⚠️ Important Usage Notes

 

1. Strip the cable insulation clean to match the internal socket depth, insert the bare copper wire fully into the adapter, and tighten the set screw securely with the appropriate Allen wrench.

2. Wrap exposed conductive metal sections with heat-shrink tubing or electrical tape after installation to prevent accidental grounding shorts against the vehicle chassis or amplifier heat sink.
