!!

    Cons: Setup is not the easiest, but it can be accomplished with reading the manual and doing research on what sounds the frequency bands produce

    Great Quality

    Crutchfield customer from Houston TX on 11/5/2013

    2009 Dodge Challenger
    Crutchfield Customer Review (What's this?)

    Out of the box performance. I installed this unit in a 2009 Challenger SRT8 using a McIntosh MC440 6ch amp. Hooked up to the stock speakers with no tuning and still blew me away with sound quality. I currently have a Clarion DRZ9255, Addzest HX-D1, Clarion DRX-9255, Pioneer deh-p880prs, Clarion HX-D10, McIntosh MX-406, and McIntosh Mx5000. All models listed are excellent SQ. pieces and all were hooked up to McIntosh amps when tested. The biggest problem with testing different CD players is using the same amps and speakers when testing so you have a more accurate comparison. I thought I had the best until I heard the Pioneer.

    Pros: SQ. Very clean unit looks amazing

    Cons: Tuning is a bit complicated. It would be nice if Bluetooth was already installed instead of the $200 add on.

    Hard to beat

    Jojo from Fresno,Ca on 10/30/2013

    1992 Nissan Pathfinder
    Crutchfield Customer Review (What's this?)

    There is really not much out there that comes close to this head unit. I am someone that is a bit leery about audio manufacturers that tout features without saying much about the efforts and technology used to to make their components sound great. Pioneer has built a deck that is packed with SQ focused technology - 4 24 bit DAC's, custom made capacitors, copper shielding, cd mechanism that is isolated from external vibrations, etc. they have produced a deck that demonstrates a complete focus on sound quality, and built into it features that set it apart from the competition such as ipod connectivity, hd tuner ready, built in crossovers and 31 band eq, time alignment, 2 aux inputs plus a USB input, giving you three different options for expansion. All of this in a single din unit. I was originally in the market for a nakamichi cd700ii. What I found is that Nakamichi's legendary flagship CD player has reliability issues and hard to find support. This Pioneer, with its conveniences and features as well as a Focus on sound quality made it hard to beat. No external crossovers to install. Everything can be controlled and tweaked from the driver's seat. It's an amazing deck, both in features and sound quality. I hated picking Pioneer over Nakamichi, but I am very happy with this deck and am convinced it is the better HU - probably one of the best out there.

    Pros: Sound quality and feature set.

    Cons: There's a bit of a learning curve figuring out the controls. Nothing too difficult, and once you figure it out, it gets easy. At first it can seem a bit too involved and non-intuitive. Ultimately it's not bad, you just have to get past the initial getting acquainted stage.


    Troy from Columbia,mo on 10/7/2013

    2010 Toyota Tacoma
    Crutchfield Customer Review (What's this?)

    I got this installed a few weeks ago. I waited to write this because it takes a little while to figure out this unit. I have it in a 2010 Tacoma it still has the factory door speakers but I installes a JL XD700/5 amp and a sealed prefab box with a alpine type R 10. I will warn you that the set up can be very difficult but the great thing is it has an auto tune feature that works extremely well. I have dealt with auto tuning system before like the alpine ones but this Pioneer auto tune is almost spot on!!! The ipod sound is much better than expected. The sound all around is truly amazing and that is with the factory front speakers cant wait to install son really nice components with some soft dome tweeters!!! It is a very pricey unit but I am very happy with the results!!!

    Pros: DAC, tuning ability, clean sound

    Cons: price and difficult to set up

    beyond belief

    zech912 from Phoenix, AZ on 6/22/2013

    I have had my installs done at the very best shop, with high end Focal and JL components, amps, subs. Because the shop is used to high end (but they do not currently carry Pioneer), they have always been: "ho-hum, it's ready, here are your keys." But when I had this deck installed (again, not even purchased there), they came out to the waiting room and said with a bit of awe: "This is amazing, you have got to come back and hear this." The installers were back there themselves admiring the beautiful audio. If I close my eyes, I can easily imagine I am in the studio itself. Well done Pioneer. As far as the complexity, I would never take on adjusting the crossovers, TA, things like that (but easy for the brilliant installer and those who understand how to do so), but the EQ and other settings are all well within the novice's ability, and fun to set.

    Pros: beautiful sound, beautiful understated appearance. words inadequate.

    Cons: The color of the dial lighting is adjustable, but not the center text/ sound level display. The sound level display is something I have missed for years, it is absolutely awesome that this has it, and the white is great, so I am going to extreme effort to find a con, but here it is: It would be great if the sound level display was also adjustable.

    Best Radio out there!

    Mmac from Little Rock, Arkansas on 5/1/2013

    Crutchfield Customer Review (What's this?)

    I have two of these decks and they are awesome! I have never had such a deck that puts out the quality of sound the Dex-P99rs does. great sound, great enhancement to my ipod and sounds even better with a CD.

