That’s not a very good ground, not too bad, but ideally you’re looking for something below .5 ohms. Run a longer ground wire to a better ground, and make sure it’s bare metal and a steel, not a zinc coated boltI just tried testing the grounds to my amps, which I've never done before. They were testing at 0.6 to 0.7 ohms, and I couldn't find a single piece of metal above the spare tire below 0.5 ohm. I'd look but it's a 3 person job to move the box.
