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.

Mitek Mobile Limited Warranty
Our Guarantee
Mitek Mobile products (including MTX, Streetwires, Coustic and Magnum) purchased in the USA after
1/1/2013 from an authorized Mitek retailer are guaranteed to be free from material defects in products
and workmanship for five (5) years to the original end user purchaser, subject to the terms and conditions
below.
Length of Limited Warranty and Remedy
The warranty period begins the day the product is purchased by the end user, and is limited to the original
retail purchaser of the product.
Free Replacement Period (2 Years)
Products found to be defective in materials or workmanship during the first 2 years will be, at Mitek's
option, repaired or replaced by Mitek at no charge. When a product is replaced during first 2 years, the
warranty does not renew, it continues on from the original date of purchase.
Proration Period (Years 3-5)
The prorated purchase price of any product which becomes defective after the first two years and prior to
the end of the warranty period may be credited toward the purchase of a new Mitek product. The amount
of the proration shall be determined by dividing the purchase price by the number of months of the
warranty period (60), and then multiplying the result by the number of months remaining in the warranty
period. Any partial months will be rounded to the nearest whole month. For example, a product purchased
37 months ago for $100 would be calculated by dividing $100 by 60 months = $1.66/month, multiplied by
23 (the months remaining in the warranty period) for a prorated warranty amount of $38.33.
You are responsible for all costs for removal, reinstallation and proper packaging, shipping, insurance or
other freight charges incurred in the shipment of the product or part to Mitek. Mitek will ship the repaired
or replaced Mitek product or replacement parts to you at no charge. Mitek reserves the right to utilize
reconditioned, refurbished, repaired or remanufactured products or parts in the warranty repair or
replacement process. Such products and parts will be comparable in function and performance to an
original product or part and warranted for the remainder of the original warranty period.
What Is Not Covered
This warranty does not cover the product if it has been subject to neglect, abuse, misuse, incorrect
connection, or if it has been subject to unauthorized repair or alterations of any nature, or if the serial
number has been altered or removed, and the warranty does not extend to cosmetics or finish. This
warranty only applies to products installed and used in the USA.
What You Must Do to Obtain Warranty Service
You must contact Mitek Warranty via our website at MTX.com, or via email at
mitekwarranty@mitekusa.com, or by calling 800-556-2888. If you did not purchase the product directly from
Mitek, a proof of purchase must be provided in order to receive warranty consideration. You will be issued
a Return Authorization (RA) number which must be written on the outside of the package before returning
the product to Mitek.
No Other Warranties
THE LIMITED WARRANTIES DESCRIBED ABOVE ARE EXCLUSIVE AND IN LIEU OF ANY OTHER
WARRANTIES, EXPRESS OR IMPLIED. MITEK DISCLAIMS AND EXCLUDES ALL OTHER EXPRESS
WARRANTIES, AND DISCLAIMS AND EXCLUDES ALL WARRANTIES IMPLIED BY LAW, INCLUDING
WITHOUT LIMITATION THOSE OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. TO THE EXTENT THAT APPLICABLE LAW PROHIBITS THE EXCLUSION OF IMPLIED
WARRANTIES, THE DURATION OF ANY APPLICABLE IMPLIED WARRANTY IS LIMITED TO THE
PERIOD SPECIFIED FOR THE EXPRESS WARRANTY. Some states do not allow limitations on how
long an implied warranty lasts, so the above limitation may not apply to you. Any oral or written
description of any Mitek product is for the sole purpose of identifying it and shall not be construed as an
express warranty.
Limitation of Liability
MITEK'S OBLIGATION TO PROVIDE A CREDIT, OR REPAIR OR REPLACE AT MITEK'S OPTION,
SHALL BE YOUR SOLE AND EXCLUSIVE REMEDY UNDER THIS LIMITED WARRANTY AND
MITEK'S SOLE AND EXCLUSIVE OBLIGATION. MITEK SHALL NOT BE LIABLE FOR INCIDENTAL,
INDIRECT, CONSEQUENTIAL OR SPECIAL DAMAGES ARISING OUT OF OR IN CONNECTION WITH
THE MITEK PRODUCT, ITS USE OR PERFORMANCE. Incidental damages include, but are not limited
to, such damages as loss of time and loss of use. Consequential damages include, but are not limited to,
the cost of repairing or replacing other property which was damaged if the Mitek product does not work
properly.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. This warranty gives you specific legal rights, and you may
also have other rights, which vary from state to state. This limited warranty supersedes all prior warranties
and is not transferable from the original consumer purchaser.
Any assistance Mitek provides to or procures for you outside the terms, limitations or exclusions of this
limited warranty will not constitute a waiver of such terms, limitations or exclusions, nor will such
assistance extend or revive the warranty. Mitek will not reimburse you for any expenses incurred by you
