ACM-4.300 2 Important Safety Instructions 1. Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with a dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturer's instructions. 8. Do not install near any heat sources such as mufflers, silencers, exhaust pipes, or other apparatus (including amplifiers) that produce heat. 9.
Connection Panel Features 2 3 4 5 1. Fuse 30A - Replace the fuse only with the exact same style and Ampere rating. Disconnect 12V power before changing or inspecting the fuse. 2. Power Input Terminal + 12V -This screw terminal connects to the+ 12V battery binding post of the vehicle. Use quality insulated wiring of the recommended wire gauge, such as wire gauge 8 or thicker. Thinner wire may cause an overheating hazard due to the large currents involved. 3.
ACM-4.3 00 4 6. RCA Analog Line-Level Inputs -The line-level outputs from the head unit or factory installed radios can connect here, so the ACM-4.300 will receive the line-level audio signals. Do not use the speaker-level inputs if you are using the RCA line-level inputs. 7. Speaker-Level Output Terminals -These screw terminals connect with speaker wire to your loudspeakers. Make sure that the average combined speaker impedance does not dip below 2 Ohms per channel.

Gain Controls -These controls allows you to adjust the overall volume output level, with counterclockwise decreasing the volume, and clockwise increasing. One control is for channels 1 and 2, and the other for 3 and 4. The setting procedure is given on the next page, and involves nerves of steel, a steady hand, grit, determination, and the thought that you are making the world a better place. 13.
Quick Start Here are a few general steps to get your ACM-4.300 amplifier up and running: 7. Connect the+ 12V input terminal of the unit to the+ 12V terminal of the vehicle battery, using 8 to 4 AWG. 1. Undo the+ 12V and Ground connections to the car battery before making any connections to the amplifier. 8. Connect the Ground terminal of the unit to the chassis of the vehicle, using the same wire gauge as the+ 12V power wire. 2.
