SUB EQ
0 + 6
dB
One 4 ohm or 2 ohm subwoofer
PHASE switch:
The phase can be adjusted in either
0 or 180 degrees. This is used to get
the best possible ”front stage” from
the subwoofer.
SUB EQ
is used to increase the bass
volume at a low frequency.You can
select the amplification between 0 dB
( no amplification ) and +6 dB ( full
amplification ) at
40 Hz center
frequency
This function is used to compensate
for the bass box function and to adjust
for your own taste of bass. Set level
control at 0 dB if you want it to be
inoperative.
Two 4 ohm subwoofers
NOTE!
Minimum amplifier load is 2 ohm, lower
impedances may damage the amplifier. This
connection gives a 2 ohm load with two 4 ohm
subwoofers.

NOTE!
Minimum amplifier load is two (2) ohm. You can
connect two 4 ohm subwoofers or a single 2 ohm
subwoofer to the amplifier.
For power wiring, see page 4
For high or low level input wiring, see page 5
The low pass filter is
mostly used for
subwoofers. It will allow
low frequencies only and
blocks higher frequencies.
A typical setting is 50 –
70 Hz.
You can also choose fil-
ter slope, 12 dB or 24 dB.
Choose the setting that
sounds best in your car.
NOTE!
The speaker terminal
has dual + and - for
easier connection if you
have more than one
subwoofer. They are
internally connected in
parallel and
can not be
bridged.

The
Subsonic filter
blocks
the very deepest
frequencies from reaching
the subwoofers. It can be
set from 15 to 150 Hz and
can be switched on / off.
