I noticed companies (Streetwire, etc.) sell amp power cable (I'm looking at 8 gauge) and amp ground power cable. Is there a difference? They have the same specs, right?
It's however you wire it. The Stinger HPM series uses blue for power and silver for ground. It used to be that red (+) and black (-) were the only choices that you had, but with all the colors of wire out there now, there really isn't a standard anymore. However you want to do it is fine.