    Pros: Competition radio for sure!

    Cons: Took me a while to fully understand the full potential this deck has to offer. But other than the patients of studing the manuel it's worth every penny!

    Every Note is perfect

    Ralph from NJ on 4/8/2013

    Fantastic ! I installed the ultimate STAGE 4 system, for about $7,000+ and it sounds like it was worth every penny. I can hear music the way it was meant to be heard , the way engineers recorded it. I combined the Head unit with Pioneer stage 4 amps & speakers and they sound amazing.

    Pros: TA - time alignment . Auto Equalization . Control over the configuration of all the crossovers & slopes from the head unit is great Control of 4 seperate preamp outs is great for fine tuning the system.

    Cons: Cost is very high but worht it.

    Best ever

    Best SQ deck ever! But this deck is not for beginners. Very advanced tuning knowledge is required or your wasting your money. Wish they made this deck in a dbl din touch screen version. Would make tuning much easier, Please pioneer read this.

    Pros: Beautiful sound quality. Great simple classy look.

    Crutchfield Customer Review (What's this?)

    Pure joy...If you are serious about music, you NEED to get this deck. Upgraded from the DEX-880PRS, there is a HUGE difference. SQ from this deck is simply amazing. I don't want to leave the car, I sometimes will just sit in the car after getting home just to bask in the amazing sound this deck delivers. I was really hesitant on the upgrade, kept asking myself, "could there be that much of a difference?" "Is it worth the money?" An astounding YES, YES, YES!!! This deck even makes your iPod sound good, huh...

    Pros: Total system control! Tweak-ability. SQ

    Cons: Price

    To be the owner of one of these Head Units, i am extremely proud, i cannot think of another Product in recent time that i have spent so much of my time with, my commute to work , even in extreme traffic jam on I-95 in Miami is heavenly, prior to purchasing this unit, i decided to invest in high quality Speaker Cable and Interconnects, this Unit is currently connected to (2) 5 Meter length of Audioquest Columbia Interconnects and Audioquest Type 4 Speaker Cables, my aim was to have maximum transfer of the Signals to the Amps. i would recommend this Unit to any one who is looking for an heavenly time in their vehicle

    Pros: Sound quality, Built Quality, Tuning Capabilities, Remote control Etc.

    Cons: Annoying Error 19 and Error 16 Messages, High price tag

    There can be only one

    Crutchfield Customer Review (What's this?)

    If you value sound or wounder what is missing in your current SQ system this is the HU for you. The price is ridiculously low for the capabilities this product brings to the table. Even if you choose to never use the Auto-tune, EQ, TA, or crossover point/ slope the HU is a great CD player and easily the the best sounding radio I have EVER heard in a car. There can be only one best available HU and this is it

    Pros: attractive understated appearance, best sounding HU for sale in USA, tremendous user control, auto EQ actually works well, silent operation, the radio sounds excellent with the best RECEPTION I have gotten in over 2 decades! The biggest Pro is the Crutchfield service

    Cons: the menus are complicated so it is not that easy to use all those audio features even with the users manual, knobs are small and slick

    one of a kind

    What an awesome piece. Its fairly simplistic, no frills appearance is merely a front for one of the most versatile pieces of equipment Ive ever seen. The complete adjustability is mind blowing. Theres nothing else you will ever need. The sound quality is top notch to say the least. As someone else said... If your serious about your sounds, you need this piece.

    Pros: everything inside the box


    Review Revisited

    MBluAgain from Fort Lauderdale on 1/5/2012

    I needed to update the previous review. I called support about the issue with the blanking display and I was immediately sent a new unit as an advance replacement for the wonky unit. If you are considering a purchase of this, the King Kong of all head units, you would be silly to buy it elsewhere. Nice Job.



    Sound and Features-Great, Build Quality-?

    MBlu from Fort Lauderdale on 12/29/2011

    Crutchfield Customer Review (What's this?)

    I purchased this unit in March 2011. All the reviews and the hype are true. This thing is the Bee's Knees. Complaints about the remote are silly and in my case the remote is the only way to control the head unit. That is because when I touch the face-plate controls on the right side of the unit, it blacks out and locks up. I can't control anything including turning it off, not with the remote or the wheel controls. I have to stop the car, turn the car off and restart the system. It started as an occasional glitch and is now an every touch occurrence. I thought that there might be some sort of coverage since it was a signature product, but no information remains about the signature program, so I don't know.

    Pros: Sound and Versatility

    Cons: Quality

    Crutchfield Customer Review (What's this?)

    The HiFi option to my MY98 Porsche 911(993) needed an upgrade to present day car audio HiFi offerings. When researching the best of the best the DEX P99RS head unit came highly recomended... by even its competitors no less fancy that. The elegant asthetic of the P99RS supports the 911s interior and the tier one audio presentation matches the hi performance of the car itself. A couple of PRS- A900 amplifiers rounds out the new HiFi system.

