“BASS BOost” Control
The J2-250.1 includes a single band, boost- only bass equalizer controlled by a rotary knob marked “Bass Boost”. This control has a boost range of 0dB (full-counterclockwise) to +9dB (full-clockwise) and is centered at 45 Hz.
REMOTE LEVEL Control
The J2-250.1 includes a remote level control that can be mounted in the front of the vehicle. This control allows the owner to adjust the overall subwoofer level to taste. To connect the remote bass control knob, insert its plug into the jack labeled “Remote Level Port” on the amplifier and route the cable and control to the desired location in the front of the vehicle.
Care should be taken to securely mount this control in a manner that does not interfere with vehicle operation.
When setting the amplifier’s input sensitivity, the Remote Level Control should be unplugged or at full clockwise rotation (maximum level).
