S YSTEM C ONFIGURATION #3
1 Channel, Dual, Single Voice Coil Subwoofer Mode
Possibly as popular as the single woofer is a pair of
single voice coil subs in a standard "wedge" box for a
vehicle trunk. Assuming each coil is 8 ohms, this places
a load of 4 ohms on the amp which is fine. If each woofer is 4 ohms, this places a load of 2 ohms total which
is possible for short periods but not recommended due to overheating of the amp and possible damage if used
long term like this.

S YSTEM C ONFIGURATION #4
1 channel, Dual, Dual Voice Coil Subwoofer Mode
Dual, DVC subwoofers in a common wedge box in a car
works great but is often forgotten. For a pair of DVC
subwoofers with dual 4 ohm coils, this produces a 2 ohm
load. Now, by placing these 2 speakers in series, we
achieve a 4 ohm load to the amp which just works great! This can be a real pounder system if wired up right
and places only moderate loads on the amp. Highly recommended!
