Our take on the Pioneer DEH-P4500MP

Add some variety to your road music! Pioneer's DEH-P4500MP CD receiver plays your MP3 discs as readily as it plays your CDs. The large readout on the fold-down, detachable faceplate displays the MP3 text info, so you can find your favorite tracks quickly.

If you love radio, you'll be knocked out by the reception of the Supertuner IIID digital AM/FM tuner. Considering satellite radio? You'll appreciate the built-in controls for an optional XM Satellite Radio tuner. (An XM tuner, antenna, and subscription are also required.)

All of your music will sound awesome when powered by the MOSFET50 internal amp. Shape the sonic contour with Easy EQ's preset tone curves and 3-band equalizer, for personalized highs, mids, and lows. Turn on Front Image Enhancer for better stereo imaging, making it sound like you are sitting "front and center." Pioneer's intuitive menu design makes using the sound control features a breeze!

Use the wireless remote to control the receiver without taking your eyes off the road. You can get hours of non-stop music from 6 or 12 of your favorite CDs, when you add a Pioneer CD changer.

Pioneer DEH-P4500MP Reviews

High quality receiver

Sunkistboy from Saegertown, PA on 9/16/2008

This was the first CD player I ever bought for my car. I had it for three years and it never let me down. 22 watts x 4 channels is great power from an in-dash receiver. The MP3 playback capability was a godsend since you could put a whole lot more music on one CD compared to an audio CD. Allows you to adjust bass, midrange, and treble and also has a 3 band equalizer that allows you to change the frequency level that is accentuated. XM-radio ready though I never used that feature. Fairly straight forward to install if you have the wiring color diagram. Front and Rear channel preamp outputs. Removable cover. This receiver is the best receiver I've ever used in a car. A whole world better than factory stereo's and better than all the aftermarket CD players I've seen in other people's cars. I sold mine only because it is a huge pain to put an aftermarket stereo into a 2004 impala because they tie the head unit into the cars computer. Those silly GM engineers.

MOSFET50 Internal Amplifier: This receiver is equipped with a 50 watts x 4 (peak) MOSFET amplifier for low distortion, high power output. The amplifier is strong enough to power small subwoofers to moderate volume levels in compact cars and pickups. For higher volume levels from subwoofers, an optional amplifier may be connected to the preamp outputs.

XM Satellite Radio Tuner Compatible: This unit can control an optional Pioneer XM tuner (sold separately). XM Satellite Radio programming features 100 channels of digital-quality music, news, talk, sports, entertainment, and children's programming. For a monthly subscription fee, you will be able to receive the XM signal in your car using an optional XM antenna and tuner.

Easy EQ Curves: This model has "SUPER BASS", "POWERFUL", "NATURAL", "VOCAL", "CUSTOM", and "FLAT" preset EQ curves. The "CUSTOM" curve is one that you create and store in memory. A separate "CUSTOM" curve can be created and stored in memory for each source.

3-Band Parametric Equalizer: This unit includes a 3-band parametric EQ with Selectable Q Factor. You may select a low (40, 80, 100 or 160Hz), mid (200, 500, 1k or 2kHz) and high frequency (3k, 8k, 10k or 12kHz) to boost or cut within a range of -6dB to +6dB. The Q factor (slope of the boost or cut) may be selected from one of the following four options: 2N (narrow), 1N, 1W and 2W (wide). Selecting a narrow (steep) Q factor results in frequencies around the center frequency to be affected less by the boost or cut than they are with a wide Q factor. This feature is useful for taming frequency response problems caused by the dimensions, materials and speaker locations of a vehicle.

F.I.E. (Front Image Enhancer): This feature enhances the front image by cutting mid- and high-range frequencies to the rear speakers, limiting their output to low-range frequencies. You may select a cutoff frequency of 100, 160 or 250Hz.

Adjustable Loudness: You can select "Low", "Mid" or "High" for different levels of loudness compensation.

Source Level Adjustment (SLA): This function lets you adjust the volume level of each source to prevent radical changes in volume when switching between sources. Settings are based on the volume level of the FM tuner, which remains unchanged.

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.

MP3 Playback: This unit can play MP3 files recorded on CD-ROM, CD-R, and CD-RW discs in ISO9660 Level 1/Level 2, Joliet, and Romeo formats.

CD-R/CD-RW Skip Function: Some CD-R/W recorders allow you to assign skip ID tags to tracks that you never want to hear. When a track has been assigned a track skip ID, compatible units will recognize the skip ID information and skip over that track. This player recognizes track skip IDs, so CD-R and CD-RW discs with skip ID information will be played back as intended.

Disc Title Memory: Titles of up to 8 characters each can be entered into memory for up to 48 discs. When a compatible changer is connected, titles of up to 8 characters each can be entered into memory for up to 100 discs in the changer.

Optional Aux Input: When used with item 130CDRB10 (sold separately) or item 130CDRB20 (sold separately), this unit can accept input from an auxiliary source, such as a portable CD or MD player. When item 130CDRB10 is used, a CD changer cannot be connected to this unit. Item 130CDRB20 allows you to connect an optional Pioneer CD changer and an auxiliary source to this unit.

Warning Tone: If the front panel is not detached from the head unit within 5 seconds of turning off the ignition, a warning tone will sound. This feature can be turned On or Off.

Changer Controls

ITS (Instant Track Selection) Programming: The ITS function can be used to program automatic playback of up to 99 tracks per disc for up to 100 discs. With changers sold before the CDX-P1250 and CDX-P650, up to 24 tracks can be stored in the playlist.

Disc Title Memory: Titles of up to 8 characters each can be entered into memory for up to 100 discs. 

CD Text Display: When used with a CD Text compatible Pioneer CD changer, this unit will display the titles of CD Text encoded discs that are played in the changer. When playing a CD Text disc on a CD Text compatible changer, you cannot switch to the Disc Title Input mode. CD Text disc titles, artist names and track titles longer than 16 characters may be scrolled to reveal the entire string of text.

CD Sound Quality Adjustment: Using the "COMP" (compression) and "DBE" (dynamic bass emphasis) functions, you can adjust the playback quality of the changer. Each function may be set to one of two levels or off. The "COMP" function compresses the audio signal to eliminate distortions caused by the imbalances between the loudest and softest sounds when played at high volumes. The "DBE" function boosts bass frequencies to give your music a more full sound.

Note: For these functions to work, they must be supported by the Pioneer CD changer.


Display Illumination/Clock Display:When the Time Display has been turned on, pressing and holding the source button turns off audio output, but the clock display and button/face illumination remain on. When the Time Display has not been turned on, pressing and holding the source button turns the unit off completely.This unit's clock and night illumination are "keyed" only when the Time Display has been turned on. When the Time Display has not been turned on, the unit is off, and power is supplied to the power and constant wires, nothing illuminates.
