THANK YOU FOR CHOOSING BLAUPUNKT!
Congratulations! You are the now the owner of an exceptional car audio amplifier from the audio enthusiasts at
Blaupunkt. Our engineering staff has spent considerable time refining our PCA series amplifiers in order to introduce great
sound to the consumer at an affordable price. With these products we focus on sonic performance but balanced with
rugged design and flexible installation.
Not only do we offer you a great product but also a supportive owners manual. This manual can be used as a teaching
guide due to its brief, but informative, explanations of amplifier and system design. We are also very concerned about the
end consumer using proper installation techniques for the highest performance possible from their new audio products.
MOST important to us are the 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.
PCA AMPLIFIER BENEFITS & FEATURES
There is a constant push for entry level amps to “play with the big dogs” yet for a low
price point. Rarely are they able to do so…. until now.
Rock solid Class AB designs ensure “in your face” sound with little fear
for reliability or performance. The rugged designs of the PCA
amp line, and their remarkable input frequency and gain
setting flexibility, enable nearly any system
configuration. Fat power and speaker leads make
sure all that power going in comes out the best
sound possible.
Should something go wrong in the installation, have
no fear. Protection for output short circuits and short
to grounds or 12 volts are all covered and a safety
“Protect” light lets you know. Peace of mind, and big
power, at low price points…look no further.
• Real, RMS watts. No need for “bogus” watts. This is the
real stuff in a great amp so there is no need to exaggerate - it
does what it says.
• Reinforced Class AB designs with reinforced output stages
ensure solid performance and reliability.
• Big heat sinks to ensure adequate heat dissipation regardless
of the load (they look cool too).
• Monster size, gold plated power and speaker
terminals for reliable, low resistance connections.
• Protection LED for notification should the unit shut
down due to installation problems.
• Wide range input voltages of 0.3-6.0Vrms.
• Continuously variable crossover frequency settings.
• 2 ohm output stable (unbridged mode)

SAFETY CONCERNS
We always recommend you have your Blaupunkt amplifiers 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 audio components away from nearby hot 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 - these amplifiers, used with high
efficiency speakers from ANY manufacturer, have the potential to cause permanent hearing loss after listening at
maximum volume levels for several hours.
INSTALLATION WARNINGS!
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
amplifier 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 amplifier 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 CAREFUL 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!

SYSTEM PLANNING
Before wiring up an audio system that may not achieve the
sound quality you want, be sure to choose a system concept
that fits your listening requirements. Basic systems, a
receiver with internal 4x20 watts and 4 coax speakers, are
adequate for many listeners. But, when you want to really
“feel” the music, you will need some kind of subwoofer
amplifier/speaker combination. Although many people might
jump into an “add-on” amplifier to power to rear coaxial
speakers, a better choice is usually a subwoofer
amp/speaker system that supplements the existing 4
speaker system as shown in the adjacent drawing. Such a
system provides a surprising improvement in sound quality
due to the usually dramatic increase in bass response.

Full-Range
The next dramatic step up in performance is with a “multi-
channel” system that offers more dynamic range in the mids
and highs due to higher power plus more bass response due
to multiple woofers and/or more power. But, with such a
system, the stereo image and overall listening experience
usually becomes much more life-like due to better tonal
quality midrange/tweeter speakers and usually better
placement.

Sat Amplifier
(4x60 W)
To build such a system though, complexity goes up due to
the addition of passive or active crossovers which take time
to install and may inject noise into the system due to
potential noise signal pick up. The results though of such a
system can be dramatically pleasing.

INSTALLATION TOOLS
For most installations, simple hand tools are adequate to install an aftermarket amplifier. Depending upon the
mounting locations 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

Most vehicles built since 1990 have adequate current
capability for your amplifier. Except for systems above
about 500 W rms, the factory charging system and battery
should easily support it if properly installed. Proper wire
size must be chosen to ensure adequate current delivery to
the amp. Wire size (gauge) of the cables need to increase
in size for higher power systems. (Wire sizes larger than
those noted are usually a waste of time and money since
they offer Little or no performance improvements.)

