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!

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.
