[QUOTE="hispls, post: 8779621, member: 614752"] Coil specifications that matter, that you would need to use to have one wound at least, are inner and outer diameter, and wind width. Number of layers and gauge of wire would be useful as well. Former height and thickness you would need to know as well. Anyway, good way to estimate thermal power handling of your coil is 100W X diameter (in inches) X layers. Generally speaking 3" 4 layer coil subs will hold 1200W more or less indefinitely. This may go up or down 20% depending on the specifics but it should get you in the neighborhood of what to expect. As far as mechanical power handling that's largely dependent on the box and application. If you don't have experience building with whatever suspension you plan to use you're going to have to just guess and be prepared to rebuild it stiffer if you wind up with it breaking prematurely.
