[QUOTE="Fender85, post: 76589, member: 545201"] Well if you take a gander at the Brahma's owner manual, you will see that Adire says that the 1600W is a thermal power rating, and is not a guideline or recommendation of how much power you should use on the Brahma. Basically, it's all up to your box size. You can push the Brahma to full excursion with 1300W or with 500W, depending on box. (the larger the box, the less power required to reach a certain SPL). In a 1 cubic foot sealed box, it takes 1300W at 20 hz to push the Brahma (12") to full excursion, where as it would take 800 to push it to full excursion (once again, at 20 hz) in a 2 cubic feet box. Or if you do a 2.25 cubic feet ported box, tuned to 30 hz, the Brahma will reach full excursion at 20 hz with 500W. So it's completely possible to push two Brahma's with 1500W, just be sure to build your box accordingly.
