Logitech Z5500 Wiring Diagram Exclusive !link! (720p)
If you are opening the subwoofer box to fix a dead channel or replace the amp plate, you need to identify the wire colors for the speaker outputs. These connect the amp board to the spring clips on the back of the sub.
The Logitech Z-5500 system had multiple revisions, which changed how the satellite speakers physically connected to the subwoofer.
The satellites are 8-ohm speakers. You can replace the factory wire with high-quality 16-gauge or 18-gauge speaker wire, but keep the polarity consistent (positive to positive/red to red).

Subwoofer hums, but no satellite sound.
Check the physical fuse located right next to the AC power cord on the back of the subwoofer. It requires a T2.0A or T2.5A 250V slow-blow fuse . If the fuse is fine, check Pin 8 and Pin 9 on your DB15 cable using a multimeter to ensure voltage is reaching the pod. Popping Noises or Constant Hissing

Logitech Z-5500 Control Pod Bypass Subwoofer Cable 5.1 ... - eBay
These units feature a detachable control pod cable that plugs into a DB15 port on both the pod side and the subwoofer side. The internal amplifiers utilize a slightly higher voltage tolerance on the logic board.
A pervasive hum that does not change when adjusting the volume indicates a grounding loop or open shield. The satellites are 8-ohm speakers

Note: Wire colors can vary slightly by manufacturing year, but the following is the standard for most revisions.
The Logitech Z-5500 is a legendary THX-certified 5.1 system, but due to its age, many units are succumbing to wiring rot, severed control pod cables, or blown subwoofer amps. Because Logitech does not publicly release official schematics, finding the correct wiring diagram is often a frustrating scavenger hunt.
