Hello all,
I recently installed my stereo system in my 2019 Raptor, I know there's a Raptor forum, but I figured id try here. I'm having some issues with my NAV TV A2B. When I open my door I can hear the remote relay clicking on and off several times...Zen unit is powering on and off. If I get in and push the start button right away I get a squeal coming from my speakers for a second and then goes away. If I let the system power on and off like it does multiple times and then push the start button, it doesn't squeal. This is my system layout: A2B with power and ground hooked up to system distribution blocks. I have a remote relay hooked up between the ZEN and 3 JL Audio amps. All Amps have low level RCAs coming from the Zen. Does anyone know why the clicking on and off is happening and why I'm getting a squeal at start up?

may have to go to fuse 23 in kick panel......someone with more knowledge will answer there tho...

 

Thank you!

 

Is your ground distribution block going to the battery or to the body of the truck? I believe the Zen manual says it has to be grounded directly to the battery.

 

So you need to connect both power and negative to your buss bars or direct connection to the battery. Make sure there are no ground loops. Also go into Forscan and make sure engine noise is disabled. I had the same issues with mine on my 2019 raptor

 

You can also check resistance from your + wire all the way to the battery and make sure it's with in spec of what's on the directions

 

yes, my ground distro block runs straight to my battery.

 

Power and ground go straight to the battery. No ground loop issues. So what did disabling the engine noise do? How did it effect your system? I don’t think that is my issue here. I don’t even think my truck had the engine noise function.

 

power and ground run straight to the battery.
