Operation

STRAPPING AMPLIFIERS (S4.1000.1D Only)

The S4.1000.1D amplifiers have the ability to connect two together and have their outputs
combined, or strapped, to power a single speaker load.
CAUTION: Two S4.1000.1D amplifiers that are strapped together are not
recommended for impedance loads below 2
1. Select which amplifier of the two will be the master. and set the Master/Slave switch in the
"out" position.
NOTE: Only adjustments made to the master amplifier will effect the output to the connected
speaker.
2. Connect RCA cables from the source signal to the input connection on the master amplifier.
3. Set the Master / Slave switch on the slave amplifier to the "in" position.
4. Connect a RCA cable from the MAS OUT connector on the master amplifier to the SLV IN
connector on the slave amplifier.
5. Connect one of the negative (-) speaker outputs from the master amplifier to one of the
negative (-) speaker outputs on the slave amplifier using a 10 gauge wire (minimum).
6. Connect one of the positive (+) speaker outputs from the master amplifier to the positive (+)
terminal of the speaker being use.
7. Connect one of the positive (+) speaker outputs from the slave amplifier to the negative (-)
terminal of the speaker being use.

Troubleshooting

Symptom
Amplifier does not
turn on.
Amplifier Noise
(Turn-On Pop)
Engine Noise
Diagnosis
B+ or REM not between 10.5 and
15.5 volts or no voltage present
Amplifier is not properly grounded.
Voltage spike from source unit is
entering amplifier's input
Noise is radiating into signal cables
.
Remedy
Check the alternator, battery, fuse,
and wiring and repair as necessary
Check wiring and repair as necessary
Connect a relay turn-on module to
REM terminal if pops are eliminated
with no input signal to amplifier
Re-route signal cables away from
sources of high current
