Insufficient grounds, are you getting the most out of your system?

[QUOTE="trumpet, post: 8362008, member: 628688"] It's impossible to have no voltage drop. Even if it's only 1" of power wire a sufficiently high count DMM is going to read a drop in voltage. The ground circuit is absolutely crucial for maximizing your system's performance, but you don't have to do a voltage drop test across the full length of the vehicle. Pick two adjacent connection points in the circuit, such as between the amplifier and the chassis ground location. You should be grounding to the chassis, not just laying a ground cable directly to the battery. If your system needs more than 4 AWG wire for the current draw you may need a parallel ground cable. That means it goes from the chassis ground at the equipment up to the battery's chassis ground. [/QUOTE]
