ELECTRICAL CONNECTIONS
Make sure to disconnect the battery’s negative terminal.
• Be sure to ground this unit to the car’s chassis again after installation.
Note:
It is recommended to connect to the speakers with maximum power of more than 50 W (both at the rear and at the front, with an impedance
of 4 Ω to 8 Ω). If the maximum power is less than 50 W, change “AMP GAIN” setting to prevent the speakers from being damaged (see
page 13 of the INSTRUCTIONS).
