example where the heater will blow over them. If |
the insulation heats up, it may become damaged, |
resulting in a |

•With high output the signal waveform is distorted, if you raise the gain of the amplifier the power changes only slightly.
•If you decrease the volume of the head unit and set the gain control of the amplifier to the proper position but still the sound cuts out from time to time, contact the nearest authorized PIONEER Service Station.
• Never replace the fuse with one of greater value |
or rating than the original fuse. Use of an improp- |
er fuse could result in overheating and smoke and |
could cause damage to the product and injury |
including burns. |

Speaker Wires” section. Amplifier damage, |
smoke, and overheating could result from a non- |
specified connection. The amplifier surface could |
also become hot to the touch and minor burns |
could result. |
• Connect either of two subwoofers to the amplifier; |
1: a subwoofer with a 350 W or larger nominal |
input and an impedance 4 Ω, or 2: a subwoofer |
with a 600 W or larger nominal input and an |
impedance 2 Ω. If the nominal input and imped- |
ance are out of the above ranges, the subwoofer |
may catch fire, emit smoke or become damaged. |
• Install and route the separately sold battery wire |
as far away as possible from the speaker wires. |
Install and route the separately sold battery wire, |

far away as possible from the antenna, antenna |
