Preparation/Installation
Please read entire manual before installation.
Before You Start
• Disconnect negative battery terminal. Consult a qualified technician for instructions.
• Use extreme caution when drilling holes to avoid damaging fuel lines, hydraulic lines
or existing wiring.
• If additional wiring is required, we recommend that you run all wires prior to mounting
your speaker in place.
• Use the highest quality connectors for a reliable installation and to minimize signal and
power loss.
• Use caution before you drill or cut! Be careful not to cut or drill into gas tanks, fuel lines,
hydraulic lines, vacuum lines or electrical wiring.
• Avoid running wires over, near, or through sharp edged surfaces. We suggest you also
use rubber grommets to protect any wires routed through metal.
