The system uses TDA-series amplifier chips (like the U6 and U7 TDA amps mentioned on Head-Fi.org ). These chips are often bootstrapped together to drive the subwoofer, where one chip handles the positive feed and another handles the negative.

Connect the positive leads of your RCA or 3.5mm jacks to the respective audio pins: Pin 3 and Pin 4 Rear Left/Right: Pin 5 and Pin 6 Center/Subwoofer: Pin 2 and Pin 1

Three 3.5mm stereo mini-jack cables (stripped at one end) or RCA pigtails. One Toggle Switch (for the power/standby trigger). resistor (quarter-watt). Heat shrink tubing and a precise soldering iron. Step-by-Step Wiring Sequence
Logitech Z-5500 wiring system is primarily centered around the connection between the SoundTouch Control Center (the "control pod") and the , which houses the system's power supply and amplifiers

It is critical to maintain consistent polarity. If you reverse the red and black wires on one speaker, that speaker will play "out of phase." This leads to thin, canceling bass frequencies and a disorienting soundstage where the audio seems to come from nowhere specifically. If you ever need to extend the cables, use standard 18-gauge speaker wire or thicker for the best signal transfer.
If the system plays audio but emits a loud, constant hum, the signal ground network is broken. Verify that is fully connected all the way through your cable. If Pin 7 loses continuity, the audio inputs will use the chassis ground as a return path, introducing massive ground-loop noise into your speakers.
With this wiring diagram, a $10 soldering iron, and a standard VGA cable (for the pod inputs) and a 6-pin DIN cable (for the pod-to-sub link), you can resurrect a Z5500 from the dead. The blue LED around the input jack, dead
