Congratulations! You are the now the owner of an exceptional loudspeaker from the audio enthusiasts at
Blaupunkt. Our engineering staff has spent considerable time refining our ProComponent coaxial speakers in
order to introduce great sound to the consumer at an affordable price. Now entering our second generation of
the PCx family of product, we have evolved the speaker design with a new polypropylene cone material for more
accurate sound and more aggressive cosmetics.
We are always very concerned about the end consumer using proper installation techniques for the highest
performance possible from their new loudspeakers. But, MOST important to us are concerns with your safety
and the installation process. Since our Blaupunkt retail dealers have the tools and experience for an optimized
and safe installation, we always recommend they do the final vehicle integration. But, should you choose to
install these products yourself, please take the time to read this manual completely and abide by all precautions.
THANK YOU FOR CHOOSING BLAUPUNKT!
It has been repeatedly proven that surprisingly high audio system performance can be achieved by a moderately
priced set of coaxial speakers. The PCxp coaxials are designed for HIGH POWER HANDLING LEVELS, HIGH
SOUND PRESSURE LEVELS, and FLEXIBLE INSTALLATION CHOICES. Combined with a basic subwoofer
installation, the resulting performance is often outstanding.
The highlight of our new coaxials is the vacuum formed polypropylene cone material offering lighter mass
compared to older paper cones but without the flexing properties common to paper. This gives a much “tighter”
bass response and smoother high frequency response without distortions often found at high listening levels.
Below is a good summary comparing old cones with the new technologies.
KEY FEATURES
In addition to the vacuum formed poly cones is the expansion of our extended pole program. The extended pole
piece of the speaker is lengthened by only a few millimeters but the performance results are significant. The nonlinear fields around the voice coil’s gap are greatly reduced thus improved heat dissipation (higher power
handling) and increased cone movement control (higher power but with “cleaner” response).
V ACUUM FORMED POLY
Vacuum Formed Poly Cones
New “VFP” Vacuum Formed Polypropylene Cones
•Lightweight, and mechanically rigid, poly cones play louder with less power
•Acoustically inert, poly cones do not “color” the sound of the music
•Environmentally resilient poly maintains shape & thickness, ensuring premium
tonal quality for years
Conventional Inexpensive Paper/Plastic Cones
•Non-uniform cone thicknesses (are heavy & often generate internal “bending”
motions)
•Self-resonant materials & construction (standing waves occur yielding strong
tonal shifts)
•Paper & cheap plastic cones warp & change mass over time due to swings in
temperature & humidity (degrading performance)
Speaker Cone
Extended Pole Design
New “EXP” Extended Pole Design
•Increased cone travel for higher “clean” sound pressure levels
•More symmetrical magnetic operating field for lower distortion
•Better heat dissipation offering higher power handling capability
Conventional Magnetic Pole Design
•Limited linear cone travel (high level distortion at lower volume levels)
•Uneven magnetic field distribution throughout cone travel (common distortions)
•Average heat dissipation (therefore only average power handling)
SYSTEM PLANNING
The largest possible impact on any audio system (home or car) is the tonal quality of the loudspeakers, their
respective placement, and their overall efficiency (loudness). A 4x20 watt amplifier and four dual-cone speakers is
never going to make an impressive performance. Many newer cars have acceptable speaker locations but a
factory 4x10 watt system with dual cone speakers is just not going to impress anyone. Install your new coaxials
and establish a pleasing mid and high frequency response, and with good imaging properties. To move up in
performance, add an outboard subwoofer and amp to give an emotional sensation of “strength” to the audio
system.
SYSTEM IMPLEMENTATION
Speaker configurations are a common problem in
autosound installations. We want to achieve a sound
field in front of us (like a live concert) as compared to
sound partly from the front and partly behind us.
This dictates good midrange and tweeter speakers in
front, usually mounted in the doors for good left/right
balance, with high-pass crossovers set greater than
80-100 Hz. The best stereo image will occur when
the front speakers are spaced as far forward as
possible attempting to achieve nearly equal distance
from the speakers to the listening position. For deep
bass a subwoofer is required but is nearly always
located behind us in a rear trunk or rear hatch area. If the subwofer crossover is too high in frequency male voices
can be heard “gurgling” out of the subwoofer speaker and therefore pulls the sound-stage to the rear of the car,
which is very unnatural and therefore undesirable.
AMPLIFIER POWER
Amplifier choice and power is important but less so compared to speaker choice and placement. Matching the
rms (continuous) power capability to that of the speaker is important but it should be noted that “under-powering”
a system can often damage more tweeters than providing slightly more power than stated by the speakers. If the
speakers are rated to 50 watts rms, you can often run 60-80 watt rms amplifiers without concern IF the amps are
not driven into clipping (deep distortion). IMPEDANCE is the electrical resistance to AC current flow and is
typically 4 ohms for most car speakers. Impedance loads should not fall below the recommended minimum load
tolerances of the amplifier (commonly 2 ohms) or the amplifiers will heat up and sometimes shut down.
SOUND QUALITY VS. LOUDNESS
All well designed sound system can provide good sound quality and still play loud. Above about 120 dB (decibels)
the sound isn’t perceived as getting much louder due to the non-linearities of the human ear. A four loudspeaker
system with the per-speaker efficiency rating of 90 dB (1 watt/1 meter) will often achieve about 110-115 dB if
driven by 100 watts per speaker channel. (Although often debated, this is more than enough sound pressure level
for most humans to enjoy and can easily cause hearing loss if listened to at such levels for hours at a time.)
