[QUOTE="Lasherž, post: 8704854, member: 679555"] Absolutely not. The ground wire is shorter than the power wire for a big reason, and that's safety. What's the point of having a fuse if the longest length of wire generating heat is an unfused ground? The ground cable should be short. Use the chassis, it's an amazing ground without needing a terminal right to the battery (electrically it basically is, vdrop on ground is minimal). You won't necessarily drain your battery because the ignition cable is, I assume, still going to be connected in line with your key wiring, but it's proper to just screw the terminal into solid metal somewhere behind the radio. Some radios provide a black ground right from the harness and I believe that goes back to the fuse box to ground, which is just fine too, why not both? audiobaun's suggestion of splicing the ground wire from the harness to a grounded chassis terminal is a great idea if that's all you have, a lot of radios come with a ground terminal point already but there's no harm in adding one if you think it's a grounding issue (which are quite common).
