INSTALLATION

Step 1 – Slide front seats to the full forward position and fold-up rear seats. This will give you more room to work with.

Step 2 – Remove jack tools from the floor and set them aside (you will reinstall them later in Step 23). The jack does not need to be removed and stays in the factory location.

Step 3 – You may want someone to help you with this step. Lift enclosure into your truck and place it on the floor behind the front seats with the woofers facing up.

Step 4 – If externally amplified, make speaker connections to the enclosure from the amplifier.
Connect speaker wires from amplifier to enclosure, positive to the red terminal and negative to the black terminal.

Amplified ThunderForm
Note: When routing power wire we recommend a connection directly to the battery.
Step 5 – Remove driver side and passenger side threshold trim; pull up on trim, it will remove easily.

Step 6 – Using furnished wiring harness route 10ga red power wire starting at pre-amp location.
Route wire on driver’s side, over to threshold, and under the carpet to the front of the vehicle.

Step 7 – Open hood.

Step 8 – Drill a hole through the firewall. Locate a spot low on the firewall on the passenger side.
You should always look to find a clear path. Drill a hole from the inside of the vehicle into the engine compartment and insert the 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 the engine compartment, drill from inside of the vehicle using a short it.
Step 9 – Route 10ga red power wire through the grommet into the engine compartment.

Step 10 – Route 10ga red power wire through engine compartment safely away from any moving or hot parts that could damage the wire.

Step 11 – Cut 10ga red power wire to length, connect the supplied fuse holder from the wire kit to the end of the wire.

Step 12 – Remove 20 amp fuse from MTX fuse holder. Connect furnished ring terminal to the positive side of the battery.

Remove 5 ⁄16″ bolt from the factory battery terminal. Place ring terminal on battery post and retighten the nut.
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 the vehicle; connect the terminal provided to the 10ga black wire from the 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 a remote (Blue) wire to the 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 the 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 the 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 sometimes occur.
If wiring colors do not match then physical verification is required.

Step 16 – Plug power wire harness into amplifier pre-amp.

Step 17 – Replace the 20 amp fuse under the hood.

Step 18 – When the amp turns on, LED will display red during the diagnostic mode, and then green, signaling
the amp is on and functioning. Amp will only turn on when the radio is on.

Step 19 – Adjust gain.

Setting Gain
Turn gain knob on ThunderForm pre-amp to a minimum, counterclockwise. 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 the battery and that fuse is installed
Check speaker wire connections
Check ground
Check the fuse on pre-amp

Step 20 – Reinstall threshold trim. Locate and align holes in the vehicle with pins on trim, and snap back into place.

Step 21 – Place the driver side of the enclosure in first, so it fits into the seat bracket. Then slide the passenger side, so the enclosure is tight against the seat bottom.

Step 22 – Using the supplied hardware, secure the enclosure to the floor of the vehicle as shown below.

Step 23 – Slide jack tools into a center compartment under the enclosure.
These instructions are guidelines only and in no way are intended to replace a professional installation.
As always before screwing or drilling check to make sure you will not damage any wires or hoses or cause damage to the vehicle.

Warning: Batteries normally produce explosive gases which can cause personal injury.
Therefore, do not allow flames, sparks, or lighted substances to come near the battery.
When charging or working near a battery, always shield your face and protect your eyes. Always provide ventilation.
