Power Input Terminal +12V – This screw terminal connects to the +12V battery binding post of the vehicle. Use quality insulated wire, 8 to 3 AWG. 3. Remote Power Input Terminal – This screw terminal connects to the 12V remote trigger output of some head units. When the head unit is turned on, then the LC-4.

10. Power LED – If you have connected your battery power, vehicle ground, and turn-on lead (or GTO signal sensing) correctly, then this light should be green to indicate the power is ON. 11. Protection LED – The amplifier has built-in diagnostic codes to tell you exactly what is going wrong should the amplifier detect a problem. See specifications page 11 for a list of diagnostic codes. 12. GTO Signal Sense – In the ON position, the LC-4.
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 ventilation slots on the sides are not blocked, and that the heatsink fins are not covered. 3. The LC-4.
Power Connections Head Unit Remote Amplifier +12V Trigger In this example, the head unit has a +12V trigger output that is connected to the LC-4.800’s remote input terminal. When the head unit is turned on, it will turn on the LC-4.800 amplifier. Alternatively, the GTO signal sense feature can be used to gently turn on the LC-4.800 amplifier when an audio input signal is detected. In this case, the connection to the LC-4.800’s remote input terminal is not required.
System #1: Using speaker-level inputs Front High Speaker-level output + Speaker-level output 80 Hz and above + Factory Radio Rear Speaker-level output + Front Low Speaker-level output Line-Level Speaker-level output 80 Hz and above + ACR-1 Notes: Both crossovers are set to 80 Hz high-pass. If the AccuBASS®/ACR-1 switches are set to “disabled” the ACR-1 can control just the line-level output, so you can adjust the subwoofer level on the fly.
System #2: Using line-level inputs + Speaker-level output 30 to 80 Hz and above + 2-Channel Audio Device Left Out Right Out Line-level Line Level + Speaker-level output 30 to 80 Hz and above + ACR-1 Notes: Both crossovers are set to high-pass, and adjusted to suit, depending on if you have a subwoofer or not. If the AccuBASS®/ACR-1 switches are set to “enabled” the ACR-1 and AccuBASS® affects all outputs.
ACR-1 Dash Control Installation Top Lid Removal The AudioControl ACR-1 dash control is a remote level for your LC-4.800 amplifier. It may be mounted under the dash using its own enclosure, or through a custom hole in the dash. The knob should be within reach of the driver, and in a spot where the LED is plainly visible. Disconnect the vehicle battery +12V and Ground connections before installation.
