This is the wiring diagram for woofers with dual 2 ohm voice coils. This will give you a 2 ohm load. The voice coils of each individual speakers are wired in series. This gives each speaker an 4 ohm impedance. Wiring them in parallel will present the amp with a 2 ohm load. You can...
The load resistanceRloadshould not be too small, because the output is too heavily burdened and should not be too large, as this will change the voltage very little and leads to measurement errors. For output impedance of a normal power amplifier to operate a speaker aRloadresistance of about...
