Connecting the Cobra HG S100 to Your CB Radio
Hookup Steps
Connect the HG S100's plug to your CB radio's external speaker jack — standard on Cobra 29 LTD, Cobra 148, Uniden PC78, and most other CB models. No wiring diagram or splicing needed: it's plug-and-play.
PA Speaker Hookup
For PA use, connect your radio's PA speaker output per your radio's manual; the HG S100's 15-watt handling makes it a capable external PA voice projection speaker when wired to the PA jack.
Cobra 29 LTD Compatibility
Yes — the HG S100 works directly with the Cobra 29 LTD's rear external speaker jack. Route the cable under the dash and mount the speaker near the driver for the loudest result.

Comparisons
The HG S100 shares its 15W/4-inch platform with the HG S300 but omits the noise-canceling filter, making it the budget pick for quieter environments. Choose the S300 if you drive a loud diesel cab; buy the S100 to save.
