2 subs @ 4 Ohm each, wired in parallel, how does this create a 2 Ohm resistance for the 2 subs altogether?

Question

I have wired my subs in parallel with each other. + from amp to + sub 1 to + sub 2 to create a 2 Ohm resistance (as with the negative). Why dont you still get a 4 Ohm resistance, with 2 subs @ 4 Ohm each=8 Ohms?? how does this work. Also have tested with my meter on DC Ohms and reads to about 1 Ohm? cheers

Answer 1

To get 8 ohms, connect in series... +amp to +sub1 from -sub1 to +sub2 from -sub2 to -amp.  Here you add IMPEDANCE.  Impedance varies (inductors increase impedance with frequency, capacitors drop impedance with frequency) an ohmeter measures at DC (no frequency change or freq=0).  Parallel formula is (sub1*sub2)/(sub1+sub2)

So: (4*4)/(4+4) = 16/8 = 2 ohms

Answer 2

2 4 ohms dvc subs wired in parrallel will create a 1 ohm load

Answer 3

The effective resistance of two resistors wired in parallel is given by 1/R = 1/R1 + 1/R2.  Applying this to two 4-ohm ones, you get two ohms.  Note that the DC resistance does not equal the AC impedance: the speakers are converting electric energy into sound energy, which raises the impedance.
