JENSEN
JA SERIES
Connection Descriptions
NOTE:
Be sure to follow specific instructions included with your amplifier installation kit
(not included with this amplifier). The information below should be used as a general
guideline only.
Power Wire (+ 12V)
• Disconnect negative battery terminal before proceeding. Consult a qualified
technician
for instructions if you are unsure.
• Plan wire routing before cutting any wires to length. Begin by routing the power
+ 12V wire from the battery to the amplifier location. Use a grommet when running
wires through the firewall
or metal openings. Avoid running the power wire near
existing vehicle wiring to prevent induced noise from entering the audio system.
• Use extreme caution when drilling holes to avoid damaging fuel lines
or existing
vehicle wiring.
•
The + 12V wire MUST be fused within 18" of the battery for protection of the vehicle's
electrical system.
Ground Wire (GND)
• The amplifier ground wire should be as short as possible (no more than 36" or
1 meter). Choose a clean unpainted section of metal or the vehicle chassis when
attaching the ground connection.
Be sure to clean the area of any dirt or grease.
Remote Tum-on Wire (REM)
• The remote turn-on wire connects to the head unit's amplifier turn-on lead or
power antenna output.
Speaker Wires
• Choose adequate gauge speaker wire depending on your exact amplifier/speaker
combination.
Be sure to observe polarity when connecting.
•
Do not ground any speaker wires or connect any speaker wires together.
Input Signal
• The amplifier's input signal connects to the head unit's low level (RCA) or high level
(speaker wire) outputs.
• Low level input signals deliver the best performance. If unavailable. use the high
level inputs - when interfacing with factory head unit
for instance.
Power/ Protect Indicators
• Colored LED indicators illuminate from the plastic power terminal.
• The blue LED illuminates during normal operation (POWER) and the red
LED indicator is visible when the amplifier detects a fault (PROTECT).
CAUTION
• Do not use both low and high level inputs at the same time. Connect only one or the
other.
• Keep low level inputs away from any power wires to avoid engine noise.
• Never run any wires underneath
or outside the vehicle.
