Pioneer  DEH-P4000UB

awesome unit, tons of features, sound quality is unreal, definitly worth the money, I have this unit running 4 pioneer 6x8 speakers along with two tweeters and a 10" sub with a kicker amp and this unit has really brought my car to life.

i just added this unit to my car. I actually just put it in 2 hours ago and i love it. i have the one with the blue lights and text. this unit is clean! looks clean, sounds clean. its not as loud as my old pioneer was. i think it only has 14w rms going to the speakers. but the sound quality is just awesome, if you do it right. i have the pioneer ts-c1653 6 1/2" component speakers in the doors and roadmaster 6x9s in the rear. i eventually want to replace the 6x9's with pioneer 3 ways. anyways this system rocks. im very pleased. it also comes with a usb cable. and its also i pod ready with the aux right up front. no adapters required. just plug and go.

This is a great overall cd player. there are plenty of options to make the audio sound great and has all the necessary buttons on the face. if your looking for a budget cd player and want more for less, this 1 is worth the cash.

wow, this is a really nice headunit. i got this in my '96 s10 so i needed a dash adaptor kit, i got a standard cab and i got 2 12's squeezed in there, haha, but this HU keeps everything sounding good and really improved the sound of my door speakers and my 4x6's

Got This Unit About A Month Ago, Very Pleased!!! Nice and Easy To Operate. Excellent Features Like Title Scrolling Of Song Or Artist. The Blue Neon Lights Look Cool And Match The CRUNCH Amp And Speakers I'm Using. .Great Deal For Price And OCS Is By Far The Best Place To Buy.

AWESOME product! Just put 1 in my '02 Spyder, even with the factory amp and speakers, it sounds twice as good as the original HU and has more features. The display looks pretty bad*** as well

Hey guys/gals I had an older pioner head unit and I put this new unit in mt 08 colorado and I found this to be far supperior than even the oem. For the sound and setting are just what I needed to match with the 4000watt pyle amp that now it sounds sick. (in the good way)

i really like this stereo! i bought the same one at walmart and didnt' kno i would get it here for $40 cheaper! i love this thing its amazing. great sound quality! good features and u can plug anything into this and play music from it. i have a sub hooked up to it and the quality is great and u can do about everything almost to tweek the sound and loudness of all speakers

i got this knocking in my car its pretty good i got 2 pioneer 12" subs pushing n its goooooood if u looken for qulity n cheap this is for u n it contols ur ipod i give it a 10

I bought this to replace another deck. Its great took me a bit to get use too but its great. Ipod controls are good and so is my satilite radio controls. I would buy it again.

I bought this unit to play .wav files from USB hard drive. I have 111 GByte WD Passport drive formatted FAT32 with 52GB of music, hooked up and running good. My drive did not work with included USB extension cable due to voltage drop, but i was able to mount the drive closer to the stereo without using that extension. The stereo has issues with fast forwarding some mp3 files. Buttons and screen are too bright! The dimmer does not make much difference - useless to me. The built in up/down/left/right buttons into the volume knob are annoying - i keep changing the track when I want to adjust the equalizer. The unit has 15,000 file limit, 250GB drive size limit and 500 folder limit. Drive load time is quick, about 10 - 20 seconds from ignition on to sound playback. Built in amp was big disappointment, harsher and weaker than my older Pioneer DEH-P3700MP. Even with EQ set to flat, the highs still seem boosted to me. I am planning to buy 4ch. external amplifier. Does not support gapless playback. Wire harness plug is identical to my older Pioneer stereo, so install was plug and play.
