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.

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!
