Alphasonik PM12005E Manuale Utente

Before beginning the installation, consider the following:        

A. If you plan to expand your system by adding other components sometimes in 

the future, ensure that adequate is left, and cooling requirements are met.         

B. Are your components matched? The peak power rating of your speakers 

must be equal or greater than the amplifier’s. They also must be 2-8 ohms im-

pedance (This information is normally printed on the speaker magnet).        

C. Consider the length of your leads which should not be too long or short when 

determining the mounting location. Pre-Amp input jacks require a length of high 

quality shielded male to male RCA patch cord.  

      

        

Mounting Your Amplifier        

The mounting position of your amplifier will have a greater affect on its ability to 

dissipate the heat generated during normal operation. This amplifier has ample 

heat sink for heat dissipation, and is designed with a thermal shutdown circuit 

(for heat protection). DO NOT enclose the amplifier in a small box or cover it so 

that air is not able to flow freely.        

        

Temperatures in car trunks have been measured as high as (155 F) in the sum-

mer time. As the thermal shut down point for the amplifier is (185 F), it is easy 

to see that it must be mounted in an area that provides for maximum cooling 

capability. To achieve maximum advantage of convection air flow in an enclosed 

trunk, mount the amplifier in a horizontal position.        

        

Cooling requirements are considerably relaxed when the mounting inside the 

passenger compartment since the driver compartment will not allow tempera-

tures to reach a critical point. Floor mounting under the seat is usually satisfac-

tory as long as there is at least 1 inch of clearance above the amplifier’s heat 

sink for ventilation.        

        

A. Select a suitable location that is convenient for mounting, is accessible for 

wiring, and has ample room for air circulation and cooling.        

B. Use the amplifier as a template to mark the mounting holes. Remove the am-

plifier and drill holes. Use extreme caution, inspect underneath surface before 

drilling!        

C. Secure the amplifier using the screws provided.        

        

Caution: Before connecting any wires to the amplifier, discon-

nect the ground lead from the battery. Leave the ground lead                                                                      

disconnected until you are done wiring the amplifier.
