DMP66/DMP660 INSTALLATION
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.
Getting Started
• Determine where the speakers will be mounted. Ensure an area large enough for
the speaker to mount evenly. Be sure the mounting location is deep enough for the
speaker to fit.
• Using an appropriate tool, cut a 5.13" diameter mounting hole.
• Use the speaker as a template to mark the locations for the mounting screws. Drill
the holes with a 3/32" bit. Route speaker wires and connect to speakers, observing
speaker polarity.
• Install speaker into opening using supplied hardware and test for correct operation.
