Carefully route the speaker and microphone wires through the helmet's internal channels to the control unit. Use the double-sided adhesive tape to secure the control unit in its designated spot.
5. Route Cables: Neatly tuck all cables within the helmet's lining and channels to prevent interference with comfort or safety.
6. Reinstall Padding: Once all components are securely in place and wired, carefully reinstall the helmet's interior padding. Ensure no wires are pinched and that the system components do not create pressure points.
