Do you actually have the amp yet, or are you just intending to purchase it? If you haven't bought it yet, I'd recommend going with something a little more electrical-friendly unless you're looking for balls to the wall SPL... 3,000 watts would do just fine for either of those subs you mentioned - even 3kw might be a little excessive for daily on one sub though.

If you're dead set on a maxximus, you should probably get a sub that's a little more geared towards SPL to handle the abuse.
