If aluminium wire is used, it is recommended to increase the size of the gauges to compensate.
The calculation of cable gauge size considers the resistance of terminal connections.
Ensure ALL other cable connections are completed before
connecting this cable to the battery. PHOENIX GOLD ampliers should be connected directly to the 12V battery terminal
using the appropriate gauge cable. Start at the vehicles
battery and run the cable through to the amplier. PHOENIX
GOLD recommends the use of rubber grommets when passing any cable through metal panels to avoid sharp corners or
panels that could cut through the insulation of the cable. An
inline fuse or circuit breaker MUST be used within 30cm (12”) of
your battery; this will prevent the potential risk of a re caused
by a short in your power cable (see spec table for
recommended inline fuse/circuit breaker ratings).
Connect the other end of your power cable to the battery,
but remember to leave the fuse out or circuit breaker off until
all other cable connections are made.
This connection turns the amplier on and should be connected to the ‘Remote Turn on’
wire from the Head Unit. If one is not available a switched +12V source must be used,
such as a power antenna wire or ACC +12V.
If you are using high level (speaker) inputs and a remote turn on wire is not available, then
instead the ‘Auto Turn-On’ switch must be set to ON.
3. Ground
Connect the Ground/Earth cable for your amplier rst. Ensure that the location is a good
source of ground (preferably the chassis/oor pan). Investigate the area you wish to use
to ensure it is free of wiring, vacuum lines, brake and fuel lines. Use either a wire brush or
sandpaper to expose bare metal, this will provide a high current contact for your ground
connection. Use the same gauge cable for the ground cable as you did for the power
cable. Secure the ground cable to the ground point with a bolt, star washer and nut.
Apply some neutral cure silicon to the bolt and bare metal to prevent possible water
leaks and rust. Connect the other end of your ground cable to the amplier.
4A. Speaker Output Connection
(ZR6004R - ZR12005)
Ensure the correct polarity is observed when connecting
speakers/subwoofers.
2ohm minimum speaker impedance for stereo
operation (per channel).
4ohm minimum speaker impedance for bridged
operation.
4B. Internally Linked Output
(ZR10001 - ZR20001)
The ZR20001 Monoblock amplier provides dual output
connections to simplify wiring when using 2 subwoofers
or a dual voice coil subwoofer. Both positive and
negative terminals and internally connected or linked
in parallel. For dual coil (2 x 4ohm) or two single coil
(4 ohm) subwoofers connect each coil to positive or
negative terminal. For a standard single coil subwoofer
connect to either positive and either negative terminal.
Choose the correct length RCA cables to connect the RCA outputs of the source/head
unit, to the input connectors of the amplier. The RCA inputs also accept ‘high level
input’, when using a high level signal, the amplier will autostart without the need of a
remote signal.
Run the RCA cables on the opposite side of the vehicle. to the power cable and vehicle
wiring loom. Avoid the electric fan motor and wiring. Ensure you follow the correct
balance. (L LEFT = White or Black. R Right = Red)
6. Gain/Level Control (Sub/Front/Rear)
This control is used to match the input level of the amplier to the output level of your
head unit. We recommend the method below, as failure to follow these steps may
damage the audio system.
1. Turn the amplier Gain to zero
2. Turn the volume of the head unit to ¾ and the bass and treble to zero
3. Adjust the amplier Gain/Level control until the desired maximum volume is
achieved without distortion.
4. Make ne adjustments to tune your install.
7. High Pass Crossover Filter
Set the crossover switch to HP and turn this control to 65Hz or above when using speaker’s
smaller than 6 x 9”. When a subwoofer is used in the system, this feature is designed to
lter out all low bass frequencies that only subwoofers should produce.
See specication table for adjustable frequency range.
8. Low Pass Crossover Filter
Ensure the crossover frequency is set at 100Hz or below. This feature must be used with
a subwoofer to lter out all mid to high frequencies that only full range speakers should
produce. See specication table for adjustable frequency range
9. Crossover Switch (ZR6004R & ZR12005)
Full - This setting is for large speakers (e.g. 6 X 9”) or speakers when a sub
woofer is not included in the system. The amplied audio signal is not ltered
so the full range audio signal is sent to the speakers.
Low - This setting is used when using a subwoofer and will only allow
frequencies below the low pass lter setting to pass through.
High - Used to run mid-range speakers when a separate subwoofer is connected. This setting will only allow frequencies above the set high pass lter
setting to pass through.
10. Subsonic Filter
This is a variable control that lters out all subsonic bass frequencies below the set point.
These are frequencies that are not audible. These frequencies can damage
subwoofers. See specication table for adjustable frequency range.
This control adjusts the bass boost at 45Hz, from 0 to +18dB. Start from 0 and slowly
increase to the desired level. Use this control with extreme care as failure to do so may
result in damage to the subwoofers.
12. Remote Control Port
This connection should be used with the included remote control (ZRBC) to adjust the
bass level from any location within the vehicle.
ZR6004R remote to control the Gain level in the rear channels.
13. Phase Switch
This control adjusts the phase shift 180 degrees for the subwoofer. This means that the
subwoofer will move inwards instead of outwards on a sinus wave.
14. Power / Protect LED
1. When illuminated Blue, indicates normal operation. Amplier is powered on with no
faults detected.
2. When illuminated Red, indicates the amplier is in protection mode / fault state. See