    Pros: Audio performance, understated asthetic, DSP filtering, 24/96 DAC, display color choices, 4 channel output, did I mention audio performance. I wanted the best of the best... and thank Gawd the best is understated asthetically... Fits the 993 Porsche dash like it was OEM.

    Cons: Not enough understanding of the P99RS functionality at this time. Not one to duck bit a product.

    Simply amazing

    Crutchfield Customer Review (What's this?)

    I ordered this unit for my Dodge Ram 3500 and even though I thought I had a good sounding system already, this completely represents what music is all about. Music has a complete different sound, you will hear tones from instruments you've been missing. If you are looking to hear music the way it is supposed to be heard then you are looking at the right unit. I have been an audio junkie for greater of 17 years and have never heard anything like this. Ever. Simply Amazing.



    Excellent. If you're serious, you need this.

    TD76 from NJ on 1/6/2011

    Crutchfield Customer Review (What's this?)

    Simply put, this is an absolutely excellent receiver. If you're serious in to sound quality and car audio, this is the receiver for you. Combine excellent tuning/processing with an audiophile quality unit and you have a winner. I was never a Pioneer guy before buying this unit, but when this hit the United States, I absolutely could not resist. I bought it the first day that Crutchfield got them in stock a while back. Build quality, sound quality, etc are all top notch. Sound stage is wide and very detailed. Some other great bonuses of this unit are the fact that it has USB input and works great with an external hard drive (lossless files via .WAV are supported as well), color of button illumination can be changed (which is important for me to keep a stealth integration), OEM steering wheel support, and more. After much tuning, its sounds absolutely fantastic. The time-alignment and very adjustable crossover network are worth it alone. Dual 31band EQ just adds to the awesomeness. Only thing I was not crazy about was the Auto TA/EQ/X-OVER results. Doing it by self yielded MUCH better results.



    world class

    instalher from chilliwack b.c. on 11/23/2010

    wonderful deck, easy to use and looks great in most dashes... the sound quality of this deck beats my old denford hands down. also feature for feature nothing comes close for the price.. i have a top 3 iasca car in the world and use this deck, which is why i place so high.. the remote is very intuitive and easy to use and can work from almost anyplace in the car.. my one grip is at night you cant see the buttons on the remote.. they should lite up and the carry case is cheap junk.. for the money i would expect only the best. if you can live with these tiny problems and have some money buy this deck!!

    Fantastic Receiver. The Autotuning capabilities (in regard to positioning & equalizing) can make anyone's stereo sound like they know what they're doing. If you have the $ (it's expensive!), this should definitely be high on your list. If you get a chance to listen to one -- go for it! You'll be glad you did.



    Pioneer does it again

    JG from ND, USA on 10/27/2010

    I have used many Pioneer decks in several different vehicles and have yet to be disappointed. This deck in particular is nearly perfect in most ways. I would recommend it to anyone with moderate or greater knowledge of the car audio world. Tuning is pretty straightforward and sound is excellent once tuning is completed. If you are a beginner, you may want to do your homework before purchasing, otherwise, for all you audiophiles out there, this deck is where its at. Kudos Pioneer and Crutchfield for great products and service.

    I have been a loyal Pioneer buyer for over 15 years and have yet to be dissapointed, from my first $500 car- to now customs that I have been fortunate enough to be able to build for people, I have always been able to depend on Pioneer electronics, this dex-p99rs is an awesome reciever, skillfully designed, with symetrical modest and almost undercover styling, plus amazing audiophile sound and adjustability. I would have paid twice retail just to say I installed one of these(dont get any crazy ideas Crutchfield ) Great job Pioneer! I am forever jealous of your mad skillz...

    Reference Series Construction: The Pioneer Reference-Series DEX-P99RS features high-quality construction for better sound reproduction:

    • Copper-Plated Chassis: The Reference-Series DEX-P99RS features a copper-plated chassis to eliminate magnetic induction noise.
    • L/R Symmetric PCB: The Reference-Series DEX-P99RS's entire circuit board is painstakingly designed for utmost sound quality. Circuit trace path lengths are equalized and kept as short as possible, and components are carefully laid out and shielded to prevent RF noise or interference.
    • Custom-Made Capacitors: The Pioneer Reference-Series DEX-P99RS utilizes custom-made audiophile grade capacitors and other components to ensure the highest quality.

    Reference Series Sound: The Pioneer Reference-Series DEX-P99RS provides the purest, most realistic sound in your car by using high-quality circuitry, high-performance DACs, and high-precision digital-signal processing (DSP).

