[QUOTE="Prowler573, post: 3036239, member: 561023"] When discussing a single voice coil sub Vs. a dual voice coil sub one isn't any inherently better than the other. They will simply require different wiring methods when looking to find appropriate amplification for the sub(s) in question. Ergo ~ If you have a single voice coil 4 Ohm subwoofer and are running only one of them - you know that your amplifier needs to output X amount of power at 4 Ohms to power it. If you have a Dual Voice Coil sub and each coil is rated for 4 Ohms then it gets a bit more complicated. That particular type of sub by itself can be wired to either a final load of 2 Ohms with the coils wired in parallel or a final load of 8 Ohms with the coils wired in series. When you add two dual voice coil subs together it becomes even more complicated for the average novice just getting started in the hobby.
