Fig.12  Two Single Voice Coil Subwoofers (2-4 Ohm)

2. TWO SINGLE VOICE COIL SUBWOOFER SPEAKER

 

    (Note: Don’t connect speaker impedance under 2 ohms)

Fig.11   A Single Voice Coil Subwoofer (1~4 ohm) 

Too low of an impedance could send your amplifier into protection mode and/or permanently damage the 
amplifier.
At the amplifier end, insert the stripped (bare) speaker wires into the properly marked terminals. Use a 
Philips (cross) screwdriver to loosen the speaker terminals on the amplifier. Make certain that no bare wire 
ends touch each other.  Such contact could result in an electrical short and cause the amplifier to turn off 
(short circuit protection) or malfunction.
