Connect the fuse holder as close to the vehicle battery + as possible, using AWG 5 = 16 mm2 or heavier cable (see table on page 2). Use ring crimp terminal cable to connect to battery +. Apply silicon grease to the

Connect the battery cable to the +12 Volt terminal on the amplifier. Model A2, A5 and A7 accepts AWG 4 = 21 mm2 direct into the terminal, A1, and A8 accepts AWG5 = 16 mm2 direct into the terminal. Be sure to use a rubber grommet or a plastic insulating tube where the cable passes the firewall or other places where it can easily be jammed.
Use wire ties to secure to existing cables in the engine compartment.

These models have double DC inputs. The termin- als are internally connected so it´s enough to connect just one of them. If you want to reduce the voltage drop to the amplifier, use both inputs. The extra DC input can also be used for the connection of a Power Capacitor or an extra battery. See the example above. These amplifiers requires a powerful fuse holder like the FH2B with an ANL 150 Amp fuse (when using 2AWG / 33 mm2 power cable).

For RCA cable signal input:

Connect the radio power antenna lead = remote turn on/off from the head unit to the amplifier remote connection. This turns on the amplifier whenever the car stereo is turned on.

You can either use the built in remote cable in the RCA cable itself, or use a separate cable. Sometimes a small disturbance may enter the amplifier coming from the remote voltage, through the built in remote wire and into the RCA cable. Thus we recommend to use a separate remote wire and run the RCA lead separate from remote wire, power cables and speaker cables.

You can insert the cable directly into the amplifier terminal. If there is no remote voltage available from the stereo, you must connect to the ignition key,

through the radio, or any accessories fuse.

Ground Terminal ( GND )

Connect to a good chassis ground. The ground connection should be clean, unpainted metal to prov- ide a good electrical connection. Use a wire brush, a scraper or a piece of an abrasive sheet to clean the metal. Use a lock washer or two to secure contact. Protect with silicon grease or by paint applied

afterwards.

Fuses

Use only ATC blade type fuses. Make sure to replace with the same value. The value is printed above the fuse holders. DLS A4 has no internal fuses, use an external fuse instead.
