4 - NEGATIVE POWER SUPPLY:
Use a cable of minimum 4 AWG up to maximum of 1/0 AWG as short as possible,
connected to the negative battery pole.
1 - SMART COOLER:
This amplifier has two internal ventilation coolers, which cannot be obstructed. Controlled
by an intelligent system (Smart Cooler), it only operates at full speed when needed, ensuring longer cooler life
and a quieter operation of your amplifier. For a perfect operation, the amplifier must be installed in a dry and airy
place. We recommend not embedding it, in order to ensure adequate ventilation.
2 - POSITIVE POWER SUPPLY:
Use a minimum 4 AWG up to maximum of 1/0 AWG cable direct from the
positive battery terminal, with fuse or circuit breaker (150A), as close to it as possible.
3 - TERMINAL REMOTE:
It must be connected to the remote output of the head unit using a 18 AWG cable.
In case of power bus bar using, avoid tightening with extenders on the allen wrench, as excessive torque may
break the the terminal.
We recommend that all cables have tinned ends for better electrical contact.
