2011 lr4 cliking noises coming through speakers

[ugmw177]

my lr4 just started haveing clickcing noises through the speakers even with the infotainment system powerred off. any suggestions?

Mine did that when the alternator was spiking. Do your lights strobe at all at night? Headlights or dash lights.

 

[ugmw177]

hmm, will look tonight. did you have to replace the alternator?

 

[MellonRover]

Yeah, I did and problem solved. Have a charger port that shows voltage, best $4 spent on this thing so far. I can monitor voltage real time

 

[ugmw177]

lights are not flickering

 

[MellonRover]

Is it a clicking or more of a snap like a bug zapper?

 

[ugmw177]

kind of both.

If the sound varies in frequency with engine RPM variation, the alternator is a good suspect. Otherwise…a capacitor in the amp module? IDK

 

[ugmw177]

thanks, sound does not vary with rpms. I found last night that it seemed the positive battery cable was not very tight. son had to have battery replaced a couple of weeks ago. I re-tightened it and started car..no clicking noises but have not driven it yet. we shall see.

I bet you found your culprit.
Alternator was probably freaking out a bit because of the loose connection. The alternator varies output based on what voltage it sees.
