INSTALLATION ...... » PRE
-1. Find a suitable location in the vehicle to mount the amplifier.
2. Make sure there is sufficient air flow around the intended mounting location.
3. Bolt the amplifier to the mounting surface.
4. Counect the power ground terminal to the nearest point on the cl1assis of the car. Keep this ground wire less than one meter (39") in length. Use 8 gauge wire.
5. Counect the remote terminal to the remote output of the head unit using 14 gauge wire.
6. Counect an empty fuse holder within 300 mm (12") of the battery and run 8 gauge or larger high quality cable from this fuse to the amplifier location.
7. Make sure there is no fuse in this fuse holder. Then make the connection to the "BATf" connection on the amplifier.
8. If multiple amplifiers are being used, use cables (eacll with its own fuse at the battery) or a #0 or #2 cable from the fuse holder at the battery to a distribution block at or near the amplifier's location.
9. Connect all line inputs and outputs using high-quality RCA-RCA cables.
10. Iusert fuse(s) at the batteryfuseholder(s).
11. Recheck all connectious before powering up.
12. Set all level controls to their least sensitive positions and set all crossover controls, switcl1es, etc. to the desired frequency or position.
13. 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.
14. Further fine tuning of the various controls may be necessary to obtain the desired results.
• Before you drill or cut any holes, investigate your car's layout veIY carefully. Take care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring.
• Do not operate the amplifier when it is unmounted. Attach all audio system components securelywithin the automobile to prevent damage, especially in an accident.
• Do not mount this amplifier so that the wire connections are unprotected or in a pinched condition, or likely to be damaged by nearby objects. Be sure to select a location inside your vehicle which has adequate ventilation.
• Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off wbile connecting the input jacks and speaker terminals.
• If you need to replace the power fuse, only replace it with a fuse identical to that supplied with the system. Using a fuse of a different type or rating may resnlt in damage to your system which isn't covered by the manufacturer's warranty.

AMPLIFIER WILL NOT POWER UP.
• Check for good ground connection. • Check that remote DC terminal has at least 3v 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) - ifhiss/noise disappears, then plug in the component driving the amplifier and unplug its inputs. Ifhiss/noise disappears, go on until the faulty/noisy component is found.
• It is best to set the amplifier's input level as low as possible. The best subjective SIN 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 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 have been 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.
