2-DIN Chassis: The DPX308 has a 2-DIN chassis (also known as
"Double DIN"), and will fit in many vehicles with a large dash opening. The unit
can be ISO-mounted using factory brackets, or Euro-mounted using the supplied

13-digit fluorescent display.
Variable Color Illumination: The Kenwood DPX308U features
variable color display and button illumination. You can choose from one of 24
preset colors, have the unit scan through all 24 preset colors continuously, or
customize your own color (RGB: 0-9). The display and button illumination can be
set to the same color or set independently.

Audio Section
24 Bit D/A Converter: The Kenwood DPX308U utilizes a
24-bit digital to analog converter for superior CD sound quality.
MOSFET Amplifier: The Kenwood DPX308U is equipped with a
MOSFET amplifier. Compared to conventional power supplies, the MOSFET
amplification circuit is smaller and more efficient, and it delivers increased
power with less distortion and absolutely zero on/off switching noise. More
power means louder and cleaner music at higher volumes because you're not
pushing the limits of the amplification circuit. The power output specs for the
DPX308U are as follows:
- Full Bandwidth Power: 22 watts RMS x 4 channels (at 4
ohms, 20-20kHz, 1% THD)
- Maximum Output Power: 50 watts x 4 channels
(200 total watts)
Rotary Volume Control: The CD receiver uses a rotary volume
control that increases and decreases the volume of the stereo from 0 to 35. The
rotary knob also controls other audio settings such as Balance, Fader, Bass,
Mid, Treble and preset EQ settings. In addition, the rotary knob allows you to
scroll through and select your music tracks when the Music Search function is
activated.
Volume Offset: The level of each source may be independently
adjusted to prevent radical leaps in output volume when switching from one
source to another. The available settings range from -8 to 0 (-8 to +8 for Aux
source).
Speaker Settings: The Speaker
Setting function tailors the System Q Sound Control settings according to the
type of speakers in your vehicle. You may select a Speaker Setting of 'SP-Off'
(flat/off), 'SP-OEM' (for OEM factory speaker systems), 'SP-6x9/6' (for systems with 6"
and 6"x9" speakers), or 'SP-5/4' (for systems with 4" and 5" speakers).
System Q Sound Control: Eight EQ curves are preset into
memory, allowing you to recall the best preset EQ curve for different types of
music. Each preset has its own level settings for bass (100Hz), midrange (1kHz),
and treble (10kHz). You can choose from the following preset EQ curves - Rock,
Pops, Easy, Top 40, Jazz, Natural, Game, and User.
Detail Audio Control: The Kenwood DPX308U features
independent Bass, Treble and Midrange control when the System Q Sound Control is
in User mode. The Detail Audio Control allows you to adjust the following
settings for the Bass, Treble and Mid frequency levels.

Bass Boost: In addition, The Kenwood CD receiver features a Bass Boost control that can be set
to the following levels - LV1, LV2 or Off.
Source Tone Memory: This feature allows you to store System
Q bass, middle and treble tone settings for each source (CD, Tuner, USB/iPod, and Aux).
Supreme Setting: When MP3/WMA/AAC files encoded at a low bit
rate (less than 96 kbps, 44.1k, 48kHz) are played, the Supreme Setting function
restores their high frequencies so the sound quality is closer to files encoded
at a high bit rate. The processing is optimized for the compression format and
the bit rate used. When the Supreme Setting is Off, the unit plays the original
sound stored in the audio file.
Selectable 2V Preamp Outputs: The DPX308U features Front and
Rear/SW preamp outputs. The Rear/SW preamp output allows you to adjust from a
full-range rear speaker preamp output to a low-pass, non-fading subwoofer preamp
output.
Subwoofer Controls: The Kenwood DPX308U offers the following subwoofer controls, when you have the
unit's subwoofer preamp output activated.

subwoofer output between 180-degrees (Reverse) or 0-degrees (Normal).
- Subwoofer Level: Once the Subwoofer preamp output is
activated, you can independently control the

2, 3) and 1 AM bank for storing presets. The Kenwood DPX308U offers two preset
