Hi everyone

I am getting static everytime I apply brakes. I have RCAs running from my 4 channel output to my Mono block due to having a factory HU. I noticed that when I disconnect the RCAs to the monoblock the sound goes. My ground is fine, so my question is do you think my Amp is faulty?

Thanks

What type of ABS brakes does it have?

It was a rhetorical question...

But with that you probbaly can work out that the CAN bus signal maybe near the RCAs, or somehow that could be involved.

Howsit?

Howsit! 😁

I am going rerun the RCAs and see if that helps. Thank you for the feedback!

so i’m assuming you’re using a line out converter or a sound processor since you said you have the factory head unit?If so which model specifically are you using? Make sure you tapped into the correct speaker wires

Yes I have a line out converter which is fine because it was installed by a sound audio company. as soon as I added the monoblock the noise started. I have changed my ground to different locations, moved the RCAs away from the power cable but no luck, it's super frustrating

Have you tried running the power and ground from the monoblock back to where the 4-channel is?
(That could perhaps tell if it is a ground loop issue that only appeared when the monoblock was added.)

Just because it was installed by a “sound company” doesn’t mean it was done right. if you didn’t have the amp in at the time of the installation the company wouldn’t even have a chance to test for proper function. My suggestion is to find out what brand line out converter they used because some LOC’s have the option to have an additional ground hooked up to prevent ground noise
