Remember to always disconnect battery ground before working on a vehicle's
electrical system
• First, the +12V(BATT) terminal is connected directly to the battery of your car. Use a cable
of at least 5 mm2 (16 AWG), and make sure that the connectors are of the same value.

• Second, the ground terminal (GND) must be fastened securely to the chassis of the
vehicle with the same gauge cable as the positive cable (the same amount of power has
to run through it). Ensure that all paint, undercoating or any other insulation is removed
from the area where you want to make your ground connection to.
• Third, the last cable to connect is your remote turn-on (ON or REM). Many radio-cassette
and CD-players have an output terminal for connection of the Remote turn on of a
amplifier. If you don't have such an output, a separate switch must be installed to control
your amplifiers ON/OFF function.

The next to connect is your signal input. Use either the Line input or the High Power input (if
your head-unit does not have a Line output). Pay attention which polarity and which channel
(left or right) you are connecting. Always connect the + to a +, and the – to a -.
Never use the Line input and the HIGH Power input at the same time. Serious damage
to your Car or Audio system can be the result
Once you have connected your power and signal input, it is time to adjust the crossover and
input level for the expert tuning to get your own personal sound.
aDjusting thE activE variablE crossovEr:
To get your personal sound, you can adjust the built-in active variable crossover from 40Hz
to 250Hz at 12dB per Octave. Allthough the perfect adjustment varies with every piece of
music, a general adjustment for the kind of music you listen to, can be archiefed. So don't
hesitate to play around with this crossover.
aDjusting thE lEvEl input:
1. Set your level adjustment at the minimum sensitivity.
2. A djust the volume control of your head unit (Radio/ cassette or CD-player) to approximately
3/4 volume.
3. T urn your level adjustment clockwise until you hear the amplifier begin to distort. The
amplifier of a BCT Tube "clips" very softly, so this can sometimes be a difficult adjustment.
