"John, on your drawing, it has the positive and negative from the amp coming into opposite drivers, at each end of the circuit, but on the 12 volt calc, it has the positive and negative coming into the same driver, different VC's and series-ing the coils from there to a loop from + to - on the final two VC's of the second driver. Any reason one works better than the other? Like this:"
the car stereo diagram has the 2 VOICE COILS wired in PARALLEL, 2 ohms per coil, gives 1 ohm net per driver.
then it has the 4 DRIVERS, 1 ohm net per driver, wired in SERIES to produce a net of 4 ohms total.
my picture had the 2 VOICE COILS wired in SERIES, 2 ohms per coil, gives 4 ohm net per driver.
the it has 2 DRIVERS wired in SERIES, 4 ohms per driver, to produce 8 ohms per PAIR
then it has the 2 PAIRS, 8 ohm net per PAIR, wired in PARALLEL to produce a net of 4 ohms total to the amp.
there are reasons why my suggested plan will be better, at least in theory. from a practical perspective, the only way to know would be to test.
