Quick Start
Here are a few general steps to get your ACM-4.300 amplier up and
running:
1. Undo the +12V and Ground connections to the car battery
before making any connections to the amplier.
2. Pick a mounting location that will provide access to the controls
and connections, provide plenty of good ventilation, and also
protect the amplier from heat, moisture, and dirt.
3. The ACM-4.300 amplier needs to be securely mounted using
the four mounting holes located in each corner.
4. Before drilling any holes, take every precaution to prevent
any damage to fuel lines, power and other electrical wir-
ing, hydraulic brake lines, and other systems, that might compro-
mise vehicle safety.
5. When making connections, designate red RCA plugs as right,
and designate white, black, or grey plugs as left. This is a good
idea for consistency.
6. Use quality interconnect cables.
7. Connect the +12V input terminal of the unit to the +12V termi-
nal of the vehicle battery, using 8 to 4 AWG.
8. Connect the Ground terminal of the unit to the chassis of the
vehicle, using the same wire gauge as the +12V power wire.
9. Connect the remote power terminal of the unit to the remote
turn-on switch of your source unit. Alternatively, you can skip
this connection and use the GTO™ Signal sensing.
10. Connect your audio inputs to the unit – either speaker-level or
line-level RCA… not both.
11. Connect your loudspeakers (minimum impedance of 2 Ohms
stereo, or 4 Ohms bridged mono).
12. When all connections are made, reconnect the vehicle battery.
13. Adjust your gain settings to maximise your signal level.
14. Set the ACM-4.300 crossovers to the frequency recommended
by the loudspeaker manufacturer.
15. Enjoy the drive!
