THANK YOU FOR CHOOSING BLAUPUNKT!

KEY FEATURES

– 2 –

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 overdrive components in order to introduce great sound to the
consumer at an affordable price. Based upon our previous generation of components, we carryover the rugged design but
enhance it with the new AIP woofers and MMT tweeter mounting system.

Not only do we offer you a great product but also a supportive owners manual. Although technically informative, we are
also are very concerned about the end consumer using proper installation techniques for the highest performance possible
from their new loudspeakers. MOST important to us are concerns with 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.

It has been repeatedly proven that remarkably high audio system performance can be achieved by moderately priced
components. The overdrive components are designed for HIGH POWER HANDLING LEVELS, HIGH SOUND PRESSURE
LEVELS, and FLEXIBLE INSTALLATION.

One feature of our new components is the aluminum injected plastic woofer cone material offering lighter mass compared to
older paper cones but without the flexing properties common to paper. This gives a much “tighter” midrange and bass
response without distortions often found at high listening levels. Below is a summary comparing conventional cones with
the new technologies.

In addition to the Aluminum injected plastic cones is the “MMT” Multi Mount Tweeter program. Such a tweeter design
ensures that nearly every possible installation requiring a remote component tweeter is easily, and attractively, completed.
The key to this program is the large plastic “nut” that allows you to “screw in” the mounting cups for the tweeter by feel. No
more tiny screws that are difficult to see and attach once the cup is mounted to a door panel for example.

New “AIP” Aluminum injected Plastic Cones

• Lightweight, and mechanically rigid, plastic cones play louder with less power

• Acoustically inert, injected plastic cones do not “color” the sound of the music

• Environmentally resilient plastic 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)

Aluminum Injected

Plastic Cones

• Surface mount the tweeter for quick and simple installations

• Dash mount the tweeter using the universal opening adapter that drops into 3.5", 4", 4x6",

5.25", and 6" openings.

• Flush Mount the tweeter to disguise the install with a clean, low profile, factory looking design.

• Flush-Angle Mount provides optimized cross-car high frequency imaging due to the angle

mounting of the tweeter with deep cups for thicker door panels.

Multi-Mount Tweeter

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!

SAFETY CONCERNS

INSTALLATION WARNINGS!

– 3 –

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.

For most installations, simple hand tools are adequate if replacing the factory speakers. If the factory locations, or other
convenient mounting locations are not used, you will need power tools for drilling and cutting plastics and metal. A good
starting list is summarized below:

■

Tape measure and ruler

■

Marking pen and starting punch

■

Phillips and flat blade screwdrivers (small and medium sizes)

■

Nylon wire bundle ties

■

Pliers: standard vice-grip and needle nose styles

■

Light-duty trim pry-bar for removing door trim

■

Cutting shears or nibbling tool for cutting thin and medium gauger metal

■

Wire cutters, wire strippers, electrical tape, crimping pliers and appropriate
crimp-on terminals

■

Power drill with appropriate sized drill bits (1/8", 3/16", and 1/4" to start)

■

Electric jig-saw (sabre saw)

We strongly recommend that you have your Blaupunkt speakers 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 street 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 will not
damage the amplifier should they be too low (i.e., a common minimum impedance value of 2 ohms is common).

■

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 of the following problems take corrective action
immediately to prevent damage to the speaker, amplifier, and vehicle.

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. The first major improvement comes with the addition of a strong low frequency performance which
give the emotional sensation of “strength” to the audio system. Often many newer cars have acceptable coaxial speakers in
acceptable mounting locations. By adding a subwoofer speaker and amplifier, the system, although only moderate
performance, becomes surprisingly pleasant for most listeners. To move to the next step up in performance you must install
some good component speakers for the mids and highs (“satellite” speakers) then add a separate subwoofer speaker for the
lows.

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 subwoofer 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.

MULTI-CHANNEL SYSTEMS
Moving up to amplifiers around 4x50 watts on the satellite channels with component speakers is a common and acoustically
rewarding step. The improvements in acoustical left/right balance and stereo imaging are quickly obvious. By adding a
dedicated subwoofer amplifier the perceived “strength” of the system is
often dramatic.

In order to achieve such a multi-channel system a dividing network must
be installed that keeps the low frequencies out of the midrange speakers.
Such a “crossover” network directs the higher and lower frequencies to
their respective drivers. Such a crossover can be “passive” (simple coils
and capacitors) that limit the operating frequencies seen by their respective
speakers. A crossover can also be “active” where an electronic box must
be installed in front of a dedicated amplifier and process the signal via
small signal RCA cables before its amplification. In general, active
crossovers are most common for the low/mid transition area because they
best filter the low frequencies and are physically small compared to the
passive equivalent. Passive crossovers are most often used where they
provide adequate filtering in the mid/high frequency transition with satellite
midranges and their tweeters. Passive crossovers at these higher
frequencies require only small coils and capacitors so they are easy to
install and perform well.

