When you are using coaxial or component speaker system, this allows you to adjust high-pass X-over fre-
quency from 15Hz to 250Hz. To get better sound quality from coaxial or component speaker system, we 
recommend the frequency should be higher than 15Hz.

Using this volume, adjust the LPF frequency for your subwoofer speaker(s) operation.

Your PowerBass Xtreme amp includes a remote GAIN control module. It uses standard 6-pin telephone wire 
and modular (U.S.A. style) telephone connectors.  To connect the remote GAIN Control to the amplifier, simply 
insert one end of the telephone plug into the REMOTE gain input port.  Plug the other end into the remote 
module.  Install the module within easy reach on or under your dash.

NOTE: The GAIN control on the side panel of the amplifier chassis serves as the “main” GAIN 
control, and the remote will not exceed the setting of the end panel.