SYSTEM DESIGN GUIDELINES
We always recommend you have your Blaupunkt speakers professionally installed but
the installation process is often so easy that the average consumer can achieve success
with little trouble. Regardless of the person installing, you should be sure to review the
following points before proceeding with the installation:
■ READ THE MANUAL! Understanding the product and installation limitations before
lifting a screwdriver.
■ WEAR SAFETY GLASSES AT ALL TIMES - Flying debris are always dangerous.
■ PROTECT THE VEHICLE - Always disconnect the negative battery cable before
starting any kind of installation work. This prevents a possible high current electrical short (potential fires).
■ HEAT - Keep all speakers away from nearby hot components such as amplifiers or vehicle components that
heat up over time such as hoses, high current wires, and braking system components.
■ GIVE YOURSELF LOTS OF TIME - Rushing to complete an installation nearly always ends up with problems.
■ DO NOT LISTEN AT HIGH SOUND LEVELS FOR A PROLONGED TIME - If connected to high power
amplifiers, these speakers have the potential to cause permanent hearing loss after listening at maximum
volume levels for several hours.
SAFETY CONCERNS

Subwoofer
Before disassembling your beautiful new car you need some basic installation knowledge
and skill with common hand and power tools. Following such basic installation tips and
warnings will prevent possible damage to the vehicle and also prevent possible fires.
■ AGAIN...READ THE MANUAL! There is a lot of helpful information in this manual that
will save time and prevent problems later.
■ COVER THE VEHICLE WORK AREAS - Use fender covers or blankets to protect the
work areas from scratches or dings.
■ DISCONNECT THE (-) LEAD ON THE BATTERY - No sparks or fires please!
■ “REVIEW” THE INSTALLATION - Before using any tools or moving vehicle components,
take five minutes to review the installation intentions (e.g., verify that an enclosure will fit
in an area of a car before tearing out all the interior).
■ “REVIEW” THE VEHICLE - Before drilling any holes or cutting into any surfaces, make
sure there are no fuel or hydraulic lines behind the surfaces. Also make sure there are no wires routed directly
behind or near the desired mounting area (remember...screws can often extend 1-2 inches behind the
mounting surface).
■ ENSURE PROPER FIT - Before cutting or drilling, make sure the speaker will physically fit in its desired
location. Check for clearance around rear deck torsion bars or other structural elements.
■ EVERY CAR IS ASSEMBLED DIFFERENT - Every auto manufacturer uses different assembly techniques.
Take care in removing/modifying all trim panels and mounting surfaces since they often use unique screws or
snap fasteners that are difficult to replace if they are lost or broken.
■ BE CAREFUL WITH CABLE ROUTING - When routing audio cables, make sure RCA and speaker wires are
routed away from high current power lines for audio amplifiers and vehicle systems lines when possible. This
will help prevent noises from creeping into the audio system, plus prevent potential damage to the vehicle
wiring itself.
■ BE CARFUL WITH ALL CONNECTIONS - When making connections, make sure each connection is clean
and properly secured. Observe all polarity markings carefully to ensure proper end performance.
■ CAUTION - FUEL TANKS AND FUEL LINES ARE NOW LOCATED DIRECTLY BENEATH THE REAR DECK IN
MANY CARS - CHECK FOR ADEQUATE CLEARANCE BEFORE EVEN CONSIDERING SUCH A MOUNTING
LOCATION!
INSTALLATION WARNINGS!
We strongly recommend that you have your Blaupunkt subwoofers professionally installed. If you choose to do your
own installation please note the following important information:
■ Before cutting any trim or metal make sure your final installation will clear all moving parts, factory cables, wires, and
hoses.
■ Be sure to leave enough slack in the wiring to prevent the need to pull or stretch wires if service is needed later.
■ Tie down all loose wires with nylon wire ties to prevent them from getting caught in moving parts or shorted out due
to abrasions from moving over time.
■ Never mount speakers in a vehicle’s wheel wells or areas where they may be subjected to moisture or road spray.
■ Proper speaker polarity must be observed. The polarity positive side is marked by a (+) symbol or a red colored dot.
At low frequencies woofers out of phase will acoustically cancel one another thus resulting in little bass output.
■ Although components used in Blaupunkt speakers exceed most production quality standards, speaker frames can
still be twisted by improper installation on uneven surfaces.
■ This can occur when surfaces are heavily padded or carpeted and the screws are unevenly tightened or over
tightened. The results will be a damaged voice coil assembly due to knocking it off center.
■ When installing more than one speaker per amplifier channel be sure that the combined impedance values do not fall
below the recommended minimum speaker load values of the amplifier (most amplifiers will overheat over time and
possibly shut down with loads below 2 ohms).
■ Speaker wire size should be sufficient to carry the full power of the amplifier (16 gauge or larger is sufficient in about
90% of all audio systems assuming <100 watt amplifiers and wire runs under 20 feet)
■ Speaker wires should be electrically and physically isolated from the vehicle and routed away from any factory wiring
that carries high currents or noises (e.g., ABS brake systems and engine computer signals)
FINAL SYSTEM TEST & TROUBLESHOOTING
Once the system is installed, turn on the total audio system main power switch and SLOWLY turn the volume up using a
music selection with a full range of frequencies. If you experience any problems take corrective action immediately to
prevent damage to the speaker, amplifier, and vehicle.
