Where is your ground located? Does both amps lead to the same ground? Did you put a filter on your tweeter or is it set to full range?

Both my grounds lead to my second battery and that's the weird thing my sub doesn't do it only mids and tweeters plus I got a horrible engine whine as well. Text me I reset my phone and lost your number

Turn the gain down.

if you got a horrible engine whine everytime you press the gas pedal, that's definitely ground loop issue.. I think both your amps and 2nd battery need to ground to full chassis.. That's how I have mine..

I completely turn the gain down like as down as it goes and it still makes the noise

You need to run your grounds to the vehicle Frame as well as the battery.I run 0 ga to the frame back up to a distro block for grounding.Got the Big3 done??
