Step 15 - Ground amplier 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 16 - Connect remote (Blue) wire to 12-volt switched accessory. To turn on the amplier 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 17 - In the channel on driver side threshold, locate the left and right rear speaker wires.
Wire colors for the left rear speakers are; dark green / dark blue (positive) and dark green / purple
(negative). The right rear speaker wire colors are; gray / dark blue (positive) and gray / tan (negative).
Tap into wires and route under the carpet 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 verication is required.
