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.
