2 Channel Full-range -or- High-Pass Mode
This installation is most popular for listeners who want to simply
increase the power to the rear speakers in a car. The resulting
performance is most commonly a louder overall sound field from the rear.
But, such a system’s biggest benefit is the additional bass response since the bass control of the radio can be turned up
without distorting the amplifier. Such a system is not necessarily louder in the mids and highs but is able to play louder in
the low frequencies due to this additional power. This leads to an overall richer and stronger sound experience for the
listener without additional subwoofer boxes or electronics that may complicate the system or take up more room. Such a
system WILL NOT equal the performance of a subwoofer system but will certainly be a pleasant improvement.
With the addition of a high-pass filter, this amplifier is set up to complement a dedicated subwoofer amplifier/speaker
system. This allows for smaller (e.g., 5" or 6") satellite speakers to operate most efficiently without being over-driven in the
bass region where a dedicated subwoofer system operates most efficiently.

3 Channel Multi-Mode (Passive)
The multi-mode system is a “poor-man’s” satellite/subwoofer
system. This amplifier is able to drive speakers in stereo mode
and at the same time drive low frequencies to a dedicated
subwoofer speaker. By inserting inductors (coils) and capacitors,
the result is an inexpensive solution to generating a ‘3' channel
system with a 2 channel amplifier.
Using passive components (coils and capacitors) the installation is
simple and performs adequately for most listeners. Such a
system will not perform as well as an “active” system because the slow attenuation (roll-off) of the frequency response
resulting in a moderate amount of over-lapping of the sound spectrum between the satellites and subwoofers. It is
important to remember that although surprisingly pleasant performance is achieved, this is a compromise system and will
NOT perform as well as a dedicated 3 channel system with electronic crossovers.
