[. . . ] The power supply must be connected to the wires via the fuse. If the power is not turned ON (or it is ON, but will be OFF immediately), the speaker wire may have a short-circuit or touched the chasis of the vehicle and the protection function may have been activated. Therefore, the speaker wire should be checked. If your car's ignition does not have an ACC position, connect the ignition wires to a power source that can be turned on and off with the ignition key. [. . . ] If your car's ignition does not have an ACC position, connect the ignition wires to a power source that can be turned on and off with the ignition key. If you connect the ignition wire to a power source with a constant voltage supply, as with battery wires, the battery may die. If the console has a lid, make sure to install the unit so that the faceplate will not hit the lid when closing and opening. If the fuse blows, first make sure the wires aren't touching to cause a short circuit, then replace the old fuse with one with the same rating. Insulate unconnected wires with vinyl tape or other similar material. To prevent a short circuit, do not remove the caps on the ends of the unconnected wires or the terminals. The unit may be damaged or fail to work if you share the - wires or ground them to any metal part in the car. When only two speakers are being connected to the system, connect the connectors either to both the front output terminals or to both the rear output terminals (do not mix front and rear). For example, if you connect the + connector of the left speaker to a front output terminal, do not connect the connector to a rear output terminal. After the unit is installed, check whether the brake lamps, blinkers, wipers, etc. If the unit is unstable, it may malfunction (eg, the sound may skip). Engage the catch pins on the removal tool 3 and remove the two locks on the lower level. Lower the frame and pull it forward as shown in the figure. When the lower level is removed, remove the upper two locations. The frame can be removed from the top side in the same manner. Remove the Hex-head screw with integral washer (M4 × 8) on the back panel. Insert the two removal tools 3 deeply into the slots on each side, as shown. Lower the removal tool toward the bottom, and pull out the unit halfway while pressing towards the inside. Be careful to avoid injury from the catch pins on the removal tool. Pull the unit all the way out with your hands, being careful not to drop it. [. . . ] Lower the removal tool toward the bottom, and pull out the unit halfway while pressing towards the inside.
