WIRING INSTRUCTIONS
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 bat-
tery terminal (+12V) must be connected directly to the positive terminal of the vehicle battery
to provide an adequate voltage source and minimize noise. Connecting the battery terminal
lead to any other point (such as the fuse block ) will reduce the power output and may cause
noise and distortion. Connect it to the terminal of the battery 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 power connection 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. If the car stereo does not
provide an „Amp remote“ lead, the remote turn-on lead may be wired to an „Accessory“ or
„Radio“terminalinthecar‘sfuseblock.Thiswillturntheamplieronandoffwiththeignition
key, regardless of whether the car stereo is on or off. The remote turn-on lead does not carry
large currents. So a thin wire may be used for this application.
INPUT CONNECTIONS
This amplier features both high level and low-level 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 5-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.
