4 HIGH PASS:
Set the crossover switch 2 to HP and turn this control to 65Hz or above when using speakers smaller than
6 x 9”. This feature is designed to filter out all low bass frequencies that only subwoofers should produce.
Note: Failure to do so could result in speaker damage.
5 LEVEL:
This allows level adjustment of the input signal. Use this control to correctly match the head unit to the
amplifier. To set this control correctly, turn the amplifier level to MIN and the head unit to 3/4 volume, with
the bass and treble on zero, then slowly turn up this amplifier level control towards the MAX end of the
control. Note: If the sound becomes distorted, turn this control down.
6 RCA INPUT:
Connect these RCA connectors to a head unit with a low level output connection.
7 RCA OUTPUT:
Use these RCA output connectors to connect to a secondary amplifier. This output is a pass-thru
connection derived from the RCA input connector so the signal level and frequency response is the same as
the original input signal.
8 GROUND INPUT:
Connect directly to the vehicle’s chassis via a 8 gauge power cable.
Note: This is to be the first wire to connect when wiring up an amplifier ,damage could result if this is
not done.
9 REMOTE INPUT:
This terminal is for turning the amplifier on and off. This requires a switched positive (+12V) to power ‘ON’
the amplifier, this can be found on the rear of the head unit in the form of a electric antenna output, or a
remote on output. If not available you can wire to the ACC position on the key.
10 +12V INPUT:
This must be connected to the vehicle battery positive (+) terminal via an 8 gauge power cable and with an
inline fuse or circuit breaker at the battery end.
Note: This is the last wire to connect up during installation as damage could result.
11 FUSES:
Please ensure correct type of fuse is fitted, as specified in this manual.
Note: EN-AM3002 has 1 x 25A fuse, EN-AM4502 has 1 x 35A fuse.
12 SPEAKER OUTPUT:
See 2/1 channel installation diagrams on page 28 for correct speaker connection.
