Subwoofer help

I used to have an old Fi Btl on 18800 watts rms and handled it fine could have taken way more. Recently sold it and am looking to get either the new 2010 Btl N2 version or the PSI custom subwoofers. I want a 3000 watt rms amp mabe a sundown saz 3000 but am not sure if a fully loaded Btl will handle 3000 watts. My question is can it handle all that power being its rated for 2000 watts or should i get a custom PSI sub that will wasily handle it? also comparisons on the BTL vs. PSI thanks...