    • Sound Master Clock Circuitry: The latest integrated circuits require superior clock signal quality to handle digital data accurately without distortion at ever-higher speeds. The Sound Master Clock Circuitry generates clock waveforms to read and process digital signals with ultra-precision, and eliminate jitter noise in transmission. The result is faithful playback of the original source.
    • High-Slew Rate OP Amp: The DEX-P99RS features Linear Technology Corporation's high-slew rate OP amplifier used in high-end home audio for its precise gain and sound linearity characteristics.
    • L/R Independent High-Volt Volume Circuit: The DEX-P99RS features a custom-made electric volume driven by a dual-sided power supply (rarely found in a head unit), which provides overwhelming dynamic range and high S/N (Signal-to-Noise) ratio.
    • 24-Bit AKM DACs: The Pioneer Reference-Series DEX-P99RS uses four 24-bit AKM DACs (one for each preamp output: high, mid, low, and sub). These four 24-bit AKM DACs offer a 115dB S/N ratio with a high-durability to jitter, and superior dynamic range and quietness.
    • 32-Bit Binary Floating-Point DSP: The DEX-P99RS incorporates 32-Bit Binary Floating-Point DSP for high-precision and high-speed sound processing. The unique use of 32-bit "floating point" DSP offers significantly higher accuracy, especially at high frequencies and low signal levels.

    4 Pair of 5.0-Volt Preamp Outputs With DSP Control: The Pioneer DEX-P99RS features four pairs of 5.0-volt preamp outputs (High, Mid, Low, Sub), along with a 4-way network DSP. This allows you to create a 4-way multi-amp, multi-speaker system with separate speakers for reproduction of high, middle, low, and ultra-low frequencies (bands), each driven by a dedicated amplifier (sold separately). The 4-Way Network DSP lets you divide the audio signal into different frequency bands, and then reproduce each of them through the units corresponding preamp outputs. You can then make precise adjustments to the reproduced frequency band (with a low-pass filter and high-pass filter), level, phase, and other parameters to match the characteristics of each pair of preamp outputs.

    • Frequency Range: You can adjust the HPF (high-pass filter) and LPF (low-pass filter) cut-of frequency to set the reproduced frequency range for each pair of preamp outputs. The HPF cuts frequencies (low) below the set frequency, letting only high frequencies to pass through. The LPF cuts frequencies (high) above the set frequency, letting only low frequencies to pass through. You can make the following HPF and LPF adjustments:
      • High: LPF (5k, 6.3k, 8k, 10k, 12.5k, 16k, 20k); HPF (800Hz, 1k, 1.25k, 1.6k, 2k, 2.5k, 3.15k, 4k, 5k, 6.3k, 8k, 10k, 12.5k, 16k)
      • Mid: LPF (25Hz, 31.5Hz, 40Hz, 50Hz, 63Hz, 80Hz, 100Hz, 125Hz, 160Hz, 200Hz, 250Hz, 315Hz, 400Hz, 500Hz, 630Hz, 800Hz, 1k, 1.25k, 1.6k, 2k, 2.5k, 3.15k, 4k, 5k, 6.3k, 8k, 10k, 12.5k, 16k, 20k); HPF (20Hz, 25Hz, 31.5hz, 40Hz, 50Hz, 653Hz, 80Hz, 100Hz, 125Hz, 160Hz, 200Hz, 250Hz, 315Hz, 400Hz, 500Hz, 630Hz, 800Hz, 1k, 1.25k, 1.6k, 2k, 2.5k, 3.15k, 4k, 5k, 6.3k, 8k, 10k, 12.5k, 16k)
      • Low: LPF (25Hz, 31.5Hz, 40Hz, 50Hz, 63Hz, 80Hz, 100Hz, 125Hz, 160Hz, 200Hz, 250Hz, 315Hz, 400Hz, 500Hz, 630Hz, 800Hz, 1k, 1.25k, 1.6k, 2k, 2.5k, 3.15k, 4k, 5k, 6.3k, 8k, 10k, 12.5k, 16k, 20k); HPF (20Hz, 25Hz, 31.5hz, 40Hz, 50Hz, 653Hz, 80Hz, 100Hz, 125Hz, 160Hz, 200Hz, 250Hz, 315Hz, 400Hz, 500Hz, 630Hz, 800Hz, 1k, 1.25k, 1.6k, 2k, 2.5k, 3.15k, 4k, 5k, 6.3k, 8k, 10k, 12.5k, 16k)
      • Sub: LPF (25Hz, 31.5Hz, 40Hz, 50Hz, 63Hz, 80Hz, 100Hz, 125Hz, 160Hz, 200Hz, 250Hz, 315Hz, 400Hz, 500Hz, 630Hz, 800Hz, 1k, 1.25k, 1.6k, 2k, 2.5k, 3.15k, 4k, 5k, 6.3k, 8k, 10k, 12.5k, 16k, 20k); HPF (20Hz, 25Hz, 31.5hz, 40Hz, 50Hz, 653Hz, 80Hz, 100Hz, 125Hz, 160Hz, 200Hz, 250Hz, 315Hz, 400Hz, 500Hz, 630Hz, 800Hz, 1k, 1.25k, 1.6k, 2k, 2.5k, 3.15k, 4k, 5k, 6.3k, 8k, 10k, 12.5k, 16k)
    • Slope: Adjusting the HPF/LPF slope (filter attenuation slope) lets you adjust the continuity of sound between speakers. You can make the following slope adjustments for each frequency band:
      • High-HPF: 6dB/oct., 12dB/oct., 18dB/oct., 24dB/oct., 30dB/oct., 36dB/oct.
      • High-LPF, Mid-LPF, Mid-HPF, Low-LPF, Low-HPF, SW-LPF, SW-HPF: 6dB/oct., 12dB/oct., 18dB/oct., 24dB/oct., 30dB/oct. 36dB/oct.
    • Phase: You can switch phase (normal/reverse) for each preamp channel output signal. This will improve the continuity of sound between speakers.
    • Level: The difference in reproduced levels between connected speakers can be corrected by adjusting the level of each select frequency band.
      • High-LPF, High HPF, Mid-LPF, Mid-HPF: 0 dB to -24 dB
      • Low-LPF, Low-HPF, SW-LPF, SW-HPF: 6 dB to -24 dB
    • Mute: You can mute each preamp output channel individually. When an output channel is muted, no sound is outputted to the connected speaker.

