So I plan to go wheeling this weekend and my radio speakers are giving me feedback. This is probably one of my most critical pieces of equipment needed. Everything was fine until I put in my new switch panel. I'll probably need to draw some MS Paint goodness to explain the layout. But the amp for the radio is under the center console. The center console has my CB and my new switch panel in it. Now logic would dictate that it's the new panel causing the issue since it wasn't there before I installed it but I also updated radios. My grounds are fairly short IMO (<6"). Question is, how to do I fix it? One solution I've found is cranking the volume up and then the music drowns it out but when it's turned down I get the annoying buzz. Any help is appreciated.
 
Check to see if you have any power wires running next to your speaker wires. This will give you feedback.

LOL, I have never had a radio in any of my wheeling rigs.
 
What kind of feedback? Squelch? Engine noise? Does it change in pitch or volume w rpms?

I didn't have it on. I have noticed that it only gives feedback when it's running. With the Jeep not running I don't get any.

I don't remember but is the battery in the back? Large battery cable running under the console to the battery?
 
Feedback when running is usually ground related. Is the ground for the radio going straight to the battery? Also sharing power on the positive can give feedback, as in if the positive is tied into other things and not on it’s on dedicated power.
The red wire is for the switched power wire that tells the radio to come on, and the yellow is constant power that keeps memory. They should not be put together and the red positive should be connected directly to the switched ACC wire for the fuse box. I always run the yellow directly to the battery in an older rig like that.

That’s all I got.

I'll check that. I know the red is hooked to the panel but I don't remember the yellow wire's route. The ground for the radio is not directly to the battery. I do know that.
 
Tune into the lowest AM radio channel. Go drive like a complete asshole or what have you. You can actually listen to your transmission shifting and spark plugs firing transmitted through the speakers, through the radio just like being in some sort of freaky wind tunnel.
No shit, it actually works and I do it all the time.

Factory vehicles have some sort of a filter I think that keeps the electrical noise out of the system.

They do. I straight wired the radio to the battery in my 03 GMC because the adapter plugs are somewhat pricey. It transmits every damn thing.
 
As stated above. If you have a power wire near the speaker wire you can get feedback. I believe my truck has power down the drivers side floor, and speaker wires down the passenger side to alleviate this.

I've been using RCA cables out the back of the radio to the amp. From the amp, I take the speaker wires down the passenger side.
 
amp under console, worked fine until you installed switch panel in said console, my guess is you unhooked the amp ground at some point during the switch install and it didn’t make as good of a connection afterward.
 
move ground to another location.
led could cause noise, are the switches lit (have lights)?
 
The RCA’s next to power supply can also make an interference issue. Battery power (plus or minus) needs to be separated from anything carrying voice signal (RCA, speaker wire).
 
I keep coming in trying here to figure out what the emergency is, but I've yet to see it :confused:

It's a joke. I think most folks figured that out :flipoff2:

I'm aware :flipoff2:

But it catches my attention everytime I log in, and my eyes jump to it because Im like Lassie and want to help, then I realize it's just your joke emergency thread. :mad:
 
shielded cable will solve this problem also, assuming you properly terminate the shield/drain
