Run Cables
Properly route power, speaker, and RCA cables through the vehicle. -
Mount Amplifier
Choose a mounting location for the amplifier that provides adequate air ventilation. Mount the amplifier securely, ensuring it is not upside down. -

Setup
Additional setup instructions may be found in the product manual or on Hifonics.com/product-manuals.
A. Input Mode
Crossover Mode
The Crossover Mode switch sets the type of crossover that will be active. 4 channel models will have two switches, one for each set of channels.
High pass Adjustment
The HPF(high pass filter) control will limit the output below the selected frequency. This is typically used to protect midrange and hi frequency speakers from damage and to allow a smooth transition from a subwoofer.
Low pass Adjustment
The LPF(low pass filter) control will limit output above the selected frequency. This is used to allow a smooth transition to the higher frequency speakers
Bass Boost
The Bass Boost control will increase the power output at 45Hz for more pronounced bass. Exercise caution when using this control. Increase the level in small amounts until distortion is noticed, then back off a littl
Remote Level Control
Some models include a bass remote. Avoid adjusting the bass remote while operating vehicle.
Level Setting
This is a critical step to insure your amplifier is properly adjusted to match the signal output level of your source unit
THIS IS NOT A VOLUME CONTROL!
- If possible, with the source unit off, confirm that the primary volume control is turned down (counter clockwise).
- Turn on the source unit (CD, or MP3 player). Re-confirm that the volume is turned down. Make sure the source unit controls; balance, fader, bass and treble are all set to center or “O” adjustment. Make sure that the green LED on the end of the amplifier is illuminated.
- Play a clean musical selection of which you are very familiar. CD is preferred.
- Do not use radio signals for level setting. Hit play and start turning the volume of the source unit up.
- Stop increasing the source unit volume when you reach 3/4 (about 75%) or until you hear speakers begin to slightly start producing distortion.
- Increase the amplifier level (clockwise) until distortion is heard, then back the level down (counter clockwise) until the distortion is eliminated. Small adjustments may need to be made to balance the levels of multiple amplifiers.
