You’re replacing the IEC C14 appliance inlet (the male chassis connector on the speaker). Good news: it does NOT pop open from the outside, and you should not just pull it out.
Since this is a mains voltage (230V) part, safety is critical.
- 🔌 Unplug the speaker from the wall
- ⏳ Let it sit for 10–15 minutes (internal capacitors can hold charge)
- If you’re unsure at any point → better let a technician do it
These connectors are usually mounted in one of two ways:
- Held in place by plastic retaining clips
- Removed from inside the cabinet, not from outside
- Held by visible screws (yours does not appear to be this type)
From your photo, it looks like a snap-in panel mount IEC C14.
- Remove the rear amplifier plate from the speaker (usually several screws around the edge).
- Carefully pull the plate out.
- From the inside, locate the IEC connector.
- You will see two plastic retaining tabs (one on each side).
- Use a flat screwdriver to press the tabs inward while pushing the connector out.
👉 Do NOT try to pry it out from the outside — you’ll damage the housing.
Inside you’ll see three terminals:
L = Live (brown wire)
N = Neutral (blue wire)
⏚ = Earth (green/yellow wire)
Often marked:
Take a clear photo before disconnecting anything.
Most IEC C14 inlets use:
- 6.3mm spade (Faston) connectors
- NOT solder directly
- Twist wires together
- Use tape
- Leave exposed solder joints
- Use crimped insulated spade connectors
- Or reuse the existing ones if they are in good condition
If your new inlet has solder tabs:
- Solder properly
- Use heat-shrink tubing
- No electrical tape as primary insulation
Before reassembly:
- Make sure earth is firmly connected
- No loose strands
- No wires touching metal parts
- Connector fully clicks into place
If this speaker is a Peavey active (powered) speaker, it contains:
- Mains voltage
- Large capacitors
- Potential shock hazard
If you’re not comfortable working with 230V wiring, this is a quick job for a repair shop.
