How to Install CB Radios on newer model trucks

Postby rccrazy30 [OP] » Jun 11 2013, 1:14am

How to install a CB:

I had a hard time finding any information on installing a CB in the newer chevy trucks (07 up) i have pretty much got it down after a few trial and errors. The hardest part about this mod is mounting the antenna properly.


Step 1: you need to select all the parts you need. This is my parts list
    Radio:
    Cobra 29 LX Chrome (Highly recommended if you have room) if space is tight take a look at the Cobra 25 lx
    Antenna: FireStick 4’
    Coax: Firestik FireRing
    Mount: Firestik 3-Way CB Mount
    Other: Heavy-Duty CB Antenna Spring, and Firestik CB Antenna Quick Disconnect, PA horn, SWR meter

Step 2:
There are a bunch of different ways to mount the antenna this is the way i chose to mount mine. Because of the design of the bed it is difficult... if you chose not to use the Fire ring type cable make SURE you bring the mount up as high as possible to avoid kinking the coax wire with cab vent. I also recommend making a spacer to move the antenna bracket so it doesn't hit the bed as much. when putting the antenna stud MAKE sure you have a nylon washer on each side of the mounting bracket if you miss this step your radio won't work properly. Unfortunately it is imposible to get a good photo of the mounting area. The reasoning for adding the spring and quick disconnect is to get the base of the antenna above the top of the bed. You have to bolt the mount on aprox 7" bellow the top of the bed. If you just screw antenna to a stud you will find you will never be able to get a good SWR #

TIP: Getting the bolts through is tricky i took a open end wrench taped and zip tied it to a long screwdriver then took the bolt and used some electrical tape to keep it from falling out this worked like a champ once it was tight just pull the wrench out and break the electrical tape

Step 3:
Running the Cb coax cable some will say start out and work your way in; don't try it it doesn't work. You need to unbolt the rear seat and move it out of the way so you can get your hand behind the insulation on my truck theres a accuses patch that easily opens. I used a coat hanger and taped the end of the Cb Coax to the end and guided it through. After that to get the coax to the front the best way to get there is un doing the kick plate CAREFULLY these pieces are easy to break. once you get to the front you will most likely find you have extra cable DO NOT cut the cable simply bunch the cable up like a hot dog zip tie and tuck away.

Step 4:
getting power to radio. There are a few different ways to this the best way is to run power directly from the battery. The only downside to doing this if you forget to turn off your radio your in trouble. I ran my power line from the battery across the engine bay and to get through the fire wall i simply went through the parking brake cable hole. (this is also the same hole i used to get the PA wire through. to make sure i won't forget to turn my radio off i added a separate switch with a LED indicator.

Step 5:
Mounting the radio and mic. if you have a truck with at bench seat this is pretty easy if you have a center console this could be a little more difficult but i simply just used the self taping screws and attached it to the plastic. with the mic i chose to mount mine in the 4x4 shifter its out of the way but easy to grab

Step 6:
Testing and calibrating your radio. If you got a radio with a built in SWR meter you won't need an external meter (still recommend getting an external). if you're using an external meter hook the antenna end up to the input that says Ant then use the jumper on the other end to hook into your radio. next you need to get your truck into an OPEN area clear as possible from trees buildings etc.

    1.Set the switch on the SWR meter to “FWD.”

    2.Turn the radio to channel 1.

    3.Key the microphone (depress the button and hold it).

    4.Turn the knob on the SWR meter labeled “SET” or “ADJUST” until the needle reaches the setting position at the end of its range.

    5.While still keying the microphone, flip the switch on the SWR meter to the “REF” or “SWR” position.

    6.Quickly record the reading given by your SWR meter and release the transmit key on your microphone

    If the SWR on channel 40 is higher than that on channel 1, your antenna is too long.
    If the SWR on channel 1 is higher than that on channel 40, your antenna is too short.
Step 7:(optional)
most radios have output for a PA system so i added one just for the heck ouf it. Its pretty simple just run a wire from the PA through the fire wall and into the back of the CB.

Last tip is buy good quality stuff don't cheap out or you will be redoing it

I got an amp for my PA speakers (I'm mounting 2 that are similar to yours) but I haven't hooked everything up yet. The amp has an adjustable volume control though, so I'm going to start with it all the way at low and work from there. It looks like in the picture you put the PA on the spare battery tray. Have you had any problems with it there? I don't want to put mine there because I plan to run a dual battery setup eventually, but it's hard to find a good spot otherwise.

I think it would have been easier to get power and ground from the Upfitter port in the power distribution block in the drivers footwell. You can get the gm connector and pins for pretty cheap online. One of the feeds in that port is tied to RAP, which would prevent you from leaving it on.

Anyway...nice install and write up.

What's the Upfitter port? There's a box to the left side of the driver's footwell in my truck I was hoping to tie into, but I haven't been able to get the cover off of it.
