the (-) speaker output and the red (positive) probe to the (+)
speaker output.
9. Start slowly increasing the gain until your target voltage from
step one is achieved. If there are multiple amplifiers (more than
one of the same sub amplifier). Set all amplifiers to the same
output voltage.
10. Now turn source unit down and reconnect speakers.
11. Play music you are familiar with and listen to the system to deter-
mine if it's too loud. If the system is too loud; turn the gain down
until a desired output is achieved. Never turn the gain up because
clipping and distortion may occur.
12. Your system is now properly tuned to its maximum potential.
Enjoy!

Amplifier Visual Troubleshooting

Your new Orion HCCA amplifier has three indicator lights (LED's) on
the top cover of the amplifier as seen in the next figure. These lights
are very useful in troubleshooting possible amplifier problems and
issues.
Power LED: This LED lights up green when the amplifier is turned on.
This represents normal operation if the Protection/ESP Status LED is on
solid, and the Thermal LED is off.
Protection /ESP Status Indicator LED: This LED lights up blue if the
amplifier goes into protection. It also will flash when the amplifier
is powering up, approximately 4-5 flashes until the turn-on delay
has expired (actual number of flashes depends on the length of
time selected via the bitwriter). Below is a description of reasons
the amplifier could engage the protection circuit. The protection
indications will self reset once the condition has been fixed. Advanced
troubleshooting can be performed using the ESP Status LED.
Short: Speaker wires pinched or shorted together or to ground
(frame of vehicle). ESP Status LED will also flash two short flashes,
followed by a long pause( approximately 8-10 seconds).
Overcurrent: Check for possible speaker issue(s) or speaker wiring
pinched in a door or other metal. Make sure speaker(s) load is
not below minimum 1Ω load. The ESP Status LED will also flash 2
short pulses, followed by a long pause.
DC Offset: This can happen if the installation inadvertently
connects the power wire to the speaker input(s). This can also
happen if the amplifier has an internal problem. The amplifier
will flash 4 short pulses, followed by a long pause, then repeat.
Undervoltage: Vehicle charging system is not supplying enough
voltage to the amplifier. This can also occur if you use too small
