What does ohm load mean? What is the difference between dual voice coil and single voice coil subs?
the ohm load is the total resistance that your amp is seeing when wired up to the subs/speakers. In general, lower ohm loads will mean that your amp will be putting out more power. However, you need to make sure that your amp is stable at that ohm load or you will cause significant damage. The ohm load can be changed by wiring the subs differently, ie. Parallel vs. series. To determine ohm load when wired in series, the ohm load = Resistance1 +Resistance2+Resistance3+….. to determine ohm load when wired in parallel, the ohm load = 1/(1/R1+1/R2+1/R3+….). Dual voice coil subs have the advantage of adjustability. A single voice coil sub can only be wired at the resistance of that one voice coil, unless of course you have a multiple woofer setup. However, a dual voice coil sub can have the voice coils wired in series or parallel, allowing for two possible ohm loads from one woofer. As an example, a dual voice coil woofer with a resistance of 2ohms per vc (voice coil) can be wired in pa
