3 Channel Combo (2ch HP + 1ch Subwoofer)
Like the four channel systems as shown above, the benefits, and performance trade-offs are similar. But, this system
configuration offers an additional advantage with the internal high-pass crossover.
This crossover reduces the bass to the front speakers thus protecting them under heavy low frequency loads. A typical
system with larger drivers in the back is then able to be pushed harder without worry over the power handling on the front
speakers.

2 Channel (Full-Range, HP, LP)
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.
