I have a Ma Audio hard kore that i want to recone. It is a fifteen and is the 5000 watt quad voice coil 1.5 ohm version. Sorry i do not remember the model number. Any way does fi make a recone kit that i could use and would it be possible to attach an 18 inch basket? The other thing that concerns me is that it is a quad voice coil sub, if i get a recone kit would it just become and dual voice coil? Any advice and knowledge is appreciated! Thanks! And sorry for a lack of knowledge, i have never reconed a sub before!
