L 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 mowiting smface.

4. Connect the power ground terminal to the nearest point on the chassis of the car. Keepthis ground wire less than one meter (39") in length. Use 8 gauge wire.

5. Connect the remote terminal to the remote output of the head unit using 14 gauge wire.6. Connect an empty fuse bolder 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 "BATI'"connection on the amplifier.

8. If multiple amplifiers are being used, use cables (each with its own fuse at the battery)or a #O or #2 cable from the fuse bolder at the battery to a distribution block at or nearthe amplifier's location.

9. Connect all line inputs and outputs using high-quality RCA-RCA cables.

10. Insert fuse(s) at the batteryfuseholder(s).

u Recheck all connections before powering up. 12. Set all level controls to their lea.st sensitive positions and set all crossover controls,

switches, etc. to the desired frequency or position.

13. Once the system is powered up, set the volume control on the head unit to about the2 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 dn1l or cut any holes, investigate yourcar's layout very 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 unmOUDted.Attach all audio system components securelywithinthe automobile to prevent dam.age, especially in anaccident.

• Do not mount this amplifier so that the wireconnections are unprotected or in a pinchedcondition. or likely to be damaged by neaiby objects.Be sure to select a location inside yourvebicle whichhas adequate ventilation.

• Before making or breaking power connections in your system, dii;oonnectthe vehicle batteiy. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speakerterminals.

• If you need to replace the power fuse, only replaceit with a fuse identical to that supplied with thesystem. Using a fuse of a different type or ratingmay result in damage to your system which isn'tcovered by the manufacturer's warranty.

A MPLIFIER WILL NOT POWER UP.

• Check for good ground connection. • Check that remote DC terminal bas 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) - 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 amplifier1s input level as low 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 A MPLIFIER IS POWERED UP. • Check for shorts on speaker leads. • Check that the volume control on the bead unit is turned down low. • Remove speaker leads, and reset the amplifier. If the Protection LED still comes

on, then the amplifier is faulty.

AMPLlflER(S) GETS VERY HOT. • Check that the minimum speaker impedance for that mod.el 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

bead unit. • Check that all crossover frequencies have been properly set. • Check for shorts on the speaker leads.

HtGH SQUEAL NOISE FROM SPEAKERS. • This is almost always caused by a poorly-grounded RCA patch cord.
