CONTROLS AND SETUP
POWER MODE
(AUTO MODE)
Set the switch to AUTO MODE is your system setup
doesn’t have a remote wire, as with stock head units.
The subwoofer will turn on automatically when it
detects an incoming signal (this feature only avail-
able on the B8-PT).
POWER MODE
(REMOTE WIRE)
Set the switch to REMOTE WIRE i
f
you have attached a
remote turn-on lead to the subwoofer.
LEVEL
The LEVEL control (gain) is used to obtain the best
possible match between the head unit audio output and
the amplier input. Begin by turning the input level
control fully counterclockwise. Next, turn up the
head unit volume control around 3/4 of the way up.
Adjust the input level control clockwise until audible
distortion is heard, then slightly counterclockwise to
provide the best match.
BASS EQ
The BASS EQ lets you boost or attenuate the bass level
to match your listening preference. Set the Bass EQ
at 0dB to start, and increase the level for stronger
bass.
PHASE
The PHASE control compensates for delay between the
subwoofer’s output and the rest of the sound system.
Begin with the phase control set to 0 degrees. If the
sound is adequate from the normal listening position
inside the vehicle, no further adjustment is neces-
sary. If the sound is thin or lacking bass, adjust the
phase control until the bass is full and punchy.
FREQ
The FREQ is an adjustable crossover will lter out
frequencies the frequency it’s set for. Adjust it to
where the sub’s sound output blends with the rest of
the sound system.
POWER
The POWER LED indicator illuminates red during normal
operation.