Current requirements for an upgraded audio system dictate a
dedicated power line be run from the amplifier directly to the
battery of the vehicle. This line should NOT be run to the
fuse panel of the vehicle but directly to the battery. DO NOT
run to the alternator either. There MUST be a fuse installed
at the battery with adequate amperage as shown in the chart
above.

POWER CONNECTIONS & TRIGGER LINE:
Power Terminal (+12V)
Connect directly to the vehicle battery (+)
terminal with 10 gage wire (minimum)
SPEAKER OUTPUTS - The amplifier is connected to appropriate impedance
speakers via these leads. It is IMPERATIVE that these leads NOT be
connected or touch the vehicle chassis in any way or the amplifier will be
damaged. The (+) and (-) leads of the amp are in no way inter-connected to
one another. Also, NONE of the leads can touch each other, touch ground, or
touch +12V or damage may occur to the amp or vehicle.
GROUND - This is the high current ground connection to the chassis of the
car. It should be fastened to a clean ground connection in the vehicle,
capable of handling high current loads. This wire should be no longer than 3
feet (1 meter)
+12v - A high current line run direct from the batter is highly recommended to
insure adequate current and voltage. This line MUST be run through a
dedicated fuse of some kind and this fuse should be located immediately
next to the power source. This in-line fuse is used to protect the vehicle
should a short to chassis occur.
TRIGGER - This line tells the amp to turn on and is remotely switched from
the radio which normally provides an amp “trigger” output. This line is
required to go “high” (+12V) to turn on the amp. If this line is not available,
use the power antenna line trigger which is normally available in most radios.

are being required from the amp beyond its design limits. Although another
fuse should be installed inline with the high power line at the battery, this
amplifier mounted fuse MUST remain in the circuit to protect the amplifier.

LINE LEVEL INPUTS & OUTPUTS - The most commonly used inputs & outputs in the aftermarket are RCA type line level
inputs. These can handle up to about 6 Volts rms without overdriving the amplifier. Such high voltages are rarely found
from car audio head units so this is a very comfortable value. But, should the use need to drive the amp directly from
speaker level leads, use the supplied “High Level Adapter” to connect to the amp.
BASS BOOST - This control provides additional bass in the 45Hz area to give a stronger low end “feel” to the bass. Once
switched on, this will also allow the amp to be driven into distortion sooner so the user must be aware.
HIGH-PASS CROSSOVER CONTROL - If the control is in the “HP” position the amplifier passes only mid and high frequency
sound. The lower limit for such sound is set via this control. A common setting is just above 100Hz.
LOW-PASS CROSSOVER CONTROL - If the control is in the “LP” position the amplifier passes only low frequency sound. The
upper limit for such sound is set via this control. For bass, a value just below 100Hz is usually best.
GAIN CONTROL - The gain control allows for a range of 0.3-6Volts input. This means that if the setting is a 0.3V, it only takes
0.3Volts to drive the amp to full output. (Such a low setting allows for the amp to be easily overdriven and more
susceptible to noise so a mid-position is highly recommended for most radios.)
CROSSOVER MODE SELECTOR - Depending upon the system design chosen, you need to set the amplifier in the proper
“mode” be it LP, Flat, or HP. The low-pass and high-pass frequency settings are explained above. The “Flat” setting
simply allows for the amp to pass all audio frequencies without any kind of crossover filter application. (This is common
with 6x9” fullrange coaxial speakers for example.)
PROTECTION LED - This light turns on if the amplifier senses a severe problem, such as a speaker short circuit.
POWER ON LED - This light will turn on when the amplifier receives a +12V turn on signal from the radio. If the amp is
properly wired, but the light does not turn on, there may be a short circuit condition that the amp is protecting itself from.

