Before removing your amplifier, refer to the list below and follow the suggested procedures.
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 10V DC.
Check that there is battery power on the + terminal.
Check all FUSES.
Check that the protection LED is not lit. If it is lit, shut off amplifier briefly and then re-power
it.
HIGH HISS OR ENGINE NOISE (ALTERNATOR WHINE) IN SPEAKERS.
Disconnect all RCA inputs to the amplifier, if hiss/noise disappears, then plug in a compo-
nent driving the amplifier and un-plug it’s inputs. If hiss/ noise disappears, go on until the
faulty / noisy component is found. It is best to set the amplifier 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 shorted speaker leads.
Check that 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 will shut down automatically when the units’ temperature goes up to 80 C
O
this will protect the unit from damage.
AMPLIFIER GETS VERY HOT.
Check that the minimum speakers impedance for that model is correct.
Check for shorted speaker.
Check that there’s good airflow around the amplifier. In some applications, 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.
WARNING!
1. Excessive high volume will damage your speakers.
2. Be cautious when you use the amplifier near a gasoline tank and electrical wires.
3. Protect the connecting wires and parts to avoid any damage or short circuit.
4. The power must be connected through the terminal of the battery via a FUSE.
5. The sound system must be in turned off before you check the amplifier for issues.
6. Be sure that you use the same type of FUSE when you need to replace it.
* We reserve the right to make needed change or improvement to the product, without
informing customer about this in advance.
