The fan and ventilation openings are responsible for cooling the amplifier when it is in
use, so it cannot be obstructed.
CAUTION
Before making any connections to the power terminals, make sure that the negative (-)
of the vehicle battery is disconnected.
CAUTION
3 - POSITIVE POWER SUPPLY:
Use cable of minimum 2/0 AWG direct from the positive battery pole, with fuse
or circuit breaker (230A), as close to it as possible.
In case of power bus bar using, avoid tightening with extenders on the allen wrench, as excessive torque may
break the the terminal.
2 - NEGATIVE POWER SUPPLY:
Use cable of minimum 2/0 AWG as short as possible, connected to the negative
battery pole.
1 - SMART COOLER:
This amplifier has two internal ventilation fans. For perfect functioning, the amplifier must
be installed in a cool and aired place with at least 1” (25mm) space around the heasink for proper heat spreading.
The usually working temperature of amplifier is 65°C.
In order for your amplifier to have the best performance, it is necessary to use all the power inputs. See example
on the next page. We recommend that all cables have tinned ends for better electrical contact.

The thermal protection waits for cooling before restarting.
If it goes into protection, the amplifier will automatically restart.
