MB1 MEGA BASS Digital Synthesizer needs to be installed in the signal path
as close as possible to the source unit (between a head unit and an external
amplifier), before any crossover circuit. Although the MB1 is close to the source
unit’s signal, it is usually mounted in the rear of the vehicle, as close as possible
to the amplifiers.
If you are using an equalizer, connect the MB1 to the SUB OUT of the
equalizer and use it to drive the bass amplifier, as shown below.
