The phase control can be set continuously from 0 - 180 degrees. This is very useful when you want to adjust the bass sound for best front stage image. Start on 0 and turn the control slowly clockwise until you experience the bass sound coming from the front.
You may have to change the polarity of the speaker connection to get the best result.

The speaker terminals are
doubled for easier connection of moreof two or m o r e subwoofers. The
+respective - terminasls are i n t e r n a l l y connected to each other. It is not possible to connect CA12 in bridge mode.
When wiring is complete, reconnect the battery negative terminal.
Test power wiring
1.Turn on the head unit but do not turn up the volume. The amplifier power light should come on. If not, check the remote and +12 volt wires. Also check the ground connection.
2.Turn up the head units volume slightly. All speakers should operate. if not, check wiring connections at amplifier and speakers.
NOTE!
Minimum speaker load is one (1) ohm. You can connect up to four 4 ohm subwoofers or two 2 ohm subwoofers to the amplifier. Loads or speaker impedances less than 1 ohm could result in poor sound quality and/or damage to amplifier.
The drawing shows how to connect four 4 ohm subwoofers to the speaker terminal.
