Conrad Electronic XCA 1000 Manuel D'utilisation page 33

For connecting the cinch inputs, use only shielded cinch cables
suitable for this purpose. The use of any other cable may cause
interference.
Keep the length of the connection cables as short as possible.
Do not install the cables in the proximity of other cables. Thus, you
avoid interface at the amplifier input.
To avoid distortion or mismatches that could lead to the power
amplifier being damaged, only sources with a cinch plug should be
connected to the cinch inputs and only speaker outputs should be
connected to the speaker inputs of the models XCA 1000 and XCA
1002. Please, also pay attention to the connection loads in the
"Technical Data".
Model XCA 1500 and XCA 2000
Connect the cinch outputs of your car
radio to the cinch connections IN (7) of
the amplifier.
