[QUOTE="Ed Lester, post: 4383899, member: 587479"] I am an expert. Running one coil on a DVC sub can and will damage it. There can be excess EMF built up in the coil not being powered. this can create excess heat. Remember that a dual coil sub does not have the same coils as a single coil sub times 2. The sub is designed to use both coils and will not move properly without both coils hooked up. Movement can be non-linear and thus be distorted. That amp may not be rated at 2ohms bridged but if you DC voltage in is kept above 12.6 then it will run 2 ohms fine. Wire 2 coils in parallel or even wire each coil to its own channel. Anyway you do it, wire all coils. If you ran 1 coil of a dual coil sub for a few years with no problem, you were lucky. But I bet the sub never played as good as it should have ever again. If those articles say otherwise, they are wrong. I know some of the guys that write them, not all are experts. [/QUOTE]
