Drill a hole from inside of the vehicle into the engine compartment and insert grommet. You may also find a pre-existing, unused rubber grommet in this location that you can pass the wire through.

Note: To avoid any damage to parts inside engine compartment, drill from inside of vehicle using a short bit.

22. Using the supplied hardware, secure the enclosure to floor of vehicle and fold down rear seat as shown below.
14. 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.
As always, before screwing or drilling check to make sure you will not damage any wires, hoses or cause damage to the vehicle.

Factory Speaker Wire Colors

Wire colors for the left rear speakers are: Light Blue (positive) and Black w/Yellow (negative). The right rear speaker wire colors are: Orange w/Blue (positive) and Red w/Blue (negative). Tap into wires with the supplied RCA High Level input wires and route under the carpet to pre-amp of enclosure.
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. CONNECTION TO ENCLOSURE
