WIRING CONFIGURATIONS

The

MaxxBass

Processor is recommended in two different

configurations.

1. Front Stereo Configuration
The figure below illustrates the wiring for a front stereo
configuration. One

MaxxBass

Processor is used between the front

channel source and front speaker amplifier to increase the bass
response only on the front speakers.

Implementing

MaxxBass

on the front speakers will increase the

perceived bass response of these speakers down to 30-40Hz
providing a Virtual Subwoofer. The listener will achieve better bass
balance and imaging with a rear mounted subwoofer or trunk
mounted speakers with sufficient bass response.
