I took it apart when i got home from wok and a mosfet blew up inside the Head unit so it looks pritty bad, theres a huge black mark on the metal that was above the one that blew, i have to look into it farhter but from what i can tell all te wire were hooked up right so, but this thing was 7 years old and i got it used so idk what could have happpened to it before i had it, lucky i didnt cut my stock plug..
