    2. You must use both coils of a dual voice-coil woofer connected 
        either in series or in parallel.
    3. Most amplifiers deliver exactly the same amount of power bridged
        into a 4-ohm load as they do running a 2-ohm stereo load.
To design a subwoofer system that maximizes available amplifier power,
keep the following rules in mind:
    1. The total system impedance of woofers in parallel can be calculated
        using this formula:

– The suggested enclosure volumes are related to only one speaker, including woofer and duct(s)
displaced volume.
– For enclosures with more than one speaker, it is necessary to multiply the suggested volume and
duct(s) by the quantity of speakers.
