WIRING EXAMPLES A4

example.
All speakers must be 4 ohm.
If the head unit has only one pre out a
Y-cable must be used.

DLS A4 is 1 ohm stable. This means that you can connect two 4
ohm subwoofers in parallel without damaging the amplifier. Two 4
ohm subwoofers connected in parallel results in a 2 ohm load which
the amplifier sees as a 1 ohm load.
Subwoofer
If you have a 4 ohm sub with dual voice coils you can connect the
4 ohm
coils in parallel.
