Important information regarding class D amplifiers: Class D power amplifiers can sometimes, due to their design, interfere with radio reception. To avoid this, please note the following points:

• Only connect speaker cables with a narrow twist.
• The ground cable from the amplifier to the body should be as short as possible.
• Do not lay power and speaker cables near radio reception elements.
• The amplifier should be mounted as far as possible from the radio reception elements.
• Use only pure copper wires.
