IMPORTANT NOTICE
Whenever working on the vehicle, it is recommended to disconnect the battery prior to starting work.
Failure to do so may lead to a risk of electric shock or equipment damage.
When connecting power and ground wires ensure that the red power wire is fused at the point
where it is connected to the vehicle’s battery. Failure to do so can result in damage to the vehicle if a
short circuit develops between the vehicle connection point and the product.

Step 7 - Drill a hole through the rewall. Locate a spot low on the rewall on the driver side. You
should always look to nd a clear path. Drill a hole from inside of the vehicle into engine compartment
and insert grommet. In this location you may also nd a pre-existing rubber grommet to run the wire
through. Note: To avoid any damage to parts inside engine compartment, drill from inside of vehicle
using a short bit.
Step 8 - Route 10ga red power wire through grommet into the engine compartment.
Step 9 - Route 10ga red power wire through engine compartment safely away from any moving or hot
parts that could damage the wire.
Step 10 - Cut 10ga red power wire to length, connect the supplied fuse holder from the wire kit to the
end of the wire.
Step 11 - Remove 20 amp fuse from supplied fuse holder. Connect furnished ring terminal to positive
side of battery. Remove 10mm bolt from factory battery terminal. Pass bolt through factory battery
terminal, then ring terminal, and into the other side of factory battery terminal and retighten bolt.
Note: Always turn the ignition OFF when connecting or disconnecting battery cables. Failing to do so
may damage electronic components.
Step 12 - 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 13 - 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 14 - You can nd the factory speaker wires on the driver side of the truck under the threshold
trim removed in Step 3. The wire colors for the left channel are; tan / yellow (positive) and gray / light
blue (negative). The wire colors for the right channel are; orange / red (positive) and brown / pink
(negative). Tap into wires and route over to passenger side threshold 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 verication is required.

Step 15 - Plug power wire harness into amplier pre-amp.
Step 16 - Replace 20 amp fuse under hood.
Step 17 - When amp turns on, LED will display red during diagnostic mode, and then green, signaling
amp is on and functioning. Amp will only turn on when radio is on.
Step 18 - Adjust gain.
Setting Gain
Turn gain knob on ThunderForm pre-amp to minimum, counter clockwise. Play a favorite song that
contains consistent music and bass. Turn the source unit to maximum listening level. You should
know that some source units will produce distortion or “clip” before the unit reaches maximum
volume. Reduce volume to the loudest listening level before distortion. Turn the gain knob on the
ThunderForm pre-amp clockwise until the speaker starts to distort and reduce gain to loudest
listening level before distortion.
Optional - The EBC, or Electronic Bass Control, allows a remote bass control to be adjusted from the
driver’s seat.
Troubleshooting Tips if Amp Does Not Turn On
• Check all connections at battery and that fuse is installed
• Check speaker wire connections
• Check ground
• Check fuse on pre-amp
