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 advan-
tage 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.
SYSTEM CONFIGURATION #4
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 compli-
cate the system or take up more room. Such a system WILL NOT equal the performance of a subwoofer sys-
tem 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.
