So for some reason whenever I hit a switch for my air ride, I hear a popping noise from my speakers. Now I have all my power wires ran on the opposite side of the car an of the RCA wires. I have my grounds all separate from each other all at least 2 feet apart also. I am running a yellow top and all 0 gauge wiring and the big 3. This is the 2nd 4ch amp for the speakers and its doing the same thing as the previous one with the popping noise so I know it is not the amp. This is also the 2nd headunit and the same thing so I know it isnt that also. Someone said something about the magnetic field from the airride because of the valves and they have such a strong magnetic field that it will make that noise unless I filter it or something. What does he mean by that? I was thinking a noise filter for the RCA's do you think that will help or no? BTW this only started happening after the airride was installed.

Do you get any noise when the compressor comes on?
Where are your solenoids getting their power and ground from?

Nope, only when I hit the switches I will get a noise. The power is coming from the battery and the ground is a chassis ground separate from any and all audio equipment, but it is a relay I am using, not a solenoid.
I don't know if it still does it, because I took the subs out of it, but I know at one point when I would shut the doors or shut down the system, the subs and only the subs would make a hum noise that would dull down to nothing but it would take 1 or 2 seconds to die out. However, again I do not know if it still does that but it didn't do it with the speakers, only subs. So maybe we wont even keep that in mind as there are no subs in there any longer.

So the relay drives the solenoid?

No, I dont have a solenoid period. You can either use a solenoid or relay to wire it up, the solenoid I got a few years back when I first put the air on it was defective so I used a relay instead.

No solenoid? I'm confused. I've never seen a relay control air flow.
Either way, both a relay and a solenoid have a coil on them. When they energize and deenergize they are prone to making inducing noise. I would try running a ground directly to the battery from the coil.
Does the pop happen when you first push the button, when you release the button, or the entire time the button is pushed?

hi,
disconnect the solenoid valves electrically from the rest of the control circuitry. test for the noise. do relays click when the controls are operated? if yes, identify the positive and negative sides of the relays, wire a diode, (1N400x)type, band to the positive side. retest for noise. reconnect the solenoid valves, test for noise again. if yes, identify the positive and negative sides of the solenoid, wire a diode, (1N400x)type, band to the positive side.

the relay is just for the power for the compressor. I have valves for the control of the air which the switch box controls the valves. But I get a pop only when I hit the switch and release it, it doesn't do it for the duration of me holding it down.
i have the relay ran like so:
30 to battery +
86 to chassis ground
85 to pressure switch
87 to compressor
87a not used

try the diodes across the coils of the solenoid valves. one diode for each solenoid valve.

The compressor should not kick on and off every time you press the button. The compressor should only come on when air pressure is low. Therefore, it most likely isn't a problem with the relay - it is a problem with the solenoid valve(s) that actuate when you push the buttons.
