" nut from factory battery terminal. Place ring terminal on battery post and

Note:
Always turn the ignition OFF when connecting or disconnecting battery cables.
Failing to do so may damage electronic components.
Step 13 - Ground amplifier to chassis of vehicle; connect the terminal provided to the 10ga black wire
from furnished wiring harness. A good ground is as important as the power connection. The ground
should be as short as possible and the contact point should be free of paint and debris.
Step 14 - Connect remote (Blue) wire to 12-volt switched accessory. To turn on the amplifier unit, a
switched 12-volt signal is required. Locate a 12-volt wire that is active when the vehicle key is on and
connect the blue remote wire to it. This may be found in the fuse panel, key-switch or radio harness.
Speaker Wires
Step 15 - Once the rear seat is pulled out, you will see the two main wire harnesses wrapped in black
tape (as shown bellow). Speaker wires are located on their respective sides and are twisted together
in these harnesses. Wire colors for the left rear speakers are; tan / yellow (positive) and
gray / light blue (negative). The right rear speaker wire colors are; orange / red (positive) and
brown / pink (negative). Tap into wires and route into the trunk, behind trunk liner and to pre-amp of
enclosure. Connect to the supplied High Level input harness wires and plug into the matching port on
the pre-amp.
Although, MTX has made every effort to assure proper wiring colors, MTX is not responsible for any
changes made by the vehicle manufacturer which sometime occur. If wiring colors do not match then
physical verification is required.
