Working safely with your battery
Disconnect the negative battery terminal before doing any electrical work. Always disconnect the
negative (–) battery post first, followed by the positive (+), and when it’s time to go back together,
connect the positive (+) post first, followed by the negative (–). This can minimize the chance
of sparks and voltage spikes, and is a good general practice when dealing with any DC electrical
system.
Grounding
Bad grounds under are the number one cause of problem installs.
Always use the shortest length of ground wire possible between chassis ground and the amplifier.
Never use a ground wire longer than the one we provide.
The ground wire and power wire are equally important; if either one of them is compromised, the
amplifier’s performance will degrade or cease to function.
Fuses
Always install a master fuse within 12” of the battery for any additional equipment added to your
installations electrical system. The mini-fuse installed on the main amplifier only protects the
internal circuitry, not the wiring. In the event of a short, failure to install a fuse near the battery
can cause damage to your electrical system or the possibility of fire.
Speaker Polarity
The way speaker wires are marked for polarity (+/–) varies from brand to brand. Some manufactur-
ers use the stripe as positive (+), while others use the stripe as negative (–). Be sure to check the
documentation of each component you’re dealing with before making connections.
Cutting Cables
Always route wires and cables safely, avoiding sharp edges and burrs along the way. Use wire loom
when possible. Check for proper length to both termination points, knowing where each compo-
nent mounts, before you cut anything.
