How do I wire up a external speaker to a Uniden SMG1525DT Radio?

1-800-554-3988 or check local for a marine/radio (ask the local PD or Fire who repairs their radios) repair shop. The ACC cable from the back has wire colors orange(+) and black(-) for external speaker wire connections. Connect a 8 ohm speaker to eliminate the internal speaker gone bad. Have a nice day.

nothing,thats what its supposed to do. Don't try transmitting on pa though you will blow that speaker. the type you would need is a bull horn speaker.

Some radio's do this (specifically Uniden) for some unknown reason. Ideally you plug a speaker into the PA output and when you switch to PA mode, the CB transceiver part should turn off and only your voice should come out of the PA EXT speaker to make it act like a personal megaphone.

Hi!
From your owner's manual (page 12) use the blue(-) and the brown (+) wires from your GPS/External speaker connector cable to your external speaker. I've included the owners manual link to your radio.

I will assume you have also looked for the schematic as a Cobra 29ltd which is the same radio----Check the internal speaker with a meter first and also examine the external speaker jack which will cut the inside speaker off.

Lastly a microphone with a broken wire in any area will kill receive audio.

Make sure squelch is turned down enough---if meter shows signal and no audio the internal speaker may be bad (plug one into external jack on rear of the radio).

If the radio transmits and shows it (or someone can hear when you xmit) the problem is in the audio circuit of the radio.

Check internal/external speaker AND SWAP THE MIC as a mic with a broken wire inside or open element as well can cause this.

I realize this question has been here forever, but I've included the link to the Owner's Manual in case anyone requires it. Page 5 shows which wires go to/from external equipment. Orange (+) and the small black (-) are for your external speaker. Green is + for gps data in while the brown is GPS ground. Yellow is not used.

Your scanner has four connections on the back. Looking at the rear, from left to right, are the power jack (10 volts AC, you need an adapter for this), an external speaker jack, the AM antenna connection, and the scanner antenna jack.

The AM antenna jack is for the reception of AM radio station signals. The scanner antenna jack is for police/fire etc, as well as FM signals.

In case you don't have a manual for your radio, it is available for free here:

you need to wire up the speaker to the orange and black wire. orange is speaker positive and black is speaker ground the other wires are as follows thick black= dc ground orange= external speaker positive black= external speaker ground green=gps data in brown= gps ground yellow= nc

the reddish-orange one and the brown one. The green and yellow ones are for data coming in.
