Warranty

within the European Union. For devices purchased outside

the European Union, the warranty terms issued by our re-

spective responsible domestic agency are valid. The warranty

terms can be called up from www.blaupunkt.com.

Recommendation

The performance of an ampli er can only be as good as its in-

stallation. A correct installation increases the overall perform-

ance of your car sound system. The EMA ampli er should be

installed by a trained person. If you would to install it yourself,

please read these installation instructions very carefully and

allow yourself su cient time for the installation.

In conclusion, allow us a few words about the topic of health

protection:

During the playback of music in your vehicle, please consider

that continuous sound-pressure levels above 100 dB can

lead to permanent damages to the human ear and even to

loss of hearing. Using today's high-performance systems

and loudspeaker con gurations allows for reaching sound-

pressure levels above 130 dB.

Safety notes

Please observe the following safety notes during the instal-

lation and connection.

Disconnect the negative pole of the battery! Observe the

safety notes of the vehicle manufacturer.

When you drill holes, ensure that you do not damage any

vehicle components.

The cross section of the plus and minus cable may not

be less than 6 mm

Use cable glands for holes with sharp edges.

An incorrect installation can result in malfunctions of the

electronic vehicle systems or your car sound system.

Installation and connection instructions

With respect to accident safety, the EMA 455 must be secured

in a professional way.

When selecting the installation location, select a dry loca-

tion that offers sufficient air circulation for cooling the

ampli er.

The EMA 455 must not be installed on rear shelves, rear seats

or other locations that are open to the front.

The installation location must be suitable to accept the ac-

companying screws and provide a  rm support.

–

The ampli er power cable must be  tted with a fuse no more

than 30 cm from the battery to protect the vehicle battery in

case of a short circuit between power ampli er and battery.

The fuse of the ampli er protects only the ampli er, not the

vehicle battery.

Use loudspeakers with 2 - 4  impedance (see table or in-

stallation drawing). Observe the maximum power handling

capacity (music output). Do not connect loudspeakers to

earth, use only the referenced terminals.

(front or rear) on the left and right. They are separated and

connected to the input connections. The polarity of the + or -

connections must be observed. Bridge output stages (BTL) can

also be connected directly without an additional adapter.