1 Channel Bridged Subwoofer Mode
By electrically connecting a subwoofer speaker in the way shown
above, you are able to greatly increase the output power delivered
from the amplifier to the speaker. Such a circuit increases the
voltage “swing” across the speaker which increase the power seen
by a factor of 2 to 4 times that in stereo mode.
This is a very logical set-up for systems that are space limited to
allow for only one subwoofer in a vehicle. The number and box
4Ω (main)
volumes are compensated by simply more amplifier power pushing a single speaker.
Such a configuration is also a surprisingly good performer. These increases in power are always welcome but you must
take care to avoid low impedances (below 4 ohms) since most amplifiers will overheat and shut down if over-driven into
such a configuration. You must also take care that you are not exceeding the thermal, or excursion, power limiting values
for the woofer. Surprisingly high power levels can be achieved with such a system without realizing it thus quickly
damaging the woofer.

2 Channel Dual Subwoofer Mode
The largest improvement in sound quality always comes when
adding some kind of subwoofer via a dedicated subwoofer
amplifier and electronics crossover. The electronic crossover
ensures minimal overlap of the bass response with the mid and high frequencies from the other speakers resulting in a
more accurate performance compared to conventional coaxials with additional power.
By installing this amplifier in the stereo mode, you are able to drive two subwoofer speakers and in to low impedance loads
(e.g., 2 ohms) without over heating the amplifiers. Also, such an installation more easily supports a standard 2 speaker
woofer box that may already be constructed. Since two woofers can play 6 decibels louder than one at a given power
(due to acoustical laws of “mutual-coupling”), the resulting sound pressure level is substantial. This is probably the most
common use for a conventional two channel amplifier there is.

2 Channel Full-range -or- High-Pass Mode
This installation is most popular for listeners who want to simply
increase the power to the rear speakers in a car. The resulting
performance is most commonly a louder overall sound field from the rear.
But, such a system’s biggest benefit is the additional bass response since the bass control of the radio can be turned up
without distorting the amplifier. Such a system is not necessarily louder in the mids and highs but is able to play louder in
the low frequencies due to this additional power. This leads to an overall richer and stronger sound experience for the
listener without additional subwoofer boxes or electronics that may complicate the system or take up more room. Such a
system WILL NOT equal the performance of a subwoofer system but will certainly be a pleasant improvement.
With the addition of a high-pass filter, this amplifier is set up to complement a dedicated subwoofer amplifier/speaker
system. This allows for smaller (e.g., 5" or 6") satellite speakers to operate most efficiently without being over-driven in the
bass region where a dedicated subwoofer system operates most efficiently.

3 Channel Multi-Mode (Passive)
The multi-mode system is a “poor-man’s” satellite/subwoofer
system. This amplifier is able to drive speakers in stereo mode
and at the same time drive low frequencies to a dedicated
subwoofer speaker. By inserting inductors (coils) and capacitors,
the result is an inexpensive solution to generating a ‘3' channel
system with a 2 channel amplifier.
Using passive components (coils and capacitors) the installation is
simple and performs adequately for most listeners. Such a
system will not perform as well as an “active” system because the slow attenuation (roll-off) of the frequency response
resulting in a moderate amount of over-lapping of the sound spectrum between the satellites and subwoofers. It is
important to remember that although surprisingly pleasant performance is achieved, this is a compromise system and will
NOT perform as well as a dedicated 3 channel system with electronic crossovers.