    Auto EQ and TA: Auto EQ uses the included microphone to monitor and analyze acoustics, then automatically fine-tunes all frequency bandwidths and front and rear speaker digital parametric equalization. Auto TA uses this same microphone to automatically adjust for distance between each speaker and the listening position. This entire process occurs in 543 seamless steps in just about 5 minutes to tailor specific musical and acoustic characteristics to your vehicle.

    Position Adjustments: The DEX-P99RS offers the following position controls to accurately reproduce music in your vehicle:

    • Balance Adjustment: You can select a balance setting that provides an ideal listening environment in all occupied seats.
    • Position Selector: The Position Selector function lets you automatically adjust the speakers' output levels and inserts a delay time to match the number and position of occupied seats. You can choose Driver seat, Passenger seat, or Front seat.
    • Time Alignment: The Time Alignment function lets you adjust the distance between each speaker and the listening position, so that sound from all speakers reaches the driver's ears in perfect sync. Time Alignment can be set manually (custom), automatically (Auto TA), or to a default (initial) setting.
      • Initial: factory supplied time alignment setting
      • Custom: adjusted time alignment that you create (0.0' to 155.39')
      • Auto TA: Auto TA automatically estimates the delay from each speaker to the driver's position and adjusts speaker sound output timing accordingly (using supplied microphone)

    L/R Independent 31-Band Digital Equalizer: The built-in 31-band digital equalizer allows you to precisely control the in-cabin acoustics of your vehicle. Unparalleled flexibility is provided through either Left/Right independent setup, or for easier setup L/R common is available. Each frequency band of the 31-band digital EQ (20Hz, 25Hz, 31.5hz, 40Hz, 50Hz, 63Hz, 80Hz, 100Hz, 125hz, 160hz, 200Hz, 250Hz, 315hz, 400hz, 500hz, 630Hz, 800hz, 1k, 1.25k, 1.6k, 2k, 2.5k, 3.15k, 4k, 5k, 6.3k, 8k, 10k, 12.5k, 16k, 20k) can be adjusted from -12 to +12. There are 5 custom memories to allow multiple setups. There is also a Flat setting.

    Note: The 31-band digital equalizer can also be set automatically using the auto-setup microphone.

    Sound Retriever: The Sound Retriever function automatically enhances compressed audio and restores rich sound.

    Note: Apple iPod/iPhone software updates may change functionality results. If you download a newer software version, you may need to reset the head unit and your iPod/iPhone to regain functionality. If this doesn't work, you may need to wait until a newer software update is available.

    Auxiliary Input: The DEX-P99RS is equipped with a front panel 2.5mm stereo minijack auxiliary input (located on bottom of front-panel) for connecting external components, such as a portable MP3 player). AUX must be turned on in the setup menu in order to be selected as a source.

    Radio Functions

    Supertuner IIID AM/FM Tuner: The Supertuner IIID features Feed Forward Control, which avoids multi-path interference. This pre-detection of interference enables quick filter control and results in less distortion. In addition, the Supertuner IIID creates enhanced stereo during multi-path interference, unlike conventional tuners that collapse to mono. Digital processing reduces distortion, and improves Signal-to-Noise Ratio and stereo separation. Advanced analog technology improves signal processing sensitivity.

