5. length Use 4 gauge wire Connect the remote terminal to the remote output of the head unit using 14 gauge Connect an empty fuse holder within 300mm 12 of the battery and 4 gauge or larger high quality cable from this fuse to the amplifier location Make sure there is no fuse in this fuse holder Then make the connection to the BATT connection on the amplifier If multiple amplifiers are being used use cables each with its own fuse at the battery or a 0 or a 2 cable from the fuse holder at the battery to a distribution block at or near the amplifier s location Connect all line inputs and outputs using high quality RCA RCA cables Insert fuse s at the battery fuse holder s Recheck all connections before powering up Set all level controls to their least sensitive positions and set all crossover controls switches etc To the desired frequency or position Once the system is powered up set the volume control on the head unit to about the 2 o clock position and then set all the amplifiers level controls for maximum output level Further fine tuning of the various controls may be necessary to obtain the desired results troubleshooting Before removing your amplifier refer to the list below and follow the suggested procedures Always test the speaker 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
6. 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 units 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 always caused by a poorly grounded RCA patch cord
