k I just installed a dvd player and monitor and subs and amp and all that good stuff into my car, well it was all workin perfect, everything, then all of a sudden the subs made a crackling noise then just stopped working. So I noticed my amp led was not as bright so I figured i fried the amp, so Itried a new one, it still does not work...could this be because my subs are 1200watts and the amp i tried was only 1800watts? I am really confused, all fuses are good, all speakers but the subs work, and the ground and all conections are good... idk just let me know what you guys can come up with...my aim sn is kingtuite ...if u wanna talk lol

 

Could be the rca outputs on the radio.....
