1. Power Connector: This connector has inputs for Ground,
Remote and Power.
a. Ground: Use the same gauge wire that is being used for the
Power connection and run your ground wire to this negative
terminal. Good ground points are from your battery, a ground
buss or a verified ground location that is clean. This will
minimize the possibility of noise induced into the system.
(Factory head unit ground is not recommended as it can induce
unwanted noise.)
b. Remote: Use a 22 to 18 Gauge wire from your head unit’s
remote turn-on (+12VDC Switched) and run it to remote terminal.
c. Power: Use the supplied in-line fuse and connect it to a
constant positive +12 volt source. Use the same gauge wire
that is used for the ground; preferably 18 Gauge or larger and run
it to the +12 Volt terminal.
2. High Level Input: If you are going to use High Level Input
instead of the Low Level RCA’s inputs, you will need to be set
the gains on your amplifiers lower as the output voltage of the
AP-4EQ is stronger with High Level Input than Low Level RCA
Inputs.
Low Level RCA Connections: Aunex recommends using high
quality RCA Interconnects such as the Aunex AP RCA and AE
RCA series. Consult with your Authorized Aunex Dealer to see
what cable and length works best for your installation. (Note:
Avoid crossing your power and wire ground with your RCA
cables. This will help prevent noise interference.)
3. Main: Use this pair of inputs to connect your main source /
headunit.
