I can't seem to come across a solid answer for this, so here's my question... If a sub's wattage rating is 225W RMS per coil (DVC), and both coils are wired to one channel, should the amp optimally be pushing 450 watts RMS to that channel no matter the impedence (2 ohm or 8 ohm)? Maybe I'm looking to deeply into this, but just wondering if anyone has some thoughts. Thanks.

 

nope. what a sub is rated at is what it can handle, not what the amp puts to it. if you have an amp that puts out 150 watts RMS @ 4 ohms (just an example), and your sub is rated at 225 RMS, the amp is only going to put out 150 watts RMS. the sub does not change that. doesnt matter if its SVC or DVC. the only things that will change the amp's output is the # of ohms. and if that was the wrong answer, then here's another stab at it (was kinda confused by the question). if its dvc, then yes, it can handle 450 rms at any impedence when both coils are hooked up. however (to get more technical), ratings are subjective when you start talking about different size boxes....

 

Ah... ok yes, you answered my question in your second part. Thanks!!

450W at 8 ohm is fine as long as the DVCs are wired in series.
450W at 2 ohm is fine as long as they're wired parallel.

That's all I needed to know.
