Audio Equipment Installation

This kit includes a precut board and a set of determined mounting locations for the equipment. This board mounts all the audio equipment, including the Bose interface. It is designed to use the existing studs and nuts on the truck's back wall. This board also has a predetermined location for the inverter removed in the previous section.

Follow the steps below to install your audio equipment.

Equipment positions are marked on the board

Using the supplied screws, mount the amplifiers in place.

Using the provided hook-and-loop pad, secure the ETH1 DSP in place.

Using the supplied screws (smaller heads), mount the distribution block. The Vibe amplifiers are fused inside the amplifier case for added protection against short circuits.

With the amps and distribution block mounted, you will have two remaining screws; they will be used to mount the inverter.

If your seat-backs:

Wiring the Board

Connect the 16-pin connector into the ETH1 DSP and plug the RCAs into Amp1 and Amp2.

Using the provided 8GA Red power wire, connect to the distribution block and to the respective amplifiers.

The kits come with two different OE connectors that plug into the 8-pin connector on the ETH1 DSP.
Off each of these harnesses is an Orange and Black wire marked Bass Knob.

The LD-VB-ETHSPH will connect to the OE plugs removed from the factory Bose amplifier.

On both the LD-VB-ETH1 and LD-VB-ETH2, there is a 2-pin Molex connector with Yellow and Black wires. That 2-pin plug is connected to the mating connector on the LD-VB-ETHSPH harness.

When wiring the speakers using the LD-VB-ETHSPH, speaker wires are marked for which amp and the channel they need to be connected to on that amplifier. You will also have the Remote Wire to connect in this harness

Bass Knob Installation

To gain more bass response, you can choose between the two options below.

→ Bass Knob Installation: Option 1

In the OE radio, access the EQ Settings and add or remove any of the BASS, MIDRANGE or TREBLE levels.
With the radio on, find the SETTINGS icon (Fig A).

Fig A: Settings Menu

Choose AUDIO SETTINGS, and then EQUALIZER (Fig B).

Fig B

Amp 2

Mounting the Completed Amp Board

Bring the amp board to the vehicle, line up the OE studs, and slide the board into place.
Secure the board using the (3) OE 10mm nuts.

Plug in the OE connectors.

Using the supplied zip-ties, secure all wiring into bundles that will not interfere with the seat back mounting locations.

Wire Connections

Remove the jack from under the rear passenger seat to allow easier access to the floor for drilling the grommet location for the power wire.
Remove the wing nut and turn the RED knob on the jack to lower the piston and remove from the mount. There are (2) 10mm nuts that need to be removed to move the jack mount.

Pull the carpet back to expose the metal cab floor.

Locate the round plate found under the cab while running the power wire.

Using a Unibit, drill a hole to accommodate the 1" rubber grommet included in the kit.
Cut the grommet to allow the 4GA power wire to pass through.
Feed the power wire from under the vehicle into the cab of the vehicle through the grommet and toward the amp rack to connect to the distribution block.
Connect the 4GA power to the distribution block using a T-20 Torx.
Remove any excess length.

Remove (4) 7mm screws from the wire channel running along the rear door. This will provide a clear location to run the ground wires without interfering with any of the panels during reassembly.

Run the ground wires down the vehicle's passenger side and connect to the ground lug in the B-pillar using a 10mm ratchet.

Using the included zip ties for wire management, prepare the area for reassembly.

Final Steps

This kit includes a DSP tune specifically for this vehicle and the equipment. No additional programming or setup is required. Simply plug in and wire the equipment to complete the installation.

After connecting the speaker wires to the amplifier, the speaker wires must be connected to the terminal of the subwoofer.

Run the subwoofer speaker from the amp to under the driver side rear seat.

Place the enclosure under the seat and connect the speaker wires.

A jumper wire needs to be inserted into the terminal bridging VC1+ and VC2- (Fig A).

Fig A

Connect the positive wire from the amp to VC2+ (Fig B).
Connect the negative wire from the amp to VC1- (Fig B).

Fig B

Insert the wired terminal connector into the terminal on the subwoofer enclosure.

Connect the negative battery terminal back to the vehicle battery using a 10mm ratchet.

Testing the System

Turn the vehicle ignition On.
Ensure that your volume is at a low setting, but you should hear sound.
Select the Fade and Balance options on the radio. The system should fade and balance as normal:
Turn your left or right turn signals on. You should hear the turn signal clicks.

The door chime feature is also retained with the ETH DSP and should be audible.
Turn the ignition Off.
Exit the vehicle and ensure all doors and the hood are closed.
Lock the vehicle with the key fob and let it sit for 10 minutes.

After 10 minutes, unlock the vehicle.
Turn the ignition On.
Test to ensure audio is playing.

Reassembly

After a successful test of the system, you can begin to reassemble the back seat of the truck. Based on the model of your truck, you may have to modify the rear seat to allow reinstallation into the vehicle. Look over the instructions below to determine which steps to follow to reinstall the rear seat.

→ Back Seat With In-Seat Storage

Back Seat storage compartment

Back of seat with foam attached

Foam removed

Back seat with foam removed. Plastic shell remains and needs no more modification.

→ Back Seat Without In-Seat Storage

If your truck has a rear seat without in-seat storage:

Once you have cut enough foam to allow theseat to clear the amps on the amp board, you can install the seat back into the vehicle.

The white weather stripping can be removed, trimmed to length and reinstalled onto the modified seat foam.
Reinstall the (4) 10mm bolts to secure the back seat.
Move the seat belt anchor plate and buckle into place.Using a T-50 Torx, screw the retractor plate back in place and connect the electrical connector.

Install the (6) headrest mounts back in place, and install the headrests
Reinstall the trim pieces back on the passenger side, to include the B-pillar and front passenger door.
Reinstall the vehicle jack under the rear passenger seat.

The installation is complete!