TROUBLE-SHOOTING GUIDE
Below is a basic trouble-shooting guide to assist in seeking out and correcting a problem that may occur in the installation
process. Although lengthy, this chart cannot address every single problem possible but mainly the ones most common.
SYMPTOM
PROBABLE CAUSE OR CORRECTION
■
No power (power light not on)
Check connections to amps +12 volt, ground, and remote lines.
■
Use voltmeter to verify voltages are at terminals of amp.
■
Check main power connection at battery.
Check fuse in power line at battery.
Disconnect all speakers but not power lines - if unit then turns on, a speaker short
or speaker line touching vehicle chassis is likely.
■
■
■
Power but no sound (power light is on)
No sound from one channel or entire side
Very low sound level
Check all input cable lines for connection.
■
Disconnect speakers from amp, test speaker lines with digital voltmeter to verify >2
ohms per channel (non-bridged mode).
■
Check radio’s balance and fader control positions - verify they are at center.
Check speaker connections at amp and speaker.
Check input leads for connection to amp.
■
■
■
Verify radio balance and fader controls are at center positions.
■
Check amplifier’s input gain control setting - adjust for higher output levels if
necessary (gain settings closer to 0.3 volts).
■
Receiver may have very low output voltage levels - a step up “line driver” may
have to be used.
■
Power amplifier turns on and off
repeatedly (motor-boating sound)
Make sure power connections at batter are tight.
■
Verify battery voltage is >11.5 volts DC (12.5-15V engine on) at amplifier with engine off.
■
Check all radio and amplifier ground connections.
■
Amplifier turns off during loud or distorted
passages
Input stage being over-driven - lower input gain (closer to 4 volt setting).
■
Verify battery voltage is >11.5 volts DC at amplifier with engine off.
■
Check all radio and amplifier ground connections.
Verify speaker loads >2 ohms on all channels (non-bridged mode).
■
■
Amplifier performs fine but gets very hot
to the touch
Input gain control too high - lower accordingly (closer to 4.0 volt setting).
■
Verify speaker loads >2 ohms on all channels (non-bridged mode).
■
Verify the mounting location allows for free air movement around the amp.
Preferably, the amp should be mounted with fins up and down so rising heat moves
quickly away from amp.
■
Amplifier turn-on/turn-off pops or noises
“turn on race” - disconnect trigger from radio and turn on/off via a wire jumper to
power terminal. If noise goes away, the radio is turning on/off too slowly. This is
radio problem and can only be corrected with outboard turn-on delay relay system.
Radio “thump” - disconnect the RCA input lines to the amp and turn on/off via radio
■
trigger. If noise goes away without RCA lines connected, the radio is sending pops
out through RCA lines. This is a radio problem and can only be corrected with
outboard turn-on delay relay system.
■
Cracking noises on AM/FM radio but not
on tape or cd.
Ensure the problem is “radiated noise” by placing a portable FM radio near the car
engine. If noise is picked up, then it is a vehicle problem and not your system.
Research to isolate the source and properly shield or bypass.
■
Are spark plugs and wires > 3 years old? These can often radiate substantial noise
when old.
■
Verify the engine block has a good ground connection to chassis ground.
■
Verify the engine compartment hood is grounded to vehicle chassis via a braided
grounding strap.
■
Whining noise, engine running, varies in
pitch or loudness with engine speed,
AND varies with radio volume control
setting (this is generally a RADIO
installation problem)
Verify all power and ground connections are clean at radio.
■
Re-route radio power and ground so they are sourced from same connections back
at amplifier (this is called a “common” ground).
■
Check all ground connections to ensure clean surfaces that have all paint removed
and also not oxidation buildup over time.
■
Verify there is some kind of power filtering choke assembly at back of radio. If not,
install one.
■
Whining noise, engine running, varies in
pitch or loudness with engine speed,
BUT, DOES NOT vary with radio volume
control setting (this is generally an
amplifier installation problem)
Check battery ground connections at chassis are clean and tight, scraped free of
oxidation, paint, and grease.
■
Re-route radio power and ground so they are sourced from same connections back
at amplifier (this is called a “common” ground).
■
Bypass all equipment between radio and amp (e.g., equalizers) directly connecting
radio. If noise goes away, signal processor has problem.
■
Check for signal level “ground loops” - disconnect the outer shield of the RCA cable
at one end of the cable (e.g., radio end). If noise goes away, modify cables
accordingly. There are voltage differences at the ground connections of the
components and these are NOT correctable any other way than such shield cutting
or an outboard “ground loop isolator” which is a small transformer.
