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 13.8v 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. X anzar Vibe Owner’s Manual - 11 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 maybe required. Distorted sound Check thatthe Level control(s) isset to match thesignal level of the head unit. Check thatall crossover frequencies havebeen properlyset. Check forshorts on the speaker leads. High squeal noise from speakers.