    BSM (Best Stations Memory): BSM lets you automatically store the six strongest stations under preset buttons 1-6 of the currently tuned band. The tuner has 3 FM banks and 1 AM bank. You can store 6 presets for each bank giving you a total of 18 FM presets and 6 AM presets.

    Local Tuning: Local seek tuning lets you tune in only those radio stations with sufficiently strong signals for good reception. There are 4 level of sensitivity for FM and two levels for AM. The higher settings allow reception of only the strongest stations, while lower settings let you receive progressively weaker stations.

    Display Features

    Motorized Face: The Pioneer Reference-Series DEX-P99RS features a motorized face which electronically slides-down, with the press of a button, to insert and eject a disc.

    Detachable Face Security: This unit features Detachable Face Security. If the front panel is not detached from the head unit within five seconds of turning off the ignition, a warning tone will sound. The warning tone can be turned off in the menu, if desired. A hard-plastic face case is provide to protect the front-panel when detached.

    OEL Display: The Pioneer DEX-P99RS features a white Organic Electroluminescent (OEL) dot matrix display which is easier to see in most lighting conditions. You can easily view file and folder lists from your MP3, WMA, and CD Text-encoded discs, radio presets, or data from your iPod, and XM Radio. The brightness of the display can be set between 0 and 15.

    Multi-Language Display: For your convenience, this unit is equipped with a multiple language display. You can select the language which is best suited to your first language - English, French, or Spanish.

    Adjustable Illumination: You can select the illumination for the head unit's front-panel controls. You can choose between White, Red, Amber, Green, and Blue. You can also adjust the brightness of each color. In addition, you can create a custom illumination color by adjusting the level of three primary colors (Red, Green, Blue). You can even set the unit's button illumination to only turn on when you turn your vehicle's headlights on (using the radio's illumination wire).

    Note: The head unit's OEL display will remain white even if button illumination is adjusted.

    Entertainment Displays: You can enjoy entertainment displays while listening to each sound source. You can choose from the following: Basic Display, Spectrum Analyzer 1/2, Level Meter, or Display Off.

    Ever Scroll: When the Ever Scroll feature is set to On, recorded text information scrolls continuously on the display. It will auto-scroll up to 64 characters. Set this feature to Off if you prefer the information to scroll only once.

    Reverse Mode: If you don't perform an operation within approximately 30 seconds, screen indications start to reverse, and then continue reversing every 10 seconds.

    Illumination Dimmer: To prevent the display from being too bright at night, the display is automatically dimmed when the car's headlights are turned on. You can turn the dimmer function On or Off. The orange/white illumination wire must be connected to the vehicle's headlight circuit in order for this feature to work.

    Display Illumination/Clock Display: When the Clock Display has been turned on, pressing and holding the Source button turns off audio output, but the clock display remains on. When the Clock Display has been turned off, pressing and holding the source button turns the unit off completely. Even if you have turned the radio completely off you can view the clock display by pressing the clock/display button. The clock will then remain On until you turn it back Off. When the unit is On you can select between the clock display or the audio track/tuner display.

    Remote Control

    Wireless Remote Control: The DEX-P99RS comes with an IR wireless remote control. The remote allows you to control the volume, switch between sources, pause the CD, change the display, and adjust the audio. The mute button allows you to quickly lower the volume by about 90% ( function that cannot be performed from the front panel). The remote comes with a dash-mount and steering-wheel mount for added convenience.

    Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input on the rear of the unit that lets you keep your vehicle's factory steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately).

    Crutchfield asked  
    Why did you buy this?

    Top notch piece of hardware. [ CAITLIN  Jan 02, 2019 ]
    This is the best one. [ Jason  Aug 07, 2018 ]
    I needed a head unit with 8 preamp outputs to run all my Pioneer PRO Series speakers with 4 amps. 3 - 4 channel amps & 1 mono amp. 12 speakers (4 tweeters - 3.5s & 4s, 4 - 6.5s, 2 - 8s, 2 - 6x9s, & 2 - 12" subwoofers). [ Todd  Mar 05, 2018 ]
    I had owned this head unit before, and it was by far the highest quality I had ever used. I'm installing a new system in my new car, and I knew this head unit was the only one I needed! [ Elias  Jul 14, 2016 ]
    I had ODR before. [ chinh  Mar 07, 2016 ]

