your leads burnt because you clipped the ish out of it i fried a 9915g w/ a saz1500 and i burnt the leads right next to the former but as i tore out the old soft parts i noticed the sub had a 1 seperated spider im assuming from comp use but do a recone shouldnt run you over 120 shipped and its easy to do just have patience and read alot before you doit
my first recone was my 9515g and i did it right w/ no coil rub or nuthin and order all your glues from pink star industries.
