WARNING
• Always use the special red battery and ground |
wire |
the battery wire directly to the car battery positive |
terminal (+) and the ground wire to the car body. |
• Do not touch the amplifier with wet hands. |
Otherwise you may get an electric shock. Also, do |
not touch the amplifier when it is wet. |
• For traffic safety and to maintain safe driving |
conditions, keep the volume low enough so that |
you can still hear normal traffic sound. |
• Check the connections of the power supply and |
speakers if the fuse of the separately sold battery |
wire or the amplifier fuse blows. Detect the cause |
and solve the problem, then replace the fuse with |
another one of the same size and rating. |
• To prevent malfunction of the amplifier and |
speakers, the protective circuit will cut the power |
supply to the amplifier (sound will stop) when an |
abnormal condition occurs. In such a case, switch |
the power to the system OFF and check the |
connection of the power supply and speakers. |
Detect the cause and solve the problem. |
• Contact the dealer if you cannot detect the cause. |
• To prevent an electric shock or |
during connection and installation, be sure to |
disconnect the negative |
beforehand. |

4 Ohm Bridged Mode | 2 Ohm Bridged Mode |
Do NOT install or use your Pioneer ampli- fier by wiring speakers rated at 4 Ohm (or lower) in parallel to achieve a 2 Ohm (or lower) bridged mode (Diagram B). Amplifier damage, smoke, and overheating could result from improper bridging. The amplifier surface could also become hot to the touch and minor burns could result.
To properly install or use a bridged mode for a
Ωload, wire two 8 Ω speakers in parallel
with Left + and Right - (Diagram A) or use a single 4 Ω speaker. For a
