• 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 (seeHeat sink page 13 of the INSTRUCTIONS).
