Xtant M Series - Manual (Page 12)

M Series amplifiers are designed to operate from a car’s +12 volt, negative
ground electrical system. The power and ground cables should be a minimum of
8 gauge. Depending upon the complexity of your system, larger gauge wire may
be needed.
The main power cable should run from the amplifier location, through the vehi-
cle to the battery, avoiding sharp corners, creases, and sharp body parts. When
passing through any metal wall (i.e. fire wall etc.), a grommet must be used to
prevent the wire from chafing and shorting to ground.
The M Series amplifiers do not have an on-board fuse. An outboard fuse must
be installed in-line with the power wire within 12 inches of the battery. Use
the following fuse values at the battery: 121m and 202m: 30 Amp; 404m: 50
Amp. If multiple amps are being used, the fuse value should equal the com-
bined total demand of all amplifiers in the system.
A second outboard fuse may
be added close to the amplifier if desired. Consult your Authorized Xtant Dealer
for an appropriate in-line fuse holder that meets the needs of your installation.
We suggest crimping and soldering all wire connections. Insulate the connection
with heat shrink to prevent a short to ground.
The ground wire should be of the same gauge as the power
wire. As a 'rule of thumb', use as short a length of wire as
possible. Locate an area near the amplifier that is metal (the
floor or an existing unused threaded bolt hole is ideal) and
clean the area to bare metal. Drill a pilot hole (if necessary)
in the middle of this area. Be Careful! Inspect the area
underneath to be sure you aren’t drilling into wires, brake or
fuel lines, etc. Terminate the wire with a ring connector and
attach it to the bare metal. We suggest crimping and sol-
dering this connection. Insulate the connection with heat shrink. It is important
that this connection be solid. After the connection is complete, coat the area with
silicone or some similar material to prevent rust from developing.
Once the power and ground wires have been run, it’s time to connect the cable
to the amplifier. Be sure that you have not reconnected the ground cable to the
negative post of the battery. Cut off excess wire and terminate the wire with a
spade connector. We suggest crimping and soldering this connection. Insulate
the connection with heat shrink. Locate the power and ground connector. With
a small flat bladed or Philips head screw driver, loosen the terminal screws
marked: Ground and +12 Volts. Insert each spade connector and secure it by
tightening the associated screw. Be sure each connection is tight.
Remote Turn-On
In order for the amplifier to turn on, a remote turn-on wire must be connected
to a switched 12 volt source. Typically, the source unit provides a power
