the Z4 is inefficent abit because of the high MMS but ti should still jam with 2kw. if you have the 12 id do about 2.25 tuned to 36 for daily. you dont need to tune that low with that large of a box. even tuned to 36 the F3 is going to be close to 28hz still plenty low.. that being said you can probably find a woofer that works better off that power. like the SSA xcon or ascent audio havoc and sundown z3
