- Distorted Sound: Reduce the volume level. Check for proper gain settings on your amplifier. Ensure the speaker is not overdriven. Inspect for any physical damage to the speaker cone or surround.
- Intermittent Sound: Check for loose wiring connections. Ensure the speaker wires are not pinched or damaged.
- One Speaker Not Working: Swap the non-working speaker with a known good speaker (if available) to determine if the issue is with the speaker itself, the wiring, or the amplifier channel.
