Use existing sat radio power cable for CB?

[unabashedpraise]

I bought my rig with an aftermarket Sirius sat radio already installed. Unfortunately some punk idiots decided they would try to steal it. "Punks" because they are stealing what isn't theirs. "Idiots" because they were unsuccessful (it's not THAT hard!), but broke the docking cradle. The cradle is shot and a replacement is hard to find, the only one I have found was $40. Bye bye sat radio! I only used it during football season anyways.

I am currently trying to find a good place to install and power my Uniden 510 xl CB and antennae on the zj. I want to hard wire it so I don't have to use one of my precious 12v plugs. The sat radio was powered by clips attached to the power and ground wires on the back of the oem dash CD player and also has an inline fuse on the ground wire. It's seems like a decent setup and I was thinking of just stripping the end of the wires and using this to power the CB so that everything would be setup and ready to go, no need for running cables and such.

This is the only info I could find on the net about the sat radio: Kenwood H2EC Specs: Audio Output: (560 ohms) 776mV RMS, Fuse: 3A fast blow, Power Supply Requirements: 9 - 16v, negative ground.
Uniden 510xl specs: Input Voltage: 13.8 V DC nom. (+ or - ground), Current Drain: TX: full mod., 1.7A RX: with max. audio output, 1.7A

Is the connection going to supply enough power to the CB and radio without blowing the factory fuse? Does the 3a fuse need to be changed out?

I'm going to use the CB sparingly, mostly for trail use and the occasional traffic chatter.

Shouldn't blow the fuse, however most CBs are finicky about the quality of power they receive (it doesn't take much voltage drop for them to fuzz out or sound garbled over the air).

I would just run a separate power wire for the CB through the firewall straight to your battery (#12-14 gauge with a 3-5A fuse should be fine for that small Uniden unit). Most vehicles you can usually find an unused grommet or other location where you can punch a wire through. The ground (-) wire can go under the dash somewhere (bolt holding the steering column, etc.) this way you only have to run one wire through.

If you run your radio and the CB at the same time you probably will blow the fuse. Also that radio wire might be too light a gauge to get full power output on the CB or risk overheating the wrie. I agree with above that you'll be much better off running a power wire either from the battery or from it's own location on the fuse block with it's own fuse. Remember that CB is very limited even with a full 12volts input so I wouldn't want to compromise even a little power with too small a power wire.

Both posts make sense, thank you!
