Wiring Diagrams for Constant Resistance Speakers:
Method 1: One Speaker, Two-Wire Wiring Diagram

Image: Wiring diagram illustrating how to connect one speaker using a two-wire method. The host output connects to terminals 1 and 2 (input), and the speaker connects to terminals 3 and 4 (output).
For connecting a single speaker using a two-wire configuration, connect the audio source's output to the controller's input terminals (labeled 1 and 2). Then, connect the speaker to the controller's output terminals (labeled 3 and 4).
Method 2: Single-Wire Control Wiring Diagram for One Speaker

Image: Wiring diagram showing a single-wire control setup for one speaker. The host output connects to terminals 1 and 2 (input), and the speaker connects to terminals 3 and 4 (output). This image also shows the controller and mounting screws.
This method is similar to Method 1, focusing on a single speaker. Connect the host output to the input terminals (1 and 2) and the speaker to the output terminals (3 and 4).
Method 3: Two Speakers, Single-Wire Control Wiring Diagram

Image: Wiring diagram demonstrating how to connect two speakers using a single-wire control method. Each speaker's host output connects to its respective input terminals on the controller, and the speakers connect to the output terminals.
For connecting two speakers, each speaker's host output should be connected to the corresponding input terminals on the controller. Ensure proper polarity for both speakers.
