Message: <blockquote data-quote="oldskolboyz" data-source="post: 2273737" data-attributes="member: 17337">Just learning process, let say:-2-Ohm DVC Sub 400wrms. Mean each voice coil required 200wrms (V1 200w + V2 200w = 400w) either U drive it at 1-Ohm or 4-Ohm, power required wont change (>400wrms).4-Ohm DVC Sub 300wrmsMean each voice coil required 150wrms (V1 150w + V2 150w = 300w) either U drive it at 2-Ohm or 8-Ohm, power required wont change (>300wrms).A DVC sub offers the same performance whether it's wired in series or parallel. Its power handling levels, frequency response, and other specifications do not change, the only difference is the impedance presented to the amplifier. As a result, you'll use the enclosure that's recommended for your sub, no matter how it's wired. Also, keep in mind that most amplifiers need to see a 4-ohm load when bridged to mono operation. If you want to bridge your amp, you should use one 4-ohm speaker or, if you prefer multiple woofers, wire two 8-ohm speakers in parallel. Ohm is unit of measurement for impedance or resistance. It tells you how much a device will resist the flow of current. If you take two signals of exactly the same strength and send one to a 4-ohm speaker and the other to an 8-ohm speaker, twice as much current will flow through the 4-ohm speaker. In other words, the 8-ohm speaker will require twice as much power (wattage) to play at the same volume.</blockquote>
