I just bought the Cobra 19 Ultra III from Walmart so I could setup a PA system in my truck. I've browsed through the other threads about this but am still confused on what else I'll need besides the CB and speaker. I'm also confused on how to wire everything.
CB antenna too. Walmart or Radio Shack. You can get a glass mount type or one to hard mount on metal. I would not want to put one on the roof. Remember you will need to remove the metal rod to go through a car wash. Good luck.
The power cord that came with the Cobra is not long enough to reach my battery. Anyone know where I can get some longer power cord? I've tried Best Buy and Radio Shack with no luck
I have the same radio. I spliced the power cable into the cigarette lighter wires under the radio. I mounted 2 antennas on my rear bumper and ran the coax under the truck along the frame and through a grommet on the driver side floor and up to the dash. PA is mounted in front of my radiator and the cable is just ran through the firewall to the radio.
If all you want from the CB radio is the PA system, then you do not need a CB antenna or mount. Simply keep the switch in the "PA" position.
All it needs is power and ground. Black wire to any good ground location: many metal brackets with bolts behind the dash area. As to power, I assume you want the PA to work without the truck running, so a "hot" battery lead such as the accessory plug (a.k.a. cigarette lighter) is a good one.
You could look on the internet for a plug that you could wire the CB radio's ground and power lead to so that the CB radio simply plugs into the accessory plug; then you could remove it at will, as the speaker will have a jack type connector that plugs into the CB radio unit. This way, it's all portable, and easily removed when not in use (theft prevention).

You beat me to it.
The cord is not long enough because no one wires directly to the battery.
You need to either add a fuse in the line and use a powered source or use a source that is already fused, as done in a previous post using the lighter. A CB draws very little power so borrowing from another source should not be an issue in most cases.
Personally I prefer to go to the fuse block and find an unused but powered spot and tap in there using a blade connector and put a fuse inline.
The area I bolded above is also a great idea if you want it removable or somewhat portable.