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 manufacturer’s recommended minimum impedance or the amp will heat up and sometimes shut down (2
ohms/channel is common).

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 per­speaker 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.)

WIRING & TESTING

INSTALLING COMPONENT SPEAKERS

Component speakers are used to ensure a no-compromise performance
of the woofer and tweeter. Each component is able to be acoustically
optimized and independently located as compared to a coaxial which has
many trade-offs.

The objectives of component speaker mounting include:

■

Positioning the speakers for best left/right balance, front imaging, and
frequency response.

■

Mounting both the tweeter and woofer to a solid surface to prevent
buzzing a rattling. Also, you do not want to have the speaker banging
around in the door.

■

Make sure there are no air leaks between the front and back of the
woofer cone to prevent bass loss. Poor air seals results in a “hollow” or
“muffled” sound quality from the woofer.

■

Protect the speakers from the environment. Water is shed from most
door speakers easily but if allowed to “pool” is can easy soak and rot
the spider and rust the basket and back plate assemblies.

■

Ensure the wiring is correct. Woofers out of phase with other woofers in
the vehicle create a “phasy” sound. Tweeters out of phase create a
notch in the frequency response also.

WIRING THE SYSTEM

Your Blaupunkt speakers have crossovers with clearly marked terminals
and keyed spade lugs for connecting to the speakers. Be sure to use
them to ensure proper polarity and reliable long term electrical
connection. The crossover provided is optimized for these speakers. If
you chose to by-pass the crossover, a crossover point of 4 kHz and 12
dB/octave active filter should be used. DO NOT use alternative passive
units - they may flip phase and overdrive the tweeter assemblies.

As for the vehicle, speaker wiring MUST ALWAYS be isolated from the electrical system and chassis. It should also be
routed away from any factory computers and high current wiring to prevent stray noise pick-up into the speakers. Finally, be
sure to maintain impedance loads equal or greater than the minimum values allowed by the radio or amplifier.

FINAL SETTINGS

The Blaupunkt crossover provides for small “trimming” of the tweeter gain
and crossover frequency. Tweeters mounted high the door or dash
usually requires less gain so the “-3dB” setting drops the volume
accordingly. Similarly, the frequency where the tweeter “comes in” can be
set and this is purely personal.

SYSTEM TEST

Once installed, turn on the radio and SLOWLY turn up the volume while
playing a favorite music track.

■

If the music is heavily distorted or occasionally drops out check for
short circuits of the wires to the vehicle chassis or to themselves.

■

If nothing is heard at all, but the power lights come on the amp, check
input signal lines to the amp then all connections between the amp and
speaker for open or short circuits.

■

If the system still does not turn on at all, contact Blaupunkt technical
support at our number on the warranty page.

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 plan ahead for the installation making the proper choice of location before moving into the car in any way.

INSTALLING WOOFERS IN FACTORY LOCATIONS

Most of today’s vehicles have speaker grilles which
are designed to compliment the interior design. As for
mounting locations, many of these openings are in
reasonably good acoustical locations as well. Often
the grille is held on with small clips or screws. To
remove a clipped on grille, gently pry up on the side
with a flat blade screwdriver. Some grilles are an
integral part of the door panel such that the entire
panel must be removed to expose the speaker. Once
the factory speaker is exposed, remove the hardware
and replace the factory unit with the new Blaupunkt
unit. Carefully replace all hardware and replace the
accompanying trim.

INSTALLING WOOFERS IN NON-FACTORY
LOCATIONS

If you chose to install your new speakers in locations
other than the factory locations, make certain the new
location is clear of obstructions in front of (e.g.,
armrests, window cranks) and behind the speaker
(e.g., door wiring). Once the location is chosen,
carefully cut the proper hole size, install the crossover
in a convenient location, route and connect all wires,
mount the speaker, install the grille, and re-install any
panels or factory components.

DOOR MOUNTING

Door locations are most often favored because of the
tonal quality and imaging advantages they provide
compared to the typical dash locations. Unfortunately
the woofer is forced into the very bottom of most
doors because of space constraints. This low woofer
install creates a dilemma because the tweeter should
be kept close to the woofer to maintain unified sound
field but this often places the tweeter firing sound into
the legs of the passengers thus high frequencies are
lost. If the tweeter is too high (e.g., the top of the
door) the listener is overwhelmed with high
frequencies and the left/right balance is damaged thus
accurate imaging is lost.

