EARTHQUAKE SOUND • RECOMMENDED SUBWOOFER ENCLOSURES 3

HOW TO WIRE YOUR EARTHQUAKE SUBWOOFER

WIRING CONFIGURATIONS

According to Ohm laws, when speakers are wired in parallel. The formula is: 1R=1R1+1R2+1R3+·s+1Rn Where R= Total system impedance

Series formula: Rt= R1+R2+R3+.... Where Rt= Resistance seen by amplifier

If using SINGLE 2 OHM coils the total load would be 2.0 ohm
If using SINGLE 4 OHM coils the total load would be 4.0 ohm
If using SINGLE 6 OHM coils the total load would be 6.0 ohm
If using SINGLE 8 OHM coils the total load would be 8.0 ohm

If using SINGLE 2 OHM coils the total load would be 1.0 ohm
If using SINGLE 4 OHM coils the total load would be 2.0 ohm
If using SINGLE 6 OHM coils the total load would be 3.0 ohm
If using SINGLE 8 OHM coils the total load would be 4.0 ohm
