Quick Start
Here are a few general steps to get your ACX-300.4 amplifier up and
running:
1. Undo the +12V and Ground connections to the vehicle battery
before making any connections to the amplifier.
2. Pick a mounting location that will provide access to the controls
and connections, provide plenty of good ventilation.
3. The
ACX-300.4 amplifier 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 wiring,
hydraulic brake lines, and other systems, that might compromise
vehicle safety.
5. When making connections, designate red RCA plugs as right,
and designate white, black, or gray plugs as left. This is a good
idea for consistency.
6. Use quality interconnect cables.
7. Connect the +12V input wire on the included wiring harness
assembly to the +12V terminal of the vehicle battery, using the
appropriate gauge wire.
8. Connect the Ground wire of the power wiring harness assembly
to a ground source such as the negative battery terminal, vehicle
chassis or other ground source, 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 maximize your signal level.
14. Set the ACX-300.4 crossovers to the frequency recommended by
the loudspeaker manufacturer.
15. Enjoy the drive!
