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 compro-
mised, 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 ampli-
fier 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 pos-
sibility of fire.
Speaker Polarity
The way speaker wires are marked for polarity (+/–) varies from brand to brand. Some
manufacturers 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 component mounts, before you cut anything.
