FINAL INSTALLATION
Proper installation of your amplifier should also address several areas; adequate mounting and
ventilation, proper signal input interface, correct use of internal crossover networks, "clean"
power/ground wiring, proper fusing, and power/speaker wiring.
ADEQUATE MOUNTING AND VENTILATION
Inevitably this amplifier will be mounted in locations with limited space.
amplifier on a vertical surface with the fins up/down for best vertical air movement. The mounting
screws supplied with this unit should be used for the most secure installation.
SIGNAL INPUT INTERFACE
This amplifier can accept input signals up to 6 volts rms over the RCA input jacks.
signal capabilities, people may want to interface the high level output of a radio (24 Vrms) to the input
of the amplifier. This can be easily done by connecting the "+" lines of the two speaker outputs to the
center conductors of the RCA jacks. One common signal ground reference wire is connected from the
radio chassis to the shields of the RCA lines connecting to the amplifier input.