    13 questions already asked

    Not sure about you queation, I been turning off the ilumination few times, when I driving long distances, let me know if this is what you what to know [ CARMELLO  Mar 13, 2018 ]
    I dont see the manual mentioning completely turning off all of the illumination. But there are lots of dimming settings. Page 36-37 of the manual if you can find one online. I havent installed mine yet, sorry i cant tell you exactly how dim it can get. [ Cyrus  Mar 12, 2018 ]
    The Pioneer DEX-99PRS USB input can play MP3, WMA, AAC, and/or WAV files stored on a USB Mass Storage device in FAT16 or FAT32 file system formats--I'm afraid it would not support FLAC or DSD files. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat. [ Larry  Jan 02, 2018 ]  Staff
    Not sure , but for sure you can skip tracks thru the radio and the remote [ CARMELLO  Sep 18, 2017 ]
    Hey Greg. Yes you can control your phone from this unit. Has bluetooth as well as phone input. Youll need to connect phone to unit using btooth with an adapter. Model cd-btb200. Probably available through cruthfield. It enables hands free phone operation. If youll download the manual for the unit it will explain how it functions. Btw this is the best unit ive ever heard! Hope this helps. [ MICHAEL  Sep 18, 2017 ]
    Yes. That's how I play my music, directly from my IPhone 7, via usb/lightning cable. [ Scott  Sep 18, 2017 ]
    I really hope so, i havent installed mine yet. But thats my plan also. I dont see why not. You could try calling/emailing pioneer directly and ask. [ Cyrus  Sep 16, 2017 ]
    You definitely don't need an outboard eq with this unit. It took me a couple of weeks to figure out the settings on this thing but once i did this thing is incredible! Has 5 different eq memories so youll never need more control than this gives you. Big money but its a badass unit. [ MICHAEL  Sep 18, 2017 ]
    While you can use a pair of the DEX-P99RS's pre-amp outputs to provide signal to an external EQ, the stereo already has an elaborate 31 band digital EQ and audio adjustments built-in (automatic time alignment, crossovers, phase, level, etc.) so, using any external EQ would be a little redundant. [ Ryan  May 31, 2017 ]  Staff
    Im not sure what Tidal is but you can play music three ways. Auxillary jack, usb, or CD. I have not hooked it up yet. [ Cyrus  Apr 29, 2017 ]
    It doesn't have built-in bluetooth, but bluetooth can be added with the Pioneer CD-BTB200 Bluetooth Wireless Adapter. [ Forrest  Apr 28, 2017 ]
    Unless you plug it in via usb! [ Scott  Apr 28, 2017 ]
    No, you need the Bluetooth adapter. [ Scott  Apr 28, 2017 ]
    If you use an iPhone you can run digital sound out of the iPhone into the P99's USB input by using a lightening to USB cable. The P99 will display the track info from the iPhone. If your using an android phone you can use a Pioneer CD-BTB200 BT adapter that plugs into the blue IP Bus port on the back of the P99 to stream BT to the P99. There are other 3-rd party IP Bus to BT adapters sold on amazon and ebay too. [ Chuck  Apr 28, 2017 ]
    It depends on a few things: 1. What type of music do you listen to? Country, jazz, classical , oldies work well with a sealed enclosure, Hip hop, rap, and techno work well with ported enclosures. 2. How much bass do you want? enough to blend in well with the mid bass, mids, and tweeters, or enough to break the windshield? 3. How much space in your vehicle are you willing to give up for a sub enclosure? Are you only willing to give up enough space for one sub or for two or more? With your top level equipment list, I would guess you are looking for a sub and enclosure that will blend in well with the rest of the equipment and be able to play a wide range of music accurately. I would go with at least one 10" or 12" sub in a sealed enclosure built to the manufacture's specs and from a well respected brand like JL Audio, Focal, and others. The 500 watts from the Alpine amp will be a good match for a single sub. (I use the PDX-F6 and M12 in my system and the PDX amps are incredible quality for the price.) [ Chuck  Sep 19, 2016 ]
    Tony are you talking bass? If so look at JL Audio W3 or a W7 Crutchfield can help you with this. I would go with a W7. If you are speaking midbass I would go with JL Audio ZR Midbass 8 inch. Love my P99RS> [ john  Sep 19, 2016 ]
    I'm using a JL W6V3 12". It's rated at 600 watts, and I'll be using 500 watts on it and it will sound beautiful/ Crossed over at about 100hz. I ran a JL 10W7 with the same 500 watt JL HD 900/5 amp and it was plenty of power for it. The 12W6 takes a little less power than the 10W7 so I know it will be just right. [ Scott  Sep 19, 2016 ]
    No straight up sq headunit. [ john  Sep 19, 2016 ]
    No this is a Sound Quality Unit. You need amplifiers. No need for jazz,hall etc. Built in DSP also. GREAT UNIT! [ john  Mar 25, 2016 ]
    Not a great answer but I've never used them if it does. [ Jason  Mar 25, 2016 ]
    The p99 support apple devices only, and ull have to buy a special cable for that. Anyhow thats the only way to play flac as the p99 doesn't support it [ ROEE  Feb 17, 2016 ]
    If it has a usb input, and i am pretty sure it does but the specs should say, then YES to the first question. And BTW, I think USB for android and USB for apple are the same but they are different from the new USB-C standard. To the second question, the answer is YES, as I play my Hi-Res files from my handheld AK iRiver android player. But I had to get a cord that fits into the SMALLER front plug. It is NOT 3.5mm (or whatever the typical size is. Check the size of that front or player input and get a chord that has 3.5 on one end and the smaller jack on the other. I found one on the web. Write again if more questions. [ Jason  Feb 13, 2016 ]
    no on both. [ alexander  Feb 13, 2016 ]
    Or just plug your iPhone directly into the jack on the front but you will need a smaller input male plug. [ Jason  Feb 13, 2016 ]
    I don't use an iPhone but when I plug my iPod Classic into the USB port, the head unit becomes the "controller" for the iPod. If you were to use the standard "aux" input from your iPhone, then it'll work as normal and play your apps through the car . [ Eric  Feb 06, 2015 ]
    I do not use my P99RS for iPhone apps. I use it 99% with cds. Make the move you will find Midwoofer in your system!! Love it wished I would have bought one long ago. [ john  Jan 30, 2015 ]
    Yes you definitely can run gen 5 ipod touch through this unit. Use lightning cable that came with ipod and plug into usb in back of unit. Thats my main listening source and it sounds great through this unit! One tip i can give you is to power up your ipod before you turn on head unit. If you dont youll get a no device message on head unit display. [ MICHAEL  Sep 18, 2017 ]
    I don't see why not it all depends how you want to run it. There's a small AUX in the front of the CD player that you can access by holding down the eject button for 5 seconds. you could also purchase the Pioneer CD BTB-200 Bluetooth adapter. I'm not aware of any software updates you could download. I never had tried connecting a 5th gen iPod but I can say I've tried others through the USB connection and it worked fine. The newer year model DEXP99RS is the same as the original. The only CD player that I found that was more superior than the DEXP99RS was the Pioneer ODR Series. I personally have a Pioneer AVH-X7500BT Navigation mounted above my DEXP99RS so I didn't have to purchase the Bluetooth adapter. Typically if you can afford a DEXP99RS getting the screen for that price is a steal. To me it was worth getting the Bluetooth and Navigation in a bundle however if you want Navigation you would need to purchase the Pioneer AVI-U260. I hope I was able to help. Even if it doesn't work perhaps trying some of the things I've said should get you where you need to be. [ CHRISTOPHER  Jan 21, 2015 ]
    Yes I belive the 5th gen will work with no issues. I would use the cable that came with it. All p99rs are the same and there are no updates for these models. [ JASON E  Jan 20, 2015 ]
    I have put the newest iPhone and no problems so your 5th gen should be fine. [ alexander  Jan 20, 2015 ]
    Hi, Peter It is my understanding after talking to my sound guy, that it will work with the use of the USB end which should play it regardless of the end tips as long as the USB is not damaged. [ MARCUS K  Jan 20, 2015 ]
    I have no idea, but if you contact Pioneer directly, they should be able to help you out. [ JUSTIN E  Jan 20, 2015 ]

