POWER CONNECTIONS
The amplifier requires a reliable 
connection to the boat’s electrical 
system in order to perform optimally. 
See Figures 1 and 2 for terminal con-
nection locations. Please adhere to 
the following instructions carefully: 

Ground Connection
Connect the amplifier’s Ground (GND) 
terminal to the battery’s negative terminal,
using a ring terminal. Refer to the wire gauge
chart to determine minimum wire gauge size. 

Power Connection
Connect a wire (see chart at right for
appropriate gauge) directly to the positive
battery terminal, and install an appropriate
fuse holder within 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 (+12V)
terminal. Be sure to use appropriate 
grommets whenever routing wires through
a bulkhead or other obstruction. Failure to
adequately protect the positive wire from
potential damage may result in a 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.

NOTE: If your source unit does not have 
a remote turn-on connection, connect 
the amplifier’s (REM) terminal to a wire
that provides +12V when the boat’s acces-
sories are on or when the key is switched
on. If no such circuit exists, install a
switch. See Figure 3.

Figure 3. Install a switch for the Remote
Turn-On lead.

Speaker Connections
Refer to the application guides on the
pages that follow. Speaker connections
should be made using a minimum of 
16-gauge wire.

These recommendations assume 10' – 12'
wire runs. If your amplifier will be mounted
farther than 12' from the boat’s battery, use
a larger gauge.

The MA6004 can be set up for stereo 
4-channel, 3-channel or bridged 
2-channel operation, as shown in
Figures 4 through 6. 

NOTE: For simplicity, Figures 4 through
6 do not show power, remote and input 
connections.

NOTE: Minimum speaker impedance
for stereo operation is 2 ohms.
Minimum speaker impedance for
bridged operation is 4 ohms.

to drive a set of full-range speakers and a subwoofer.
