WIRING & CONNECTIONS
IMPORTANT:
Before any wiring, always remove the negative terminal of the battery to
prevent short-circuiting. This is also the last lead to be (re-)connected.
Connect this lead only after having completed and checked all other connections. The battery
terminal (+12V) must be connected directly to the positive terminal of the vehicle battery to
provide an adequate voltage source and minimize noise. Connect it to the terminal of the bat-
tery after all other wiring is completed.
GROUND CONNECTION
The ground terminal (GND) connection is also critical to the correct operation of the ampli-
er.Use a wire of the same gauge as the +12V cable and connect it between the ground
terminal(GND)oftheamplierandametalpartofthevehicleclosetothemountinglocation.
This wire should be as short as possible and any paint or rust at the grounding point should
be scraped away to provide a clean metal surface to which the end of the ground wire can
be screwed or bolted.
REMOTE TURN-ON CONNECTION
Theamplieristurnedonbyapplying+12Vtotheremoteturn-onterminal(REM).Thewire
lead to this terminal should be connected to the „Amp remote“ lead from the car stereo which
will provide the +12V only when the car stereo is turned on.
INPUT CONNECTIONS
Thisamplierfeaturesbothhighlevelandlow-level(RCA)inputcapability.Useeitherthe
low-level or high-level inputs, not both. If the car stereo does not provide low-level outputs,
theampliermaybeconnectedviathespeaker(high-level)outputsfromthecarstereo.Wire
the speaker leads from the car stereo to the 4-pin adaptor harness as shown in the diagram
(shielded cables are not required for this application) and plug the connector into the high
inputconnectorontheamplier.
Note:
When using the high-level input of your OE factory radiothat features no
dedicated REM signal, select ”Auto turn-on” ON.
