INSTALLATION
DAISY CHAIN
Daisy chain connection allows linking of 2 same amplifiers to work as 1 single amplifier.
Please read the following connection diagram cautiosly to ensure the correct connection.
Step 1. Connec the master amplifier to the head unit
Step 2. Connect the master slave amplifier in daisy chain RCA jack as shown in the
diagram.
Step 3. Connect speaker cable (+) on master amplifier to subwoofer (+)
Step 4. Connect speaker cable (+) on slave amplifier to subwoofer (-)
Step 5. Connect speaker cable (-) on master amplifier to speaker cable (-) on slave
amplifier using 8 AWG wire cable.
The minimum impedance as 1 unit is 1 Ohm.
In a daisy chain configuration the minimum impedance is 2 Ohm.
CAUTION
Before attempting to make any connections to power supply, input and output
connectors, make sure the amplifier is in OFF state. Check polarity of cables carefully
as using reversed polarity will cause damage to the amplifier. And to prevent power
loss and overheating of wiring, always use the recommended wire gauges.
CAUTION
Installation of the amplifier should be done in the following steps:
1. Ensure that the ground is appropiate, then connect i to the amplifier.
2. Next step is to connect the +12V wire. Ensure all power terminals are used. This
cable has to be fused at the battery for safety precautions.
3. The final step is connecting the switched remote.
Keep GROUND of equal lenght. This drawing is for illustration purpose only
We recommend using 12 AWG speaker cables to obtain intended performance. Run
12 AWG speaker cables from your speakers to the amplifier's mounting location.
Keep the speaker cables separate from the power cables and the amplifier's input
cables. Use grommets where the cables have to penetrate the vehicle chassis.
Connect the speaker wires according to the terminals on each speaker.
Strip 1cm, 3/8" of insulation of the end of each cable and twist the cables strands
together tightly. Make sure there are no strays strands that might touch other cables
or terminals and cause short circuit. Connect the cable ends to the amplifier as
shown in the speaker wiring diagram.
