Mounting Your Z-Series Ap Amplifier - zapco Z-150.2 AP Owner's Manual

Note: It takes lots of current to make lots of power!
Remember! An electrical circuit is just that... a complete circuit. For current to travel, you
must complete the circuit from the positive terminal to the negative terminal (which is
connected to the vehicle frame). So what ever Gauge wire you use for power (B+) you
must also use for ground (B-).
Note: A 4-gauge power wire needs 4-gauge ground wire!
Use the Wire Sizing Chart! Add up the fuse values on the amplifier(s) then choose the
proper size wire based on the distance from the car battery to the amplifier location.
Again, always use the same gauge wire for the main ground as you do for the main power.
Always make your ground as short as possible and secure it to a clean solid surface,
preferably the vehicle frame.
Mounting your Zapco amplifier is easy. Just keep in mind a few guidelines:
• The amplifier can be mounted in any direction, on wood, metal, or carpet
• The metal chassis of the amp can be grounded or left isolated
• The amplifier requires adequate ventilation. Creating power creates
heat, and cooling requires air. Position the amplifier with sufficient
surrounding area for air supply and keep the end plate and side vents
clear for internal cooling
• Keep the amplifier out of the engine compartment or other locations
that may cause excessive heat or moisture
• Do not mount the amplifier to a subwoofer box or other place that may
have excessive vibration
Setting Gains: Gain pots are not volume controls. Before you first turn on your system,
you should make sure all gain controls are set to minimum. Gain controls should be used
only if absolutely necessary. Turning up gain controls causes increased noise, makes
distortion more likely and reduces the dynamic range of your system. If you head unit
does not have sufficient output, you will get much better results by investing in a line
driver to provide more signal to the amplifier.
