Setup
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.
The XOVE eR Mode switch sets the typ
of crossover that will be active. 4 channel
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, conrm that the primary volume control is
is
turned down (counter clockwise).
2. Turn on the source unit (CD, or MP3 player). Re-conrm that the volume
turned down. Make sure the source unit controls; balance, fader, bass and
onLEDtreble are all set to center or “0” adjustment. Make sure that the green
the end of the amplier is illuminated.
3. Play a clean musical selection of which you are very familiar. CD is preferred.
volumeDo not use radio signals for level setting. Hit play and start turning the
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 amplier
is properly adjusted to match the signal
output level of your source unit.
THIS IS NOT A VOLUME CONTROL!

Congratulations on your choice of a Crunch amplier. This
“Quick Start Installation” guide is meant to help you “hook
up” and play music.

Place terminal in a secure
position so that it won’t
accidentally contact the
negative battery post
Properly route power,
speaker and RCA cables
through the vehicle.
Choose a mounting location
that will provide adequate air
ventilation. Mount the amplier to
a secure surface. Do not mount
the amplier 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 amplier. Choose a
location that is close to the
amplier. Completely scrape
away the paint and use a nut

CAUTION
Many new and factory radios require a reset code when
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
