i'm looking to fix the nightmare wiring job that was done to my car. i'm shortening all the ground wires hoping to get rid of the engine noise.

i could hear the engine noise every time i step on the gas. i also noticed that it gets louder when i turn on my headlights. what can i do to reduce/stop the engine noise? does the fact that the noise gets louder when i turn on the headlights say anything?

What's your stereo setup?

Engine noise can result from a ground loop. If you have an amp that's hooked up to a different ground point than the head unit, you can have a ground loop. To fix this, you need to have them both wired to the same ground point.
