Power Supply & Output Panel Connections
Power Supply Terminal:
Œ
Ground (GND):
The ground
Ÿ
terminal must be connected to a
metal part of the vehicle with
ground plane back to the main
battery ground attachment point
(a.k.a. chassis ground). This wire
should be as short as possible,
but no longer than 2ft (60cm),
with minimum gauge of 8AWG.
The ground wire should be terminated with a ground specific or ring terminal and securely
bolted to the vehicle with star or lock washer and nut to prevent from coming loose. The
chassis ground connection point should be scuffed to the bare metal.
Remote Turn-on (REM):
If the source unit has a remote output wire (+12V switched output),
Ÿ
connect it to the REM terminal. If a remote lead is unavailable, the amplifier will automatically
turn-on by detecting DC-offset or audio signal from the source. While auto turn-on works well
in most applications, there may be some cases were a +12V trigger is preferable or necessary.
Both detect functions are enabled by default, but can be individually defeated via the two
jumpers located on the input panel.
Ÿ
Power (+12V):
The co12V power connection must be made at the vehicle's main
battery, securely connected with a ring terminal and protected with an in-line fuse within 18in
(45cm) from the positive battery terminal. The link300.4mini requires a 40A external in-line
fuse (not included) and a minimum power wire gauge of 8AWG. Do not install the fuse until all
other system connections have been made.
Speaker Output Terminal:
Each (+) and (-) terminal pair per channel is for connecting the
amplifier's output to speaker(s) or subwoofer(s). Make sure to observe correct polarity and
total impedance per channel. The minimum nominal impedance is 2
Ω
per channel, or 4
Ω
for
bridged connections.
Mounting Tabs:
These mounting tabs are pre-attached and should be used to properly secure
Ž
the amplifier with appropriate screws (not included) during installation to a solid mounting
surface that is directly attached to the metal structure of the vehicle cabin. These tabs are
removable if the unit can be safely secured by another method.
System Wiring
It is important to read this manual thoroughly before starting your installation and always plan
accordingly. Before installing any Wāvtech product, disconnect the negative (ground) wire from
the vehicle’s battery to avoid damage to the vehicle or yourself. Following all guidelines will ensure
years of enjoyment with your Wāvtech amplifier.
