Planning your power connections
The power end plates of the Zapco AP amplifiers carry the power connections and the
speaker connections and vary somewhat by the number of channels. One model, the
Z-150.2 AP has on-board fuses, while all other models will require an in-line fuse. The main
12-volt power input, the 12-volt turn-on wire, and the main Ground connections are
common to all models.
• The connection at the interior of the end plate is the main power input.
This must be connected the vehicle battery's positive (+) terminal, and a
main system fuse should be placed close to the battery.
• The connection at the outside of the end plate is the main ground or negative
connection. This must be securely attached to bare metal at the vehicle frame,
or other heavy chassis component with a direct connection to the frame.
Note: Seat bolts and seat belt bolts are NOT good ground points
• The small terminal between the main power and ground is the +12
turn-on input and can be connected to the head unit turn-on output wire.
If none is available it can be connected to an accessory (ACC) terminal.
You should avoid using any ignition-on (IGN) wire, as they can be noisy.
Note: The Z-Series AP amplifiers have terminals that do not require connectors. You simply insert a bare portion
of wire and tighten the connection. As the wire conforms to the connector the connection can loosen. You
should re-tighten the connection after about a week.
