Extension speaker for CB radios

The RoadPro RP-100T adds a 4-inch external speaker to citizens-band installations. It connects through a 10-foot cord ending in a mini plug and includes a mounting bracket with hardware. The unit suits drivers who want clearer audio away from the cab's main unit.

Thermals noise and power draw

Peak power handling is rated at 12 watts into an 8-ohm load. The passive design has no fan or amplifier, so it adds no electrical noise and draws no power beyond the radio's output stage. Heat remains negligible during normal voice communication.

Questions about this item

How do I mount the speaker and connect the 10-foot cord to my CB radio?

Use the supplied mounting bracket and hardware to secure the 4-inch speaker in your chosen location, then plug the 10-foot cord’s mini plug into the CB radio’s external-speaker jack.

What maintenance or replacement will the RP-100T need over time?

The speaker is a passive 8-ohm, 12-watt unit with no user-serviceable parts; if the cone or voice coil ever fails, the entire speaker must be replaced.
