The Importance of Pre-Planning
This section focuses on some of the considerations for installing your new Diamond Audio amplier.
Pre-planning your audio system layout and best wiring routes will save installation time. When decid-
ing on the layout of your new components, be sure that each component will be easily accessible for
making adjustments.
CAUTION:
lf you feel unsure about installing this system yourself, have it installed by a qualied techni-
cian.
CAUTION: Before installation, disconnect the negative (-) battery terminal to prevent damage to the
unit, re and/or possible injury.
Before beginning any installation, follow these sensible guidelines:
1) Be sure to carefully read and understand the instructions before attempting to install the amplier.
The instructions can only help you make the installation successful.
2) For safety, disconnect the negative lead from the battery prior to beginning the installation. It will
keep any unintended short circuits from damaging vehicle electronics during installation of the
amplier.
3) For easier assembly, run all wires prior to mounting your amplier in place.
4) Route all of the RCA cables close together and away from any high current wires or vehicle com-
puters. This will greatly minimize the chances of unwanted noise.
5) Use high quality connectors for a reliable installation and to minimize signal or power loss.
6) Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic
lines, vacuum lines, or electrical wiring when working on any vehicle.
7) Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best
protection.
8) Avoid running wires over or through sharp edges. ALWAYS use rubber or plastic grommets to
protect any wires routed through metal, especially the rewall.
9) ALWAYS protect the battery and electrical system from damage with proper fusing. Install the ap-
propriate fuse holder and fuse on the +12V power wire within 18 inches (45.7 mm) of the positive
battery terminal. This is for protection of the wire running through the vehicle.
10) When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure a good,
clean ground connection. Grounding connections should be as short as possible, yet be adequately
connected to metal that is welded to the main body, or chassis of the vehicle. Do not use seat bolts,
trunk hinges, or poorly joined metal for grounding points.
