contained within this manual is accurate, please be aware that any
part of it is subject to change without notice.
The following instructions should be used a general
guideline only. If you are unsure about performing
any of the procedures listed below, please consult a
professional car audio installation center.
Before installation, please follow these guidelines:
1. Be sure to carefully read and understand the instructions before
attempting to install this product.
2. For safety, disconnect the negative terminal from the battery
prior to beginning the installation.
3. Use the highest quality connectors for a reliable installation and
to minimize signal or power loss.
4. Use caution before you drill or cut! 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.
5. Never run speaker wires underneath your vehicle. Running
speaker wires inside the vehicle provides the best protection
from exhaust heat and environmental elements.
6. Avoid running wires over, near, or through sharp edged surfaces.
Use rubber grommets to protect any wires routed through metal.
7. When running the speaker cable from the amplifier, avoid
running it near sources of high current (i.e. wiring harnesses,
battery cables).
