The amplifier power cable must be fitted with a fuse no more than 30 cm from the battery to protect the vehicle battery in case of a short circuit between power amplifier and battery. The fuse of the amplifier protects only the amplifier, not the vehicle battery.
Use loudspeakers with 2 - 4 Ω 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.

Audio inputs (see Fig. 3)
You can select between 2 different audio inputs;
–Cinch (RCA)
–Hi level (loudspeaker connections)
Use only one of the audio inputs; otherwise, it may lead to audio interferences.
The preamplifier outputs are connected to the cinch (RCA) sockets 1via a shielded sound cable.
With control via the loudspeaker outputs, the input connec- tions of pos. 2/3are fed to the closest loudspeaker cables (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.
