I have an exile 2400.1 at the moment, and 2 15 d4 l7s. The amp is 3kw burpable for spl, and im driving it into hard clipping for testing purposes, and these suckers wont give. I have even taken one of them out, built a box for it, and put 2kw on it with my friends jbl crown 2200.1 amp, and we have pounded on it for weeks. Takes it like a champ. If the signal is clean, i cant see why it should hold up just fine with 2kw . These are much better than last years models.. My last year models couldnt even dream of holding up with this amount of power/ abuse ive put them through. Polecat even hinted to me that they should be fine with that amount of power, so i took his advance, and havent looked back sense..
