My 12s are in 5.5 cu each after displacement. 1500w each. Thing is nasty. Doesn't meter worth a crap, but don't care. It hurts, it sounds good, it impresses people. I want to do the same thing, just bigger. I got the Warhorse for the same money I could have got a used 3500, so I'm going to hope to get 9,000w out of it at 14.4 with a good electrical. Put some efficient, cheap woofers in a monster ported box and make people bail.

You tried taking 25% of RMS off and doubling box size to see what they would do?
