Staggered Power (Model EC 500.4S):
Two separate power supplies with two separate output sections for the front and rear channels.
In essence, it is 2 completely separate amplifiers sharing the same chassis. More power is created on the rear channels to allow the
performance to be delivered where it is needed most.
Strapped Power (Model EC 1200.1D):
The Mono Block handling subwoofer speakers sometimes need more power. The following RMS
power can be achieved by strapped 2 amplifiers @14.4V:

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