Adjusting Crossover Frequency
Do the following individually for each channel.
Placing the crossover switch in one of the HP
positions sets the amplifier to the High Pass
mode, enabling frequencies above the 60Hz
or 80Hz cut-off point to pass.
Placing the crossover switch in the AP position sets the amplifier
to the All Pass mode, preventing any crossover adjustment,
allowing all frequencies to pass.
Placing the crossover switch in the LP position sets the amplifier
to the Low Pass mode, enabling frequencies below the 80HZ
cut-off point to pass.
2/4 Channel Switch
Setting this switch to the 2CH. position, switches the
inputs to a 2-channel mode, allowing connection to only
the front inputs with a 4-channel output.
Output controls function the same as if the amplifier
was in 4-channel mode.
All "ACTIVE" inputs must have RCA jacks connected.
Switch in 2CH. position,"ACTIVE" - Front channel inputs only.
Switch in 4CH. position,"ACTIVE" - All Front and Rear channel
inputs.
NOTE: When connecting to the 4-Channel inputs, be sure to
route both front and rear RCA cables tightly together.
High Level Input
Connect from source signal by plugging into the RCA input jacks
at the amplifier. The input sensitivity ranges from 150mV-12V
to accommodate signal from high-level (speaker) input.
utilizing high-level for input signal the auto turn-on feature is
active. With the auto turn-on active,
to turn on/off up to two additional amplifiers or other accessories.

Troubleshooting
NOTE: If you are having problems after installation follow the
Troubleshooting procedures below.
Check Amplifier for proper connections. Verify that POWER light is on. If
POWER light is on skip to Step 3, if not continue.
1. Check in-line fuse on battery positive cable. Replace if
necessary.
2. Check fuse(s) on amplifier. Replace if necessary.
3. Verify that Ground connection is connected to clean metal
on the vehicle's chassis. Repair/replace if necessary.
4. Verify there is 9 to 14.4 Volts present at the positive battery
and remote turn-on cable. Verify quality connections for
both cables at amplifier, stereo, and battery/fuse holder.
Repair/replace if necessary.
Protect light is on.
1. If the Protect light is on, this is a sign of a possible short
in the speaker connections. Check for proper speaker
connections and use a volt/ohm meter to check for
possible shorts in the speaker wiring. Too low of a speaker
impedance may also cause Protect to light.
Check Amplifier for audio output.
1. Verify good RCA input connections at stereo and amplifier.
Check entire length of cables for kinks, splices, etc. Test
RCA inputs for AC volts with stereo on. Repair/replace if
necessary.
2. Disconnect RCA input from amplifier. Connect RCA input
from test stereo directly to amplifier input.
Check Amplifier if you experience Turn-on Pop.
1. Disconnect input signal to amplifier and turn amplifier on
and off.
2. If the noise is eliminated, connect the REMOTE lead of
amplifier to source unit with a delay turn-on module.
OR
1. Use a different 12 Volt source for REMOTE lead of amplifier.
Check Amplifier if you experience excess Engine Noise.
1. Route all signal carrying wires (RCA, Speaker cables) away
from power and ground wires.
OR
1. Bypass any and all electrical components between the
stereo and the amplifier(s). Connect stereo directly to input
of amplifier. If noise goes away the unit being bypassed is
the cause of the noise.
OR
1. Remove existing ground wires for all electrical components.
Reground wires to different locations. Verify that grounding
location is clean, shiny metal free of paint, rust etc.
OR
1. Add secondary ground cable from negative battery terminal
to the chassis metal or engine block of vehicle.
OR
1. Have alternator and battery load tested by your mechanic.
Verify good working order of vehicle electrical system
including distributor, spark plugs, spark plug wires, voltage
regulator etc.
