o(+12V) PowerTerminal -This
is
the main power
input
for the amplifier and
must be connected directly
to
the
positive terminal
of
the vehicles battery
for proper operation.
Use
caution when installing
(+
12V) power cable in
the vehicle. Avoid running this cable parallel
with
RCA
cables, antennas, or
other sensitive equipment due
to
massive currents
that
can
induce noise
into
the
audio system.
It
is
also very
important
to
have atight, secure con-
nection for maximum performance.
MTX
recommends using a
minimum
of
6mm
2full copper power wire
with
the
MTX
RT8PT
powered tube.
oRemote
Terminal-
The powered tube
can
be turned on by applying
12
volts
to
this terminal. Typically this voltage
is
supplied by awire from the source
unit
marked"remote"or"power antenna':
.])
Ground Terminal - A proper ground
is
required for your amplifier
to
operate at peak performance. Ashort ground
cable
the
same diameter
as
the powercable should be used
to
attach the ground terminal directly to the
chassis
of
the
vehicle. Always remove paint,
dirt
or debris
to
expose bare metal where the ground will be attached.
'1)
Fuses
-When the fuse blows, replace
it
with
the same value. The
RT8PT
uses
a20A fuse.
Caution: Never use ahigher rated fuse!
Installation &Mounting ••
MTX
recommends your new
RoadTHUNDER
powered
tube
to
be installed by
an
Authorized
MTX
retailer. Any deviation
from specified installation instructions
can
cause serious damage
to
the amplifier, speakers
and/or
vehicles electrical
system. Damage caused from improper installation
is
NOT
covered under warranty.
Please
verify all connections prior
to
turn
on your system!
1.
Disconnect the vehicle's negative battery cable.
2.
Determine the
mounting
place foryour
MTX
powered enclosure. Hook
it
with
the
provided belts. Keep in mind there
should be sufficient air flow for proper cooling.
3.
Install apositive (+) powercable from the vehicle's battery
through
the
firewall using a
grommet
orfirewall 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
(8).
Do Not connect
to
the
battery at this time.
Note:
Use
only proper gauge wire for
both
positive and negative connections.
4.
Install acircuit breaker or fuse
within
20cm
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 circuitbreaker
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 aproperground
point
on thevehicle's chassis and remove all paint,
dirt
ordebris
to
reveal abare
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
(10).
6.
Connect aremote turn-on wire from
the
source
unit
to
the
powered
tube
remote terminal
(9).
If
the source
unit
does
not
have adedicated RemoteTurn-on lead, you may connect
to
the source unit's Power Antenna lead.
7.
Connecting signal cables
to
the
amplifier:There are
two
ways
to
supply the signal
to
your
MTX
powered tube.
•
To
get
maximum performance, we suggestconnecting ahigh quality
RCA
to
the corresponding outputs at the source
unit
and inputs
of
the amplifier.
·If
asource
unit
is
being used
without
RCA
outputs,
use
the included high-level amplifier's speaker terminals
(1)
using
the
right
gauge speaker wire.
8. Double check all previous installation steps, in particular, wiring and component connections. Once verified, recon-
nect
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 way
down
(counter clockwise) before proceeding
with
adjustments.
