INSTALLATION GUIDELINES (continued)

is generated. For low impedance

speaker applications or restricted

ventilation installations, an external

cooling fan may be advisable.

9. Your connections to the amplifier’s

speaker and power terminals

should be made with crimped

spade lugs, and the battery and

ground connections to the vehicle

should be made with crimped ring

terminals of the appropriate size

(surface area is what counts);

soldering the terminals after

crimping is also recommended.

10. Due to the high-frequency MOSFET

switching power supply used in all

Directed Audio amplifiers, filtering

the power cable is not generally

required (remember that the amp

can’t deliver full output if the power

supply is restricted). Proper

grounding of the signal source is

mandatory for the amplifier to

reach its performance peak. If the

RCA inputs are not grounded

adequately via the signal source,

electrical noise from the vehicle

may be picked up in the system.
