CONNECTIONS

CONNECTIONS ( Fig. 3 Pag. 4 )

1Positive output terminal for left speaker or positive output terminal if used in MONO

2Negative output terminal for left speaker

3Positive output terminal for right speaker

4Negative output terminal for right speaker or negitive output terminal if used in MONO

5RCA-type input connector, left channel or mono

6RCA-type input connector, right channel

720/25 Ampere fuse

8Feed terminal + 12 V to the battery

Connect this terminal directly to a positive (+) terminal of the battery by means of a lead responding to the amplifiers power requirements.

9Terminal for the connection of the negative ground lead

10Terminal for REMOTE switch-on

1.Battery lead . Connect this terminal (+BAT)➇ directly to the battery cable of the car, by using an adequately sectioned cable (yelow).

Do not connect this lead to circuits existing within the electric system of the car. In order to avoid damage to the car it is imperative that this lead be fitted with a fuse (not supplied) as near as possible to the car‘s battery. This connection is to be carried out last.

2.REMOTE switch-on lead (blue). Connect this lead to the remote switch-on lead or connect the control lead of the power antenna coming from the head unit to the REMOTE terminal ➉. NOTE: If this lead is not connected, the amplifier will not be switched on when the head unit is switched on. If your head unit is not fitted with an outlet for a power antenna, a quick-break lever

switch (SPST) should be installed between the power source (+12 V) and the remote switch- on lead and connected to the REMOTE ➉ terminal so as to allow the manual activation of the amplifier.

3.Ground lead . Secure the ground lead to a clean spot on the car chassis and to the GND terminal ➈. Make sure that there is electric continuity between this spot and the negative terminal of the battery. Use the shortest possible ground cable and if more than one amp should be used, connect the relative ground to one sole point.

4.FUSE. In case of fuse replacement be sure to use fuses of the same amperage.

The use of fuses with the wrong amperage may seriously damage the components of the unit.

5.SPEAKER OUTLET TERMINALS. Be sure to keep the right polarity and phase in connecting the speakers. This includes the control of the right polarity, positive (+) and negative (-). NOTE: Avoid any contact between stripped wires and the ground lead.

6.RCA INPUT CONNECTORS. The line output leads of your head unit should be connected to the RCA input connectors, respectively RCA right ≈ and RCA left ➄ , by means of a RCA extension cable ( e.g. 90.05-90.10-90.25-90.50 by MACROM). Be sure to respect the right channel designation: left (white) and right (red).