    You have crossover for 4 pairs of speakers. I ran 6 channel for 3 tweets mids and bass. I ran a miono sub amp for sub. I used Zapco. Of common brands Id buy JL Ausio amps. [ JEFFERY  Jul 17, 2014 ]
    This head unit shouldn't be ran with less than two amplifiers, preferably four though. If using two amplifiers you will need to connect the MID output to your front speakers, your LOW output to your rear speakers, and SUB output to your subwoofer. This can be accomplished by running one 4 channel amp for your component speakers and one single channel (Mono) amp for your sub. The high channel will need to be disabled in the HU setup options. Like this... High -> Disabled. Mid -> Front L/R on 4-channel amp. Low -> Rear L/R on 4-channel amp. Sub-> L/R on 1-channel amp. There are no best amps, it's personal preference when it comes to sound reproduction. Any major manufacturer will work with this HU. I will warn your though, this HU is very high end and in-depth. Setup will take several hours of work to get everything sounding the way you want it after install. [ William  Jul 15, 2014 ]
    Based on what you've asked, I don't think you need to go as far as buying a Pioneer P99, stick with a deh-80prs for less money, less complexity. At your level of experience, you won't know the difference. Find yourself a JL audio 300/4v2 class A/B amp and have a reputable shop do the install. [ JUSTIN E  Jul 15, 2014 ]
    You would need 1 four channel amp or 2 two channel amps for four speakers to get the FULL fuctionality of the p99. Low voltage RCA wiring is needed. [ Adam  Jul 15, 2014 ]
    I'm sorry I purchased the head unit and let a stereo shop do the work so I wouldn't know which route to say go. I have it with a PDX 5 Alpine amp on a Harley Davidson bagger with 2 sets of 6x9's. Sounds amazing and love it but setting it can be a challenge if you're not a technical person. [ MARCUS K  Jul 15, 2014 ]
