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. 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. · Check that the minimum speaker impedance for that model is correct. · 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. · 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.
