That sounds serious. Is that for noise reduction, ground safety, or both? Do you just use a multimeter and look for voltage drop?
While I've installed a few amps in previous vehicles I've never actually tested my ground point. I just used whatever other folks with the same vehicle recommended.
Also, I could've grounded to the battery directly but the ground cable would've been like 7' long. Is that an issue?
