occur, and reduce slightly from this point.

low level inputs this amp features gold-plated RCA input

jacks for high impedance input. Use these

with car stereo output which uses RCA-type

connector cables.

speaker connections these terminals are 14K gold plated to

guarantee high conductivity and minimum

signal loss.

treble control use this control to adjust the treble output level

to suit your taste or audio program material.

electrical system from short circuit conditions.

power terminals use these connectors to deliver power, ground,

and remote turn-on control to the amplifier.

2 ch amp PB444X • PB446X • PB449X•4champPB448X

Please read the Installation Precautions section below before installing

your Pyramid Super Blue amplifier, and then refer to the diagrams

provided to connect power, audio input and speaker connections

according to your own system configuration requirements.

Installation Precautions

• Before you drill or cut any holes, investigate your car’s layout

very carefully. Take care when you work near the gas tank,

fuel lines, hydraulic line and electrical wiring.

• Do not operate the amplifier when it is unmounted. Attach

all audio system components securely within the automobile

to prevent damage, especially in an accident.

• Do not mount this amplifier so that the wire connections are

unprotected or in a pinched condition, or likely to be damaged

by nearby objects. Be sure to select a location inside your

vehicle which has adequate ventilation.

• Before making or breaking power connections in your system,

disconnect the vehicle battery. Confirm that your head unit or

other equipment is turned off while connecting the input jacks

and speaker terminals.

• If you need to replace the power fuse, only replace it with

a fuse identical to that supplied with the system. Using a fuse

of a different type or rating may result in damage to your

system which isn’t covered by the manufacturer’s warranty.
