Insert the marked (red) wire into the + terminal and the unmarked (black) wire into the – terminal on each satellite speaker, then connect the other ends to the corresponding L and R inputs on the low‑frequency box.
Check that all connections are correct and secure, swap the speaker cables to the opposite channel to identify a faulty receiver channel, and verify the balance control on the amplifier.
Keep at least 2 feet (0.6 m) of separation between the low‑frequency box and any television screen to avoid interference.
