Installation Notes
- Confirm the vehicle provides a suitable 8–12V power source before connection.
- Verify speaker placement and enclosure clearance before final mounting.
- Keep wiring clear of driveshafts, steering linkages and hydraulic components.
- Depending on the vehicle and channel layout, additional splitters or extensions may be required.
GASHEAD RC Setup Note
Sound quality depends heavily on speaker placement. Mount the speaker where the cone is not obstructed and where the body or cab can act as a modest enclosure rather than trapping the sound completely. Before hard-mounting the module, test all channels and confirm that your power source remains within the specified 8–12V range.
