Start Up and Adjustments
1. Please Note! When you turn on the C2K 9.0XD, the adjustment
LED’s will light up to display the last adjustment made,
regardless of the position of the selector switch. Therefore, when
making or verifying settings you must make a minor adjustment
to each setting so the microprocessor will set the LED’s to
display that particular setting.
2. If this amp is being moved from one car, or system, to another, please
perform the “reset” function (at # 4.) before proceeding further.
3. Initial start up procedure/check list:
• Make sure all installation guidelines have been followed.
• Configure amp for proper operation. (Crossover, stereo/mono,
etc.)
• Connect any peripherals to the system. (EQ’s, VFD’s,etc.)
• Make sure the 175-amp fuse is installed on the main 12 volt lead.
• Re-read all warning labels.
• Turn down the head unit volume.
• Turn on the system at 0 volume.
• Using the amps MODE button, switch to the VOLUME LED, turn
the ADJUST knob counter clockwise to assure that gain is at
minimum.
• Slowly turn up the volume at the head unit, paying close attention
to the sound of the speakers.
• Check for proper response from the speakers and volume level,
making sure that speakers don’t exceed their limit. (Bottom out)
• If speakers bottom out, go immediately to the “Pre-Clip” Level
adjustment section.
• If the speakers do not bottom out, and you want more volume, you
can now adjust the gain using the Volume Adjust procedure.
4. Pre-Clip Level setting: This is an extremely important safety setting, as
the pre-clip, when properly used will prevent the speakers from
exceeding their limits of travel.
• Set the amp VOLUME at minimum
• Push the MODE SELECT button until the Pre Clip LED lights.
• Turn the ADJUST knob counter clockwise until the ¼ LED lights
up.
• Bring deck volume level up to expected maximum(usually ¾),
while listening for any speaker problems or bottoming out.
