• Check that remote DC terminal has at least +12v 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) inspeakers. • 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 ispowered 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 are 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. STOP YES! NO! 2-channel Amplifier (Operating in Stereo) 4 ohm 4 ohm Two 4-ohm speakers, wired in stereo, will present a 4-ohm load to each channel of the amplifier. Most two-channel amplifiers will work well in this configuration. Two 4-ohm speakers, wired in parallel to a bridged two-channel amplifier. will present a 2-ohm mono load to the amplifier.
