Power Connections - B52 marine BMP 4004 Instruction Manual

INSTALLATION

POWER CONNECTIONS

The B52 marine amplifiers are capable of delivering extremely high power levels, and require
a heavy-duty and reliable connection to the vehicle's electrical system in order to perform
optimally. Please adhere to the following instructions carefully:
Ground Connection
Connect the amplifier's Ground(GND) terminal to a solid point on the vessel metal chassis, as
close to the amplifier as possible. Refer to the chart below to determine minimum wire-gauge
size. Scrape away any paint from this location; use a star-type lock washer to secure the
connection.
Power Connection
Connect a wire (see chart at right for appropriate gauge) directly to the vehicle's positive battery
terminal, and install an appropriate fuse holder with in 18" of the battery terminal. Do not install
the fuse at this time. Route the wire to the amplifier's location, and connect it to the amplifier's
Positive (BATT+) terminal. Be sure to use appropriate grommets whenever routing wires through
the firewall or other sheet metal. Failure to adequately protect the positive wire from potential
damage may result in a vehicle fire. When you are done routing and connecting this wire, you
may install the fuse at the battery.
Remote connection
Connect the amplifier's Remote (REM) terminal to the source unit's Remote Turn On lead using a
minimum of 18-gauge wire.
Speaker Connections
Refer to the application guides on the pages that follow. Speaker connections should be made
using a wire as per the following chart instructions.
