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.

Always test the speakers and their wires first. Amplifier will not power up. • Check for good ground connection. • Check that remote DC terminal has at least +3v DC. • Check that there is battery power on the + terminal. • Check all fuses. • Check that Protection LED is not lit. If it is lit, shut off amplifier briefly and then repower it. High hiss or engine noise (alternator whine) in speakers. • Disconnect all RCA inputs to the amplifier(s) – if hiss/noise disappears, then plug in the component driving the amplifier and unplug its inputs. If hiss/noise disappears, go on until the faulty/noisy component is found. • It is best to set the amplifier's input level as insensitive as possible. The best subjective S/N ratio is obtainable this way. Try to drive as high a signal level from the head unit as possible. Protection LED comes on when the amplifier is powered up. • Check for shorts on speaker leads. • Check that the volume control on the head unit is turned down low. • Remove speaker leads, and reset the amplifier. If the Protection LED still comes on, then the amplifier is faulty. Amplifier(s) gets very hot. • Check that the minimum speaker impedance for that model is correct. • Check for speaker shorts. • Check that there is good airflow around the amplifier. In some applications, an external cooling fan may be required. Distorted sound • Check that the Level control(s) is set to match the signal level of the head unit. • Check that all crossover frequencies have been properly set. • Check for shorts on the speaker leads. High squeal noise from speakers. • This is almost always caused by a poorly-grounded RCA patch cord. 13 MANUFACTURER’S LIMITED TWO YEAR WARRANTY PYRAMID SOUND CORP. warrants this unit to be free from defective material or workmanship and will repair or replace this unit or any part thereof if it proves defective in normal use or service within two (2) years from the date of original purchase.
