Testing
Before you finish the installation, you should do the
following tests to make sure the wiring is correct and
everything is operating properly.
Reconnect Battery
When wiring is complete,
reconnect the battery
negative terminal.
Test speaker connections
Make sure the speakers are connected right. Use
the balance control on the head unit to make sure
right channel is on right speaker etc. If speakers
don´t play at all, one or both speaker wires may
be disconnected.
Test power wiring
1. Turn on the head unit but do not turn up the
volume. The amplifier power light should
come on. If not, check the remote and +12
volt wires. Also check the ground
connection.
2. Turn up the head units volume slightly. All
speakers should operate. if not, check wiring
connections at amplifier and speakers.

With the HPF-filter in OFF
position the amplifier allows
the speakers to play
fullrange. If you for some
reason want to limit the low
bass reproduction switch on
the HPF-filter. The typical
setting is then around 60 –
80 Hz.
The subsonic filter takes away
the very deepest frequencies.
Turn on the subsonic filter if you
want to remove these
frequencies.
The LPF will allow low
frequencies only and blocks
higher frequencies. A typical set-
ting is 70 – 100 Hz.
