Quick Start Guide

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. Make sure that you follow the plus and

minus polarity markings on the ACM-4.300 and match it to the

polarity of your loudspeakers.

In Stereo operation, connect one loudspeaker to each channel as

shown. The minimum impedance is 2 Ohms per channel.

In Bridged Mono operation, connect one loudspeaker to the in-

ner 2 screw terminals ( Channel 1+ and Channel 2-) as shown. The

mono loudspeaker will receive the power from each channel, and

both channel inputs must be fed an input signal. The minimum

impedance is 4 Ohms. Connect stereo speakers to channels 3 and

4 as shown, or another Mono speaker.
