2. The heat sink of your amplifier is designed to act as a noise shield. To
maintain this protection, be sure the metal case of the amplifier does not touch
any metal in the car. Do not remove or damage the rubber grommets that provide
electrical insulation and vibration isolation. Avoid mounting the amplifier in the
dash or on the firewall where sources of noise such as your alternator,
windshield wiper motor, and air conditioner radiate the most energy.
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 V dc on the +12 V and REM inputs and check for a solid
ground connection on the power connector. If yellow thermal LED or red
current LED is 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 the
input level control for proper setting. Check for proper speaker impedance!
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.
