996 C4 coupe 1999 Audio enhancement


Recommended Posts

Hi have just bought the above that has a CD 210 radio with boot mounted CD changer. Underneath the radio is a unit with various equaliser settings, like Hifi and Room.

I haven't got an audio manual to work out how to use it.

Can anyone either suggest what it is and or where to get a manual or part number so I can research it.

Many thanks.

Digital Sound Processing (DSP)
lDigital sound processingl (DSP) enabling the digital processing of speech and music in the amplifier is another optional extra. The sound package forms the basis. Apart from further acoustic adaptation to the vehicle, this function also allows spatial acoustic simulation. As a result, pre- and  postreflection can be mixed artificially to give, for example, a concert hall effect. Different acoustic spatial effects can be simulated with DSP. On request, acoustic adjustment can be selected to optimize this spatial impression for the driver's seat or passenger's seat.
 
Furthermore, programmed acoustic patterns can be stored and called up again. The separate operator unit is housed in the center console at the front of the passenger compartment. Different acoustic adjustments can be selected using the various buttons provided.
 
Other equalizer functions (selectable frequency band) with several amplification levels can be called up using the optional extra information and navigation system (PCM). The DSP facility is operated entirely from the screen controls. The CD player (CD radio or CD changer) is recommended for
optimum DSP sound quality).

Functions:
 
DSP button
When the OSP facility is switched on, the functions last activated are switched on again.
 
DYN button
Speed-dependent volume and acoustic control is switched on/off using this button.
 
POS button
The row of LEOs briefly light up when the POS button is pressed. The listener's position can be spatially adjusted to the driver, passenger, or the middle of the vehicle using the arrow buttons. The LEOs are lit according to the setting.
 
HiFi-classic-pop buttons
A permanently defined acoustic pattern is produced when these buttons are actuated. The function can be deactivated by selecting a different acoustic pattern.
 
User button
The user function is used to create individual acoustic patterns using the room and echo buttons. Spatial impression and echo effect can be changed from low (lefthand LEO) to high (all LEOs) using the arrow buttons.
 
MI, M2, M3 memory buttons
Permanently defined or individually created acoustic patterns can be stored and called using these buttons. The listener's position (POS button) and speed-dependent volume control (OYN button) functions can be stored in the memory together with the acoustic patterns.
 
Storing: Press the desired memory button for approx. 2 seconds.
Selecting: Press the desired memory button.

      Quick background: I just replaced most of my 2004 996TT Cab audio components (Kenwood H/U, Focal Evo 3-way speakers in door and dash). While I appreciate having Bluetooth and a back-up camera, not loving the sound as much as my wallet is telling I should be. I know it's a cab and the sound won't be winning any awards, but I'm still hoping to improve it. Which brings up the much lamented subwoofer conundrum and my question...

      After doing quite a bit of searching and forum diving, I didn't see anyone who tried to reuse/repurpose the factory Bose enclosure in the passenger foot area. The stock speaker is 4x6 that points down. Is there anything that would prevent me from using the same enclosure by covering up the existing speaker and port holes, and cutting an opening for an 8inch woofer that would point out towards the passengers feet (see pic; paper represents speaker size)? The enclosure is shaped a bit like a parallelogram. Taking some basic W / L / H measurements, the enclosed volume is roughly 0.29 cubic ft. Most of the shallow-mount 8in subwoofers I've researched on Crutchfield require a minimum of 0.2 cubic ft. (sealed), so while not ideal, I should be within specs.

      What am I missing? Thank you very much for your thoughts!!!
