The input MODE switch will “sum” or
combine the right and left channel signals
in the MONO position to improve bass
performance. Select MONO only when the
amp is being used for subwoofers.
typThe XOVE e switch sets the e R Mod
of crossover that will be active. 4 el chann
models will have two switches, one for each
set of channels.
The HPF(hig ss lter) control will limit the h pa
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.
The LPF(low pass lter) control will limit
output above the selected frequency. This
is used to allow a smooth transition to the
higher frequency speakers.
1. If possible, with the source unit off, conrm that the primary volume control is
is
turned down (counter clockwise).
2. Turn on the source unit (CD, or MP3 player). Re-conrm that the volume
turned down. Make sure the source unit controls; balance, fader, bass and
LED on treble are all set to center or “0” adjustment. Make sure that the green
the end of the amplier is illuminated.
3. 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.
4. Stop increasing the source unit volume when you reach 3/4 (about 75%) or
until you hear speakers begin to slightly start producing distortion.
5. 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.

The BASS BOOST or BASS EQ control
will increase the output at 45Hz for more
pronounced bass. Exercise caution.
Increase the level in small amounts until
distortion is noticed, then back off a little.
Some models include a bass
remote. Avoid adjusting the bass
remote while operating vehicle.
This is a critical step to insure your amplier
is properly adjusted to match the signal
output level of your source unit.
THIS IS NOT A VOLUME CONTROL!

Properly route power,
speaker and RCA cables
through the vehicle.
Choose a mounting location
that will provide adequate air
ventilation. Mount the amplier to
a secure surface. Do not mount
the amplier upside down.
Using spade terminals, connect the
+12V to the power cable from the
battery, the REM to the source unit
turn-on wire and the GND to the
chassis ground..
Strip each cable back approx 1/2”,
connect the +12V to the power
cable from the battery, the REM to
the source unit turn-on wire and the
GND to the chassis ground..

The chassis ground connection
is critical to the performance
of the amplier. Choose a
location that is close to the

disconnected from battery power. This is an anti-theft
feature. Before unplugging power, you must determine if
your radio/source unit requires a reset code. Check the
