[QUOTE="helotaxi, post: 4771763, member: 550915"] True. In a series circuit the voltage is divided between the loads in inverse proportion to the resistance/impedance of in the individual loads. In a parallel circuit the voltage is the same on every load in the circuit and the current is divided in inverse proportion to the impedance/resistance.You are mistaken here. Say that you have 2 DVC 2 ohm drivers and you want a 2 ohm final load. There are two ways to wire this. First is to series wire the coils of each driver to create 2x 4 ohm loads and then parallel those for a 2 ohm final load (this is the better method but not for reasons of heat into the coils as I'll demonstrate in a seoncd). The second is to parallel the coils on each driver for 2x 1 ohm loads and then series the drivers for a final load of 2 ohms. Now let's look at the voltage and current (power) into each coil in the system. We'll assume that we have 800w @ 2 ohms (cause it makes the math easy). For wiring method #1, voltage at the amp terminals would be 40V and total current would be 20A. Voltage to each driver would be 40v (voltage is constant in a parallel circuit) and the current through each driver would be 10A. Now that gives us 400w to each driver. Each driver has 2 coils that we wired in series. Current is constant in a series circuit so each coil is seeing 10A of current and voltage in proportional per Ohm's law so we have 20V dropped across each coil. The result is that there is 10A @ 20V for 200w on each coil. Now let's look at situation #2. We have the same final load on the same amp so we have the same basic voltage and current. The drivers are in series this time so current is constant on each driver @ 20A. The voltage is divided evenly, so 20V each for a total of 400w per driver. On each driver the coils are in parallel so the voltage is constant and the current is split and once again we find that each coil is seeing 10A @ 20V for a total of 200W. If you can explain how the same voltage and current heats the coil differently simply because of how it's wired in a circuit, the Nobel foundation has a million dollars for you. Now parallel wiring between drivers has an advantage in that the amp acts as a shunt for back EMF and reduces intermodulation between drivers, but that does not reduce the heating of the coils in the system.
