CONNECTING THE POWER
CAUTION:
AS
A PRECAUTION, DISCONNECT THE POWER WIRE
FROM
THE BATTERY WHILE MAKING THE
POWER AND GROUND CONNECTIONS TO THE AMPLIFIER.
10
GAUGE(Thicker
if
planning for additional Amplifiers) wire
is
recommended for
both the power and ground wires.
10
Gauge, for the remote turn-on wire.
Both
types are available at most Mobile Audio Dealers or Installation Shop.
(1)
Ground:
To Vehicle Chassis
To avoid unwanted ignition noise caused by ground loop, it is essential that the
Amplifier
be
grounded to a clean, bare, metal surface
of
the vehicle's Chassis
NOTE:
GROUND WIRE SHOULD
NOT
BE
EXTENDED
MORE
THAN 3 FT.
(I
METER),
(2) +
12
Volt(Fused) Constant Power: To Battery (+)
Due to the power requirements
of
the Amplifier, this connection should be made
directly to the positive (+) tenninal
of
battery, For safety measures, install an in-line
Fuse Holder (not included) as close to the battery positive (+) tenninal as
possible with an ampere rating; not to exceed total value
of
fuses in Amp.
(3) Remote Turn-On Input:
To
remote turn-on output
of
Car
Stereo
This Amplifier is turned "ON" remotely when the vehicle's stereo is turned "ON".
NOTE:
IF
YOUR RADIO DOES
NOT
HAVE A

WHEN THE
RADIO
IS
TURNED ON, THE

CONTROL FUNCTIONS
I. RCA input jacks
These RCA input jacks are for use with source units that have RCA or Line level
outputs. A source unit with a minimum level
of
180m V is required for proper operation.
The use
of
high quality twisted pair cables
is
recommended
to
decrease the possibility
of
radiated noise entering the system.
2. GAIN Control
The level contro l wi
ll
match the amplifiers sensitivity to the source units signal voltage.
The Operating range
is
180mV minimum to 6V maximum.
CAUT
ION: Do n
ot
run the amplifier in higb volume for long time, otherwise the loudspeakers will be damaged.
3. Full pass x-over switch
When the switch
is
in
the "Full" position , the full range is bypasse
d.
4.
Low pass x-over switch
When the switch
is in the "LPF" position, frequencies lower than the low pass frequency
setting are passed.
4
.1
Low pass x-over frequency control
This control is used to se lect the desired low pass x-over frequency.
The frequency can be adjusted between 50Hz and 500H
z.
5.
High pass x-over switch
When the switch is in the "HPF" position,
frequencies higher than the high pass
frequency setting are passed.
5.
1 High pass x-over frequency control
This control is used to select the desired high pass x-over frequency.
The frequency can be adjusted between 50Hz and 500Hz.

Connect this tenninal directly to the sheet metal chassis
of
the vehicle , using the
shortest wire necessary to make this connection. Always use wire
of
the same gauge
or larger than the (+)
12
volt power wire. The chassis connection point should be
scraped free
of
paint and dirt. Use only quality crimped and/or soldered connectors
at both ends
of
this wire.
Warning: Do not connect this terminal directly to the vehicle battery ground terminal or any otber factory ground
points.
9. Remote Turn On
This tenninal turns on the amplifier when (+)
12
volt
is
applied to
it.
Connect it to the
remote turn on lead
of
the head unit
or
signal source.
10. (+)12 Volt Power
Connect this tenninal through a FUSE
or
CIRCUIT BREAKER to the positive tenninal
of
the vehicle battery or the positive tenninal
of
an isolated audio system battery.
Warning: Always protect this power wire
by
installing a fuse or circuit breaker
of
the appropriate
size within
12
inches
of
the battery terminal connection.
II.
FUSE
These fuses protect the amplifier against internal electrical damage and are meant to
protect the amplifier only. All other power connections should be fused at the source.

1.
Lowest recommended impedance is 20hm stereo and 40hrn bridged mono.
2.
Front and rear outputs must be set for full range operation.
3.
Passive crossovers must be used on all components and frequencies must not overlap.
TROUBLE SHOOTING GUIDE
No power to power wire
Check fuses in amplifier.
Be sure Turn-on lead is connected
Repair power wire or connections
Check connections to radio
Inspect for short circuit
or
an
open connect
ion.
Reverse Left and Right
RCA inputs to determine
if
it
is
occurring before the amp.
Check TunerfDeck volume level.
Clean contacts on fuse holders.
Be sure proper speakers are used
to ensure impedance
recommendations are observed.
(If
you use an Ohmmeter to
check speaker resistance,
please remember that DC
resistance and AC impedance
may not be the same.)

WARNINGS
Investigate the layout
of
your automobile thoroughly before drilling
or
cutting
any holes. Take care when to work near the gas tanks, lines, or hydraulic
lines,
and
electrical wiring. Don't use
power
amplifier unmounted. Attach
this system securely to the automobile
to
prevent damage, particularly
in
the event
of
an accident. Don't mount this system so that the wire
connections are unprotected
or
are subject to pinching or damage from
nearby objects. The
+12
V
DC
power wire must be
fused
at
the battery
positive terminal connection. Before making
or
breaking
power
connections
at this system power terminals, disconnect the
+ 12
V wire
at
the battery end.
Confirm your radiolcassette player and/or other equip
is
turned
off
while
connecting the input
jacks
and
speaker terminals.
If
you need to replace
the
power
fuse, replace it only with a fuse identical to that supplied with the
system. Using a fuse
of
different type or rating may result in damage to this
system which isn't covered by the warranty.
