INSTALLATION
Control Setup and Adjustment
Input Signal Connections
Low level (RCA) input signal is preferred for best
Low Level (RCA) performance. Typical trunk-mount installations
require a 17-20 foot RCA cable. Most trucks and
behind-seat applications require a 6-12 foot RCA
cable. Using twisted pair construction RCA cables
will minimize noise.
Crossover Frequency
The adjustable crossover is used to filter out
Control frequencies above 25Hz ~ 120Hz. Adjust it to where
the BAK1500 sound output blends with the rest of
the sound system.
Phase Control The phase control compensates for delay between
the BAK1500 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 necessary. If the sound is thin or
lacking bass, adjust the phase control until the bass
is full and punchy.
Input Level Control
The input level control (LEVEL) is used to obtain the
best possible match between the head unit audio
output and the amplifier 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.
LED Indicator The LED indicator illuminates green during normal
operation.
