1. If you are experiencing a “high” noise floor/engine whine;
a) Try the unbalanced/balanced switch in both positions to see which position has the lowest noise floor.
b) For OEM or Aftermarket headunits, using a 4 ohm tweeter with 6” of wire, unplug the input to the 3Sixty.3 (RCA or Speaker wire) and connect it to the
tweeter. Toggle the headunit volume between 0 & 1.
c) If you can hear the high noise floor from the tweeter go to step (d). If you cannot hear the high noise floor from the tweeter go to step (f).
d) To insure the noise is not being induced through the speaker input wire or RCA cable between the source unit and the 3Sixty.3, remove the source
unit and connect the tweeter to the speaker output or RCA output depending on if you are using a high or low level input. If the noise it still audible in the
tweeter proceed to step (e). If it is not audible replace or reroute the input cables to the 3Sixty.3.
e) Reconnect all the inputs to the 3Sixty.3. Connect the USB to the 3Sixty.3. In the SETUP menu select reconfigure inputs. In the “Adjust source level”
window reduce the volume level from the source unit. For example if the volume on the headunit is 0-40 and the first time the system found you could turn
the headunit up to 30 before it started to distort reduce it to 25 then press the “Auto Range”. NOTE Depending on the desired volume level you may have to
increase the amplifier gain.
f) Reconnect all the inputs to the 3Sixty.3, remove the outputs from the 3Sixty.3 and connect the tweeter to the RCA output of the 3Sixty.3. Toggle the
headunit volume between 0 & 1.
g) If you can hear the high noise floor from the tweeter go to step (i). If you cannot hear the high noise floor from the tweeter go to step (j).
i) Make sure the headunit and 3Sixty.3 are grounded at the same point in the vehicle to eliminate a ground loop from forming.
j) With all the inputs removed to the amplifier use Shunt Plugs on each RCA to connect the inside and outside of the RCA connects together. You can cut
and twist the two wires in an old RCA cable to create a Shunt Plug. Remove all the output speaker connections to the amplifier and connect the tweeter we
used in the previous steps. If you can hear the noise floor from the tweeter go to step (k). If you cannot hear the high noise floor from the tweeter go to step
(l).
k) Reduce the amplifier gain until the noise is no longer audible. Reconnect the entire system if the system is not “loud” enough with the gain setting where
it currently is you have two options. First option is to turn up the amplifier gain which will turn up the noise floor (this occurs because the amplifier has a
poor S/N). Second option is to replace the amplifier with a higher power amplifier or one with a higher S/N.
l) The noise is being induced onto the speaker wires between the amplifier and the speakers. You will need to reroute the speaker wires away from any
