Quick Start Guide
Quick Start
Here are a few general steps to get your LC-4.800 amplifier up and
running:
1. Undo the +12V and Ground connections to the car battery
before making any connections to the amplifier.
2. Pick a mounting location that will provide access to the controls
and connections, provide adequate ventilation, and also protect
the amplifier from heat, moisture, and dirt. Make sure the ven-
tilation slots on the sides are not blocked, and that the heatsink
fins are not covered.
3. The LC-4.800 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 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 3 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. Run the ACR-1 remote to the front of the vehicle to adjust the
level on the fly.
12. Connect your loudspeakers (2 Ohm stereo, 4 Ohm Bridged mini-
mum load).
13. When all connections are made, reconnect the vehicle battery.
14. Adjust your input source gain using the MILC Source Clip LED.
This will indicate if the incoming audio signals are clipping.
15. Set the LC-4.800 crossovers to the frequency recommended by
the loudspeaker manufacturer.
16. Adjust the LC-4.800 AccuBass controls to suit. The ACR-1 adjusts
the overall output level.
17. Enjoy the drive!
