NEVER. What the FUCK. I am eliminating about 6 feet of extra wire balled up behind my dash.
And I'm wondering if they installed the Bulldog keyless entry too.... it's just as bad of a hackjob.
People who can't wire things properly need to be strangled with live bare wire.
I am en expert with it, so I do it. I can't weld for shit, so I DON'T weld. Whoever wired this shit in my car should NOT be doing stereo installs.
