HINTS ON INSTALLATION
- Always set the Mode switches before you adjust the frequency controls. The
frequency controls are used to further tailor the sound from your speakers.
- Make sure your signal cables are as far away as possible from any vehicle
electrical wiring, and as far away as possible from your speaker cables
- Make sure that all the components in your sound system are properly and
securely grounded. This will help reduce noise caused by "ground loops".
- Always make sure your amplifier(s) have plenty of air circulation to prevent
overheating. This will extend the life of the unit(s).

GENERAL TROUBLESHOOTING
No Sound: Check that the green power LED is on. If the green power indicator is
lit, check all signal input and speaker connections. If the green power LED is not
lit, check for +12 Vdc on +12 V and REM inputs and check for a solid ground
connection on power connector. If yellow thermal LED or red current LED are lit,
see the status indicators portion of this manual.
Blows Fuses: Check all connections to be sure all power wires do not touch
ground or each other. Be sure power connections are not reversed. Check
internal transformer configuration for proper setting. Check input level control for
proper setting.
Noise Problems: Be sure the metal sleeve on the RCA (phono) jacks does not
touch the metal chassis of the vehicle, the heat sink of the amp, or the chassis of
any other components in your installation. Route signal cables away from power
wires, power connections, speaker wires, engine alternator, and vehicle firewall.
