do your own installation please note the following important information.
Before cutting any trjm or steel make sure you clear all moving parts and factory electrical
lines.
Be sure to leave enough slack in the wire to prevent pulling or stretching wires for service
later.
Tie down all loose wires to prevent them from getting caught in moving parts or shorted due
to abrasion over time.
Never mount speakers in a car's wheel wells or areas where they might be subjected to
moisture or road spray.
Proper speaker polarity must be observed. The polarity positive side is marked by a (+)
sign or a red dot. At low frequencies woofers out-of-phase will acoustically cancel having
little bass output.
Although the components used in Blaupunkt speakers exceed most international standard,
speaker frames can be twisted by improper installation on uneven surfaces. This can occur
when the surface is heavily padded or carpeted and the screws-are unevenly or
over-tightened.
Speaker wire should be isolated from the electrical system of the car and routed away from
n
any factory systems to avoid noise picked up and fed back to the amplifiers.
Speaker wire size should be of sufficient size to carry the full power of the amplifier (16
n
gauge or larger sizes are quite adequate for most systems).
