Honda Element Subwoofer Installation
- 1). Lift the Honda's hood and loosen the bolts that secure each of the battery cables to their respective battery terminals with a 10 mm wrench. Lift the negative battery cable from the battery terminal and set it aside. Lift the positive battery cable clamp from the battery. Place the ring terminal from the amplifier wiring kit onto the terminal post. Replace the positive battery cable clamp onto the terminal and tighten the bolt with the wrench.
- 2). Connect the power supply cable from the amp wiring kit to the ring terminal. Feed the cable into the passenger cabin through the opening in the firewall. Remove the fuse from the ring terminal.
- 3). Pry the trim panel surrounding the stereo assembly from the dashboard with a trim panel removal tool. Grab the panel, pull it from the dashboard and set it aside. Remove the four screws (two on each side) from the stereo bracket with a Phillips head screwdriver. Slide the factory stereo from the dashboard.
- 4). Disconnect the stereo wiring from the back of the Honda's stock stereo. Plug the two stereo wiring connectors into the wiring harness adapter leads. Plug the adapter's lead connectors into the outlets on the back of the stereo.
- 5). Plug the patch cables into the appropriately marked wiring harness adapter leads. Feed the patch cables through the back of the stereo mounting dock and down to the floor of the vehicle on the passenger's side. Replace the stereo into the stereo dock and install the four screws around the perimeter of the stereo bracket.
- 6). Route the power cable from the driver's side of the Honda to the rear cargo area of the vehicle. Run the patch cables along the passenger's side of the vehicle to the rear cargo area. Place the powered subwoofer in the back of the Element and connect the grounding wire (from the amp wiring kit) from the sub to a screw or bolt directly connected to the Honda's frame.
- 7). Plug the power cable into the power input on the sub. Connect the patch cables to the signal and turn-on lead outlets on the subwoofer.
- 8). Replace the negative battery cable clamp onto the negative battery terminal post. Tighten the cable's clamp to the terminal with the wrench. Place the fuse back into the fuse holder on the ring terminal and close the hood.
