What are some good places to ground in a 00 mustang?
Is the mustang unibody? I'm guessing it is.
Currently grounding sub amp to the trunk where I screwed a ring terminal into bare metal.
Have some whining from my sub amp at 0 volume with car off, so I want to use a better ground to eliminate posibillities.
Besides doing a run to the negative battery post, where are some good spots to ground on in unibody cars?
