INSTALLATION
AND
MOUNTING
MTX
recommends
your new
TD
Series
amplifier
be
installed
by
an
Authorized
MTX
retailer.
Any
deviation
from
specified installation instructions
can
cause
serious
damage
to
the
amplifier,
speakers
and/or vehicle's electrical
system.
Damage
caused
from
improper installation
is
NOT
covered
under
warranty.
Please
verify
all
connections prior
to
system
turn
on.
1.
Disconnect
the
vehicle's negative battery
cable.
2.
Determine
the
mounting
place
for your
MTX
amplifier.
Keep
in
mind
there
should
be
sufficient
air flow for proper cooling. Mark
the
mounting
holes
from
the
amplifier
to
be
drilled.Before
drilling
make
sure
all
vehicle wires,
gas
lines,
brake
lines
and
gas
tank
are
clear
and
will not
interfere with installation. Drill
the
desired
holes
and
mount
the
MTX
amplifier.
3.
Install a positive
(+)
power
cable
from
the
vehicle's battery through
the
firewall
using
agrommet
or
firewall
bushing
to
avoid
cable
damage
from
sharp
edges
of
the
firewall.
Run
the
cable
through
the
interior of
the
vehicle
and
connect it
to
the
amplifier's
(+
12V)
terminal.
Do
not connect
to
the
battery
at
this
time.
NOTE:
Use
only
proper
gauge
wire for
both
positive
and
negative connections.
4.
Install a circuit breaker
or
fuse
within
18
inches of
the
battery.
This
effectively lowers
the
risk
of
severe
damage
to
you
or
your
vehicle
in
case
of
ashort circuit
or
accident. Make
sure
the
circuit breaker
is
switched off
or
the
fuse
is
taken
out
of
the
fuse
holder untill
all
connections
are
made.
Now connect your positive power
cable
to
the
positive battery terminal of
the
battery.
5.
Grounding
-
Locate
a proper
ground
point
on
the
vehicle's
chassis
and
remove
all
paint,
dirt
or
debris
to
reveal
a
bare
metal
surface. Attach
the
ground
wire
to
that contact point.
Connect
the
opposite
end
of
the
ground
wire
to
the
(GND)
terminal
on
the
MTX
amplifier.
6.
Connect a
Remote
Turn-on
wire
from
the
source unit
to
the
MTX
amplifier's
(REM)
terminal. If
the
source unit
does
not
have
adedicated
Remote
Turn-on
lead,
you
may
connect to
the
source unit's
Power Antenna
lead.
7.
Supply
the
signal
to
your
MTX
amplifier
by
connecting
the
signal
cables
using
high
quality
RCA
to
the
corresponding outputs
at
the
source unit
and
inputs
of
the
amplifier.
8.
Connect your
speakers
to
your
MTX
amplifier's speaker terminals
using
the
correct
gauge
speaker wire.
Your
MTX
amp
can
drive a
2Q
(TD75.4
&
TD500.1
D)
and
1Q
(TD1000.1
D)
minimum
load
for
max
power.
9.
Double
check
all
previous installation
steps,
in
particular, wiring
and
component connections.
Once
verified, reconnect
the
vehicle's negative battery
cable,
turn
the
circuit breaker
on
or
place
the
fuse
in
the
fuse
holder.
NOTE:
Gain
Levels
on
the
amplifier
should
be
turned
all
the
