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.

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.

Sub Amplifier (2x120 W)  
Subwoofers  
High performance multi-channel system  
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

POWER WIRING  
SYSTEM POWER AND GROUND WIRE CHART  
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.)

wire diameter must also increase. The wire sizes noted  
allow for a maximum 0.5 volts DC drop over the give wire  
run which results in Sound Pressure Level drops inaudible  
to the average listener.

FINAL VEHICLE WIRING  
Battery  
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.

FUSE - These fuses are only for catastrophic situations should the amplifier begin  
to self-destruct or incur installation situations where gross amounts of current  
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, these  
amplifier mounted fuses 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.  
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 below. 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.)  
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.  
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.  
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.

SYSTEM CONFIGURATION #1

High-Pass  
Subwoofer  
5 Channel Combo (2ch HP + 3ch passive Multi-Mode)  
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 ‘5' channel system with a 4 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 5 channel system with electronic crossovers.  
SYSTEM CONFIGURATION #2

Full-Range  
Full-Range  
Full-Range  
4 Channel (Full-Range,HP)  
For many listeners, they need only slightly higher system loudness and/or music dynamic range without the amplifier  
going into distortion. By simply adding additional power to the speakers this can be achieved in many installations.  
BUT, the speakers must be able to handle this additional power without damage.  
Such installations are most common with listeners who only need systems that can play moderately loud. Also, this  
consumer is often a person who simply cannot, or will not, accept additional amplifiers or speakers in the vehicle. Such  
systems will not be able to perform as well as audio systems with additional speakers and amps, but this is often an  
accepted trade-off for this consumers.

3 Channel Combo (2ch HP + 1ch Subwoofer)  
Like the four channel systems as shown above, the benefits, and performance trade-offs are similar. But, this system  
configuration offers an additional advantage with the internal high-pass crossover.  
This crossover reduces the bass to the front speakers thus protecting them under heavy low frequency loads. A typical  
system with larger drivers in the back is then able to be pushed harder without worry over the power handling on the  
front speakers.

2 Channel (Full-Range, HP, LP)  
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 improve-  
ment.  
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.

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.
