Autotek MM-1125.1D Instruction Manual

Place terminal in a secure
position so that it won’t
accidentally contact the
negative battery post
Power / Ground
cable size
It is critical to use the proper
power and ground cable. Select
the size listed here for your
amplier model. Always use high
quality copper cable.
Cable size recommendations for
multi amp systems are available
on our website.
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.
Bare metal
Connect the RCA cables to
the INPUT connectors. The
OUTPUT can be used to
provide input for a second
amplier.
Connect the power cable to the
positive battery terminal. The
power cable must be fused
within 18 inches of the battery
terminal.
Re-connect the negative
battery terminal making sure it
is securely tightened.
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
and bolt if possible.
DO NOT USE AN EXISTING
FACTORY BOLT!

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

Quick Start
Installation Guide
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 XOVER Mode switch sets the type
of crossover that will be active. 4 channel
models will have two switches, one for each
set of channels.
The HPF(high pass lter) 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.
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
turned down (counter clockwise).
2. Turn on the source unit (CD, or MP3 player). Re-conrm that the volume is
turned down. Make sure the source unit controls; balance, fader, bass and
treble are all set to center or “0” adjustment. Make sure that the green LED on
the end of the amplier 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 amplier 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 ampliers.
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.