A compromise between left/right balance and good
high frequency response must be achieved and this is
with the tweeters just above knee level in most
installations.

REAR DECK MOUNTING

Rear deck, or rear sail panel installations, are easily accomodated with these speakers since the woofers easily can easily
drop into the factory holes or may require a simple adaptor plate which can be purchased or formed from wood. Surface
mounting the tweeter does not require any significant holes so a factory look can be maintained in most cases.

We have taken tremendous pains at trying to understand the problems in system installation and design our products to
help, not hurt, the installation process. Using our new

MMT (Multi Mount Tweeter) mounting system, we are able to quickly

and easily install the tweeter assembly in nearly every possible factory, and custom, location. The key to the install is our
“cup mount” process where we first mount the tweeter to a cup via a small screw. This is easily done outside the vehicle.
Then this tweeter assembly can be easily moved into place and the mating nut design can be screwed on, even with “blind”
installs such as door panels that are only partially removed.

SURFACE MOUNT

This method is used in installations where room is not available behind
the tweeter to drill and recess a mounting cup. Although not as visually
attractive as a flush cup, it performs well and is quick to install.

To make a surface mount, a hole is drilled for both the screw and signal
wires. The screw is simply run through the surface material and into the
back of the tweeter. A washer should be used to ensure the screw will
not pull through the surface over time.

DASH MOUNT

Often, the user simply wants to mount the woofers in the door panels and
the tweeters in the dash which you can easily do with the universal dash kit.

First, chose the mounting holes in the dash kit that will be used to mount
the adapter into the factory hole. Then, mount the tweeter into the dash
adapter using the screw into the back of the tweeter. Now, run the wires up
into the dash and connect to the tweeter pig-tail wire and simply screw the
dash adapter down into the factory hole with the factory screws. Pop the
grille back over the location and you are done.

FLUSH MOUNT

This mount looks factory styled in nearly every vehicle if installed properly.
Although the opposite listener is slightly off-axis from the tweeter,
performance suffers very little due to the wide dispersion of the tweeter.

To make this installation, first choose a location ensuring no electrical or
mechanical interference behind the tweeter. Drill the proper sized hole in
the panel. Mount the tweeter into the cup using the screw provided.
Snake the wires into the door panels and properly locate the crossover
boxes for ease of connection and control access but ensure they are not
in direct access to water or other exterior elements. Finally, push the
tweeter through the hole, tighten the provided plastic nut onto the
threaded cup and you are done.

FLUSH-ANGLE MOUNT

This mount offers all the advantages of the flush mount above but it
angles the tweeter for better cross-car sound thus a better left/right
acoustical balance. It is slightly deeper than the flush mount due to this
configuration so care must be taken to ensure no impact on inner door
surfaces.

The mounting process is identical otherwise to the flush mount system
above so follow the directions in the flush mount system as stated.

Corporation, 2800 S. 25th Avenue, Broadview, IL 60153. (This is a simple to use IBM PC computer program used to

predict the frequency response of a subwoofer in 10 different enclosures including sealed, vented, and bandpass
configurations. Basic passive crossover designs are covered as well. It is provided free of charge as a download from
the Blaupunkt Internet site at: http://www.blaupunkt.com.)

MOUNTING SPEAKERS IN BOXES

Many people prefer to mount their component speakers into some sort of
enclosure in order to mimic that of a conventional home speaker system. We
support this concept because such an enclosure provides an acoustical “air
spring” for the woofer thus lowering distortion, increasing power handling, and
increasing the life of the speaker system. But, you must also supplement the
low frequency part of the music (below @ 100 Hz) with some kind of subwoofer
for an acoustically balanced audio system.

Although you can place your speakers into nearly any reasonable sized box,
the box technology dictates a sealed design because of inherent the “Thiele­Small” parameters of the woofers. The woofers in our systems all have Qts
values near 0.7 which allows for a sealed box or a semi-infinite baffle door
speaker installation only. Attempting to design and vent a woofer box in any
way will only raise distortion, lower power handling, and shorten speaker life
while providing little or no additional bass response. In other words...don’t
bother trying to make any unique vented box systems - they don’t benefit this
type of speaker.

Please refer to the adjacent table for
recommended dimensions of an enclosure
keeping size to a minimum yet providing
good acoustical response. This table
shows suggested exterior dimensions
needed to achieve the interior air volumes
yet compensating for 3/4 inch wood panels
and interior speaker air volume
displacements. Other panel dimensions can
be used (e.g., an equal length cubic box)
but this is not recommended since the
lengths given here help prevent internal
standing wave induced frequency response
problems.
