ZR6004 / ZR10001 / ZR20001
- ZR-Series Amplifiers
2. Remote Turn-On
This connection turns the amplifier on and should be connected to the ‘Remote Turn on’
wire from the Head Unit. If one is not available a sw12V 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 amplifier first. Ensure that the location is a good
source of ground (preferably the chassis/floor 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 amplifier.
4A. Speaker Output Connection
(ZR6004 ONLY)
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 amplifier 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.
