ALS-500M
The battery should be securely mounted in a well ventilated area. The hydrogen gas that forms when
the battery is charging can be explosive if trapped in a confined area. Remember that hydrogen gas
rises, and it can be trapped in the top of any compartment. Vents must exit vertically above the area to
be ventilated. Ventilation holes below the battery do not remove the hydrogen gas.
The battery mounting must be secure and outside the passenger compartment of the vehicle. A poorly
secured battery can be a lethal projectile in a collision. A suitable battery box can be obtained from
marine accessory stores. WARNING: The installation of a second battery increases the hazard of
fire or explosion in an accident!!

Unibody Vehicles

The amplifier ground connection should attach to a large fixed body panel of the vehicle. Never depend
on a connection made to the dash board, doors, trunk or hood of a vehicle for grounding. Use the
heaviest and shortest connections possible. The best conductors for all ground connections are densely
woven copper braiding or heavy stranded cable that is rated to safely carry 100 amperes. Multiple
ground connection points are usually superior to a single ground connection point.
The negative terminal of the battery is almost always directly grounded to the engine block of the
vehicle. This prevents the high starter motor currents from flowing through the engine and drive line
bearings. To be sure that the high amplifier current does not flow through the driveline of the vehicle,
and to minimize the voltage drop in the negative supply lead, the body (chassis) of the vehicle must be
securely grounded to the engine.
The engine block of the vehicle is almost always poorly grounded to the body of the vehicle. This is
usually accomplished by a small gauge wire that connects the negative post of the battery to the chassis
of the vehicle. Remember that the manufacturer of the vehicle calculated the size of the grounding
conductors to only handle the normal accessory electrical load of the vehicle. Improvements to this
ground are mandatory. Improving this ground will also reduce ignition noise and help prevent
interference or damage to the sensitive control devices in modern vehicles. This ground can be
improved by connecting a heavy ground wire from the chassis or frame to an engine accessory
mounting bolt (such as an alternator mounting bracket bolt) or to the same engine bolt that the
manufacturer uses for the negative battery cable.
WARNING: Never ground the negative battery post of the battery directly to the vehicle frame.
Never install a ground under any bolt unless you are sure the bolt connects to the
engine block. Be sure the bolt does not have a critical mechanical function.
The head gasket of an engine may fail and severely damage the engine if a soft lug or washer is placed
under a head bolt. Bolts can NOT be properly torqued against the soft materials used in electrical lugs.

Frame-Type Vehicles

Vehicles with frames often have rubber body mounts that insulate the body from the frame. The vehicle
designers do this to minimize noise, vibration and harshness. The bodies of vehicles that use insulating
body mounts must have flexible strapping connected between the body and the frame at all four corners
of the body. This includes pick-up truck beds.
