INSTRL.L.RTION
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 amplifierto the mounting surface.
4. Connect the powerground terminal to the nearest pointon the chassis
of the car.
Keep this 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. Connectan empty fuse holderwithin
300 mm (12") of the batteryand run 8 gauge
or larger high qualitycable from this fuse to the amplifierlocation.
7. Make sure there is no fuse in this fuse holder. Then make the connection to the
"BATT"connection on the amplifier.
8. If multiple amplifiers are being used, use cables (each with it's own fuse atthe
battery)ora # 0
or #2 cable from the fuse holderatthe battery to a distribution
blockat
or nearthe amplifier's location.
9. Connectall line inputs and outputs using high-quality RCA-RCAcables.
10. Insertfusees) at the batteryfuse holder(s).
11. Recheck all connections before powering up.
12. Setall level controls to their least 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 unitto about
the 2 O'clock position, and then setall the amplifiers' level controls
for maximum
output level.
14. Furtherfine tuning
of the various controls may be mlnecessaryto obtain
the desired results.
P"'EC:RUTIONS
1. Before you drill or cut any holes, investigate your car's layoutvery carefully.
Take care when uwork nearthe gas tank, fuel lines, hydraulic lines and electrical
wiring ..
2. Do notoperate the amplifierwhen it is unmounted. Attach all audio system
components securelywithin the automobile to prevent damage, especially in an
accident
3. Do not mountthis amplifierso that the wire connections are unprotected
or in a
pinched condition,
or likelyto be damaged by nearby objects. Be sure to select a
location inside
your vehicle which has adequate ventilation ..
4. Before making or breaking powerconnections in your system, disconnectthe
vehicle battery. Confirm
that your head unit or otherequipment is turned off while
connecting the input
jacks and speakerterminals.
5. Ifyou need to replace the powerfuse,
only replace itwith a fuse identical to that
supplied with the system. Using a fuse fo a differenttype or rating may result in
damage to your system which isn'tcovered bythe manufacturer's warranty.

TROUBL.ESHOOTING
TROUBL.ESHOOTING
Amplifier will not power up.
• Check for good ground connection.
• Checkthat remote DC terminal has at least 3V DC.
• Checkthat there is battery power
on the + terminal.
• Check all fuses.
• Checkthat Protection LED is notlit.
If it is lit, shut off amplifierbrieflyand
then repower it.
High hiss or engine noise (alternator whine) in speakers.
• Disconnectall RCAinputs to the amplifier(s)-ifhiss/noise disappears, then
plug in the component driving the amplifierand unplug it's inputs. If
hissl
noisedisappears, 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 unitas possible.
Protection LED comes on when the amplifier Is powered up.
• Check for shortson speaker leads.
• Checkthat the volume control
on the head unitis turned down low.
• Remove speakerleads, and resetthe amplifier.
If the Protection LED still
comes on, then the amplifier is faulty.
Amplifier(s) gets very hot.
• Checkthat the minimum speaker impedance for that model is correct.
• Check
for speakershorts.
• Checkthat there is good airflow around the amplifier.
In some applications,
an external cooling fan many be required.
Distorted Sound
• Checkthat the Level control(s) is set to match the signal level olthe head unit.
• Checkthat all crossoverfrequencies have been properly set.
• Check
for shortson the speakerleads.
High squeal noise from speakers.
• This is almost always caused by a poorly-grounded RCA patch cord.
