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 - In the channel on driver side threshold, locate the left rear speaker wires wrapped in black
tape. Wire colors for the left rear speakers are; tan / yellow (positive) and gray / light blue (negative).
In the channel on the passenger side threshold, locate the right rear speaker wires. Right rear
speaker wire colors are; orange / red (positive) and brown / pink (negative). Tap into wires and route
over to passenger side threshold and to pre-amp on 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.
